最近看到ViewFlipper和Animation在一起的用法，感觉很好，我就自己写了一下，感觉灰常好用，效果比gallery的滚动查看图片好用多了，这个也是实现滚动屏幕切换图片，但是用户体验要好很多！所以我把自己写的demo分享一下！希望对大家有用，也方便我自己以后查阅！转载请标明出处：

程序一开始界面，第一张图片： 向右滑动屏幕切换到第二张图片：
向右滑动切换第三张图片：
向左滑动就又切换到第二张图片了！
以此类推！
代码奉上：
一、MainActivity。java类文件：
package com.cn.daming;
import android.app.Activity;
import android.content.Intent;
import android.graphics.Color;
import android.graphics.drawable.GradientDrawable;
import android.graphics.drawable.GradientDrawable.Orientation;
import android.os.Bundle;
import android.util.Log;
import android.view.GestureDetector;
import android.view.GestureDetector.OnGestureListener;
import android.view.LayoutInflater;
import android.view.MotionEvent;
import android.view.View;
import android.view.animation.AnimationUtils;
import android.widget.ViewFlipper;
public class MainActivity extends Activity implements OnGestureListener{
private GestureDetector detector;
private ViewFlipper flipper;
private final int HELPFILP_RESULT = 106;
Intent getMainActivity = null;
int count = 1;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
drawBackground();
LayoutInflater inflater = LayoutInflater.from(this);
final View layout = inflater.inflate(R.layout.view_flipper, null);
setContentView(layout);
flipper = (ViewFlipper) findViewById(R.id.view_flipper);
detector = new GestureDetector(this);
}
public void drawBackground()
{
GradientDrawable grad = new GradientDrawable(
Orientation.TL_BR,
new int[] {Color.rgb(0, 0, 127),
Color.rgb(0, 0, 255),
Color.rgb(127, 0, 255),
Color.rgb(127, 127, 255),
Color.rgb(127, 255, 255),
Color.rgb(255, 255, 255)}
);
this.getWindow().setBackgroundDrawable(grad);
}
@Override
public boolean onTouchEvent(MotionEvent event) {
return this.detector.onTouchEvent(event);
}
public boolean onDown(MotionEvent arg0) {
// TODO Auto-generated method stub
return false;
}
public boolean onFling(MotionEvent e1, MotionEvent e2, float arg2,
float arg3) {
Log.i("Fling", "Fling Happened!");
if (e1.getX() - e2.getX() > 5) {
this.flipper.setInAnimation(AnimationUtils.loadAnimation(this,
R.anim.push_left_in));
this.flipper.setOutAnimation(AnimationUtils.loadAnimation(this,
R.anim.push_left_out));
if (count < 3) {
this.flipper.showNext();
count++;
}
return true;
} else if (e1.getX() - e2.getX() < -5) {
this.flipper.setInAnimation(AnimationUtils.loadAnimation(this,
R.anim.push_right_in));
this.flipper.setOutAnimation(AnimationUtils.loadAnimation(this,
R.anim.push_right_out));
if (count > 1) {
this.flipper.showPrevious();
count--;
}
return true;
}
return true;
}
public void onLongPress(MotionEvent arg0) {
// TODO Auto-generated method stub
}
public boolean onScroll(MotionEvent arg0, MotionEvent arg1, float arg2,
float arg3) {
// TODO Auto-generated method stub
return false;
}
public void onShowPress(MotionEvent arg0) {
// TODO Auto-generated method stub
}
public boolean onSingleTapUp(MotionEvent arg0) {
// TODO Auto-generated method stub
return false;
}
}
二、view_flipper.xml布局文件
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/layout" android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="fill_parent" > <ViewFlipper android:id="@+id/view_flipper" android:layout_width="fill_parent" android:layout_height="fill_parent" android:persistentDrawingCache="animation" android:flipInterval="1000" android:inAnimation="@anim/push_left_in" android:outAnimation="@anim/push_left_out"> <LinearLayout android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="fill_parent"> <ImageView android:id="@+id/view_bg1" android:src="@drawable/bg1" android:layout_width="fill_parent" android:layout_height="fill_parent" > </ImageView> </LinearLayout> <LinearLayout android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="fill_parent"> <ImageView android:id="@+id/view_bg2" android:src="@drawable/bg2" android:layout_width="fill_parent" android:layout_height="fill_parent" > </ImageView> </LinearLayout> <LinearLayout android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="fill_parent"> <ImageView android:id="@+id/view_bg3" android:src="@drawable/bg3" android:layout_width="fill_parent" android:layout_height="fill_parent" > </ImageView> </LinearLayout> </ViewFlipper> </LinearLayout>
三、anim动画布局文件：
1、push_left_in.xml布局文件：
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<translate android:fromXDelta="100%p" android:toXDelta="0"
android:duration="500" />
<alpha android:fromAlpha="0.1" android:toAlpha="1.0"
android:duration="500" />
</set>
2、push_left_out.xml布局文件
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<translate android:fromXDelta="0" android:toXDelta="-100%p"
android:duration="500" />
<alpha android:fromAlpha="1.0" android:toAlpha="0.1"
android:duration="500" />
</set>
3、push_right_in.xml布局文件
<?xml version="1.0" encoding="UTF-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<translate android:fromXDelta="-100%p" android:toXDelta="0"
android:duration="500" />
<alpha android:fromAlpha="0.1" android:toAlpha="1.0"
android:duration="500" />
</set>
4、push_right_out.xml布局文件
<?xml version="1.0" encoding="UTF-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<translate android:fromXDelta="0" android:toXDelta="100%p"
android:duration="500" />
<alpha android:fromAlpha="1.0" android:toAlpha="0.1"
android:duration="500" />
</set>
