Ok, so I wrote an ExpandableListView and subclassed BaseExpandableListAdapter...
Everything works fine except I cannot get the child views to take focus when clicked. If I use the trackball
everything works fine. But if I try to click on a child I get no feedback whatsoever.
I have tried setting android:focusable, android:focusableInTouchMode, and android:clickable (and I have also tried setting this via code) but I can't get anything to work. Any ideas?
Here is my Adapter code:
public class ExpandableAppAdapter extends BaseExpandableListAdapter
{
private PackageManager m_pkgMgr;
private Context m_context;
private List<ApplicationInfo> m_groups;
private List<List<ComponentName>> m_children;
public ExpandableAppAdapter(Context context, List<ApplicationInfo> groups, List<List<ComponentName>> children)
{
m_context = context;
m_pkgMgr = m_context.getPackageManager();
m_groups = groups;
m_children = children;
}
@Override
public Object getChild(int groupPos, int childPos)
{
return m_children.get(groupPos).get(childPos);
}
@Override
public long getChildId(int groupPos, int childPos)
{
return childPos;
}
@Override
public int getChildrenCount(int groupPos)
{
return m_children.get(groupPos).size();
}
@Override
public View getChildView(int groupPos, int childPos, boolean isLastChild, View convertView, ViewGroup parent)
{
if (convertView == null)
{
LayoutInflater inflater = LayoutInflater.from(m_context);
convertView = inflater.inflate(R.layout.expandable_app_child_row, null);
}
ComponentName child = (ComponentName)getChild(groupPos, childPos);
TextView txtView = (TextView)convertView.findViewById(R.id.item_app_pkg_name_id);
if (txtView != null)
txtView.setText(child.getPackageName());
txtView = (TextView)convertView.findViewById(R.id.item_app_class_name_id);
if (txtView != null)
txtView.setText(child.getClassName());
convertView.setFocusableInTouchMode(true);
return convertView;
}
@Override
public Object getGroup(int groupPos)
{
return m_groups.get(groupPos);
}
@Override
public int getGroupCount()
{
return m_groups.size();
}
@Override
public long getGroupId(int groupPos)
{
return groupPos;
}
@Override
public View getGroupView(int groupPos, boolean isExpanded, View convertView, ViewGroup parent)
{
if (convertView == null)
{
LayoutInflater inflater = LayoutInflater.from(m_context);
convertView = inflater.inflate(R.layout.expandable_app_group_row, null);
}
ApplicationInfo group = (ApplicationInfo)getGroup(groupPos);
ImageView imgView = (ImageView)convertView.findViewById(R.id.item_selection_icon_id);
if (imgView != null)
{
Drawable img = m_pkgMgr.getApplicationIcon(group);
imgView.setImageDrawable(img);
imgView.setMaxWidth(20);
imgView.setMaxHeight(20);
}
TextView txtView = (TextView)convertView.findViewById(R.id.item_app_name_id);
if (txtView != null)
txtView.setText(m_pkgMgr.getApplicationLabel(group));
return convertView;
}
@Override
public boolean hasStableIds()
{
return false;
}
@Override
public boolean isChildSelectable(int groupPos, int childPos)
{
return true;
}
}
Thanks in advance!
