DrawerLayout không làm việc trong 2.3 Device

Xin chào bạn bè tôi thực hiện một Demo Application cho DrawerLayout trong Tất cả các thiết bị Android

MainClass như sau:

     return rootView; 
     } 
    } 
    } 

drawer_main.xml tôi như dưới đây:

<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> 

My menifest.xml của tôi như sau

<?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" > 
    <activity 
     android:name="com.example.appcompactdemo.MainActivity"

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

</manifest> 

tôi đã sử dụng Thư viện hỗ trợ Android đó là khả thi trong 2.1 hoặc cao hơn thiết bị theo tài liệu actionbar nhưng trong ví dụ trên của tôi nó đang làm việc trên 4,0 thiết bị trong 2.3 thiết bị nó mang lại cho tôi lỗi như như dưới đây:

bất kỳ ý tưởng nào để tôi có thể giải quyết nó?

Answer 1

Sự cố nằm trong tệp drawer_list_item.xml. Bạn sẽ cần phải xóa 2 dòng này:

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

Khi những thứ đó được xóa, nó sẽ hoạt động. Cả hai mục này đều cần các phiên bản api mới hơn để hoạt động chính xác.

Answer 2

Bị mắc kẹt trong cùng một vấn đề từ cùng một hướng dẫn sau khi áp dụng tất cả các đề xuất của các câu trả lời khác, tôi đã tìm thấy (một vài giây trước) rằng đó là invalidateOptionsMenu(); quá gây ra sự cố. Bạn đã sử dụng supportInvalidateOptionsMenu(); và nó hoạt động một cách kỳ diệu.

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() 
    } 
    };
