在主活动MainActivity的onCreate()方法中，创建两个用于保存列表项图片id和文字的数组，并将这些图片id和文字添加到List集合中，然后创建一个SimpleAdapter简单适配器，具体代码如下

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="horizontal" >

    <ImageView
        android:id="@+id/image"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:paddingLeft="10dp"
        android:paddingTop="20dp"
        android:paddingBottom="20dp"
        android:adjustViewBounds="true"
        android:maxWidth="72dp"
        android:maxHeight="72dp"
         />

    <TextView
        android:id="@+id/title"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:text="TextView" />
