我只是更改了 highscores.xml，但当我尝试在菜单中选择 Highscores 时突然出现一些奇怪的错误。 日志猫

它在高分 xml 中工作时是这样的
<?xml version="1.0" encoding="utf-8" ?>
- <RelativeLayout android:id="@+id/widget32" android:layout_width="fill_parent" android:layout_height="fill_parent" xmlns:android="http://schemas.android.com/apk/res/android">
<TextView android:text="This is where you would show any options your game has" android:id="@+id/TextView01" android:layout_width="wrap_content" android:layout_height="wrap_content" />
</RelativeLayout>
但是当我把它改回来时 - 错误并没有消失/发生了什么？我该如何解决这个问题？
最佳答案
您一定还更改了其他内容。您的 Highscores Activity 类正在扩展 ListActivity，这要求您的布局 xml 中存在一个 ListView，其 id 为 android.R.id.list，例如
<ListView
android:id="@android:id/list"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
/>
