Android Studio不断用固定的dp值替换match_parent [英] Android studio keeps replacing match_parent with fixed dp value

问题描述

Android Studio(v 2.3.1)一直用固定的dp替换替换RelativeLayout的match_parent.例如，当我输入match_parent作为宽度时，它将替换为368dp.在测试应用程序时，我发现RelativeLayout确实是错误的.

Android studio (v 2.3.1) keeps replacing the match_parent of a RelativeLayout with a fixed dp vanue. For example, when I type match_parent as the width, it replaces it with 368dp. When I test the app, I see that the RelativeLayout indeed is wrong.

有人知道如何解决此问题吗?

Does anyone know how to fix this?
