Çekmece KapatmaLayout istisna neden olur: LinearLayout, DrawerLayout'a dönüştürülemiyor

Question

Bir ListView içeren özel bir DrawerLayout kullanmaya çalışıyorum ancak çalışamıyorum. Bunu daha özel hale getirebilmek ve ListView üzerinde bir Görüntü ekleyebilmek için LinearLayout'un içeriğini kaydırmadan önce çalışmayı başarabiliyordum.

LineLayout'u taşırken CloseDrawer() öğesini kapatmaya çalıştığımda bu özel durum devam ediyor, ancak bu tür bir sorunla ilgili birden çok ileti görüyorum ancak bunların çoğu için düzeltme LinearLayout öğesini closeDrawer() işlevine iletmektir Ben zaten yaptım:

<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:tools="http://schemas.android.com/tools" 
    android:id="@+id/drawer_layout" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    tools:context=".MainActivity"> 

    <LinearLayout 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" 
     android:gravity="center" 
     android:orientation="vertical"> 

     <include layout="@layout/action_bar" /> 

     <FrameLayout 
      android:id="@+id/content_frame" 
      android:layout_width="match_parent" 
      android:layout_height="match_parent" /> 

     <LinearLayout 
      android:id="@+id/left_drawer_item" 
      android:layout_width="200dp" 
      android:layout_height="match_parent" 
      android:layout_gravity="start" 
      android:orientation="vertical"> 

      <ImageView 
       android:id="@+id/profilIcon" 
       android:layout_width="wrap_content" 
       android:layout_height="wrap_content" 
       android:src="@drawable/ic_people1blue2x" /> 

      <ListView 
       android:id="@+id/left_drawer_child" 
       android:layout_width="match_parent" 
       android:layout_height="match_parent" 
       android:choiceMode="singleChoice" 
       android:divider="@android:color/transparent" 
       android:dividerHeight="0dp" 
       android:background="#111" /> 

     </LinearLayout> 

    </LinearLayout> 

</android.support.v4.widget.DrawerLayout>

    setSupportActionBar(toolbar); 
    getSupportActionBar().setTitle(getResources().getString(R.string.app_name)); 
    getSupportActionBar().setDisplayHomeAsUpEnabled(true); 
    getSupportActionBar().setHomeButtonEnabled(true); 

    mPlanTitles = getResources().getStringArray(R.array.plan_list); 

    mDrawerLayout.setDrawerShadow(R.drawable.drawer_shadow, GravityCompat.START); 
    // set up the drawer's list view with items and click listener 
    ArrayList<String> myList = new ArrayList<>(); 
    myList.add("First Item"); 
    myList.add("Second Item"); 
    mDrawerListChild.setAdapter(new DrawerListAdapter(this, R.layout.drawer_layout_item, myList)); 
    mDrawerListChild.setOnItemClickListener(new DrawerItemClickListener()); 

    // enable ActionBar app icon to behave as action to toggle nav drawer 

    mDrawerToggle = new ActionBarDrawerToggle(
      this,     /* host Activity */ 
      mDrawerLayout,   /* DrawerLayout object */ 
      toolbar, /* nav drawer image to replace 'Up' caret */ 
      R.string.drawer_open, /* "open drawer" description for accessibility */ 
      R.string.drawer_close /* "close drawer" description for accessibility */ 
    ) { 
     public void onDrawerClosed(View view) { 
      //syncActionBarArrowState(); 
     } 

     public void onDrawerOpened(View drawerView) { 
      //mDrawerToggle.setDrawerIndicatorEnabled(true); 
     } 
    }; 
    getSupportFragmentManager().addOnBackStackChangedListener(mOnBackStackChangedListener); 
    mDrawerLayout.setDrawerListener(mDrawerToggle); 
    setSupportActionBar(toolbar); 
    user = getUser(); 

    if (savedInstanceState == null) { 
     selectItem(0); 
    } 

} 


private void selectItem(int position) { 
    BackHandledFragment fragment = new FragmentMobilePlan(); 
    setSelectedFragment(fragment); 

    FragmentTransaction ft = getSupportFragmentManager().beginTransaction(); 
    ft.setCustomAnimations(R.anim.pull_in_right, R.anim.push_out_left, R.anim.pull_in_left, R.anim.push_out_right); 
    ft.replace(R.id.content_frame, fragment) 
      .commit(); 

    // update selected item and title, then close the drawer 
    mDrawerListChild.setItemChecked(position, true); 
    setTitle(mPlanTitles[position]); 
    mDrawerLayout.closeDrawer(mDrawerLinear); 
}

Aynı soruna ters düşenler için bu istisnayı yaşıyordum çünkü CloseDrawer() için DrawerLayout'a geçen LinearLayout, XML'imde DrawerLayout öğesinin ikinci çocuğu değildi. Doğrudan çekmecenin içinde olmalıydı. [Android.support.v4.widget.DrawerLayout $ LayoutParams için ClassCastException android.widget.FrameLayout $ LayoutParams] (içinde
