     getActivity().setTitle(planet); 
     return rootView; 
     } 
    } 
    } 

mój drawer_main.xml jak poniżej:

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

<!-- As the main content view, the view below consumes the entire 
    space available using match_parent in both dimensions. --> 
<FrameLayout 
    android:id="@+id/content_frame" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" /> 

<!-- android:layout_gravity="start" tells DrawerLayout to treat 
    this as a sliding drawer on the left side for left-to-right 
    languages and on the right side for right-to-left languages. 
    The drawer is given a fixed width in dp and extends the full height of 
    the container. A solid background is used for contrast 
    with the content view. --> 
<ListView 
    android:id="@+id/left_drawer" 
    android:layout_width="240dp" 
    android:layout_height="match_parent" 
    android:layout_gravity="start" 
    android:choiceMode="singleChoice" 
    android:divider="@android:color/transparent" 
    android:dividerHeight="0dp" 
    android:background="#111"/> 
    </android.support.v4.widget.DrawerLayout> 

Mój menifest.xml jest poniżej:

<?xml version="1.0" encoding="utf-8"?> 

<uses-sdk 
    android:minSdkVersion="8" 
    android:targetSdkVersion="16" /> 

<supports-screens 
    android:smallScreens="true" 
    android:normalScreens="true" 
    android:largeScreens="true" 
    android:xlargeScreens="true" 
    android:anyDensity="true" 
    /> 
<application 
    android:allowBackup="true" 
    android:icon="@drawable/ic_launcher" 
    android:label="@string/app_name" 
    android:theme="@style/AppTheme" >

      <category android:name="android.intent.category.LAUNCHER" /> 
     </intent-filter> 
    </activity> 
    </application> 

</manifest> 

użyłem Android Biblioteka wsparcie, które jest możliwe w 2,1 lub powyżej urządzenia według dokumentu actionbar ale w moim powyższym przykładzie, że pracuje nad urządzeniem 4.0 w 2.3 urządzenie to daje mi błąd jak poniżej:

jakikolwiek pomysł, jak mogę to rozwiązać?

Answer 1

Problem leży w pliku drawer_list_item.xml. Będziesz musiał usunąć te 2 linie:

android:background="?android:attr/activatedBackgroundIndicator" 
android:minHeight="?android:attr/listPreferredItemHeightSmall" 

Po usunięciu powinny działać. Oba te elementy wymagają późniejszych wersji api, aby działały poprawnie.

Answer 2

Utknąłem w tym samym problemie z tego samego samouczka po zastosowaniu wszystkich sugestii innych odpowiedzi, znalazłem (kilka chwil temu), że to także invalidateOptionsMenu();, który stwarza problem. Musisz użyć supportInvalidateOptionsMenu(); i działa w magiczny sposób.

mDrawerToggle = new ActionBarDrawerToggle(
     this,     /* host Activity */ 
     mDrawerLayout,   /* DrawerLayout object */ 
     R.drawable.ic_drawer, /* 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) { 
     getSupportActionBar().setTitle(mTitle); 
     supportInvalidateOptionsMenu(); // creates call to onPrepareOptionsMenu() 
    } 

    public void onDrawerOpened(View drawerView) { 
     getSupportActionBar().setTitle(mDrawerTitle); 
     supportInvalidateOptionsMenu(); // creates call to onPrepareOptionsMenu() 
    } 
    };
