<ImageButton 
     android:id="@+id/photo_detail"
     android:layout_width="wrap_content"
     android:layout_height="wrap_content"
     android:src="@drawable/detail_icon"
     android:layout_alignParentLeft="true"
     android:layout_centerVertical="true"
     android:background="@drawable/image_background"
     android:onClick="photoDetailButtonMethod"/>

我的方法code：

my method code:

public void photoDetailButtonMethod(View theButton)
{
  //something
}

错误：

通过查找错误，我可以看到它在 android.view.ContextThemeWrapper 寻找我的方法类，因此endup与 NoSuchMethodException 。

by looking the error i can see it searching for my method in android.view.ContextThemeWrapper class so it endup with NoSuchMethodException.

我不知道如何解决这个问题，任何帮助？

i can't figure out how to solve this, any help?

1）我已经加入工具：上下文=。PhotoViewerActivity在我的布局根

1) i already added tools:context=".PhotoViewerActivity" in the root of my layout.

2）的activiy延伸 ActionBarActivity 与 appCompat 主题。

2) the activiy extends ActionBarActivity with appCompat theme.

推荐答案

我有一个非常类似的问题，它只能发生在Android棒棒糖，虽然它工作正常的旧版本。看起来像在5.0中的错误或无证功能。

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

请确保在您的的ImageButton 所在的布局文件有否 安卓主题设置，即这样的事：

Make sure that in the layout file where your ImageButton resides there is no android:theme set, i.e. nothing like this:

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

相反，定义的Andr​​oidManifest.xml 应用程序元素应用程序的主题：

Instead, define your application theme in AndroidManifest.xml application element:

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