ScrollView is catching touch event for google map

Question

I have a horizontal scroll view that contains a hierarchy of viewgroups and then finally a google map. My problem is that the HSV is catching the left-right drag that's meant for the map. I've tried

 hsv.requestDisallowInterceptTouchEvent(true);

and even

 mapView.getParent().requestDisallowInterceptTouchEvent(true);

but to no avail. Is there anything I'm doing wrong here? Or can you suggest another solution?

I think this should have been my original question: How do I implement the solution posted here Mapview inside a ScrollView. Specifically, where do I put the code?

It seems you on the right way, but you should call requestDisallowInterceptTouchEvent(true) method on every touch event (see docs). Try this solution

Updated:

Try this out:

final HorizontalScrollView hsv = ... final MapView mapView = ... mapView.setOnTouchListener(new OnTouchListener() { @Override public boolean onTouch(View v, MotionEvent event) { switch (event.getAction()) { case MotionEvent.ACTION_MOVE: hsv.requestDisallowInterceptTouchEvent(true); break; case MotionEvent.ACTION_UP: case MotionEvent.ACTION_CANCEL: hsv.requestDisallowInterceptTouchEvent(false); break; } return mapView.onTouchEvent(event); } });

Can you help me out a bit more, please? Another problem I have is that I don't know where in the project I should put the code. I've read so many solutions to this but I really don't know where to put the code I've seen.

You have to create custom MapView. Follow the code snippet provided below

public class AppMapView extends MapView { public AppMapView(Context context, AttributeSet attrs) { super(context, attrs); } @Override public boolean dispatchTouchEvent(MotionEvent ev) { switch (ev.getAction()) { case MotionEvent.ACTION_UP: System.out.println("unlocked"); this.getParent().requestDisallowInterceptTouchEvent(false); break; case MotionEvent.ACTION_DOWN: System.out.println("locked"); this.getParent().requestDisallowInterceptTouchEvent(true); break; } return super.dispatchTouchEvent(ev); } }

In XML follow code below:

<com.tech.linez.brixlanepassenger.custom_views.AppMapView android:id="@+id/map_ride_route" android:layout_width="match_parent" android:layout_height="220dp" android:layout_margin="10dp"/>

try to override the onTouch of the map and always return true from it.
