还算简单，先发个图看看效果。

主文件：

import android.app.Activity;

import android.os.Bundle;

import android.view.animation.AnimationUtils;

import android.widget.ViewFlipper;

public class TextAnimationActivity extends Activity {

/** Called when the activity is first created. */

@Override

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.main);

ViewFlipper viewFilpper = (ViewFlipper) findViewById(R.id.flipper);

viewFilpper.setInAnimation(AnimationUtils.loadAnimation(this,

R.anim.push_in));

viewFilpper.setOutAnimation(AnimationUtils.loadAnimation(this,

R.anim.push_out));

viewFilpper.startFlipping();

}

}

anim文件：push_in.xml

<?xml version="1.0" encoding="utf-8"?>

<set xmlns:android="http://schemas.android.com/apk/res/android">

<translate

android:fromYDelta="100"

android:toYDelta="0"

android:duration="3000" />

<alpha

android:fromAlpha="0.0"

android:toAlpha="1.0"

android:duration="3000" />

</set>

push_out.xml

<?xml version="1.0" encoding="utf-8"?>

<set xmlns:android="http://schemas.android.com/apk/res/android">

<translate

android:fromYDelta="0"

android:toYDelta="-100"

android:duration="500" />

<alpha

android:fromAlpha="1.0"

android:toAlpha="0.0"

android:duration="500" />

</set>
