推荐答案

使用 ACTION_UP 运动事件像这样编写您的代码

write your code like this with ACTION_UP motion event

 @Override
            public boolean onTouch(View view, MotionEvent motionEvent) {
                if (motionEvent.getAction() == MotionEvent.ACTION_UP) {
                    new DatePickerDialogFragment().show(getFragmentManager(),"DatePicker");                      
                }
                return false;
            }
