Subject: [PATCH] Android Annotations support - inflate view from existing view

It can be used in @AfterViews method

@AfterViews
protected void afterViews() {
   Binder.InflateResult inflateResult = Binder.inflateViewFromExistingView(this, findViewById(R.id.drawer_layout), R.layout.activity_init);
   Binder.bindView(this, inflateResult, mViewModel);
}
