推荐答案

看起来你已经添加gridlayout.jar到项目的lib文件夹。

It looks like you have added gridlayout.jar to the projects lib folder.

它的库项目的资源。您需要引用该库项目，你的android谟

Its a library project with resources. You need to reference the library project in your android projet

该库位于＆LT; SDK＆GT; /演员/安卓/支持/ V7 /网格布局/ 目录下载Android支持库后

This library is located in the <sdk>/extras/android/support/v7/gridlayout/ directory after you download the Android Support Libraries.

请添加库与资源
