How do I open the SearchView programmatically?

Question

There is this widget for the ActionBar which called \'SearchView\'. When it\'s not in use, it looks like this:

Answer 1

For androidx.appcompat.widget.SearchView,

searchView.setIconifiedByDefault(true)   // didn't work

searchMenuItem.expandActionView()  // didn't work

MenuItemCompat.expandActionView(searchMenuItem) // didn't work

searchView.onActionViewExpanded()  // didn't work

The following worked for me,

searchView.findViewById(R.id.search_button).performClick()
