1、res文件夹下创建anim目录

a、创建名称为motionright.xml的xml资源文件

<?xml version="1.0" encoding="utf-8"?>
    <animation-list xmlns:android="http://schemas.android.com/apk/res/android" >
    
        <item android:drawable="@drawable/pig1" android:duration="40" />
        <item android:drawable="@drawable/pig2" android:duration="40" />
    
    </animation-list>

b 、创建名称为motionleft .xml的xml资源文件

<?xml version="1.0" encoding="utf-8"?>
    <animation-list xmlns:android="http://schemas.android.com/apk/res/android" >
    
        <item android:drawable="@drawable/pig3" android:duration="40" />
        <item android:drawable="@drawable/pig4" android:duration="40" />
    
    </animation-list>

c 、创建名称为tramslateright .xml的xml资源文件

<?xml version="1.0" encoding="utf-8"?>
    <set xmlns:android="http://schemas.android.com/apk/res/android">
    	<translate 
    	    android:fromXDelta="0"
    	    android:toXDelta="850"
    	    android:fromYDelta="0"
    	    android:toYDelta="0"
    	    android:duration="3000">
    	</translate> 
    </set>

d、创建名称为tramslateleft.xml的xml资源文件

<?xml version="1.0" encoding="utf-8"?>
    <set xmlns:android="http://schemas.android.com/apk/res/android" >
    	<translate 
    	    android:fromXDelta="850"
    	    android:toXDelta="0"
    	    android:fromYDelta="0"
    	    android:toYDelta="0"
    	    android:duration="3000">
    	</translate> 
    </set>

2、布局文件

<?xml version="1.0" encoding="utf-8"?>
    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/linearLayout1"
    	android:background="@drawable/background"   
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:orientation="vertical" >
        <ImageView
            android:id="@+id/imageView1"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:background="@anim/motionright"
            android:layout_marginTop="280px"
            android:layout_marginLeft="30px"/>
    </LinearLayout>

3、onCreate方法中

public class MainActivity extends Activity {
    	private AnimationDrawable anim;
        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);
            final ImageView iv = (ImageView)findViewById(R.id.imageView1);//获取要应用动画效果的ImageView
            //获取向右奔跑的动画资源
            final Animation  translateright = AnimationUtils.loadAnimation(this, R.anim.translateright);
            //获取向左奔跑的动画资源
            final Animation  translateleft = AnimationUtils.loadAnimation(this, R.anim.translateleft);
            anim = (AnimationDrawable)iv.getBackground();//获取应用的帧动画
            LinearLayout ll = (LinearLayout)findViewById(R.id.linearLayout1);//获取线性布局管理器
            Toast.makeText(this, "触摸屏幕开始播放....", Toast.LENGTH_SHORT).show();
            ll.setOnTouchListener(new OnTouchListener() {
    			@Override
    			public boolean onTouch(View v, MotionEvent event) {
    				anim.start();//开始播放帧动画
    				iv.startAnimation(translateright);//播放香油泵奔跑的动画
    				return false;
    			}
    		});
            translateright.setAnimationListener(new AnimationListener() {
    			@Override
    			public void onAnimationStart(Animation animation) {
    			}
    			@Override
    			public void onAnimationRepeat(Animation animation) {
    			}
    			@Override
    			public void onAnimationEnd(Animation animation) {
    				iv.setBackgroundResource(R.anim.motionleft);//重新设置ImageView应用的帧动画
    				iv.startAnimation(translateleft);//播放向左奔跑的动画
    				anim = (AnimationDrawable)iv.getBackground();//获取应用的帧动画
    				anim.start();//开始播放帧动画
    			}
    		});
            translateleft.setAnimationListener(new AnimationListener() {
    			@Override
    			public void onAnimationStart(Animation animation) {
    			}
    			@Override
    			public void onAnimationRepeat(Animation animation) {
    			}
    			@Override
    			public void onAnimationEnd(Animation animation) {
    				iv.setBackgroundResource(R.anim.motionright);//重新设置ImageView应用的帧动画
    				iv.startAnimation(translateright);//播放向右奔跑的动画
    				anim = (AnimationDrawable)iv.getBackground();//获取应用的帧动画
    				anim.start();//开始播放帧动画
    			}
    		});
        }
    }
