每次点击往前100或往后100.

    
package com.ql.app;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;

public class App extends Activity {

	private ImageView iv;
	private int count;
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        
        iv = (ImageView)findViewById(R.id.iv);

简单循环动画的实现：

    
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" >
	<alpha
		android:interpolator="@android:anim/linear_interpolator" 
		android:fromAlpha="1.0"
		android:toAlpha="0.1"
		android:duration="2000"
		android:repeatCount="infinite"
		android:repeatMode="reverse"
		/>
</set>
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" android:interpolator="@android:anim/linear_interpolator">
	<translate 
	android:fromXDelta="0" 
	android:toXDelta="100%" 
	android:duration="2000"
	android:repeatCount="infinite"
	android:repeatMode="reverse"
	/>
</set>
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
	<scale 
	    android:fromXScale="1.0" 
	    android:toXScale="2.0"
		android:fromYScale="1.0" 
		android:toYScale="2.0" 
		android:pivotX="50%"
		android:pivotY="50%" 
		android:duration="2000" 
		android:repeatCount="infinite"
		android:repeatMode="reverse"
		android:interpolator="@android:anim/linear_interpolator" 
		/>
</set>

  

使用：

    
import android.app.Activity;
import android.os.Bundle;
import android.view.animation.Animation;
import android.view.animation.AnimationUtils;
import android.widget.ImageView;
import android.widget.TextView;

public class App extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        Animation alpha = AnimationUtils.loadAnimation(this, R.anim.anim_alpha);
        Animation translate = AnimationUtils.loadAnimation(this, R.anim.anim_translate);
        Animation scale = AnimationUtils.loadAnimation(this, R.anim.anim_scale);
        
        TextView tv=(TextView)findViewById(R.id.tv);
        tv.startAnimation(alpha);
        ImageView iv0=(ImageView)findViewById(R.id.iv0);
        ImageView iv1=(ImageView)findViewById(R.id.iv1);
        ImageView iv2=(ImageView)findViewById(R.id.iv2);
        iv0.startAnimation(alpha);
        iv1.startAnimation(translate);
        iv2.startAnimation(scale);
        
    }
}
