带有自定义项目的Android ListView，其中一个字段是另一个自定义项目列表(非列表视图需要不可滚动)

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

    <!-- 其他字段 -->
    <TextView
        android:id="@+id/textView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="字段1" />

    <!-- 显示另一个自定义项目列表的容器 -->
    <LinearLayout
