ImageButton click does not work

I tried two different ways to set up the event for an ImageButton but neither has worked. First I tried by adding onClick in the axml file:

<ImageButton
    android:src="@drawable/homeInfoButtonImages"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:id="@+id/homeInfoButton"
    android:layout_marginLeft="200dp"
    android:layout_marginTop="600dp"
    android:background="@null"
    android:onClick="infoButtonClick" />

In the Activity.cs:

    private void infoButtonClick()
    {
        Console.Write("Clicked");
    }

The app crashes as soon the button is clicked.

The second method I tried in Activity.cs:

    protected override void OnCreate(Bundle bundle)
    {
        base.OnCreate(bundle);
        SetContentView(Resource.Layout.Home);

        // Create your application here
        ImageButton button = FindViewById<ImageButton>(Resource.Id.homeInfoButton);

        button.Click += delegate
        {
            infoButtonClick();
        };
    }

    private void infoButtonClick()
    {
        Console.Write("Clicked");
    }

Nothing happens when the button is clicked...

What could be causing this issue?

Console.WriteLine might have some unexpected behaviour (at least what I have experienced). The below code works fine for me.

        FindViewById<ImageButton> (Resource.Id.imageButton1).Click += (s, e) =>
            Log.Info (s.ToString (), "Image button clicked!");

I code using java in eclipse.I had the same problem. So I dont know whether it will work for you.

try public void infoButtonClick() instead of private.

This solution worked for me. Thought it might help.

In the method that is called from the onClick attribute on the xml, you must pass an argument of the view, and it must be public:

public void infoButtonClick(View v)
{
  Console.Write("Clicked");
}

As you can read here

Please remove Console.Write("Clicked"); and test.
