我正在构建一个Android应用程序，使用一堆switch语句在视图之间切换。一切都很顺利，直到我添加了一些案例，导致应用程序启动时发生致命错误。这些案例由XML中的onClick语句调用。有争议的案例块实际上是可以正常工作的一组语句的一部分。任何人都可以看到我失踪的东西吗？什么导致致命的错误？我包含了破碎的代码和工作代码以及logCat文件的片段。该XML的Switch case语句在我的Android应用程序中导致致命错误

的例子，将调用断开关情况：
<RelativeLayout android:id="@+id/level07_layout00"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="@drawable/vlayoutup"
android:visibility="gone">

这里是破的java的一个片段：
case R.id.level07_backButton01:
RelativeLayout bB017 = (RelativeLayout)findViewById(R.id.level07_layout00);
bB017.setVisibility(View.VISIBLE);
RelativeLayout bB017b = (RelativeLayout)findViewById(R.id.level07_layout01);
bB017b.setVisibility(View.GONE);
break;
case R.id.level07_backButton02:
RelativeLayout bB027b = (RelativeLayout)findViewById(R.id.level07_layout01);
bB027b.setVisibility(View.VISIBLE);
RelativeLayout bB027 = (RelativeLayout)findViewById(R.id.level07_layout02);
bB027.setVisibility(View.GONE);
break;
case R.id.level07_backButton03:
RelativeLayout bB037 = (RelativeLayout)findViewById(R.id.level07_layout02);
bB037.setVisibility(View.VISIBLE);
RelativeLayout bB037b = (RelativeLayout)findViewById(R.id.level07_layout03);
bB037b.setVisibility(View.GONE);
break;
下面是作品的代码片段来自同一个块：
case R.id.level07_backButton16:
RelativeLayout bB167 = (RelativeLayout)findViewById(R.id.level07_layout15);
bB167.setVisibility(View.VISIBLE);
RelativeLayout bB167b = (RelativeLayout)findViewById(R.id.level07_layout16);
bB167b.setVisibility(View.GONE);
break;
case R.id.level07_backButton17:
RelativeLayout bB177 = (RelativeLayout)findViewById(R.id.level07_layout13);
bB177.setVisibility(View.VISIBLE);
RelativeLayout bB177b = (RelativeLayout)findViewById(R.id.level07_layout17);
bB177b.setVisibility(View.GONE);
break;
case R.id.level07_backButton18:
RelativeLayout bB187 = (RelativeLayout)findViewById(R.id.level07_layout17);
bB187.setVisibility(View.VISIBLE);
RelativeLayout bB187b = (RelativeLayout)findViewById(R.id.level07_layout18);
bB187b.setVisibility(View.GONE);
break;
正如你所看到的，我认为，两个开关盒的块是相同的。我认为的一个重要线索就是在logCat中：VFY：无效的切换目标。
如果您需要了解更多信息，请让我知道。先谢谢您的帮助！
我看不到backButton02或03的定义。 （或后来的16/17/18 - 是整个XML？ – jkhouw1 2011-05-17 03:26:29
这不是整个XML，只是一个例子，它几乎是一堆类似的块，但它们都具有相同的imageButtons用于后退，关闭和下一个。 – Bret 2011-05-17 04:04:22
你在这个XML中有多少个视图？多少个布局？假设你没有在Button02或Button03上的xml中输入错误，是否有可能超过了#of视图或布局的限制？ – jkhouw1 2011-05-17 09:37:52
