布局：

item_one

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

<TextView
    android:id="@+id/tv_content"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:text="Hello"
    android:textColor="#AAFFBB"
    />

</LinearLayout>
item_two

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

    <ImageView
        android:id="@+id/iv_image"
        android:layout_width="wrap_content"
