xml布局：
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:andro >
<ViewSwitcher
android: >
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content" >
<TextView
android:layout_width="fill_parent"
android:layout_height="100dp"
android:background="#123456"
android:text="11111111"
android:textSize="32sp" >
</TextView>
</RelativeLayout>
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content" >
<TextView
android:layout_width="fill_parent"
android:layout_height="100dp"
android:background="#FFFFFFFF"
android:text="22222222"
android:textSize="32sp" >
</TextView>
</RelativeLayout>
</ViewSwitcher>
<Button
android: />
<Button
android: />
</LinearLayout>
自定义的动画，也可以用系统自带的，在@android:anim/目录：
slide_in_top.xml
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:andro >
<translate
android:duration="2000"
android:fromYDelta="-100%p"
android:toYDelta="0" />
</set>
slide_in_bottom.xml
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:andro >
<translate
android:duration="2000"
android:fromYDelta="0"
android:toYDelta="100%p" />
</set>
Java代码：
package com.arnold.activity;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.ViewSwitcher;
public class MainActivity extends Activity {
/** Called when the activity is first created. */
private ViewSwitcher mSwitcher;
private Button btn_prev, btn_next;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
mSwitcher = (ViewSwitcher) findViewById(R.id.switcher);
mSwitcher.setDisplayedChild(0);
btn_next = (Button) findViewById(R.id.next);
btn_prev = (Button) findViewById(R.id.prev);
btn_next.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
mSwitcher.showNext();
}
});
btn_prev.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
mSwitcher.showPrevious();
}
});
}
}
注意：ViewSwitcher只可以在两种布局中切换，ViewFlipper可以应用多种布局，用法基本一样但后者多出几个方法：
isFlipping：用来判断View切换是否正在进行
setFilpInterval：设置View之间切换的时间间隔
startFlipping：使用上面设置的时间间隔来开始切换所有的View，切换会循环进行
stopFlipping：停止View切换
