Android Lollipop, add popup menu from title in toolbar

Question

I\'m unable to see how adding a popup menu from the title is accomplished like is shown in many of the material design examples. Any help would be much appreciated.

Answer 1

I came across this question while I was trying to find a solution to prevent the popup to overlay the spinner and I would like to leave here an alternative solution to this question as its possible to add the spinner to the toolbar using the menu.xml as well

activity_main.xml

menu_main.xml

Your Activity

It will be necessary to override the onCreateOptionMenu() method, then use getMenuInflater() to inflate the menu file created earlier.

You will also need to get the Spinner item and set an adapter to it as you would normally do.

   @Override
public boolean onCreateOptionsMenu(Menu menu) {

    getMenuInflater().inflate(R.menu.menu_main, menu);

    //Get Spinner item from menu

    MenuItem spinnerMenuItem = menu.findItem(R.id.spinner);
    final Spinner spinner = (Spinner) MenuItemCompat.getActionView(spinnerMenuItem);

    //Set adapter whichever way you prefer (from the resource or manually)

    final ArrayAdapter spinnerAdapter = ArrayAdapter
            .createFromResource(this, R.array.items_array, android.R.layout.simple_spinner_dropdown_item);
    spinnerAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
    spinner.setAdapter(spinnerAdapter);

    return true;

}

Style.xml

Finally, if you want to customize your spinner
