具體的上一章已經介紹,直接上代碼:
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();
//這裡用一個循環了裝載所有名字類似的資源
//如“a1.......15.png”的圖檔
//這個方法用處非常大
for (int i = 1; i <= 15; i++)
{
int id = getResources().getIdentifier("a" + i, "drawable", mContext.getPackageName());
mBitAnimation = getResources().getDrawable(id);
//參數mBitAnimation是該幀的圖檔
//參數500是該幀顯示的時間,按毫秒計算
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實作:
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/a1" android:duration="500" />
<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" />

<item android:drawable="@drawable/a15" android:duration="500" />
</animation-list>
