The android:onClick attribute on views should be wired up to a public method on
the containing method.  Instead it is throwing a java NoSuchMethodException.

Reproducible: Always

Steps to Reproduce:
1. Create a new MonoDroid Application
2. Edit the Main.axml view

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
<Button  
    android:id="@+id/MyButton"
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:text="@string/Hello"
    android:onClick="MyButton_OnClick"
    />
</LinearLayout>

3. Create an Activity

[Activity(Label = "MonoDroidSandbox", MainLauncher = true)]
    public class Activity1 : Activity
    {
        protected override void OnCreate(Bundle bundle)
        {
            base.OnCreate(bundle);
            SetContentView(Resource.Layout.Main);
        }

        public void MyButton_OnClick(View view)
        {
            Log.Verbose("MonoDroidSanbox", "OnClick!");
        }
    }
public void MyButton_OnClick(View view) {
  Log.Verbose("MonoDroid", "My Button Clicked!");
}

4. Run the application and click the button

Actual Results:  
adb logcat
