NavigationView get/find header layout

Question

In my NavigationView I have a header layout with id \'viewId\' with active buttons. To setup those buttons, I do the following in activity\'s onPostCreate:

Answer 1

This is how I did it using ButterKnife and it works for me.

protected static class HeaderViewHolder {

    @BindView(R.id.button)
    Button button;

    HeaderViewHolder(View view) {
        ButterKnife.bind(this, view);
    }
}

and then use this view holder like this :

View header = navigationView.getHeaderView(0);
headerViewHolder = new HeaderViewHolder(header);
