    text
    copied!<p>I'm working on upgrading an Android application (1.6 compatibility) which uses a <code>TabHost</code> to show 3 different tabs with nested activities.</p> <p>At the time I used the <code>ActivityGroup</code> trick to show nested activities in a tab but I'm very unhappy with this method since it's a real pain to handle some features.</p> <p>I heard about the Fragments API compatibility package for 1.6 and a <code>Fragment</code> looks perfect for what I want to do (show nested views / features within a tab with transition effects and stuff) but I can't make it work with a <code>TabHost</code> (It was meant to work with an <code>Action Bar</code> but it's not available in the compatibility package).</p> <p>Did any of you guys found a way to create such a structure in your applications?</p> <p>My error here is :</p> <blockquote> <pre><code>ERROR/AndroidRuntime(955): Caused by: java.lang.RuntimeException: Unable </code></pre> <p>to start activity ComponentInfo{com.XXX}: java.lang.IllegalArgumentException: No view found for id 0x1020011 for fragment MyFragment</p> </blockquote> <p><strong>CODE</strong></p> <p><strong>main.xml</strong></p> <p></p> <pre><code>&lt;TabHost xmlns:android="http://schemas.android.com/apk/res/android" android:id="@android:id/tabhost" android:layout_width="fill_parent" android:layout_height="fill_parent"&gt; &lt;LinearLayout android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent"&gt; &lt;FrameLayout android:id="@android:id/tabcontent" android:layout_width="fill_parent" android:layout_height="wrap_content" android:padding="5dp" android:layout_weight="1" /&gt; &lt;TabWidget android:id="@android:id/tabs" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_weight="0" /&gt; &lt;/LinearLayout&gt; &lt;/TabHost&gt; </code></pre> <p><strong>MainActivity.java</strong></p> <pre><code>public class MainActivity extends TabActivity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); Resources res = getResources(); final TabHost tabs = getTabHost(); TabHost.TabSpec spec; Intent i; i = new Intent(this, MyActivity.class); spec = tabs.newTabSpec("MyActivity").setIndicator("MyActivity",res.getDrawable(R.drawable.tab)).setContent(i); tabs.addTab(spec); } } </code></pre> <p><strong>MyActivity.class</strong></p> <pre><code>public class MyActivity extends FragmentActivity { private static String TAG = "MyActivity"; private static FragmentManager fragmentManager; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); fragmentManager = getSupportFragmentManager(); FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction(); ListeResultatFragment fragment = MyFragment.newInstance(); fragmentTransaction.add(android.R.id.tabcontent, fragment, "MyFragment"); fragmentTransaction.commit(); } } </code></pre> <p><strong>MyFragment.java</strong></p> <pre><code>public class MyFragment extends Fragment { public static MyFragment newInstance() { MyFragment instance = new MyFragment(); return instance; } @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { return inflater.inflate(R.layout.fragment, container, false); } } </code></pre>
