Annotation Type OnPageChange

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

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

  @OnPageChange(R.id.example_pager) void onPageSelected(int position) {
   Toast.makeText(this, "Selected " + position + "!", LENGTH_SHORT).show();
 }
 

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

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

  @OnPageChange(value = R.id.example_pager, callback = PAGE_SCROLL_STATE_CHANGED)
 void onPageStateChanged(int state) {
   Toast.makeText(this, "State changed: " + state + "!", LENGTH_SHORT).show();
 }
