No the standard button does not react to double clicks. See the documentation for the Button.DoubleClick event. It doesn’t react to double clicks because in Windows buttons always react to clicks and never to double clicks. Do you hate your users? Because you’ll be creating a button that acts differently than any other button in … Read more

You can use dispatchEvent to programatically trigger events: var event = new MouseEvent(‘dblclick’, { ‘view’: window, ‘bubbles’: true, ‘cancelable’: true }); document.getElementById(‘aa’).dispatchEvent(event); See the section “Triggering built-in events” on MDN.
int i = 0; btn.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { // TODO Auto-generated method stub i++; Handler handler = new Handler(); Runnable r = new Runnable() { @Override public void run() { i = 0; } }; if (i == 1) { //Single click handler.postDelayed(r, 250); } else if (i == 2) … Read more
Sometime it prints out ” and it’s a single click!” 2 times . It should print out ” and it’s a double click!”). That is normal. A double click only happens if you click twice within the specified time interval. So sometimes if you don’t click fast enough you will get two single clicks in … Read more
jQuery’s one() will fire the attached event handler once for each element bound, and then remove the event handler. If for some reason that doesn’t fulfill the requirements, one could also disable the button entirely after it has been clicked. $(document).ready(function () { $(“#submit”).one(‘click’, function (event) { event.preventDefault(); //do something $(this).prop(‘disabled’, true); }); }); It … Read more
Like Matt, I had a much better experience when I increased the timeout value slightly. Also, to mitigate the problem of single click firing twice (which I was unable to reproduce with the higher timer anyway), I added a line to the single click handler: el.onclick = function() { if (timer) clearTimeout(timer); timer = setTimeout(function() … Read more
This is a good question, and I actually don’t think it can be done easily. (Some discussion on this) If it is super duper important for you to have this functionality, you could hack it like so: function singleClick(e) { // do something, “this” will be the DOM element } function doubleClick(e) { // do … Read more
saving a last click time when clicking will prevent this problem. i.e. private long mLastClickTime = 0; … // inside onCreate or so: findViewById(R.id.button).setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { // mis-clicking prevention, using threshold of 1000 ms if (SystemClock.elapsedRealtime() – mLastClickTime < 1000){ return; } mLastClickTime = SystemClock.elapsedRealtime(); // do your magic … Read more
You can use the GestureDetector. See the following code: public class MyView extends View { GestureDetector gestureDetector; public MyView(Context context, AttributeSet attrs) { super(context, attrs); // creating new gesture detector gestureDetector = new GestureDetector(context, new GestureListener()); } // skipping measure calculation and drawing // delegate the event to the gesture detector @Override public boolean onTouchEvent(MotionEvent … Read more
