我正在尝试使用ViewFlipper，但我在setContentView(R.layout.activity_main);行收到此错误;
当我回溯时，我只在添加第二个LinearLayout时出现此错误。 我查看了使用ViewFlipper的示例，我没有看到问题。
这是XML文件：

答案 0 :(得分：5)
下面：
<linearLayout
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
...
</linearLayout>
应该是：
<LinearLayout
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
...
</LinearLayout>
（上限）
请注意，XML区分大小写。
