Question

I have an Activity that contains a ListView, and a TabHost.
Inside this TabHost I’m trying to add another Activity and it keeps crashing on me.
Any idea what’s causing this?

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

        <LinearLayout

            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>

Detail activity being added to tabhost
The xml file contains nothing, just a LinearLayout

public class DetailActivity extends RoboActivity {

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

Answer 1

1- I extended RoboTabActivity instead of RoboFragmentActivity

2- Changed my xml from android:id="@+id/tabHost" to android:id="@android:id/tabhost"

3- I added the activity to manifest file

4- Instead of injecting the Tabhost or use findById I used this.getTabHost()

Now the only question left is what if I need to use a DialogFragment? that usually requires the Activity to extend RoboFragmentActivity
