具体的上一章已经介绍,直接上代码:
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;
public class GameView extends View
{
private AnimationDrawable frameAnimation = null;
Context mContext = null;
Drawable mBitAnimation = null;
public GameView(Context context)
{
super(context);
mContext = context;
frameAnimation = new AnimationDrawable();
//这里用一个循环了装载所有名字类似的资源
//如“a1.......15.png”的图片
//这个方法用处非常大
for (int i = 1; i <= 15; i++)
{
int id = getResources().getIdentifier("a" + i, "drawable", mContext.getPackageName());
mBitAnimation = getResources().getDrawable(id);
//参数mBitAnimation是该帧的图片
//参数500是该帧显示的时间,按毫秒计算
frameAnimation.addFrame(mBitAnimation, 500);
}
frameAnimation.setOneShot( false );
this.setBackgroundDrawable(frameAnimation);
}
public void onDraw(Canvas canvas)
{
super.onDraw(canvas);
}
public boolean onKeyUp(int keyCode, KeyEvent event)
{
switch ( keyCode )
{
case KeyEvent.KEYCODE_DPAD_UP:
frameAnimation.start();
break;
}
return true;
}
}
Xml实现:
res/anim/frameanimation.xml :
<?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/a2" android:duration="500" />
<item android:drawable="@drawable/a3" android:duration="500" />
<item android:drawable="@drawable/a4" android:duration="500" />
<item android:drawable="@drawable/a5" android:duration="500" />
<item android:drawable="@drawable/a6" android:duration="500" />
<item android:drawable="@drawable/a7" android:duration="500" />
<item android:drawable="@drawable/a8" android:duration="500" />

</animation-list>
