How does Fragment Navigation Drawer open from right to left?
i am beginner in android and implementing my first app!.
i use a Fragment for Navigation Drawer in my app, and i want it to open from right to left. in the fragment tag of the main xml file i set android:layout_gravity="right" but when i run my app and touch the toggle button to open the navigation drawer, suddenly the app crashes! and i receive an error from logcat that is java.lang.IllegalArgumentException: No drawer view found with gravity LEFT . what should i do to solve this problem?
thanks so much.

For me adding the following property:
android:layoutDirection="rtl"
to the DrawerLayout and NavigationView Solved the problem

The problem is ActionBarDrawerToggle always expects the drawer to be on the side corresponding to Gravity.START. In most locales this is on the left side, hence it tries to open the drawer with Gravity.LEFT, but yours is on the other side so it throws an exception instead. Whether or not this seems like an intelligent design decision, it is what it is.
If you are following the Material Design guidelines, your drawer will cover the action bar when it opens (it might already be doing this). Specifically for this reason, I don't like using ActionBarDrawerToggle and don't find it particularly useful; the animation of the menu icon to an arrow is obscured by the drawer, and the other functionality is easy enough to implement directly in the activity. In your case, the animation might actually be useful if your drawer on the other side doesn't cover the icon, but then again you might not want the icon to animate at all anyway.
In your onCreate() method, all you need to do is
- Call
toolbar.setNavigationOnClickListener()(or set anOnClickListeneron a view in yourToolbar) and have this listener toggle the drawer usingdrawerLayout.openDrawer(Gravity.RIGHT)and the equivalentcloseDrawer()method. - Use
drawerLayout.addDrawerListener()to add a listener. When the drawer opens or closes, you can use this listener to change things like the toolbar's icon and/or its contentDescription (for accessibility), or to do anything else you like
