public class BaseNavigationDrawerActivity extends BaseActivity implements 



     // for getting Left Navigation drawerImages 

     @Override 
     protected void onCreate(Bundle savedInstanceState) { 
      super.onCreate(savedInstanceState); 
      setContentView(R.layout.activity_navigation_screen); 

      mContext = BaseNavigationDrawerActivity.this; 
      mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout); 
      mDrawersList = (ListView) findViewById(R.id.lv_left_drawer); 

      LayoutInflater inflater = this.getLayoutInflater(); 

      // adding listview header 
      View header = inflater.inflate(R.layout.leftnav_headerview, null); 
      mDrawersList.addHeaderView(header); 
      mProfileView = (ImageView) header.findViewById(R.id.img_profile); 
      mProfileUserName = (TextView) header.findViewById(R.id.tv_username); 
      // set a custom shadow that overlays the main content when the drawer 
      // opens 
      ShowLogoutOption(); 

      mDrawerLayout.setDrawerShadow(R.drawable.drawer_shadow, 
        GravityCompat.START); 

      mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout, 
        R.drawable.ic_apphistory_menu, R.string.drawer_open, 
        R.string.drawer_close) { 
       @Override 
       public void onDrawerClosed(View drawerView) { 
        supportInvalidateOptionsMenu(); 
       } 

       @Override 
       public void onDrawerOpened(View drawerView) { 
        supportInvalidateOptionsMenu(); 
       } 
      }; 

      mNavigationDrawerAdapter = new NavigationDrawerItemsAdapter(); 
      mDrawersList.setAdapter(mNavigationDrawerAdapter); 
      mDrawerLayout.setDrawerListener(mDrawerToggle); 
      mProfileUserName.setEnabled(false); 
      mDrawersList.setOnItemClickListener(new DrawerItemClickListener()); 
      mProfileView.setOnClickListener(this); 
      initActionBar("",false); 
     } 

     @Override 
     protected void onResume() { 
      super.onResume(); 

      mNavigationDrawerAdapter.notifyDataSetChanged(); 
     } 



     @Override 
     protected void onPostCreate(Bundle savedInstanceState) { 
      super.onPostCreate(savedInstanceState); 
      // Sync the toggle state after onRestoreInstanceState has occurred. 
      mDrawerToggle.syncState(); 
     } 

     @Override 
     public void onConfigurationChanged(Configuration newConfig) { 
      super.onConfigurationChanged(newConfig); 
      // Pass any configuration change to the drawer toggls 
      mDrawerToggle.onConfigurationChanged(newConfig); 
     } 

     private class DrawerItemClickListener implements OnItemClickListener { 
      @Override 
      public void onItemClick(AdapterView<?> parent, View v, int position, 
        long arg3) { 
       mDrawersList.setChoiceMode(ListView.CHOICE_MODE_SINGLE); 



      } 


     } 

     @Override 
     public boolean onCreateOptionsMenu(Menu menu) { 
      return super.onCreateOptionsMenu(menu); 
     } 

     @Override 
     public boolean onOptionsItemSelected(MenuItem item) { 
      if (mDrawerToggle.onOptionsItemSelected(item)) { 
       return true; 
      } 
      return super.onOptionsItemSelected(item); 
     } 

     protected void replaceFragment(Fragment fragment) { 
      FragmentManager fragmentManager = getSupportFragmentManager(); 
      fragmentManager.beginTransaction() 
        .replace(R.id.content_frame, fragment).commit(); 
     }

Answer 1

set findViewById(R.id.lv_left_drawer);此視圖爲xml中的FILL_PARENT或MATCH_PARENT。如果它的LinearLayout或一個ListView一個RelativeLayout的內部，然後設置使用

@android:color/white 

Answer 2

的DrawerLayout高度應填寫或匹配父，那麼你的主視圖的背景顏色，根以白色

可以編程方式更改它

 mDrawerLayout.setBackgroundColor(Color.WHITE); 

希望這會有所幫助。
