Dear Sirs and Madams!

In my first Android app, I have an activity with ListView, which contens are not shown. At the app launch, I have a splash screen, which then switches to main activity, which should show listview with three string elements. Why string elements are not shown? Here is a code of CMainActivity's xml build:
Code:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">
    <ListView android:id="@+android:id/listview_mainscreen"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:drawSelectorOnTop="false"
    />
</LinearLayout>
Here is CMainActivity's java code:
Code:
/*

 * and open the template in the editor.

package com.oljedirekt.trgovko.main;
import android.app.ListActivity;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import com.oljedirekt.trgovko.R;

public class CActivityMainScreen extends ListActivity
{
    private static final String m_strLogTag="CActivityMainScreen";

    private static final String[] items={
                                            "Iskanje produktov",
                                            "Nakupovalna košarica",
                                            "O programu"
                                        };

    @Override
    public void onCreate(Bundle icicle)
    {
        try
        {
            super.onCreate(icicle);
            setContentView(R.layout.cactivitymainscreen);

            ListView mainScreenListView=(ListView)findViewById(R.id.listview_mainscreen);

            mainScreenListView.setAdapter(new ArrayAdapter<String>(this,
                                          R.layout.citemmainscreen,
                                          items));
        }
        catch(Exception ex)
        {
            String strClassName=ex.getClass().getName().toString();
            String strMessage=ex.getMessage().toString();

            Log.wtf(CActivityMainScreen.m_strLogTag,
                    strClassName+":"+
                    strMessage);

/*
            Log.wtf(CActivityMainScreen.m_strLogTag,
                    ex.getClass().getName()+":"+
                    ex.getMessage().toString());
*/
        }
        finally
        {
        }   // try-catch-finally
    }   // onCreate

    @Override
    public void onListItemClick(ListView parent,
                                View v,
                                int position,
                                long id)
    {
    }   // onListItemClick
}
Here is xml build of listview's row:
Code:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:orientation="horizontal"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent">
        <TextView android:id="@+id/item_mainscreen_text"
            android:gravity="center"
            android:textSize="22dip"
            android:textColor="#ffffff"
            android:textStyle="bold"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
        />
</LinearLayout>
And here is activity transition code (from SplashScreen to MainActivity):
Code:
                    try
                    {
                        Intent intent=new Intent(CActivitySplashScreen.this,
                                                 CActivityMainScreen.class);
                        startActivity(intent);
                    }
                    catch(Exception ex)
                    {
                        Log.wtf(CActivitySplashScreen.m_strLogTag,
                                ex.getClass().getName()+":"+
                                ex.getMessage().toString());
                    }
                    finally
                    {
                    }   // try-catch-finally
Now, why listview's items are not shown????

Sincerely,
Marko
