Hi PlusMinus,

Syntax: [ Download ] [ Hide ]

Using java Syntax Highlighting

public class ScreenMdplOne extends ListActivity //implements OnItemSelectedListener 
 
{
 
    /** Called when the activity is first created. */
 
        //TextView t;
 
        //ListView l;
 
    @Override
 
    public void onCreate(Bundle icicle) {
 
        super.onCreate(icicle);
 
        TextView text_view;
 
        Button button;
 
        text_view=new TextView(this);
 
        text_view.setText("content overview area");
 
        button=new Button(this);
 
        button.setText("Select");
 
        IconTextAdapter ita=new IconTextAdapter(this);
 
        IconText it1 = new IconText("Audio",getResources().getDrawable(R.drawable.favicon));
 
        IconText it2 = new IconText("Video",getResources().getDrawable(R.drawable.bug));
 
        IconText it3 = new IconText("Streaming",getResources().getDrawable(R.drawable.locale));
 
        ita.addItem(it1);
 
        ita.addItem(it2);
 
        ita.addItem(it3);
 
        setListAdapter(ita); 
 
        this.setContentView(text_view);
 
    }
 
}

You can, but you are approaching it the wrong way!
You are now setting a textview as the only content in a ListActivity. Which is impossible since a listactivity requires a ListView with a special id.
If you want to use an activity extending ListActivity then at least add a ListView with the id "@android:id/list"

The easiest way doing this (in my opinion) is by creating your layout in XML and it must have at least the following attribute:

 <ListView android:id="@android:id/list"
 
    android:layout_width="fill_parent"
 
    android:layout_height="wrap_content"
 
    />

You can also create your textviews in here and read/edit them in Java by finding them with findViewById.

Hope this helps!

Yours sincerely,
