MonoDroid custom View doesn't show child

Question

I have pretty simple custom view:

public class TestControl : RelativeLayout
{
    private readonly Context _context;

    private TextView _textLabel;

    public TestControl(Context context) : base(context)
    {
        _context = context;

        LayoutParameters = new LayoutParams(300, 200);
        SetBackgroundColor(Color.Green);

        _textLabel = new TextView(_context);
        _textLabel.SetText("Test test test test test test", TextView.BufferType.Normal);
        _textLabel.SetTextColor(Android.Graphics.Color.Black);
        _textLabel.LayoutParameters = new ViewGroup.LayoutParams(200, 50);
        _textLabel.SetBackgroundColor(Color.Red);

        AddView(_textLabel);
    }

    protected override void OnLayout(bool changed, int l, int t, int r, int b)
    {

    }
}

When I try to add it as a view into my main activity layout:

var myControl = new TestControl(this);
myMainLayout.AddView(myControl);

I see only green recangle(300 x 200) but no TextView.

What am I doing wrong? Any help on how to show at least TextView inside some colored layout much appreciated, as I need actualy much more complicated custom view.

Thanks in advance.

You'll probably need to do something similar to what's explained here. SetWillNotDraw can play some tricks on you in such circumstances.
