Android新装应用apk运行动画 ViewFlipper(翻转视图)

其实这么个意思，就是每次我们下载一个新的应用，他都有左右滑动看这个应用的介绍，或者宣传之类的，刚开始感觉好牛逼。

今天学了这个http://blog.csdn.net/coder_pig/article/details/48734807

感觉不在那么高大上了。。

好的，我们开始学习吧

不多说了，老规矩，贴代码

每个页面的布局都是一个简单的ImageView

page_help_one.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">

<ImageView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:src="@mipmap/ic_help_view_1"/>

</LinearLayout>

page_help_two.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">

<ImageView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:src="@mipmap/ic_help_view_2"/>

</LinearLayout>

page_help_three.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">

<ImageView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:src="@mipmap/ic_help_view_3"/>

</LinearLayout>

page_help_four.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">

<ImageView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:src="@mipmap/ic_help_view_4"/>

</LinearLayout>

两个进入以及 离开的动画：

right_in.xml

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

<translate
android:duration="2000"
android:fromXDelta="100%p"
android:toXDelta="0" />

</set>

right_out.xml

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

<translate
android:duration="2000"
android:fromXDelta="0"
android:toXDelta="-100%p" />

</set>

图片就不用了吧。。。

布局文件：activity_main.xml

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

<ViewFlipper
android:id="@+id/vflp_help"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:inAnimation="@anim/right_in"
android:outAnimation="@anim/right_out"
android:flipInterval="3000">

<include layout="@layout/page_help_one" />

<include layout="@layout/page_help_two" />

<include layout="@layout/page_help_three" />

<include layout="@layout/page_help_four" />

</ViewFlipper>

</RelativeLayout>

展示视图控制文件：MainActivity

package com.yang.viewflipperstaticdemo;

import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.widget.ViewFlipper;

public class MainActivity extends AppCompatActivity {

private ViewFlipper vflp_help;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
vflp_help = (ViewFlipper) findViewById(R.id.vflp_help);
vflp_help.startFlipping();
}
}

AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.yang.viewflipperstaticdemo">

<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:supportsRtl="true"
android:theme="@style/AppTheme">
<activity
android:name=".MainActivity"
android:label="@string/app_name"
android:theme="@style/AppTheme.NoActionBar">
<intent-filter>
<action android:name="android.intent.action.MAIN" />

<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>

</manifest>

看他自己在动，十分不爽是吧

我们需要的是可操作。。

这是代码目录

再增加两个进入以及 离开的动画：

left_in.xml

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

<translate
android:duration="500"
android:fromXDelta="-100%p"
android:toXDelta="0" />

</set>

left_out.xml

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

<translate
android:duration="500"
android:fromXDelta="0"
android:toXDelta="100%p" />

</set>

新增了：MainActivityRun

package com.yang.viewflipperstaticdemo;

import android.content.Context;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.GestureDetector;
import android.view.MotionEvent;
import android.widget.ImageView;
import android.widget.ViewFlipper;

public class MainActivityRun extends AppCompatActivity {

private Context mContext;
private ViewFlipper vflp_help;
private int[] resId = {R.mipmap.ic_help_view_1,R.mipmap.ic_help_view_2,
R.mipmap.ic_help_view_3,R.mipmap.ic_help_view_4};

private final static int MIN_MOVE = 200;   //最小距离
private MyGestureListener mgListener;
private GestureDetector mDetector;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mContext = MainActivityRun.this;
//实例化SimpleOnGestureListener与GestureDetector对象
mgListener = new MyGestureListener();
mDetector = new GestureDetector(this, mgListener);
vflp_help = (ViewFlipper) findViewById(R.id.vflp_help);
//动态导入添加子View
for(int i = 0;i < resId.length;i++){
vflp_help.addView(getImageView(resId[i]));
}

}

//重写onTouchEvent触发MyGestureListener里的方法
@Override
public boolean onTouchEvent(MotionEvent event) {
return mDetector.onTouchEvent(event);
}

//自定义一个GestureListener,这个是View类下的，别写错哦！！！
private class MyGestureListener extends GestureDetector.SimpleOnGestureListener {
@Override
public boolean onFling(MotionEvent e1, MotionEvent e2, float v, float v1) {
if(e1.getX() - e2.getX() > MIN_MOVE){
vflp_help.setInAnimation(mContext,R.anim.right_in);
vflp_help.setOutAnimation(mContext, R.anim.right_out);
vflp_help.showNext();
}else if(e2.getX() - e1.getX() > MIN_MOVE){
vflp_help.setInAnimation(mContext,R.anim.left_in);
vflp_help.setOutAnimation(mContext, R.anim.left_out);
vflp_help.showPrevious();
}
return true;
}
}

private ImageView getImageView(int resId){
ImageView img = new ImageView(this);
img.setBackgroundResource(resId);
return img;
}
}

怎么么让他运行呢。。。别忘了改AndroidManifest.xml,区别自己看去吧

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.yang.viewflipperstaticdemo">

<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:supportsRtl="true"
android:theme="@style/AppTheme">
<activity
android:name=".MainActivityRun"
android:label="@string/app_name"
android:theme="@style/AppTheme.NoActionBar">
<intent-filter>
<action android:name="android.intent.action.MAIN" />

<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>

</manifest>
