If you would like to setup the search facility inside your Fragment, just add these few lines:
Step 1 - Add the search field to you toolbar:
<item
android:id="@+id/action_search"
android:icon="@android:drawable/ic_menu_search"
app:showAsAction="always|collapseActionView"
app:actionViewClass="android.support.v7.widget.SearchView"
android:title="Search"/>
Step 2 - Add the logic to your onCreateOptionsMenu()
import android.support.v7.widget.SearchView; // not the default !
@Override
public boolean onCreateOptionsMenu( Menu menu) {
getMenuInflater().inflate( R.menu.main, menu);
MenuItem myActionMenuItem = menu.findItem( R.id.action_search);
searchView = (SearchView) myActionMenuItem.getActionView();
searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
@Override
public boolean onQueryTextSubmit(String query) {
// Toast like print
UserFeedback.show( "SearchOnQueryTextSubmit: " + query);
if( ! searchView.isIconified()) {
searchView.setIconified(true);
}
myActionMenuItem.collapseActionView();
return false;
}
@Override
public boolean onQueryTextChange(String s) {
// UserFeedback.show( "SearchOnQueryTextChanged: " + s);
return false;
}
});
return true;
}
