Hi I'm developing an application that will require a Dialog Window, using a listview to select an item from this list.
The problem is I have two possibilities to implement, the easier (I think) is
using the AlertDialog.Builder, but the problem is here is my code, when the
button is pressed:
Context mContext = getApplicationContext();
LayoutInflater inflater = (LayoutInflater)
mContext.getSystemService(LAYOUT_INFLATER_SERVICE);
View _dialog_layout = inflater.inflate(R.layout.source, (ViewGroup)
findViewById(R.layout.shelf));
ListView _mslv = (ListView) _dialog_layout.findViewById(R.id.list);
_ms_manager = new MyCustomManager();
_ms_adapter = new MyCustomSourceAdapter(mContext, R.layout.row, new
ArrayList<MyCustomSourceItem>());
List< MyCustomSourceItem > _msList = _ms_manager.getSources();
for(MyCustomSourceItem _msItem : _msList) {
_ms_adapter.add(_msItem);
}
_mslv.setAdapter(_ms_adapter);
builder = new AlertDialog.Builder(mContext);
builder.setView(_dialog_layout);
alertDialog = builder.create();
alertDialog.show();
When I try it the debug presents the following on LogCat:

So the question is why and how to solve this problem ?
The second scenario is creating a new Activity and I already did that and it
worked:
Intent _i = new Intent(mContext, SourceDialog.class);
startActivity(_i);
startSubActivity(_i, 0);
The problem is how to obtain which element in the listview was selected ? How
to pass this information from one Activity to another ?

Vitorio.
