Hi all:
I am writing a adapter for a specific app, the problem I met is:
I have only 1 listview in main.xml, and the row style is defined in
file_row.xml. If I simply use
list.setAdapter(new ArrayAdapter<String>(this, R.layout.file_row,
R.id.file_name, items));
where items is a ArrayList<String>, everything works well.
But if I use my custom Adapter, say,
list.setAdapter(new MyOwnListAdapter(this, filename));
and in the class of MyOwnListAdapter, the code has been simplified as
class MyOwnListAdapter extends ArrayAdapter<String> {
// Constructor
public IconifiedTextListAdapter(Activity context,
ArrayList<String>
filename_list) {
super(context, R.layout.file_row, R.id.file_name,
filename_list);
}
public View getView(int position, View convertView, ViewGroup
parent) {
return parent;
}
}
But I always met the problem which is:

I thought the self-defined Adapter class actually has only one line of
valid execution, which is
super(context, R.layout.file_row, R.id.file_name, filename_list);
It's essentially identical to direct calling of
list.setAdapter(new ArrayAdapter<String>(this, R.layout.file_row,
R.id.file_name, items));
Then why I always got this error if I call my own Adapter?
Any hint or suggestion would be very appreciated.
