Solving on Menu Item click

`
searchbar.inflateMenu(R.menu.menu_main);
`
`
searchbar.getMenu().setOnMenuItemClickListener(this);
`
Then implement `PopupMenu.OnMenuItemClickListener`
Finally:

`
@Override
public boolean onMenuItemClick ( MenuItem item )
{
int id = item.getItemId ( );
switch ( id )
{
case R.id.menu_theme:
ThemeUtils.setAppTheme( this );
break;

case R.id.menu_settings:
NavigationUtils.openActivity (this , SettingsActivity.class);
break;

}
return true;
}
`

Start by locating the searchbar menu integration and the use of searchbar.inflateMenu(R.menu.menu_main) with searchbar.getMenu().setOnMenuItemClickListener(this). Review how PopupMenu.OnMenuItemClickListener and the menu_theme and menu_settings item IDs are handled; done means the requested menu-item click behavior is supported and verified in the Android project.
