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) {
}
}
