There seems to be good support for onClick related listeners, but not UI elements that have custom listeners, (e.g. SeekBar.OnSeekBarChangeListener).

You could build a @Listener annotation that could take the id of a specific UI element and based on that element's type and the name of the method being annotated, infer what listener to bind.

The below example could delegate the onProgressChanged method of SeekBar.OnSeekBarChangeListener to the annotated class.

@Listener(R.id.mySeekBar)
public void onProgressChanged(...)
