推荐答案

您粘贴的内容看起来像是列表行的自定义布局，而不是ListActivity.

What you've pasted looks like a custom layout for the list rows, not the ListActivity.

从Android文档中找到此处:

From the Android documentation found here:

屏幕布局

ListActivity具有默认布局，该布局由屏幕中心的单个全屏列表组成.但是，如果需要，可以通过使用onCreate()中的setContentView()设置自己的视图布局来自定义屏幕布局.为此，您自己的视图必须包含ID为"@android:id/list"的ListView对象. (或列出是否在代码中)

ListActivity has a default layout that consists of a single, full-screen list in thecenter of the screen. However, if you desire, you can customize the screen layout by setting your own view layout with setContentView() in onCreate(). To do this, your own view MUST contain a ListView object with the id "@android:id/list" (or list if it's in code)
