[android-developers] Cannot select rows from a ListView which contains Button controls

[John Gaby]

I have the following, very simple test program for using a ListView.
I create a ListView and set it as the content view.  I set a
ListAdapter which supplies the rows.  There are 30 rows, and each row
consists of a LinearLayout ViewGroup.  Into that ViewGroup, I place a
TextView and a Button.  When I run the program, I find that I cannot
select rows of the list.  I can, however, scroll the list and click
the button.

If I remove the button from the LinearLayout (so that it contains only
the TextView), then I am able to select rows of the list.  I would
like to be able to have buttons on my individual row views, and still
be able to select rows of the list.  I received a previous comment
saying that this was possible, but I am at a loss as to how to
accomplish it.

Can anyone give me a clue?

Thanks.

public class ListViewTest extends Activity implements ListAdapter
{
 int    m_count;
 DataSetObserver m_observer;

 public ListViewTest()
 {
  m_count  = 30;
  m_observer = null;
 }

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        ListView lv = new ListView(this);
        lv.setAdapter(this);
        lv.setChoiceMode(ListView.CHOICE_MODE_SINGLE);
        setContentView(lv);
   }

 @Override
 public boolean areAllItemsEnabled() {
  return true;
 }

 @Override
 public boolean isEnabled(int position) {
  return true;
 }

 @Override
 public int getCount()
 {
  return m_count;
 }

 @Override
 public Object getItem(int position) {
  return null;
 }

 @Override
 public long getItemId(int position) {
  return 0;
 }

 @Override
 public int getItemViewType(int position) {
  return 0;
 }

 @Override
 public View getView(int position, View convertView, ViewGroup
parent)
 {
  LinearLayout vg = new LinearLayout(this);

  TextView tv = new TextView(this);
  tv.setText("ListItem");

  Button bv = new Button(this);
  bv.setText("Button");

  vg.addView(tv);
  vg.addView(bv);

  return(vg);
 }

 @Override
 public int getViewTypeCount() {
  return 1;
 }

 @Override
 public boolean hasStableIds() {
  return false;
 }

 @Override
 public boolean isEmpty() {
  return false;
 }

 @Override
 public void registerDataSetObserver(DataSetObserver observer)
 {
  m_observer = observer;
 }

 @Override
 public void unregisterDataSetObserver(DataSetObserver observer) {

 }
}
