上文中在代码中设置了补间动画，在本文中将使用XML来定义补间动画，代码如下：

动画XML：

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" >

    <alpha
        android:duration="3000"
        android:fromAlpha="1"
        android:repeatCount="-1"
        android:repeatMode="reverse"
        android:toAlpha="0.3" />

    <rotate
        android:duration="3000"
        android:fromDegrees="0"
        android:pivotX="50%"
        android:pivotY="50%"
        android:repeatCount="-1"
        android:repeatMode="reverse"
        android:toDegrees="360" />

    <scale
        android:duration="3000"
        android:fromXScale="1"
        android:fromYScale="1"
        android:pivotX="50%"
        android:pivotY="50%"
        android:repeatCount="-1"
        android:repeatMode="reverse"
        android:toXScale="0"
        android:toYScale="0" />

    <translate
        android:duration="3000"
        android:fillAfter="true"
        android:fromXDelta="0"
        android:fromYDelta="0"
        android:toXDelta="300"
        android:toYDelta="300" />

</set>

Activity：

package com.lovo.testtween;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.animation.Animation;
import android.view.animation.AnimationUtils;
import android.widget.Button;
import android.widget.ImageView;

public class TestTweenActivity extends Activity {
	private ImageView imageView;

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.main);
		imageView = (ImageView) findViewById(R.id.main_iv);
		Button startBtn = (Button) findViewById(R.id.main_btn_start);
		startBtn.setOnClickListener(new OnClickListener() {

			@Override
			public void onClick(View v) {
				// 加载动画资源
				Animation animation = AnimationUtils.loadAnimation(
						TestTweenActivity.this,R.anim.test_tween_anim);
				// 启动动画
				imageView.startAnimation(animation);
			}
		});
		Button clearBtn = (Button) findViewById(R.id.main_btn_clear);
		clearBtn.setOnClickListener(new OnClickListener() {

			@Override
			public void onClick(View v) {
				// 清除动画效果
				imageView.clearAnimation();
			}
		});
	}

}

布局XML：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <Button
        android:id="@+id/main_btn_start"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="开始动画" />

    <Button
        android:id="@+id/main_btn_clear"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="清除动画" />

    <ImageView
        android:id="@+id/main_iv"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:background="@drawable/freedom1" />

</LinearLayout>
