I'm writing a fairly complex ListView, which (among other things) requires formatting Views in each list item.
To give me full control over how the views are bound in each list item, I subclassed CursorAdapter in this manner:
public class MyAdapter extends CursorAdapter {
public final LayoutInflater mInflater;
public MyAdapter(Context context, Cursor c) {
super(context, c);
mInflater = LayoutInflater.from(context);
}
@Override
public void bindView(View view, Context context, Cursor cursor) {
final ToggleButton tButton = (ToggleButton) view.findViewById(R.id.tbutton);
tButton.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
// start activity based on a pending intent
}
});
}
}
The issue is that my ToggleButton click listener should start an activity based on a pending intent. The pending intent is instantiated in the activity which utilises this customized adapter.
I'm aware I could have used a SimpleCursorAdapter in the main Activity with a ViewBinder so that launching the intent would only be necessary from the main Activity. But SimpleCursorAdapter is not quite right since I don't map columns straight to views.
However, the alternative I have here would suggest accessing the main Activity's data from a cursor subclass. I feel that there must be a better way to design the application.
Taking a cue from the API Demos - specifically EfficientAdapter, I have declared the CursorAdapter sublcass as an inner class of my activity.
This avoids passing the pending intent around outside of the main activity.
