Disable onKeyDown for a ListView?

Question

How can I disable onKeyDown of a listView? I want the onKeyDown of the activity to handle the keyEvent and only the keyEvent. Thanks.

Its difficult to understand your question, can you please explain what do you want to achieve exactly? — Yaqub Ahmad, Dec 20 '11 at 12:14
When my listview is focused, when i press the dpad_down key, i don't want that the listview receive the event and change the selected item, i want to do other action. — Vervatovskis, Dec 20 '11 at 12:19

Use this class

public class CustomListView extends ListView {

public CustomListView(Context context, AttributeSet attrs) {
    super(context, attrs);
}

@Override
public boolean dispatchKeyEvent(KeyEvent event) {
    if ((KeyEvent.KEYCODE_DPAD_UP == event.getKeyCode() || KeyEvent.KEYCODE_DPAD_DOWN == event.getKeyCode())) {
        //handle key events here
    }
    return false;
}

}

If you are extending your listview from ListActivity then below will hep you.

onListItemClick:

@Override
protected void onListItemClick(ListView l, View v, int position, long id) {
    String item = (String) getListAdapter().getItem(position);
    Toast.makeText(this, item + " selected", Toast.LENGTH_LONG).show();
}

OnKeyDown:

@Override
    public boolean onKeyDown(int keyCode, KeyEvent event) {
    super.onKeyDown(keyCode, event);
        switch(keyCode)
        {
            case KeyEvent.KEYCODE_CAMERA:
             Toast.makeText(ListViewActivity.this, "Pressed Camera Button", Toast.LENGTH_SHORT).show();
                return true;
            case KeyEvent.KEYCODE_1:
             Toast.makeText(ListViewActivity.this, "Pressed 1", Toast.LENGTH_SHORT).show();
                return true;
            case KeyEvent.KEYCODE_HOME:
             Toast.makeText(ListViewActivity.this, "Pressed Home Button", Toast.LENGTH_SHORT).show();
                return true;

            case KeyEvent.KEYCODE_BACK:
             Toast.makeText(ListViewActivity.this, "Pressed Back Button", Toast.LENGTH_SHORT).show();
                finish();
                return true;
        }

        return false;
    }

Thank you ahmad, and if it is an activity not ListActivity. – Vervatovskis Dec 20 '11 at 13:56 — Vervatovskis, Dec 20 '11 at 13:56
