将MasterDetailPage的背景设置为透明

Question

When I try to set the background color of the Master (of the MasterDetailPage) to transparent, it stays white.

Basically what I would want to see, is that the color from the detail page is shown through the Master.

FOR EXAMPLE (If the above were true, then the background color of this MasterDetailPage would be red (Yes I know I can just set the background colour as red, but I want it to be transparent ))

Answer 1

After seeing the TabletMasterDetailRenderer's documentation , we can find that the master or detail page which we create in PCL will be added on the _masterController.View and _detailController.View .

So when we set its BackgroundColor to Transparent , the page will still be white as what we look. We should also set the _masterController.View 's BackgroundColor .

We can find the _masterController in renderer and set it like:

public override void ViewWillLayoutSubviews()
{
    base.ViewWillLayoutSubviews();

    var master = ViewControllers[0];
    master.View.BackgroundColor = UIColor.Clear;

    //This is Detail ViewController
    var detail = ViewController.ChildViewControllers[1];
}

Create a custom renderer for MasterDetailPage and put this code in it.
