ListView in TabWidget

[iUngi]

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 androidrientation="vertical"
android:layout_width="fill_parent" android:layout_height="fill_parent"
androidadding="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"
androidadding="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"
androidadding="10dp"
android:textSize="16sp" >
</TextView>

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