问题描述
我已尽力为Android导航抽屉重现UI设计. 我已经设计了nav标头，使其看起来像UI设计中的样子. 当我运行应用程序时，标题(nav_header_home.xml中的布局)在模拟器中不可见.
I have done my best to reproduce a UI design for an android navigation drawer. I have already designed the nav header to look like what is in the UI design. When I run the app, the header (the layout in nav_header_home.xml) is not visible in the simulator.
导航抽屉的nav_header_home.xml:
The nav_header_home.xml for the navigationdrawer:
