Android 游戏循环睡眠

我正在开发一款 Android 迷你游戏。我正在使用此代码进行游戏循环。

private RefreshHandler mRedrawHandler = new RefreshHandler();

class RefreshHandler extends Handler {

    @Override
    public void handleMessage(Message msg) {
        Panel.this.update();
        Panel.this.invalidate();
    }

    public void sleep(long delayMillis) {
        this.removeMessages(101);
        sendMessageDelayed(obtainMessage(101), delayMillis);
    }
};

public void update() {
    if (mMode == RUNNING) {
        ball.update(NR_PIX);

        for (int i=0; i<N; i++) {
            bords[i].update(NR_PIX);
        }

        Panel.lastBordHeight -= NR_PIX;

        if (mYBrickOffset == 0)
            mYBrickOffset = mYBrick;

        mYBrickOffset -= NR_PIX; 

        mRedrawHandler.sleep(mMoveDelay);
    }
}

RefreshHandler 类来自 SnakeView 类示例。

代码工作正常。我有一个“新游戏活动”按钮。当我第一次进入活动时，它就起作用了。但如果我退出游戏并再次进入，速度会更快，这是我不明白或不明白的事情。如果我退出游戏并使用“新游戏”按钮再次进入，速度会更快。

谁能帮我解决这个问题吗？

I am working on a mini game for Android. I am using this code for the game loop.

private RefreshHandler mRedrawHandler = new RefreshHandler();

class RefreshHandler extends Handler {

    @Override
    public void handleMessage(Message msg) {
        Panel.this.update();
        Panel.this.invalidate();
    }

    public void sleep(long delayMillis) {
        this.removeMessages(101);
        sendMessageDelayed(obtainMessage(101), delayMillis);
    }
};

public void update() {
    if (mMode == RUNNING) {
        ball.update(NR_PIX);

        for (int i=0; i<N; i++) {
            bords[i].update(NR_PIX);
        }

        Panel.lastBordHeight -= NR_PIX;

        if (mYBrickOffset == 0)
            mYBrickOffset = mYBrick;

        mYBrickOffset -= NR_PIX; 

        mRedrawHandler.sleep(mMoveDelay);
    }
}

The RefreshHandler class is from the SnakeView class example.

The code works ok. I have a Activity for a New Game button. When I first enter the Activity it's works. But if I exit the game and enter again the speed it's faster, thing that I don't wont or understand. If I exit the game and enter again using the New Game button the speed is faster even more.

Can anyone help me with this ?

我已经成功解决了 Activity 中覆盖 onPause 的问题。这是新代码：

class RefreshHandler extends Handler {
    Handler h = new Handler();
    Run run = new Run();

    class Run implements Runnable {

        @Override
        public void run() {
            // TODO Auto-generated method stub
            Panel.this.update();
            Panel.this.invalidate();
        }
    }

    public void sleep(long delayMillis) {
        h.postDelayed(run, delayMillis);
    }

    public void sleepCanceled() {
        h.removeCallbacks(run);
    }
};

I have managed to solve the problem overriding onPause in Activity. Here is the new code:

class RefreshHandler extends Handler {
    Handler h = new Handler();
    Run run = new Run();

    class Run implements Runnable {

        @Override
        public void run() {
            // TODO Auto-generated method stub
            Panel.this.update();
            Panel.this.invalidate();
        }
    }

    public void sleep(long delayMillis) {
        h.postDelayed(run, delayMillis);
    }

    public void sleepCanceled() {
        h.removeCallbacks(run);
    }
};
