如何在android中检测按钮的时间按下持续时间？

Question

I want to detect time press duration of button by using setOnTouchListener with onTouch method

How I can do this ?

Answer 1

you can do it using onTouchListener

long FirstTouchTime ;
long duration ; 

public boolean onTouchEvent(MotionEvent event) {

    if (event.getAction() == MotionEvent.ACTION_DOWN) 
        FirstTouchTime = System.currentTimeMillis();    

    else if (event.getAction() == MotionEvent.ACTION_UP) {
        duration = System.currentTimeMillis(); - FirstTouchTime ;
        //duration value in millisecond 
    }
}

Answer 2

Maybe something like this :

long mLastClickTime;

findViewById(R.id.button).setOnTouchListener(new OnTouchListener() {
      @Override
      public void onTouch(View v, MotionEvent event) {
         if (event.getAction() == MotionEvent.ACTION_DOWN) 
            mLastClickTime = SystemClock.elapsedRealtime();

         else if (event.getAction() == MotionEvent.ACTION_UP) {
            long duration = SystemClock.elapsedRealtime() - mLastClickTime;
            // using threshold of 1000 ms
            if (duration > 1000) {
               // do your magic here
            }
         }
      }    
});
