Android Onlongclicklistener Not Firing On Mapview

I just registered an OnLongClickListener on my my MapView on an Android app I'm currently writing. For some reason however the onLongClick event doesn't fire. Here's what I've writ

Solution 1:

I ran into the same problem and there is a simple solution to your problem actually; it's because you're using the wrong type of listener.

You should use the OnMapLongClickListener() object from the OnMapLongClickListener interface.

Hopefully everything should work properly :) Please tell me if it works.

Solution 2:

I just ran into this problem. I tried the solution above, but it doesn't quite work 100% in that we want the long press action to fire, even if the user is still holding a finger down.

This is how I implemented a solution, using a handler and a delayed task - As a side note, I used a similar type implementation, but in reverse, to hide/show zoom controls on touch/etc..

privateHandlermHandler=newHandler();

privatefinalRunnablemTask=newRunnable() {
    @Overridepublicvoidrun() {
        // your code here
    }
};

@OverridepublicbooleanonTouchEvent(MotionEvent ev) {
    if (ev.getAction() == MotionEvent.ACTION_DOWN) {
        // record the start time, start the timer
        mEventStartTime = ev.getEventTime();
        mHandler.postDelayed(mTask, LONG_PRESS_TIME);
    } elseif (ev.getAction() == MotionEvent.ACTION_UP) {
        // record the end time, dont show if not long enough
        mEventEndTime = ev.getEventTime();
        if (mEventEndTime - mEventStartTime < LONG_PRESS_TIME) {
            mHandler.removeCallbacks(mTask);        
        }
    } else {
        // moving, panning, etc .. up to you whether you want to// count this as a long press - reset timing to start from now
                    mEventStartTime = ev.getEventTime();
        mHandler.removeCallbacks(mTask);
                    mHandler.postDelayed(mTask, LONG_PRESS_TIME);
    }

    returnsuper.onTouchEvent(ev);
}

Solution 3:

In the mean time I found the "solution" (or workaround, call it as you like) by myself. The way I worked through this issue is by using a GestureDetector and forwarding all touch events to that object by implementing an according OnGestureListener interface.

I've posted some code on my blog if anyone is interested: http://juristr.com/blog/2009/12/mapview-doesnt-fire-onlongclick-event/

Don't ask me why this didn't work by hooking up the OnLongClickListener directly on the MapView. If someone has an explanation let me know :)

UPDATE: My previously suggested solution using a GestureDetector posed some drawbacks. So I updated the blog post on my site.

Solution 4:

In WebView framework code performLongClick() is used to handle long press event, this is how Android copy Text Feature is implemented in Browser, that is why onLongClick is not been fired.
