Android - Element with Touch and Click events

Question

I'm having problems trying to make an element respond differently when there is action like "click" or type "touch". When I click on the element (is a simple listener, not worth paste the code), it performs the action perfectly, but completely ignores the action of touch. That way I could associate the element to distinguish the two events?

Should I apply the listener to the children of the view that the action is executed?

Thanks.

Edit

Resolved!

Added a check on the use of the touch event before calling it.

@Override
public boolean dispatchTouchEvent(MotionEvent event) {
    super.dispatchTouchEvent(event);
    if (this.onTouchEvent(event))
        return this.onTouchEvent(event);
    else
        return false;
}

There is a `setOnTouchListener` for most Views. Have you tried that? — Simon Forsberg, Sep 30 '13 at 13:30
Yes, I tried to do it. But it ignored the touch event too and only the click event was listened. — Danilo, Sep 30 '13 at 13:45
Make sure that you return true from the onTouch method, otherwise you only get one event for ACTION_DOWN. — Simon Forsberg, Sep 30 '13 at 13:58
The program is still ignoring the event "touch". The method is performed by dragging any corner of the screen, unless the button with the click event... :/ — Danilo, Sep 30 '13 at 17:17

You can refer this thread for help, or use the answer straight away. Good luck =)

@Override
public boolean onTouchEvent(MotionEvent ev) {
    if (ev.getAction() == MotionEvent.ACTION_DOWN) {
        // record the start time, start the timer
        mEventStartTime = ev.getEventTime();
        mHandler.postDelayed(mTask, LONG_PRESS_TIME);
    } else if (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);
    }

    return super.onTouchEvent(ev);
}

I understand your code. But the program don't execute the method when I click on the buttons (with OnClickListener). — Danilo, Sep 30 '13 at 17:20
can you post the whole class? I suspect your listener is set on the class rather than the button — crazyPixel, Sep 30 '13 at 19:15
