直接上代码（来自 android范例大全这本书）

布局文件 4 个

//anim_alpha.xml<?xml version="1.0" encoding="utf-8"?><set xmlns:android="http://schemas.android.com/apk/res/android"><alpha android:fromAlpha="1"    android:toAlpha="0"    android:fillAfter="true"    android:repeatMode="reverse"    android:repeatCount="1"    android:duration="2000"/></set>

// 入口activity

package com.myapplicatio10.wheee.myapplication10;import android.app.Activity;import android.os.Bundle;import android.view.View;import android.view.animation.Animation;import android.view.animation.AnimationUtils;import android.widget.Button;import android.widget.ImageView;public class MainActivity extends Activity {    /**     * Called when the activity is first created.     */    @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        final Animation rotate = AnimationUtils.loadAnimation(this, R.anim.anim_rotate);    //获取“旋转”动画资源        final Animation translate = AnimationUtils.loadAnimation(this, R.anim.anim_translate);    //获取“平移”动画资源        final Animation scale = AnimationUtils.loadAnimation(this, R.anim.anim_scale);    //获取“缩放”动画资源        final Animation alpha = AnimationUtils.loadAnimation(this, R.anim.anim_alpha);    //获取“透明度变化”动画资源        final ImageView iv = (ImageView) findViewById(R.id.imageView1);    //获取要应用动画效果的ImageView        final  Button button1 = (Button) findViewById(R.id.button1);    //获取“旋转”按钮        button1.setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View v) {                button1 .startAnimation(translate);    //播放“平移”动画                iv.startAnimation(scale);    //播放“缩放”动画            }        });        Button button2 = (Button) findViewById(R.id.button2);    //获取“平移”按钮        button2.setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View v) {                iv.startAnimation(translate);    //播放“平移”动画            }        });        Button button3 = (Button) findViewById(R.id.button3);    //获取“缩放”按钮        button3.setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View v) {                iv.startAnimation(scale);    //播放“缩放”动画            }        });        Button button4 = (Button) findViewById(R.id.button4);    //获取“透明度渐变”按钮        button4.setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View v) {                iv.startAnimation(alpha);    //播放“透明度渐变”动画            }        });    }}//        FrameLayout frameLayout = (FrameLayout) findViewById(R.id.f_1);//        MyClass myClass = new MyClass(this);//        frameLayout.addView(myClass);

即可实现。
