Android从左向右滑动

该解决方案解释了如何实现简单的手势监听器,并记录从左到右和从右到左的滑动.该示例中的相关代码位于GestureDetector onFling覆盖方法中.基本上,如果点1(e1)减去点2(e2)大于设定的最小滑动距离,那么你知道它从右到左.如果点2(e2)减去点1(e1)大于最小滑动距离则从左到右.

// right to left swipe
if(e1.getX() - e2.getX() > SWIPE_MIN_DISTANCE && Math.abs(veLocityX) > SWIPE_THRESHOLD_VELociTY) {
    Toast.makeText(SELEctFilterActivity.this,"Left Swipe",Toast.LENGTH_SHORT).show();
}  
// left to right swipe
else if (e2.getX() - e1.getX() > SWIPE_MIN_DISTANCE && Math.abs(veLocityX) > SWIPE_THRESHOLD_VELociTY) {
     Toast.makeText(SELEctFilterActivity.this,"Right Swipe",Toast.LENGTH_SHORT).show();
}
