How To Determine A Long Touch On Android?

I am looking for a way for when a user long touches a mapview (lets say for 1000ms) that i can some how do a certain action. How would i go about judging how long a user long touc

Solution 1:

This is how do you normally create an onLongClickListener. Try this:

mapView.setOnLongClickListener(newOnLongClickListener() {

        @OverridepublicbooleanonLongClick(View arg0) {

            Toast.makeText(mapView.getContext(), "Hello 123", 2000);

            returnfalse;

        }
    });

Reference to your edit:

This might be the way to get what you want.

privatefinalHandlerhandler=newHandler();
privatefinalRunnablerunnable=newRunnable() {
publicvoidrun() {
     checkGlobalVariable();
}
};

// Other init stuff etc...@OverridepublicvoidonTouchEvent(MotionEvent event) {
if(event.getAction() == MotionEvent.ACTION_DOWN) {
    // Execute your Runnable after 1000 milliseconds = 1 second.
    handler.postDelayed(runnable, 1000);
    mBooleanIsPressed = true;
}

if(event.getAction() == MotionEvent.ACTION_UP) {
    if(mBooleanIsPressed) {
        mBooleanIsPressed = false;
        handler.removeCallbacks(runnable);
    }
}
}

And now you can check with checkGlobalVariable function:

if(mBooleanIsPressed == true)

This is how you can handle this case. Good luck.

Solution 2:

Your are probably looking for a normal long click? You will have to set your view to be long clickable by adding android:longClickable to your views xml, or by calling setLongClickable(true). Then you can add an OnLongClickListener to the view. I dont know of a way to determine exactly how long the long click is. But the default long click is the same as the google maps long click that you mentioned.

OnLongClickListener

Solution 3:

You can set up a longClickListener and a touchListener. Add a boolean class data member variable longClicked and set it to false initially. This is how you can set the longClickListener.

    view.setOnLongClickListener(newView.OnLongClickListener() {
        @OverridepublicbooleanonLongClick(View v) {
            longClicked = true;
            returnfalse;
        }
    });

For touchListener

    view.setOnTouchListener(newView.OnTouchListener() {
        @OverridepublicbooleanonTouch(View v, MotionEvent event) {
            if(longClicked){
                //Do whatever you want here!!
                longClicked = false;
            }
            returnfalse;
        }
    });

It will give you the same effect as google maps long click. Hope it helps.

Solution 4:

use System.currentTimeMillis() instead of ev.getEventTime();

Solution 5:

When MotionEvent.ACTION_UP, endTime will be set to ev.getEventTime(), this make setting endTime to zero when MotionEvent.ACTION_MOVE be not affect. Instead of setting endTime to zero, you should set startTime to ev.getEventTime()
