android - ListView 中的线性布局

Question

因此，我试图将一个具有两个 TextView 的 LinearLayout 放入一个 ListView 中，但我遇到了麻烦，并且程序一直在我尝试过的过程中崩溃。 ListView 将只有一个元素。我的线性布局的 xml 如下:

<ListView>
<LinearLayout
    android:orientation="vertical" 
    android:layout_height="wrap_content" 
    android:layout_width="fill_parent"
    android:minHeight="?android:attr/listPreferredItemHeight"
    android:gravity="center_vertical"
    android:drawablePadding="14dip"
    android:paddingLeft="15dip"
    android:paddingRight="15dip">
        <TextView 
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:textAppearance="?android:attr/textAppearanceLarge"/>
        <TextView 
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:textAppearance="?android:attr/textAppearanceSmall"/>
</LinearLayout>
</ListView>

如何在 ListView 中获取它？当我尝试将它放入 ListView 时，我在电话上收到一条错误消息，说对不起!应用程序意外停止。请再试一次。堆栈跟踪在下面。

我假设您正在尝试自定义列表项。您应该编写自己的自定义适配器来执行此操作。试试这个 tutorial或者您可以查看这些视频:

4. > Beautify your List: Rigth way to do it
