ListView中的LinearLayout
ListView中的LinearLayout
提问于 2011-07-28 22:14:39
所以我试着把一个有两个TextViews的LinearLayout放在一个ListView里面，但是我遇到了麻烦，程序总是崩溃。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中实现此功能？当我试着把它放在列表视图中时，我在电话上收到一个错误，说对不起！应用程序意外停止。请再试一次。堆栈跟踪如下所示。

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实现这一点。试试这个tutorial，或者你可以看看这些视频：

- Transitioning to ListActivity

- Beautify your List: Rigth way to do it

老实说，这个错误让我的眼睛很难理解。但通常情况下，您应该能够创建一个包含一个子元素的listview。
我想说的是：
<ListView>
<LinLayout>
<TextView/>
<TextView/>
</LinLayout>
</ListView>这应该是可行的，因为ListView只允许一个子进程。但是你的LinearLayout可以有你想要的数量。如果有一个错误，它可能是你的布局充气。
