Android0828<十>（自定义的AlertDialog，Popup Window，Notification）

自定义Dialog 和Shape

自定义的Dialog需要先建立一个drawable放Shape来设置dialog的颜色、边框、和圆角，以下是几个属性

corners圆角率

<corners
android:bottomLeftRadius="10dp"左下角为半径为10dp的圆角
android:topLeftRadius="10dp"左上角为半径为10dp的圆角
android:topRightRadius="10dp"右上角为半径为10dp的圆角
android:bottomRightRadius="10dp"右下角为半径为10dp的圆角
android:radius="10dp"     四角都为半径为10dp的圆角
/>

solid Dialog背景颜色

<solid android:color="#BFEFFF"/>

stroke android：color边框颜色 android：width边框大小

<stroke android:color="#9AFF9A" android:width="1dp"/>

若要设置dialog背景也为圆角，需要在styles中设置dialog的theme，注意的是在dialog中添加theme

<style parent="@android:Theme.Dialog" name="NoDialogTitle">

<item name="android:windowFrame">@null</item>

<item name="android:windowNoTitle">true</item>

<item name="android:windowBackground">@android:color/transparent</item>

<item name="android:windowIsFloating">true</item>

<item name="android:windowContentOverlay">@null</item>
</style>

自定义的activity_dialog_define.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:background="@mipmap/image_girlsmall"
>

<TextView
android:id="@+id/text_dialog_define_title"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="这是自定义标题"
android:textColor="#50ff0000"
android:gravity="center"
android:padding="10dp"
android:background="@drawable/bac_dialog_define"/>
<TextView
android:id="@+id/text_dialog_define_massage"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="这是自定义的内容"
android:gravity="center"
android:padding="20dp"/>

<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<Button
android:id="@+id/btn_dialog_cannel"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="cannel"
android:background="@drawable/bac_dialog_btn_anncel"/>
<Button
android:id="@+id/btn_dialog_sure"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1"
android:text="OK"
android:background="@drawable/bac_dialog_sure"/>
</LinearLayout>
</LinearLayout>

修改的主题styles

<resources>

<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- Customize your theme here. -->
</style>
<style parent="@android:Theme.Dialog" name="NoDialogTitle">

<item name="android:windowFrame">@null</item>

<item name="android:windowNoTitle">true</item>

<item name="android:windowBackground">@android:color/transparent</item>

<item name="android:windowIsFloating">true</item>

<item name="android:windowContentOverlay">@null</item>
</style>

</resources>

设置背景圆角以及按钮形状的drawable

bac_dialog_defien.xml

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<corners android:topRightRadius="10dp" android:topLeftRadius="10dp"/>
<stroke android:color="#FFFACD" android:width="1dp"/>
<solid android:color="#FFA54F" />
</shape>

bac_dialog_btn_annel.xml

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<corners android:bottomLeftRadius="10dp"
/>
<solid android:color="#BFEFFF"/>
<stroke android:color="#9AFF9A" android:width="1dp"/>
</shape>

bac_dialog_sure.xml

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<corners android:bottomRightRadius="10dp"/>
<solid android:color="#BFEFFF"/>
<stroke android:color="#9AFF9A" android:width="1dp"/>
</shape>

activity_dialog.xml

<Button
android:id="@+id/button_dialog_define"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="自定义的Dialog"/>

AlertDialogActivity.java

private Button btn_dialog_define;
private Dialog dialog;
btn_dialog_define= (Button) findViewById(R.id.button_dialog_define);
btn_dialog_define.setOnClickListener(this);

public void onClick(View v) {
switch(v.getId()){
case R.id.button_dialog_define:
dialog_define();
break;
default:break;
}
}

private void dialog_define() {
dialog=new Dialog(AlertDialogActivity.this, R.style.NoDialogTitle);
LayoutInflater inflater=getLayoutInflater();
View dialogView=inflater.inflate(R.layout.activity_dialog_define,null);
TextView textview_title= (TextView) dialogView.findViewById(R.id.text_dialog_define_title);
TextView textview_massage= (TextView) dialogView.findViewById(R.id.text_dialog_define_massage);
Button button_cannel= (Button) dialogView.findViewById(R.id.btn_dialog_cannel);
Button button_sure= (Button) dialogView.findViewById(R.id.btn_dialog_sure);
textview_title.setText("这是新的标题");
textview_massage.setText("这是新的内容");
button_cannel.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
dialog.dismiss();
}
});
button_sure.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Toast.makeText(getApplicationContext(), "点击的是OK", Toast.LENGTH_SHORT).show();
dialog.dismiss();
}
});
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.setContentView(dialogView);
dialog.show();
}

PickerDialog

dialog不仅可以弹出对话框，还可以弹出时间日期，PickerDialog就可以实现

private void timepicker_dialog() {
mCalendar= Calendar.getInstance();
TimePickerDialog timePickerDialog=new TimePickerDialog(AlertDialogActivity.this, new TimePickerDialog.OnTimeSetListener() {
@Override
public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
mCalendar.set(Calendar.HOUR,hourOfDay);
mCalendar.set(Calendar.MINUTE,minute);

SimpleDateFormat format=new SimpleDateFormat("yyyy年MM月dd日HH:mm");
format.format(mCalendar.getTime());
Toast.makeText(getApplicationContext(), "这个造型是" + format.format(mCalendar.getTime()), Toast.LENGTH_SHORT).show();
}
},mCalendar.get(Calendar.HOUR),mCalendar.get(Calendar.MINUTE),true);
timePickerDialog.show();
}

private void datepicker_dialog() {
mCalendar= Calendar.getInstance();
final DatePickerDialog pickerDialog=new DatePickerDialog(AlertDialogActivity.this, new DatePickerDialog.OnDateSetListener() {
@Override
public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
mCalendar.set(year,monthOfYear,dayOfMonth);
SimpleDateFormat format=new SimpleDateFormat("yyyy年MM月dd日");
format.format(mCalendar.getTime());
Toast.makeText(getApplicationContext(), "这个造型是" + format.format(mCalendar.getTime()), Toast.LENGTH_SHORT).show();
}
},mCalendar.get(Calendar.YEAR),mCalendar.get(Calendar.MONTH),mCalendar.get(Calendar.DAY_OF_MONTH));
pickerDialog.show();
}

PopupWindow

需要设置XML来放要显示的内容

setWidth设置宽度

setHeight设置高度

setContentView

setFocusable

setOutsideTouchable

showAsDropDown

Notification

·通知是出现在状态栏的提醒机制

·当用户打开它之后，会显示信息，还可以和用户进行交互，并处理用户选择事件

·Notification使用NotificationManager来管理

·创建一个Notification的步骤如下

1、得到NotificationManager的引用

2、初始化一个Notification的对象

3、设置Notification的参数

4、使用NotificationManager的notify（int，Notification）方法发出通知
