[android-developers] Re: Listening to Double Taps in MapView
I was able to make it work but now the navigation on the map is not
working.
any ideas?
thanks

Let's see. To get this going you need a few things. The class that
will receive your callback must implement the
GestureDetector.OnDoubleTapListener interface, for which it must
include implementations of onSingleTapConfirmed(), onDoubleTap(), and
onDoubleTapEvent(). In addition, I generally include as a member of
that class a GestureDetector object (I frequently include and use
OnGestureListener as well but I don't think that's relevant to this
discussion). Then, you must register your interest in the associated
callbacks, somewhere around the time of onCreate(), via some code like
this:
mGestureDetector = new GestureDetector(this);
mGestureDetector.setOnDoubleTapListener(this);
That should get it going. One other thing I did was override
dispatchTouchEvent(), at the end of which I call:
return mGestureDetector.onTouchEvent(event);
...but I'm not at all sure you *need* to do this to get double taps
rolling. I was using dispatchTouchEvent() for some other things.

other name. In your case, I found the following:
http://developer.android.com/reference/android/view/GestureDetector.O...
which suggests you need to write a method with the following
signature:
boolean onDoubleTap(MotionEvent e);

Hello,
I was able to listen to user touches or taps on the screen in a
MapView and trigger a dialog giving the user some feedback. I need to
implement the same concept but with double tap to trigger another
dialog.
I looked around and couldn't find much... I wrote this function:
public void setOnDoubleTapListener(MotionEvent event, MapView
mapView)
{
if (event.getAction() == MotionEvent.ACTION_UP) {
Dialog dialog1 = new
Dialog(HelloMapView2.this);
dialog1.setTitle(Current Location);
dialog1.setContentView(R.layout.custom);
TextView current_locode = (TextView)
dialog1.findViewById
(R.id.text);
current_locode.setText(Current
LoCode: );
dialog1.show();
}
but the compiler never goes through it when I double tap.
any ideas?
thanks
