Combo box / Drop down list box in Android

As usual doing something simple in Android is frustrating - this time: a simple Combo (or DropDownList). The little and important tweak - calling "setDropDownViewResource" to set the style of the items in the dialog box.

XML:
<spinner id="@+id/spinner" layout_width="wrap_content" android:layout_height="wrap_content" />

Code to add the data:

Spinner spinner = (Spinner)this.findViewById(R.id.spinner);
ArrayAdapter<String> adapter = new ArrayAdapter<String>(
        this,
        android.R.layout.simple_spinner_item,
        new String[] { "1", "2", "3" });
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner.setAdapter(adapter);

A common task is to populate a spinner using a string array defined in a resource file. Here's a function which do just that:

 public static void populateSpinnerWithArray(Spinner spinner, int stringArrayResId) {
     ArrayAdapter<String> adapter = new ArrayAdapter<String>(
             spinner.getContext(),  
             android.R.layout.simple_spinner_item,
             spinner.getContext().getResources().getStringArray(stringArrayResId));  
     adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);  
     spinner.setAdapter(adapter);  
 }
