<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/activity_main"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    >

    <Spinner
        android:id="@+id/simple"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:entries="@array/languages"
        android:prompt="@string/tip"
        android:layout_marginTop="60dp"
        />

    <Spinner
        android:id="@+id/spinner"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:prompt="@string/tip"
        android:layout_marginTop="20dp"
        />
