我不知道为什么，但我得到这个异​​常：

  java.lang.IllegalStateException：找不到在活动课android.view.ContextThemeWrapper为的onClick处理方法onButtonClick（视图）在视图类android.widget.Button ID为 button19 

在我的应用程序，我不知道如何解决它。出于某种原因，它只是引发此异常在平板电脑布局。有什么建议？

解决方案

我有一个非常类似的问题，它发生仅适用于Android L当它工作在旧version.Looks就像在5.0中的错误或无证功能罚款。

解决方案为我工作：

 删除机器人：主题=@风格/ Base.Theme.AppCompat.Light 

从layout.xml。在定义这样的Andr​​oidManifest.xml中的应用程序元素应用程序的主题：

 ＆lt;应用         ...         机器人：主题=@安卓风格/ Theme.Holo.Light         ...＆GT; 

I'm not sure why but I'm getting this exception:

java.lang.IllegalStateException: Could not find a method onButtonClick(View) in the activity class android.view.ContextThemeWrapper for onClick handler on view class android.widget.Button with id 'button19'

I had a very similar problem, it happens only on Android L while it works fine on the older version.Looks like a bug or undocumented feature in 5.0.

Solution that worked for me:

remove android:theme="@style/Base.Theme.AppCompat.Light"

from your layout.xml. Define your application theme in AndroidManifest.xml application element like that:

<application 
         ...
         android:theme="@android:style/Theme.Holo.Light"
         ...  >
