试试这个希望你找到有趣的..

这是活动代码......

package test.example;

import android.app.Activity;
import android.graphics.drawable.AnimationDrawable;
import android.graphics.drawable.BitmapDrawable;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.ImageView;

public class AminationDemo extends Activity implements OnClickListener {

    ImageView img;

    Button strtbtn,stpbtn;

    AnimationDrawable mAnimation;
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        img = (ImageView) findViewById(R.id.iv);

        BitmapDrawable frame0 = (BitmapDrawable)getResources().getDrawable(R.drawable.f0);
        BitmapDrawable frame1 = (BitmapDrawable)getResources().getDrawable(R.drawable.f1);
        BitmapDrawable frame2 = (BitmapDrawable)getResources().getDrawable(R.drawable.f2);
        BitmapDrawable frame3 = (BitmapDrawable)getResources().getDrawable(R.drawable.f3);
        BitmapDrawable frame4 = (BitmapDrawable)getResources().getDrawable(R.drawable.f4);
        BitmapDrawable frame5 = (BitmapDrawable)getResources().getDrawable(R.drawable.f5);

        int reasonableDuration = 750;
        mAnimation = new AnimationDrawable();
        mAnimation.addFrame(frame0, reasonableDuration);
        mAnimation.addFrame(frame1, reasonableDuration);
        mAnimation.addFrame(frame2, reasonableDuration);
        mAnimation.addFrame(frame3, reasonableDuration);
        mAnimation.addFrame(frame4, reasonableDuration);
        mAnimation.addFrame(frame5, reasonableDuration);

        img.setBackgroundDrawable(mAnimation);        
        strtbtn = (Button) findViewById(R.id.strtbtn);
        strtbtn.setOnClickListener(this);
        stpbtn = (Button) findViewById(R.id.stpbtn);
        stpbtn.setOnClickListener(this);
    }

    @Override
    public void onClick(View v) {

      if(v.getId()== R.id.strtbtn){

          mAnimation.start();
          mAnimation.setOneShot(false);
      }
      else
        mAnimation.stop();
    }  
}

布局主要......

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
<ImageView  
    android:id="@+id/iv"
    android:layout_width="400dp" 
    android:layout_height="250dp" />
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="horizontal"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
    <Button 
        android:layout_height="wrap_content" 
        android:id="@+id/strtbtn" 
        android:layout_width="wrap_content" 
        android:text="start"
        />    
    <Button 
        android:layout_height="wrap_content" 
        android:id="@+id/stpbtn" 
        android:layout_width="wrap_content" 
        android:text="stop"
        />    
</LinearLayout>
</LinearLayout>

以下是框架，或者您可以创建自己的...（放入名称为f0，f1，...的drawable）
