一、activity代碼
package com.liudan.activity;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.animation.AlphaAnimation;
import android.view.animation.Animation;
import android.view.animation.AnimationSet;
import android.view.animation.RotateAnimation;
import android.view.animation.ScaleAnimation;
import android.view.animation.TranslateAnimation;
import android.widget.Button;
import android.widget.ImageView;
public class AnimationActivity extends Activity {
private Button scale,rotate,alpha,translate;
private ImageView imageView;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
scale = (Button)findViewById(R.id.scale);
rotate = (Button)findViewById(R.id.rotate);
alpha = (Button)findViewById(R.id.alpha);
translate = (Button)findViewById(R.id.translate);
imageView = (ImageView)findViewById(R.id.imageView);
scale.setOnClickListener(new ScaleListener());

}
private class ScaleListener implements OnClickListener{

ScaleAnimation scaleAnimation = new ScaleAnimation(1,2f,1,2f,
Animation.RELATIVE_TO_SELF,0.5f, //相對於自身縮放到自身的哪個點。
Animation.RELATIVE_TO_SELF,0.5f);
scaleAnimation.setDuration(1000);
animationSet.addAnimation(scaleAnimation);
animationSet.setFillAfter(true); //讓其保持動畫結束時的狀態。
imageView.startAnimation(animationSet);
}
}
private class RotateListener implements OnClickListener{
@Override
public void onClick(View v) {
// TODO Auto-generated method stub

Animation.RELATIVE_TO_PARENT,1f,
Animation.RELATIVE_TO_PARENT,0f);

}
}
private class AlphaListener implements OnClickListener{
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
AnimationSet animationSet = new AnimationSet(true);
AlphaAnimation alphaAnimation = new AlphaAnimation(1,0);
alphaAnimation.setDuration(1000);

}
}

Animation.RELATIVE_TO_SELF,1f);
TranslateAnimation.setDuration(1000);
animationSet.addAnimation(TranslateAnimation);
imageView.startAnimation(animationSet);
}
}
}
二、 xml代碼
<?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">
<Button android:id="@+id/scale" android:layout_width="fill_parent"
android:layout_height="wrap_content" android:text="測試scale動畫效果" />
<Button android:id="@+id/rotate" android:layout_width="fill_parent"
android:layout_height="wrap_content" android:text="測試rotate動畫效果" />
<Button android:id="@+id/alpha" android:layout_width="fill_parent"
android:layout_height="wrap_content" android:text="測試alpha動畫效果" />
<Button android:id="@+id/translate" android:layout_width="fill_parent"
android:layout_height="wrap_content" android:text="測試translate動畫效果" />
<ImageView android:id="@+id/imageView" android:layout_width="wrap_content"
android:layout_height="wrap_content" android:src="@drawable/icon" />
</LinearLayout>
