Android Animation Frame动画

1.java代码实现：

package com.Aina.Android;

import android.content.Context;
import android.graphics.Canvas;
import android.graphics.drawable.AnimationDrawable;
import android.graphics.drawable.Drawable;
import android.view.KeyEvent;
import android.view.View;
import android.widget.ImageView;

 */
public class GameView extends View {

	private AnimationDrawable mAnimationDrawable = null;
	private Context mContext = null;
	private Drawable mDrawable = null;

	public GameView(Context context) {
		super(context);
		this.mContext = context;

		mAnimationDrawable = new AnimationDrawable();
		for (int i = 1; i <= 15; i++) {
			int id = this.getResources().getIdentifier("a" + i, "drawable",
					mContext.getPackageName());
			mDrawable = this.getResources().getDrawable(id);
			mAnimationDrawable.addFrame(mDrawable, 100);// 为动画添加一帧.时间为毫秒
		}
		mAnimationDrawable.setOneShot(false);// 设置播放模式是否循环，false循环，true不循环.

//		ImageView iv = new ImageView(mContext);
//		iv.setBackgroundResource(R.anim.frame);
//		mAnimationDrawable = (AnimationDrawable) iv.getBackground();		
		this.setBackgroundDrawable(mAnimationDrawable);// 显示动画.

	}

	@Override
	protected void onDraw(Canvas canvas) {
		super.onDraw(canvas);
	}
	public boolean onKeyDown(int keyCode, KeyEvent event) {
		if(keyCode==KeyEvent.KEYCODE_1){
			mAnimationDrawable.start();//启动动画.
		}
		return super.onKeyDown(keyCode, event);
	}
}

package com.Aina.Android;

import android.app.Activity;
import android.os.Bundle;
import android.view.KeyEvent;

public class Test_Frame extends Activity {
    /** Called when the activity is first created. */
	private GameView gv = null;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        gv = new GameView(this);
        setContentView(gv);
    }
	@Override
	public boolean onKeyDown(int keyCode, KeyEvent event) {
		return gv.onKeyDown(keyCode, event);
	}

}

2.xml布局文件实现:

<?xml version="1.0" encoding="utf-8"?>
<animation-list
	xmlns:android="http://schemas.android.com/apk/res/android"
	android:oneshot="false">
	<item android:drawable="@drawable/a1" android:duration="100" />
	<item android:drawable="@drawable/a2" android:duration="100" />
	<item android:drawable="@drawable/a3" android:duration="100" />
	<item android:drawable="@drawable/a4" android:duration="100" />
	<item android:drawable="@drawable/a5" android:duration="100" />
	<item android:drawable="@drawable/a6" android:duration="100" />
	<item android:drawable="@drawable/a7" android:duration="100" />
	<item android:drawable="@drawable/a8" android:duration="100" />
	<item android:drawable="@drawable/a9" android:duration="100" />
	<item android:drawable="@drawable/a10" android:duration="100" />
	<item android:drawable="@drawable/a11" android:duration="100" />
	<item android:drawable="@drawable/a12" android:duration="100" />
	<item android:drawable="@drawable/a13" android:duration="100" />
	<item android:drawable="@drawable/a14" android:duration="100" />
	<item android:drawable="@drawable/a15" android:duration="100" />
</animation-list>

package com.Aina.Android;

import android.graphics.Canvas;
import android.graphics.drawable.AnimationDrawable;
import android.graphics.drawable.Drawable;
import android.view.KeyEvent;
import android.view.View;
