Annotation Type OnItemSelected

@Target(value=METHOD)
 @Retention(value=CLASS)
public @interface OnItemSelected

Bind a method to an OnItemSelectedListener on the view for each ID specified.

  @OnItemSelected(R.id.example_list) void onItemSelected(int position) {
   Toast.makeText(this, "Selected position " + position + "!", Toast.LENGTH_SHORT).show();
 }
 

Any number of parameters from onItemSelected may be used on the method.

To bind to methods other than onItemSelected, specify a different callback.

  @OnItemSelected(value = R.id.example_list, callback = NOTHING_SELECTED)
 void onNothingSelected() {
   Toast.makeText(this, "Nothing selected!", Toast.LENGTH_SHORT).show();
 }
