Android-將活動添加到TabHost？

Question

我有一個包含ListView和TabHost的Activity。 在此TabHost內，我試圖添加另一個Activity，但它一直崩潰。 知道是什么原因造成的嗎？

public class MainActivity extends RoboFragmentActivity {

    @InjectView(R.id.listView)
    private ListView listView;
    @InjectView(R.id.tabHost)
    private TabHost tabHost;
    @Inject
    IIntentProxy intentProxy;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main_activity);

        tabHost.setup();

        TabHost.TabSpec spec = tabHost.newTabSpec("tag");
        spec.setContent(intentProxy.getIntent(DetailActivity.class));
        spec.setIndicator("Title");

                // It crashes on line below
                // tabHost is not null, neither is spec
        tabHost.addTab(spec);
    }

}

。

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="horizontal"
    android:weightSum="100" >

    <TabHost
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/tabHost"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_weight="50" >

        <LinearLayout
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
            android:orientation="vertical"
            android:padding="5dp" >

            <TabWidget
                android:id="@android:id/tabs"
                android:layout_width="fill_parent"
                android:layout_height="wrap_content" >

                <FrameLayout
                    android:id="@android:id/tabcontent"
                    android:layout_width="fill_parent"
                    android:layout_height="fill_parent"
                    android:padding="5dp" >
                </FrameLayout>
            </TabWidget>
        </LinearLayout>
    </TabHost>

    <ListView
        android:id="@+id/listView"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_weight="50" >
    </ListView>

</LinearLayout>

將詳細信息活動添加到tabhost xml文件不包含任何內容，僅包含LinearLayout

public class DetailActivity extends RoboActivity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.detail_activity);
    }
}

Answer 1

你不能用

擴展活動

您必須使用

擴展ActivityGroup

該鏈接對此做了一些解釋：

Android異常：您是否忘記了調用“公共無效設置（LocalActivityManager activityGroup）”

Answer 2

1-我擴展了RoboTabActivity而不是RoboFragmentActivity

2-將我的xml從android:id="@+id/tabHost"更改為android:id="@android:id/tabhost"

3-我將活動添加到清單文件

4-不是注入Tabhost或使用findById，而是使用this.getTabHost this.getTabHost()

現在剩下的唯一問題是，如果我需要使用DialogFragment，該怎么辦？ 通常需要Activity擴展RoboFragmentActivity
