我的问题是使用材料设计:

未对齐
uses-material-design: true //column 3
# To add assets to your application, add an assets section, like this:
assets://column 4
简单的解决方案是确保“我的资产”部分与“我的使用材料设计”部分保持一致,换句话说,它们应与以下代码放在同一列中:
uses-material-design: true //column 3
# To add assets to your application, add an assets section, like this:
assets://column 3
