問題添加gridlayout支持庫到項目？

Question

當我點擊我的窗口小部件，使用了GridLayout支持庫，我得到這個錯誤：

我跟着官方Android開發人員指南，以支持庫添加到我的項目，但我仍然得到錯誤。

正如我相信這或多或少是我的錯某處沿線繼承人的步驟，我把添加它：

1）赴文件 - >導入 - >將現有Android代碼到Workspace->發現V7 GridLayout的文件，並點擊完成

2）又到了支持GridLayout的包，到庫文件夾，右鍵點擊.jar文件，並將其添加到我的構建路徑（我做了bin文件相同）

3）點擊我自己的項目 - >屬性 - >庫窗格 - >添加JAR（如下所示）

然後我也有訂單和出口標籤如下標註：

隨後兩個庫在我的項目「引用的庫」部分顯示出來。

但無論我做什麼，我仍然得到同樣的錯誤。我是否正確地做這件事？

Answer 1

您的步驟不正確。取而代之的是：

3)Clicked on my own project->Properties->Library pane->Add JARs (as seen below)

做到這一點（從指令Adding libraries with resources部分）：

1. In the Project Explorer, right-click your project and select Properties.
2. In the Library pane, click Add.
3. Select the library project and click OK. For example, the appcompat project should be listed as android-support-v7-appcompat.
4. In the properties window, click OK.

除了使用網格佈局而不是程序兼容性，當然

此外，您所做的其餘步驟（使用「構建和導出」選項卡）應完成網格佈局項目，而不是您的自己的項目（在說明的同一部分也有詳細說明）。
