//=============主页面的布局   main.xml=======================

<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"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".MainActivity" >

<ListView android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:id="@+id/lv"
        android:entries="@array/names"></ListView>
    <Button android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="跳转页面"
        android:layout_below="@+id/lv"
        android:onClick="go2Other"/>

</RelativeLayout>

//=========此为 values包下的string.xml   中添加的====是Listview展示的条目内容================

<string-array name="names">
        <item>张三1</item>
        <item>张三2</item>
        <item>张三3</item>
        <item>张三4</item>
        <item>张三5</item>
        <item>张三6</item>
        <item>张三7</item>
        <item>张三8</item>
        <item>张三9</item>
    </string-array>

//=======此为在res 包下创建一个anim  包 ,再在anim包下  创建   item_animation.xml  ===================

<?xml version="1.0" encoding="utf-8"?>
<translate  xmlns:android="http://schemas.android.com/apk/res/android"
    android:fromXDelta="-100%p"
    android:toXDelta="0"
    android:fromYDelta="0"
    android:toYDelta="0"
    android:duration="1000">

</translate>

//===========在anim包下  创建   slide_left_in.xml  ======表示左进================================

<?xml version="1.0" encoding="utf-8"?>
<translate  xmlns:android="http://schemas.android.com/apk/res/android"
    android:fromXDelta="-100%p"
    android:toXDelta="0"
    android:toYDelta="0"
    android:fromYDelta="0"
    android:duration="2000">

</translate>

//==============在anim包下  创建   slide_left_out.xml  ======表示左出====================

<?xml version="1.0" encoding="utf-8"?>
<translate  xmlns:android="http://schemas.android.com/apk/res/android"
    android:fromXDelta="0"
    android:fromYDelta="0"
    android:toXDelta="-100%p"
    android:toYDelta="0"
    android:duration="2000">

</translate>

//==========在anim包下  创建   slide_right_in.xml  ======表示右进===================

<?xml version="1.0" encoding="utf-8"?>
<translate  xmlns:android="http://schemas.android.com/apk/res/android"
    android:fromXDelta="100%p"
    android:fromYDelta="0"
    android:toXDelta="0"
    android:toYDelta="0"
    android:duration="2000">

</translate>

//============在anim包下  创建   slide_right_out.xml  ======表示右出=====================

    android:fromYDelta="0"
    android:toXDelta="100%p"
    android:toYDelta="0"
    android:duration="2000">

</translate>

//=======创建一个OtherActivity====================

import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;

public class OtherActivity extends Activity {

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_other);
    }
    @Override
    public void finish() {
        
        super.finish();
        overridePendingTransition(R.anim.slide_left_in, R.anim.slide_right_out);
    }
    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.other, menu);
        return true;
    }

}

//=========OtherActivity的布局文件没有做处理=====================

当点击button时，会淡入淡出进入OtherActivity
