android 5 and onClick in xml layout

Question

I have set android:onclick in xml for an imageButton and put that method in my activity. In android s below 5 it works fine but in android 5 it gives me Error.

My imageButton code:

<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"/>

My method code:

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

The error:

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

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

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

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

2) The activiy extends ActionBarActivity with appCompat theme.

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.

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"

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

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