Answer 1

set findViewById(R.id.lv_left_drawer); this view to FILL_PARENT or MATCH_PARENT in the xml. If it a linearlayout or a relativelayout with a listview inside, then set the background color of the main view, the root view to white

using

@android:color/white

Answer 2

The DrawerLayout height should be fill or match parent then you can change it programmatically

      mDrawerLayout.setBackgroundColor(Color.WHITE);

hope this will help.
