底部菜单布局+PopupWindows实现弹出菜单功能(初级篇)

http://blog.csdn.net/eastmount/article/details/40827939?utm_source=tuicool

这篇文章主要是自己研究如何对底部菜单进行布局,并简单的实现点击不同"按钮"实现图片切换和背景切换的功能,最后通过PopupWindows实现弹出菜单,点击不同按钮能实现不同方法,相当于美图秀秀编辑图片的功能吧!它并没有涉及到Fragment碎片切换页面的功能,因为页面始终显示被处理的图片.这是我初学Android的一篇基础性文章和在线思想笔记,网上有很多更优秀的demo,不过也希望对大家有用~

首先介绍两种方法实现底部菜单点击不同图标显示选中状态的效果.

(可参考简短文章： Android_UI_点击按钮切换背景效果实现

)

一. 底部菜单 第一种方法

它显示的效果如下图所示,其中底部菜单布局采用多个LinearLayout进行,点击不同"按钮"可以改变其背景图片.







首先介绍它的activity_main.xml布局：

1.它采用3个RelativeLayout相对布局进行,分别对应标题路径、中间显示图片和底部的菜单栏;

2.底部菜单栏由5个LinearLayout水平布局组成,每一个LinearLayout都由ImageView和TextView组成.

代码如下：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.example.touchimagetest.MainActivity"
tools:ignore="MergeRootFrame" >
<!-- 顶部路径 -->
<RelativeLayout
android:id="@+id/MyLayout_top"
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="40dp"
android:layout_alignParentTop="true"
android:gravity="center">
<TextView
android:id="@+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="15sp"
android:text="显示图片操作" />
</RelativeLayout>
<!-- 底部按钮 -->
<RelativeLayout
android:id="@+id/MyLayout_bottom"
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="50dp"
android:layout_alignParentBottom="true"
android:background="@drawable/image_toolbar_bg"
android:gravity="center">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal"
android:layout_alignParentBottom="true" >

<LinearLayout
android:id="@+id/layout_watch"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:gravity="center"
android:orientation="vertical" >
<ImageView
android:id="@+id/image_watch"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="3dp"
android:src="@drawable/tab_watch_btn" />
<TextView
android:id="@+id/textview_watch"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="查看"
android:textColor="#ffffff"
android:textSize="10sp" />
</LinearLayout>

<LinearLayout
android:id="@+id/layout_increase"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:gravity="center"
android:orientation="vertical" >
<ImageView
android:id="@+id/image_increase"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="3dp"
android:src="@drawable/tab_increase_btn" />
<TextView
android:id="@+id/textview_increase"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="增强"
android:textColor="#ffffff"
android:textSize="10sp" />
</LinearLayout>

<LinearLayout
android:id="@+id/layout_effect"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:gravity="center"
android:orientation="vertical" >
<ImageView
android:id="@+id/image_effect"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="3dp"
android:src="@drawable/tab_effect_btn" />
<TextView
android:id="@+id/textview_effect"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="特效"
android:textColor="#ffffff"
android:textSize="10sp" />
</LinearLayout>
<LinearLayout
android:id="@+id/layout_frame"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:gravity="center"
android:orientation="vertical" >
<ImageView
android:id="@+id/image_frame"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="3dp"
android:src="@drawable/tab_frame_btn" />
<TextView
android:id="@+id/textview_frame"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="相框"
android:textColor="#ffffff"
android:textSize="10sp" />
</LinearLayout>
<LinearLayout
android:id="@+id/layout_person"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:gravity="center"
android:orientation="vertical" >
<ImageView
android:id="@+id/image_person"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="3dp"
android:src="@drawable/tab_person_btn" />
<TextView
android:id="@+id/textview_person"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="美白"
android:textColor="#ffffff"
android:textSize="10sp" />
</LinearLayout>
</LinearLayout>
</RelativeLayout>
<!-- 显示图片 -->
<RelativeLayout
android:id="@+id/Content_Layout"
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_above="@id/MyLayout_bottom"
android:layout_below="@id/MyLayout_top"
android:background="#EFDFDF"
android:gravity="center">
<ImageView
android:id="@+id/imageView1"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_gravity="center_horizontal"
android:scaleType="matrix" />
</RelativeLayout>
</RelativeLayout>

此时你需要注意的是为每个LinearLayout中ImageView指定src时并不是原图片,而是drawable中的xml文件,如<ImageView android:id="@+id/image_watch".. />.



同时每个drawable中的xml文件对应每个相应的按钮,上图中effect(效果)、increase(增强)、frame(相框)、watch(查看)、person(美白).其中每个格式基本如下,如tab_watch_btn.xml：

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:drawable="@drawable/image_icon_watch_sel" android:state_selected="true"/>
<item android:drawable="@drawable/image_icon_watch_sel" android:state_pressed="true"/>
<item android:drawable="@drawable/image_icon_watch_nor"/>
</selector>

其中state_selected表示"选中"状态,state_pressed表示"点击"效果,而最后的<item android:drawable="@drawable/image_icon_watch_nor"/> 表示默认情况显示图片,原图片如下：



同时设置选中状态"按钮"的背景加黑效果,在drawable中添加selector_tab_background.xml文件:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:drawable="@drawable/image_home_layout_bg" android:state_pressed="true"/>
<item android:drawable="@drawable/image_home_layout_bg" android:state_selected="true"/>
</selector>

//自定义变量
private LinearLayout layoutWatch;             //查看图片
private LinearLayout layoutIncrease;           //增强图片
private LinearLayout layoutEffect;               //图片特效
private LinearLayout layoutFrame;              //图片边框
private LinearLayout layoutPerson;             //图片美白

private ImageView imageWatch;
private ImageView imageIncrease;
private ImageView imageEffect;
private ImageView imageFrame;
private ImageView imagePerson;

//创建活动
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//布局
layoutWatch = (LinearLayout) findViewById(R.id.layout_watch);
layoutIncrease = (LinearLayout) findViewById(R.id.layout_increase);
layoutEffect = (LinearLayout) findViewById(R.id.layout_effect);
layoutFrame = (LinearLayout) findViewById(R.id.layout_frame);
layoutPerson = (LinearLayout) findViewById(R.id.layout_person);
//图标
imageWatch = (ImageView) findViewById(R.id.image_watch);
imageIncrease = (ImageView) findViewById(R.id.image_increase);
imageEffect = (ImageView) findViewById(R.id.image_effect);
imageFrame = (ImageView) findViewById(R.id.image_frame);
imagePerson = (ImageView) findViewById(R.id.image_person);
//初始化布局
initView();

//按钮一 监听事件 查看图片
layoutWatch.setOnClickListener( new OnClickListener() {
@Override
public void onClick(View v) {
//设置背景图片加深
Toast.makeText(MainActivity.this, "点击按钮1", Toast.LENGTH_SHORT).show();
layoutWatch.setBackgroundResource(R.drawable.selector_tab_background);
//设置图标选中情况
layoutWatch.setSelected(true);
layoutIncrease.setSelected(false);
layoutEffect.setSelected(false);
layoutFrame.setSelected(false);
layoutPerson.setSelected(false);
}
});
//按钮二 监听事件增强图片
layoutIncrease = (LinearLayout) findViewById(R.id.layout_increase);
layoutIncrease.setOnClickListener( new OnClickListener() {
@Override
public void onClick(View v) {
layoutIncrease.setBackgroundResource(R.drawable.selector_tab_background);
//设置图标选中情况
layoutWatch.setSelected(false);
layoutIncrease.setSelected(true);
layoutEffect.setSelected(false);
layoutFrame.setSelected(false);
layoutPerson.setSelected(false);
}
});
//按钮三 监听事件图片特效
layoutEffect = (LinearLayout) findViewById(R.id.layout_effect);
layoutEffect.setOnClickListener( new OnClickListener() {
@Override
public void onClick(View v) {
//设置背景图片
layoutEffect.setBackgroundResource(R.drawable.selector_tab_background);
//设置图标选中情况
layoutWatch.setSelected(false);
layoutIncrease.setSelected(false);
layoutEffect.setSelected(true);
layoutFrame.setSelected(false);
layoutPerson.setSelected(false);
}
});
//按钮四 监听事件图片相框
layoutFrame = (LinearLayout) findViewById(R.id.layout_frame);
layoutFrame.setOnClickListener( new OnClickListener() {
@Override
public void onClick(View v) {
//设置背景图片
layoutFrame.setBackgroundResource(R.drawable.selector_tab_background);
//设置图标选中情况
layoutWatch.setSelected(false);
layoutIncrease.setSelected(false);
layoutEffect.setSelected(false);
layoutFrame.setSelected(true);
layoutPerson.setSelected(false);

}
});
//按钮五 监听事件图片美白
layoutPerson = (LinearLayout) findViewById(R.id.layout_person);
layoutPerson.setOnClickListener( new OnClickListener() {
@Override
public void onClick(View v) {
//设置背景图片
layoutPerson.setBackgroundResource(R.drawable.selector_tab_background);
//设置图标选中情况
layoutWatch.setSelected(false);
layoutIncrease.setSelected(false);
layoutEffect.setSelected(false);
layoutFrame.setSelected(false);
layoutPerson.setSelected(true);

}
});
}

//初始化布局
private void initView()
{
imageWatch.setImageResource(R.drawable.tab_watch_btn);
imageIncrease.setImageResource(R.drawable.tab_increase_btn);
imageEffect.setImageResource(R.drawable.tab_effect_btn);
imageFrame.setImageResource(R.drawable.tab_frame_btn);
imagePerson.setImageResource(R.drawable.tab_person_btn);
}

二. 底部菜单 第二种方法

其中activity_main.xml中布局与第一个相同,不同的是在xml中就指定drawable-hdpi中原图片名,因为它不在调用drawable如 tab_watch_btn.xml文件,而使用代码直接操作. 其中5个LinearLayout一个如下所示：

<LinearLayout
android:id="@+id/layout_watch"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:gravity="center"
android:orientation="vertical" >
<ImageView
android:id="@+id/image_watch"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="3dp"
android:src="@drawable/image_icon_watch_nor" />
<TextView
android:id="@+id/textview_watch"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="查看"
android:textColor="#ffffff"
android:textSize="10sp" />
</LinearLayout>

此时它的文件夹结构如下图,drawble没有设置背景加深和加载图标的xml文件：



同时5个LinearLayout(查看、增强、特效、相框、美白)设置触屏响应事件：

layoutWatch.setOnTouchListener(new OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
if(event.getAction() == MotionEvent.ACTION_DOWN) {
//按下背景图片
layoutWatch.setBackgroundResource(R.drawable.image_home_layout_bg);
layoutIncrease.setBackgroundResource(R.drawable.image_home_layout_no);
layoutEffect.setBackgroundResource(R.drawable.image_home_layout_no);
layoutFrame.setBackgroundResource(R.drawable.image_home_layout_no);
layoutPerson.setBackgroundResource(R.drawable.image_home_layout_no);
//设置按钮图片
imageWatch.setImageDrawable(getResources().getDrawable(R.drawable.image_icon_watch_sel));
imageIncrease.setImageDrawable(getResources().getDrawable(R.drawable.image_icon_increase_nor));
imageEffect.setImageDrawable(getResources().getDrawable(R.drawable.image_icon_effect_nor));
imageFrame.setImageDrawable(getResources().getDrawable(R.drawable.image_icon_frame_nor));
imagePerson.setImageDrawable(getResources().getDrawable(R.drawable.image_icon_person_nor));
}
return false;
}
});

需要注意的是网上下面这段代码仅实现点击一下图片变换的效果,而如果想要实现长显需要如我上面的所示.还见到一个使用Radio实现该效果,当点击一次时判断是否选中并显示相应图片.而使用FragmentTabHost实现同样效果,我不知其原理~

bottomReturnBtn.setOnTouchListener(new OnTouchListener() {
//这段代码仅仅实现点击一次改变图标功能
public boolean onTouch(View v, MotionEvent event) {
Button upStepBtn = (Button) v;
if(event.getAction() == MotionEvent.ACTION_DOWN){
upStepBtn.setBackgroundResource(R.drawable.bottom_sub_order_btn);
}else if(event.getAction() == MotionEvent.ACTION_UP){
upStepBtn.setBackgroundResource(R.drawable.bottom_return_check);
finish();
}
return false;
}
});

三. PopupWindow实现弹出菜单

然后讲解如何通过PopupWindow实现下面的功能.效果如下图所示,简单实现PopupWindow功能可结合下面两篇文章：

android之popupWindow在指定位置上的显示

[android开发] 使用PopupWindow实现页面点击顶部弹出下拉菜单






首先,为PopupWindow设置动画效果,在res文件夹下添加文件夹anim,然后添加anim_entry.xml文件：

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<translate
android:fromXDelta="0"
android:toXDelta="0"
android:fromYDelta="120"
android:toYDelta="0"
android:duration="500" />
</set>

它是出现效果：从菜单栏底部向上弹出,同时添加anim_exit.xml:

<?xml version="1.0" encoding="UTF-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" >
<!-- 透明度消失 -->
<alpha
android:fromAlpha="1.0"
android:toAlpha="0.0"
android:duration="200" />
</set>

最后在res/values文件夹styles.xml中添加动画效果,通过调用name="AnimationPreview"可以实现动画：

<!-- 定义popupwindows动画效果 -->
<style name="AnimationPreview">
<item name="android:windowEnterAnimation">@anim/anim_entry</item>
<item name="android:windowExitAnimation">@anim/anim_exit</item>
</style>

然后你需要自定义弹出PopupWindow的布局xml文件,如popup_effect.xml：

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content" >

<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:background="@drawable/image_button_bg_left"
android:orientation="vertical" >
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:layout_marginTop="5dp"
android:orientation="horizontal" >

<LinearLayout
android:id="@+id/layout_effect_hj"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="2dp"
android:layout_weight="1"
android:orientation="vertical" >
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:layout_marginTop="1.0dip"
android:src="@drawable/image_effect_hj" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:layout_marginTop="1.0dip"
android:shadowColor="#ff000000"
android:shadowDx="1.0"
android:shadowDy="1.0"
android:shadowRadius="1.0"
android:text="怀旧"
android:textColor="#ffffffff"
android:textSize="13.0dip" />
</LinearLayout>

<LinearLayout
android:id="@+id/layout_effect_fd"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="2dp"
android:layout_weight="1"
android:orientation="vertical" >
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:layout_marginTop="1.0dip"
android:src="@drawable/image_effect_fd" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:layout_marginTop="1.0dip"
android:shadowColor="#ff000000"
android:shadowDx="1.0"
android:shadowDy="1.0"
android:shadowRadius="1.0"
android:text="浮雕"
android:textColor="#ffffffff"
android:textSize="13.0dip" />
</LinearLayout>

<LinearLayout
android:id="@+id/layout_effect_gz"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="2dp"
android:layout_weight="1"
android:orientation="vertical" >
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:layout_marginTop="1.0dip"
android:src="@drawable/image_effect_gz" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:layout_marginTop="1.0dip"
android:shadowColor="#ff000000"
android:shadowDx="1.0"
android:shadowDy="1.0"
android:shadowRadius="1.0"
android:text="光照"
android:textColor="#ffffffff"
android:textSize="13.0dip" />
</LinearLayout>

<LinearLayout
android:id="@+id/layout_effect_sm"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="2dp"
android:layout_weight="1"
android:orientation="vertical" >
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:layout_marginTop="1.0dip"
android:src="@drawable/image_effect_sm" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:layout_marginTop="1.0dip"
android:shadowColor="#ff000000"
android:shadowDx="1.0"
android:shadowDy="1.0"
android:shadowRadius="1.0"
android:text="素描"
android:textColor="#ffffffff"
android:textSize="13.0dip" />
</LinearLayout>

<LinearLayout
android:id="@+id/layout_effect"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="2dp"
android:layout_weight="1"
android:orientation="vertical" >
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:layout_marginTop="1.0dip"
android:src="@drawable/image_effect" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:layout_marginTop="1.0dip"
android:shadowColor="#ff000000"
android:shadowDx="1.0"
android:shadowDy="1.0"
android:shadowRadius="1.0"
android:text="锐化"
android:textColor="#ffffffff"
android:textSize="13.0dip" />
</LinearLayout>
</LinearLayout>
</LinearLayout>
</RelativeLayout>

它的在Xml中Graphical Layout显示效果如下图所示：




添加5个自定义变量：

//弹出按钮
private PopupWindow popupWindow1;
private PopupWindow popupWindow2;
private PopupWindow popupWindow3;
private PopupWindow popupWindow4;
private PopupWindow popupWindow5;

然后当点击"相框"布局LinearLayout时,添加代码如下(其他类似)：

//按钮四 监听事件图片相框
layoutFrame.setOnClickListener( new OnClickListener() {
@Override
public void onClick(View v) {
//载入PopupWindow
if (popupWindow4 != null&&popupWindow4.isShowing()) {
popupWindow4.dismiss();
return;
} else {
initmPopupWindowView(4);   //number=4
int[] location = new int[2];
v.getLocationOnScreen(location);
Toast.makeText(MainActivity.this, ""+location[0], Toast.LENGTH_SHORT).show();
popupWindow4.showAtLocation(v, Gravity.NO_GRAVITY, location[0], location[1]-popupWindow4.getHeight());
}
}
});

其中initmPopupWindowView(int number)为自定义函数,参数对应的是点击LinearLayout的序号,点击"按钮"4即传入数字4：

public void initmPopupWindowView(int number) {
View customView = null;
// 获取自定义布局文件
if(number==1) { //查看
customView = getLayoutInflater().inflate(R.layout.popup_watch, null, false);
// 创建PopupWindow实例  (250,180)分别是宽度和高度
popupWindow1 = new PopupWindow(customView, 250, 280);
// 设置动画效果 [R.style.AnimationFade 是自己事先定义好的]
popupWindow1.setAnimationStyle(R.style.AnimationPreview);
// 自定义view添加触摸事件
customView.setOnTouchListener(new OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
if (popupWindow1 != null && popupWindow1.isShowing()) {
popupWindow1.dismiss();
popupWindow1 = null;
}
return false;
}
});
}
if(number==2) { //增强
customView = getLayoutInflater().inflate(R.layout.popup_increase, null, false);
popupWindow2 = new PopupWindow(customView, 450, 150);
// 使其聚集 要想监听菜单里控件的事件就必须要调用此方法
popupWindow2.setFocusable(true);
// 设置允许在外点击消失
popupWindow2.setOutsideTouchable(true);
popupWindow2.setAnimationStyle(R.style.AnimationPreview);
// 自定义view添加触摸事件
customView.setOnTouchListener(new OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
if (popupWindow2 != null && popupWindow2.isShowing()) {
popupWindow2.dismiss();
popupWindow2 = null;
}
return false;
}
});
}
if(number==3) { //效果
customView = getLayoutInflater().inflate(R.layout.popup_effect, null, false);
popupWindow3 = new PopupWindow(customView, 450, 150);
// 使其聚集 要想监听菜单里控件的事件就必须要调用此方法
popupWindow3.setFocusable(true);
// 设置允许在外点击消失
popupWindow3.setOutsideTouchable(true);
popupWindow3.setAnimationStyle(R.style.AnimationPreview);
// 自定义view添加触摸事件
customView.setOnTouchListener(new OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
if (popupWindow3 != null && popupWindow3.isShowing()) {
popupWindow3.dismiss();
popupWindow3 = null;
}
return false;
}
});
}
if(number==4) {
customView = getLayoutInflater().inflate(R.layout.popup_frame, null, false);
popupWindow4 = new PopupWindow(customView, 450, 150);
// 使其聚集 要想监听菜单里控件的事件就必须要调用此方法
popupWindow4.setFocusable(true);
popupWindow4.setAnimationStyle(R.style.AnimationPreview);
// 自定义view添加触摸事件
customView.setOnTouchListener(new OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
if (popupWindow4 != null && popupWindow4.isShowing()) {
popupWindow4.dismiss();
popupWindow4 = null;
}
return false;
}
});
}
if(number==5) {
customView = getLayoutInflater().inflate(R.layout.popup_frame, null, false);
popupWindow5 = new PopupWindow(customView, 450, 150);
// 使其聚集 要想监听菜单里控件的事件就必须要调用此方法
popupWindow5.setFocusable(true);
popupWindow5.setAnimationStyle(R.style.AnimationPreview);
// 自定义view添加触摸事件
customView.setOnTouchListener(new OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
if (popupWindow5 != null && popupWindow5.isShowing()) {
popupWindow5.dismiss();
popupWindow5 = null;
}
return false;
}
});
} //end if
}

四. PopupWindow实现点击效果

做到这里,你就能实现点击底部菜单实现弹出PopupWindows效果,但显然是不足的.怎样通过点击弹出PopupWindow中的按钮实现做不同的事情呢?下面讲解,你只需要添加下面的代码即可实现"特效"效果.








代码如下,你可以自定义函数实现不同效果功能(结合前面几篇文章,我的美图秀秀基本完成)：

if(number==3) { //效果
customView = getLayoutInflater().inflate(R.layout.popup_effect, null, false);
popupWindow3 = new PopupWindow(customView, 450, 150);
// 使其聚集 要想监听菜单里控件的事件就必须要调用此方法
popupWindow3.setFocusable(true);
// 设置允许在外点击消失
popupWindow3.setOutsideTouchable(true);
popupWindow3.setAnimationStyle(R.style.AnimationPreview);
// 自定义view添加触摸事件
customView.setOnTouchListener(new OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
if (popupWindow3 != null && popupWindow3.isShowing()) {
popupWindow3.dismiss();
popupWindow3 = null;
}
return false;
}
});
//判断点击子菜单不同按钮实现不同功能
LinearLayout layoutEffect1 = (LinearLayout) customView.findViewById(R.id.layout_effect_hj);
layoutEffect1.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
Toast.makeText(MainActivity.this, "效果-怀旧", Toast.LENGTH_SHORT).show();
}
});
LinearLayout layoutEffect2 = (LinearLayout) customView.findViewById(R.id.layout_effect_fd);
layoutEffect2.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
Toast.makeText(MainActivity.this, "效果-浮雕", Toast.LENGTH_SHORT).show();
}
});
LinearLayout layoutEffect3 = (LinearLayout) customView.findViewById(R.id.layout_effect_gz);
layoutEffect3.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
Toast.makeText(MainActivity.this, "效果-光照", Toast.LENGTH_SHORT).show();
}
});
LinearLayout layoutEffect4 = (LinearLayout) customView.findViewById(R.id.layout_effect_sm);
layoutEffect4.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
Toast.makeText(MainActivity.this, "效果-素描", Toast.LENGTH_SHORT).show();
//打开图片
OpenImage();
}
});
LinearLayout layoutEffect5 = (LinearLayout) customView.findViewById(R.id.layout_effect);
layoutEffect5.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
Toast.makeText(MainActivity.this, "效果-锐化", Toast.LENGTH_SHORT).show();
}
});
}

五. 总结

本文章主要讲述如何加载菜单栏在底部,同时讲述PopupWindows弹出事件,其实更好的布局方法是通过适配器,但是我才学Android,很多东西还不懂.所以它只是一篇初级文章,但完全能实现需要功能.

Android之用PopupWindow实现弹出菜单

最后希望文章对大家有所帮助,如果文章中有错误或不足之处见谅~
