Android屏幕保护程序示例代码

public class MyScreenSaver extends Service implements DreamService {
    private MyScreenSaverView mScreenSaverView;

    @Override
    public void onCreate() {
        super.onCreate();
        mScreenSaverView = new MyScreenSaverView(this);
        setContentView(mScreenSaverView);
    }

    @Override
    public void onDreamingStarted() {
        super.onDreamingStarted();
        mScreenSaverView.startAnimating();
    }

    @Override
    public void onDreamingStopped() {
        super.onDreamingStopped();
        mScreenSaverView.stopAnimating();
    }

    private class MyScreenSaverView extends View {
        private Animation mAnimation;

        public MyScreenSaverView(Context context) {
            super(context);
            mAnimation = AnimationUtils.loadAnimation(context, R.anim.my_animation);
        }

        public void startAnimating() {
            startAnimation(mAnimation);
        }

        public void stopAnimating() {
            clearAnimation();
        }

        @Override
        protected void onDraw(Canvas canvas) {
            // 在此处绘制屏幕保护内容
        }
