Question

我使用4.1.2

中的sherlock片段活动实现了sherlock主题

使用

机器人：主题= “@风格/ Theme.Sherlock.Light”

然后选项卡小部件显示（标签图标在这里显示正常）

enter image description here

这是好的，但是相同的代码在2.3.3中不起作用并显示标签（这里的标签图标不像上面那样）

enter image description here

如何在所有版本中使用图标获取相同的选项卡小部件。

这是我的xml代码

<TabHost xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@android:id/tabhost"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

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

        <TabWidget
            android:id="@android:id/tabs"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_weight="0"
            android:divider="@color/Columbia_Blue"
            android:baselineAligned="true"
            android:background="@android:color/darker_gray"
            android:orientation="horizontal" />

        <FrameLayout
            android:id="@android:id/tabcontent"
            android:layout_width="0dp"
            android:layout_height="0dp"
            android:layout_weight="0" />

        <android.support.v4.view.ViewPager
            android:id="@+id/pager"
            android:layout_width="match_parent"
            android:layout_height="0dp"
            android:layout_weight="1"
            android:background="@android:color/white" />
    </LinearLayout>

</TabHost>

这是java代码：

public class HomeFragment extends SherlockFragmentActivity {
    private TabHost mTabHost;
    private ViewPager mViewPager;
    private TabsAdapter mTabsAdapter;

    @Override

                R.drawable.blue);
        bitmap.setTileModeXY(TileMode.REPEAT, TileMode.REPEAT);
        getSupportActionBar().setBackgroundDrawable(bitmap);

        mTabHost = (TabHost) findViewById(android.R.id.tabhost);
        mTabHost.setup();

        mViewPager = (ViewPager) findViewById(R.id.pager);

        mTabsAdapter = new TabsAdapter(this, mTabHost, mViewPager);

        mTabsAdapter.addTab(
                mTabHost.newTabSpec("List").setIndicator("",
                        getResources().getDrawable(R.drawable.list_icon)),
                ListFragmentActivity.ListFragment.class, null);

        mTabsAdapter.addTab(

        if (savedInstanceState != null) {

        }
    }

    @Override

android:divider="@color/Columbia_Blue"
