How to detect the touch event outside the navigation drawer
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);
}
