I have a problem in my Android application. I have a Custom ListView Adapter, but when I launch the application the list does not show any item! 

My Code :

```
import android.app.Activity;
import android.os.Bundle;
import android.widget.ListView;

public class AccountContents extends Activity {
    private ListView ls1;
    String username = fourshared.username;
    String password = fourshared.password;
    private AccountItem[] rootContents;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        rootContents = fourshared.rootContents;
        CArrayAdapter adapter = new CArrayAdapter(AccountContents.this, rootContents);  
        setContentView(R.layout.main);
        ls1 = new ListView(AccountContents.this); 
        ls1.setAdapter(adapter);
    }
}

```
