I have implemented Android Navigation drawer in my application. I am able to open/close the drawer when user touches the out side of navigation drawer. Can any one of you help me in detect the touch/click event when user touch/click out side the navigation drawer. I need to perform some functionality in that event. Please check the attached screenshot. Any help would be appriciated.

You have to handle the touch position in dispatchTouchEvent() method. Check more about touch hierarchy here

@Override    
public boolean dispatchTouchEvent(MotionEvent event) {
    if (event.getAction() == MotionEvent.ACTION_UP) {
        if (mDrawerLayout.isDrawerOpen(mRightDrawerListView)) {

            View content = findViewById(R.id.right_drawer);
            int[] contentLocation = new int[2];
            content.getLocationOnScreen(contentLocation);
            Rect rect = new Rect(contentLocation[0],
                contentLocation[1],
                contentLocation[0] + content.getWidth(),
                contentLocation[1] + content.getHeight());

            View toolbarView = findViewById(R.id.toolbar);
            int[] toolbarLocation = new int[2];
            toolbarView.getLocationOnScreen(toolbarLocation);
            Rect toolbarViewRect = new Rect(toolbarLocation[0],
                toolbarLocation[1],
                toolbarLocation[0] + toolbarView.getWidth(),
                toolbarLocation[1] + toolbarView.getHeight());


            if (!(rect.contains((int) event.getX(), (int) event.getY())) && !toolbarViewRect.contains((int) event.getX(), (int) event.getY())) {
                isOutSideClicked = true;
            } else {
                isOutSideClicked = false;
            }

        } else {
            return super.dispatchTouchEvent(event);
        }
    } else if (event.getAction() == MotionEvent.ACTION_DOWN && isOutSideClicked) {
        isOutSideClicked = false;
        return super.dispatchTouchEvent(event);
    } else if (event.getAction() == MotionEvent.ACTION_MOVE && isOutSideClicked) {
        return super.dispatchTouchEvent(event);
    }

    if (isOutSideClicked) {
        //make http call/db request
        Toast.makeText(this, "Hello..", Toast.LENGTH_SHORT).show();
    }
    return super.dispatchTouchEvent(event);
}

you may spend some time by checking this out.

DrawerLayout.DrawerListener

I hope it will help you as it helps me.

An example:

        DrawerLayout drawerLayout = activity.findViewById(R.id.drawer_layout);
        drawerLayout.addDrawerListener(new DrawerLayout.DrawerListener() {
            @Override
            public void onDrawerSlide(@NonNull View view, float v) {

            }

            @Override
            public void onDrawerOpened(@NonNull View view) {

            }

            @Override
            public void onDrawerClosed(@NonNull View view) {

            }

            @Override
            public void onDrawerStateChanged(int i) {

            }
        });

Good luck.

You can use onDrawerClosed

when you touch outside screen onDrawerClosed will call after close of Navigation Drawer

public void onDrawerClosed(View view) {
            super.onDrawerClosed(view);
            //do  here
}
