    Hi,

    I have a problem with the listview in the tabwidget.
    My source is the following:

    main.xml:
    <?xml version="1.0" encoding="utf-8"?>
    <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">
    <LinearLayout android:eek:rientation="vertical"
    android:layout_width="fill_parent" android:layout_height="fill_parent"
    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">
    <ListView android:id="@+id/all_devices"
    android:layout_width="fill_parent" android:layout_height="fill_parent"
    android:layout_centerHorizontal="true"></ListView>
    <ListView android:id="@+id/fav_devices"
    android:layout_width="fill_parent" android:layout_height="fill_parent"
    android:layout_centerHorizontal="true">
    </ListView>
    </FrameLayout>
    </LinearLayout>
    </TabHost>

    main.java:
    package iUngi.iKey;

    import java.util.ArrayList;
    import java.util.Arrays;

    import android.app.TabActivity;
    import android.content.Intent;
    import android.content.res.Resources;
    import android.os.Bundle;
    import android.widget.ArrayAdapter;
    import android.widget.ListView;
    import android.widget.TabHost;

    public class iBlueKey extends TabActivity {
    /** Called when the activity is first created. */


    public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    Resources res = getResources(); // Resource object to get Drawables
    TabHost tabHost = getTabHost(); // The activity TabHost
    TabHost.TabSpec spec; // Resusable TabSpec for each tab
    Intent intent; // Reusable Intent for each tab

    // Create an Intent to launch an Activity for the tab (to be reused)
    intent = new Intent().setClass(this, ArtistsActivity.class);

    // Initialize a TabSpec for each tab and add it to the TabHost
    spec = tabHost.newTabSpec("all_devices").setIndicator("All visible devices",
    res.getDrawable(R.drawable.m_all))
    .setContent(intent);

    tabHost.addTab(spec);

    // Do the same for the other tabs
    intent = new Intent().setClass(this, AlbumsActivity.class);
    spec = tabHost.newTabSpec("fav_devices").setIndicator("Favorite devices",
    res.getDrawable(R.drawable.m_fav))
    .setContent(intent);
    tabHost.addTab(spec);

    tabHost.setCurrentTab(0);

    }
    }


    I tray to add a listview to the first tab, but I get a runtime error.

    package iUngi.iKey;

    import android.app.Activity;
    import android.os.Bundle;
    import android.widget.ArrayAdapter;
    import android.widget.ListView;
    import iUngi.iKey.R;

    public class AlbumsActivity extends Activity {
    static final String[] COUNTRIES = new String[] {
    "Afghanistan", "Albania", "Algeria", "American Samoa", "Andorra"};
    public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    // setContentView(R.layout.fav_list);

    ListView list = (ListView)findViewById(R.id.all_devices);
    ArrayAdapter adapter =
    new ArrayAdapter(this, R.layout.list_layout, COUNTRIES);
    list.setAdapter(adapter);

    registerForContextMenu(list);
    }

    }

    list_layout.xml:

    <?xml version="1.0" encoding="utf-8"?>
    <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="16sp" >
    </TextView>

    If you have any suggestion or idea please share with me.
    Thanks.
