Android – Make whole search bar clickable

This can be simply done by setting Iconified to false on OnClick of SearchView.

searchBar.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        searchBar.setIconified(false);
    }
});

Hopefully it will help.

UPDATE:

You can also use it directly in your XML

app:iconifiedByDefault="false"
