unable to add views in TabHost by IDs, crashing
<p>I've created a TabHost example with 1 tab which is running fine. I'm adding views in tabs with <strong>TabContentFactory</strong> using <em>TabSpec.setContent(TabHost.TabContentFactory contentFactory)</em></p>

<p>But as soon as I try to add tabs by views in tabs using <strong>View/Resource IDs</strong> using <em>TabSpec.setContent(int viewId)</em> my app crashes. The code is as follows:</p>

<pre><code>public class MainAct extends TabActivity implements TabContentFactory{
    protected Resources res;
    protected ListView listView;
    protected LayoutInflater inflater;

    @Override
    public void onCreate(Bundle savedInstanceState) {
    /*init*/
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        res = getResources();
        listView = new ListView(this);

    /*prepare tabs*/
        TabHost tabHost = getTabHost();
        TabSpec spec;

        spec = tabHost.newTabSpec(res.getString(R.string.label_project));
        spec.setIndicator(res.getString(R.string.label_project));
        spec.setContent(this); // &lt;&lt; this works perfect
        //spec.setContent(R.id.list_item); // &lt;&lt; CRASHES
        //spec.setContent(R.id.list_item2); // &lt;&lt; CRASHES
        tabHost.addTab(spec);
    }

    @Override
    public View createTabContent(String tag) {
        return listView;
    }
}
</code></pre>

<p>My XML files are as follows</p>

<pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
&lt;TextView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:padding="10dp"
    android:textSize="22sp"
    android:id="@+id/list_item"&gt;
&lt;/TextView&gt;
</code></pre>

<p>and</p>

<pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
&lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
     android:id="@+id/list_item2"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"&gt;
    &lt;TextView android:id="@+id/TextView01"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="list_item2"&gt;
    &lt;/TextView&gt;
&lt;/LinearLayout&gt;
</code></pre>

<p>Both of them defines IDs properly, yet they crash. I've already gone through following online tutorials:</p>

<p><a href="http://android-pro.blogspot.com/2010/08/tabbed-applications-in-android.html" rel="nofollow">http://android-pro.blogspot.com/2010/08/tabbed-applications-in-android.html</a></p>

<p><a href="http://www.codeproject.com/KB/android/AndroidTabs.aspx" rel="nofollow">http://www.codeproject.com/KB/android/AndroidTabs.aspx</a></p>

<p><a href="http://www.androidpeople.com/android-custom-listview-tutorial-example/" rel="nofollow">http://www.androidpeople.com/android-custom-listview-tutorial-example/</a></p>

<p>All of them describes how to add views in tabs using IDs, but none works for me.</p>

<p><strong>All I want to do is to define a view in a layout file and add it inside my tab using IDs. Please help.</strong> </p>
