Android-向TabHost添加活动？

我有一个包含ListView和TabHost的活动。 在这个TabHost中，我试图添加另一个活动，但它一直在崩溃。 知道是什么引起的吗

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);
    }

}

您不能使用

扩展活动

你必须使用

扩展活动组

这个链接解释了一点：

---

1-我扩展了

RoboTabActivity

而不是

RoboFragmentActivity

2-将我的xml从

android:id=“@+id/tabHost”

更改为

android:id=“@android:id/tabHost”

3-我将活动添加到清单文件

4-我使用了

this.getTabHost（）

---

现在唯一剩下的问题是如果我需要使用DialogFragment怎么办？这通常需要活动扩展RoboFragmentActivity

您是否在清单中声明了其他活动？@wasyl是的，我添加了它，现在我得到了一个新的异常。更新问题

public class DetailActivity extends RoboActivity {

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