IntelliJ 和 android.support.v7.widget.GridLayout [英] IntelliJ and android.support.v7.widget.GridLayout

问题描述

我在 IntelliJ 项目中设置支持 v7 GridLayout 库或在我的代码中正确引用它时遇到问题.

I am running into trouble either setting up the support v7 GridLayout library in my IntelliJ project, or properly referencing it in my code.

我目前在我的项目中使用 ActionBarSherlock 和 Facebook 库，并以相同的方式设置支持 GridLayout 库(在 src 文件夹中没有源，我告诉 IntelliJ 使用项目目录作为 jar 文件夹).一切看起来都很好，构建并部署到我的测试设备上，但是当我尝试扩大布局时，我的应用程序崩溃了.

I currently use the ActionBarSherlock and Facebook libraries in my project, and have set up the support GridLayout library the same way (not having source in the src folder, I told IntelliJ to use the project dir as a jar folder). Everything looked fine, built and deployed to my test device, but when I tried to inflate the layout, my app crashed.

IntelliJ 还告诉我，我的 GridLayout 在 XML 设计器中这里不允许"，我无法在各种搜索引擎中找到任何帮助.我的布局(截断长度)如下:

IntelliJ is also telling me that my GridLayout is "not allowed here" in the XML designer, which I unable to find any help on in various search engines. My layout (truncated for length) is as follows:

Coles 注释:我在一个 RelativeLayout 和一个位于顶部的 LinearLayout 支持 GridLayout，锚定在 RelativeLayout 的底部.

Coles Notes: I have a support GridLayout in a RelativeLayout and a LinearLayout that sits on top, anchored at the bottom of the RelativeLayout.

日志表明我错过了一堂课.我希望我只是没有正确设置图书馆，因为我想不出还有什么可能.希望有一些 IntelliJ/Android 知识的人可以为我指明正确的方向.

The log indicates I am missing a class. I am hoping I just didn't set the library up properly, as I can't think of what else it could be. Hopefully someone with some IntelliJ/Android knowledge can point me in the right direction.

如果这个问题缺少一些信息，请放轻松 - 这是我第一次尝试使用 stackoverflow 寻求帮助.

Please go easy on me if this question is missing some info - this is my first try at using stackoverflow to ask for help.

提前致谢

推荐答案

好的，我想通了.原来是配置问题.这是我设置支持 GridLayout 库以及在代码中引用类的操作.

Ok, I figured this out. Turns out it was a configuration issue. Here is what I did to set up the support GridLayout library, as well as reference the classes in code.

• 将 [android-sdk-folder]/extras/android/support/v7/gridlayout 文件夹复制到您的项目 libs 文件夹中

在 IntelliJ 中设置支持 GridLayout 库:

Set up support GridLayout library in IntelliJ:

• 项目结构 -> 项目设置面板中的模块 -> 新建模块
• 从头开始创建模块 -> 下一步
• 命名项目，浏览到您的 libs/gridlayout 文件夹并选择作为内容根，保留由内容根分配设置的模块根，然后选择 Android 模块类型 -> 下一步
• 不要创建源目录 -> 下一步
• 不要创建Android应用程序结构->完成
• 在项目设置"窗格中选择 Facet -> 选择您的新模块 -> 选中是库项目"

在 IntelliJ 中添加对项目的依赖:

Add dependancy to project in IntelliJ:

• 在项目设置面板中选择模块 -> 选择您希望使用支持 GridLayout 的项目
• 选择依赖项选项卡 -> 单击 [+] 添加新的模块依赖项
• 从上一节中选择您的支持库

您还需要在 support project libs 目录中添加对 support v7 GridLayout jar 文件的引用.

You also need to add a reference to the support v7 GridLayout jar file in the support project libs dir.

• 仍在依赖项选项卡上 -> 单击 [+] 添加新库 -> Java
• 浏览到 libs/gridlayout/libs 文件夹并选择 support v7 GridLayout .jar
• 选择级别(我只需要项目级别)-> 确定

希望这对其他人有所帮助 - 我大部分时间都浪费在它上面.=|

Hopefully this helps someone else - I wasted most my day on it. =|
