Jelly Bean上的“垃圾邮件”导致应用程序崩溃,适用于Gingerbread

我正在写一个平台游戏,我在使用Jelly Bean的设备上遇到多点触控问题。我屏幕上有3个按钮 - 左箭头,右箭头和跳跃按钮。在我使用Gingerbread的手机上,我可以快速按下按钮,应用程序不会崩溃,但在我的朋友的手机上使用Jelly Bean,一旦他开始发送垃圾邮件按钮就会崩溃(我的意思是一次不止一个,所以我猜它是多点触控的问题) 。这是我处理触摸的代码:

public boolean onTouchEvent(MotionEvent event) {
    int pointerIndex = (event.getAction() & MotionEvent.ACTION_POINTER_ID_MASK) >> MotionEvent.ACTION_POINTER_ID_SHIFT;
    int pointerId = event.getPointerId(pointerIndex);

    if (event.getActionMasked() == MotionEvent.ACTION_DOWN || event.getActionMasked() == MotionEvent.ACTION_POINTER_DOWN) {
        if(currentState == GAME_RUNNING) {
            leftArrow.handleActionDown((int)event.getX(pointerId), (int)event.getY(pointerId), pointerId);
            if(leftArrow.isTouched() && leftArrow.getPointerId() == pointerId)
                hero.setDirectionLeft();
            rightArrow.handleActionDown((int)event.getX(pointerId), (int)event.getY(pointerId), pointerId);
            if(rightArrow.isTouched() && rightArrow.getPointerId() == pointerId)
                hero.setDirectionRight();
            jumpButton.handleActionDown((int)event.getX(pointerId), (int)event.getY(pointerId), pointerId);
            if(jumpButton.isTouched() && jumpButton.getPointerId() == pointerId) 
                jumped = true;
        }
        else
            activity.finish();
    }
    if (event.getActionMasked() == MotionEvent.ACTION_UP || event.getActionMasked() == MotionEvent.ACTION_POINTER_UP) {
        if(currentState == GAME_RUNNING) {
            if(leftArrow.isTouched() && leftArrow.getPointerId() == pointerId)
                leftArrow.setTouched(false);
            if(rightArrow.isTouched() && rightArrow.getPointerId() == pointerId)
                rightArrow.setTouched(false);
            if(jumpButton.isTouched() && jumpButton.getPointerId() == pointerId) {
                jumpButton.setTouched(false);
            }
        }
    }
    if (event.getActionMasked() == MotionEvent.ACTION_MOVE) {
        int pointerCount = event.getPointerCount();
        for(int i = 0; i < pointerCount; ++i)
        {
            pointerIndex = i;
            pointerId = event.getPointerId(pointerIndex);
            if(currentState == GAME_RUNNING) {  
                leftArrow.handleActionDown((int)event.getX(pointerId), (int)event.getY(pointerId), pointerId);
                if(leftArrow.isTouched() && leftArrow.getPointerId() == pointerId) {
                    if(rightArrow.isTouched() && rightArrow.getPointerId() == pointerId)
                        rightArrow.setTouched(false);
                    hero.setDirectionLeft();
                }
                rightArrow.handleActionDown((int)event.getX(pointerId), (int)event.getY(pointerId), pointerId);
                if(rightArrow.isTouched() && rightArrow.getPointerId() == pointerId) {
                    if(leftArrow.isTouched()  && leftArrow.getPointerId() == pointerId)
                        leftArrow.setTouched(false);
                    hero.setDirectionRight();
                }
            }
        }
    }
    return true;
}

也来自按钮类:

public boolean isTouched() {
    return touched;
}

public void setTouched(boolean touched) {
    this.touched = touched;
}

public int getPointerId() {
    return pointerId;
}

public void handleActionDown(int eventX, int eventY, int id) {
    if (eventX >= (x - (bitmap.getWidth()) / 2) && (eventX <= (x + (bitmap.getWidth()) / 2)))
        if (eventY >= (y - (bitmap.getWidth()) / 2) && (eventY <= (y + (bitmap.getWidth()) / 2))) {
            setTouched(true);
            pointerId = id;
        }
}

错误:

MotionEvent#getX()的参数是指针索引,而不是指针ID。这是您的错误来源。
