this is how i use the adapter

ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(
getBaseContext(), R.array.listMedRes, android.R.layout.simple_spinner_item);

Since you are using AppCompat-v21, you can take advantage of the new material design styles attributes:

colorPrimary: your app branding color for the app bar, applies to action bar

colorPrimaryDark: darker variant for the status bar and contextual app bars

colorAccent: lets you define bright complement to the primary branding color. By default, this is the color applied to framework controls (via colorControlActivated)

colorControlNormal: color applied to framework controls in their normal state

colorControlActivated: applied to framework controls in their activated

Here is an example for you


<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <!-- colorPrimary is used for the default action bar background -->
    <item name="colorPrimary">@color/primary</item>
    <!-- colorPrimaryDark is used for the status bar -->
    <item name="colorPrimaryDark">@color/primary_dark</item>
    <!-- colorAccent is used as the default value for colorControlActivated which is used to tint widgets -->
    <item name="colorAccent">@color/accent</item>
    <item name="colorControlNormal">@color/primary</item>


    <color name="primary">#ff0000ff</color>
    <color name="primary_dark">#ff0000af</color>
    <color name="accent">#870000ff</color>
    <color name="white">#ffffffff</color>

Here is how it looks
