<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:orientation="vertical"    tools:context=".MainActivity" >    <Spinner        android:id="@+id/spinner1"        android:layout_width="match_parent"        android:layout_height="wrap_content" >    </Spinner>    <Spinner        android:id="@+id/spinner2"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:layout_marginTop="10sp" >    </Spinner></LinearLayout>
