Android Question

NavDrawer is not giving touches to other views

I want to create a drawer activity which contains a image. Now I want that the parent of image view, i.e. content_main2, which is relative layout, should listen to touch events like swipe and fling. but it is only receiving touch down.

My main activity is a Nav Drawer Activity.

content_main2.setOnTouchListener(new View.OnTouchListener() {

Answer

Just added,
android:focusableInTouchMode="true"
android:focusable="true"
android:clickable="true"

in content_main2 (RelativeLayout).
Everything is working now.
