我的游戏有问题。每次玩家死亡时，都会出现一个屏幕，可以在其中按“再试一次？”。然而，当他按下这个按钮时，游戏崩溃了，android 说游戏被终止了。然后突然游戏重新开始。我无法弄清楚如何在重新启动之前解决游戏崩溃的问题。这是触摸的代码：

if (game_finish == 1) {
            if (event.getAction() == MotionEvent.ACTION_DOWN) {

                System.out.println("Trying again!!");
                activity.finish();

                Intent myIntent = new Intent(getContext(), Game.class);
                getContext().startActivity(myIntent);

            }
        }

完成所有后台工作的我的面板如下所示：

public abstract class Panel extends SurfaceView implements
        SurfaceHolder.Callback {

    public Panel(Context context) {
        super(context);

        getHolder().addCallback(this);

        runner = new RunnerThread(getHolder(), this);

        setFocusable(true);

        textPaint = new Paint();
        textPaint.setColor(Color.BLUE);
        textPaint.setTextSize(100);
        textPaint.setFakeBoldText(true);

        textPaint_1 = new Paint();
        textPaint_1.setColor(Color.BLUE);
        textPaint_1.setTextSize(50);
        textPaint_1.setFakeBoldText(true);

    }


    protected void update() {
    }


    protected void drawPrimitives(Canvas canvas) {

    }


    protected boolean processTouch(MotionEvent event) {
        return true;
    }


    public boolean addSprite(Sprite sprite) {

        synchronized (runner.getSurfaceHolder()) {
            return sprites.add(sprite);
        }
    }

    @Override
    public void onDraw(Canvas canvas) {


        canvas.drawColor(Color.BLACK);

        // draw all the panel's sprites
        for (Sprite s : sprites) {

            Rect destRect = new Rect(s.getLocation().x, s.getLocation().y,
                    s.getLocation().x + s.getSpriteWidth(), s.getLocation().y
                            + s.getSpriteHeight());

            canvas.save(); // save the position of the canvas
            if (s.getRotation() < 0 | s.getRotation() > 0) {
                canvas.rotate(s.getRotation(),
                        s.getLocation().x + (s.getSpriteWidth() / 2),
                        s.getLocation().y + (s.getSpriteHeight() / 2)); 
                canvas.drawBitmap(s.getGraphic(), s.getSourceRect(), destRect,
                        null); 
            }

            else {
                canvas.drawBitmap(s.getGraphic(), s.getSourceRect(), destRect,
                        null);
            }
            canvas.restore();

        }


        drawPrimitives(canvas);

        if (World.getGame_finish() == 1) {

            paint.setARGB(128, 255, 255, 255);

            rectF.set(0, 0, getMeasuredWidth(), getMeasuredHeight());

            paint.setARGB(128, 255, 255, 255);

            rectF.set(0, 0, getMeasuredWidth(), getMeasuredHeight());
            canvas.drawRect(rectF, paint);
            canvas.drawText("PAUSED", getWidth() / 3, getHeight() / 2,

确保像这样打电话给super.onPause()你Game Activity：

protected void onPause() {
    // your cleanup code
    super.onPause();
}

您的com.example.game.Game Activity. Android 平台要求您从超类（Activity在本例中）调用某些方法，以使应用程序正常运行。

此错误消息告诉您，您onPause()在活动中覆盖了方法，Game如下所示：

@Override
protected void onPause() {
    // your code
}

但是，该平台要求您从类中调用默认onPause()实现。Activity为此，请输入以下行：

super.onPause();

在Game.onPause()方法体的开头。所以，你最终会得到代码：

@Override
protected void onPause() {
    super.onPause();
    // your code - same as before
}

错误消息说：

02-21 12:40:56.143: E/AndroidRuntime(29399): android.app.SuperNotCalledException: Activity {com.example.game/com.example.game.Game} did not call through to super.onPause()

因此，转到您的com.example.game.Game Activity 并在您的onPause()中执行以下操作：

protected void onPause(){
   super.onPause();
// the rest of your code
}
