Finally I found the problem. I'm not sure whether it's a bug of
ArrayAdapter.....
Following is part of my code:
public class myActivity extends ListActivity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.lobbygamelist);
registerForContextMenu(getListView());
setListAdapter(new GameListAdapter ());
}
class GameListAdapter extends ArrayAdapter<String>{
.......
public View getView(int position, View convertView, ViewGroup parent)
{
View row = convertView;
if (row == null) {
LayoutInflater inflater = getLayoutInflater();
row = inflater.inflate(R.layout.gamerow,
parent, false);
}
ViewHolder holder=(ViewHolder)row.getTag();
if (holder==null) {
holder=new ViewHolder(row);
row.setTag(holder);
}
holder.watchNumber.setText("");
holder.playerWhite.setText("");
//////this call will disable context menu in
touch mode
this.notifyDataSetChanged();
}
}
1. When "notifyDataSetChanged" was called in "getView" of
"ArrayAdapter", context menu can not created in touch mode.
2. remove "notifyDataSetChanged" call, everything fine....
