[FIXED] Make fragment clickable when navigation drawer is opened

Issue

My problem is as follows: I lock the navigation drawer menu setDrawerLockMode(DrawerLayout.LOCK_MODE_LOCKED_OPEN) in the landscape mode of the tablet, but I need the fragment from the right to be active, so I can click it with navigation always opened. But I dont know how to do it. Please help.

Solution

There are a few things you need to do:

1. Disable the layout fading by setting a transparent color:

   drawer.setScrimColor(Color.TRANSPARENT);
   

2. Lock the drawer

   drawer.setDrawerLockMode(DrawerLayout.LOCK_MODE_LOCKED_OPEN);
   

3. Create a custom drawer class which allows clicking through when in locked mode:

   public class CustomDrawer extends DrawerLayout {
   
       public CustomDrawer(Context context) {
           super(context);
       }
   
       public CustomDrawer(Context context, AttributeSet attrs) {
           super(context, attrs);
       }
   
       public CustomDrawer(Context context, AttributeSet attrs, int defStyle) {
           super(context, attrs, defStyle);
       }
   
       @Override
       public boolean onInterceptTouchEvent(MotionEvent ev) {
           View drawer = getChildAt(1);
   
           if (getDrawerLockMode(drawer) == LOCK_MODE_LOCKED_OPEN && ev.getRawX() > drawer.getWidth()) {
               return false;
           } else {
               return super.onInterceptTouchEvent(ev);
           }
       }
   
   }
   

4. Use this class in xml:

   <com.example.myapplication.CustomDrawer
       xmlns:android="http://schemas.android.com/apk/res/android"
       android:layout_width="match_parent"
       android:layout_height="match_parent">
   
       <FrameLayout
           android:layout_width="match_parent"
           android:layout_height="match_parent">
           <!-- The main content view -->
       </FrameLayout>
       <ListView android:layout_width="100dp"
                 android:layout_height="match_parent"
                 android:layout_gravity="start"
                 android:background="#111"/>
   </com.example.myapplication.CustomDrawer>
