I've looked through the XML resources trying to determine where this shape is defined but I'm feeling a bit overwhelmed.

问题 I am working on a project and I have run into some problems. I haven't worked with the layouts very much so I don't know if this is possible or not. In the picture I have added the project mock-up. For the lower screen resolution it looks fine, but when I put the app on 5 inch device, this orange area is too high and I wanted to know if it is possible somehow to get that area centered.
