Default Android Automation Testing

I've an apk to be tested using Robotium. In the application I'm going to test there is a custom view(Window) on which there are some text and numeric parameters drawn using ownerDrawn and Paint. The custom view is a child of the relative layout. Since I'm not able to get the resource id of the parameters drawn on the custom view,I'm finding it hard to test the existance of parameters and read the value of the parameter on that view. Please help me out with a solution on how would I do that.

The Custom View is similar to the one attached here.

Please suggest me if there is any other way to achieve this.

Thanks
