[android] How to customize a Spinner in Android

This worked for me :

ArrayAdapter<String> adapter = new ArrayAdapter<String>(getActivity(),R.layout.simple_spinner_item,areas);
            Spinner areasSpinner = (Spinner) view.findViewById(R.id.area_spinner);
            areasSpinner.setAdapter(adapter);

and in my layout folder I created simple_spinner_item:

<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@android:id/text1"
android:layout_width="match_parent"
// add custom fields here 
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceListItemSmall"
android:gravity="center_vertical"
android:paddingStart="?android:attr/listPreferredItemPaddingStart"
android:paddingEnd="?android:attr/listPreferredItemPaddingEnd"
android:minHeight="?android:attr/listPreferredItemHeightSmall"
android:paddingLeft="?android:attr/listPreferredItemPaddingLeft"
android:paddingRight="?android:attr/listPreferredItemPaddingRight" />
