在 Android 中捕获双击

Question

我正在使用 AndEngine 捕获 onSceneTouchEvent 事件。

我想要做的是不允许它捕获用户双击屏幕。

有没有办法检测双击或禁用它们？

谢谢

编辑：经过更多查看后，我认为这可能更适合您：

// in an onUpdate method

onUpdate(float secondsElapsed){

if(touched){
if(seconds > 2){
doSomething();
touched = false;
seconds = 0;
} else{
seconds += secondsElapsed;
}
}

}

根据上面的评论，我确信您也可以使用 SystemClock 来进行以下操作。

您可以添加延迟，类似于：

public boolean onTouch(View v, MotionEvent event) {
            // TODO Auto-generated method stub
            if(firstTap){
                thisTime = SystemClock.uptimeMillis();
                firstTap = false;
            }else{
                prevTime = thisTime;
                thisTime = SystemClock.uptimeMillis();

                //Check that thisTime is greater than prevTime
                //just incase system clock reset to zero
                if(thisTime > prevTime){

                    //Check if times are within our max delay
                    if((thisTime - prevTime) <= DOUBLE_CLICK_MAX_DELAY){

                        //We have detected a double tap!
                        Toast.makeText(DoubleTapActivity.this, "DOUBLE TAP DETECTED!!!", Toast.LENGTH_LONG).show();
                        //PUT YOUR LOGIC HERE!!!!

                    }else{
                        //Otherwise Reset firstTap
                        firstTap = true;
                    }
                }else{
                    firstTap = true;
                }
            }
            return false;
        }
