Recyclerview 适配器上的 GoogleAPIClient
GoogleAPIClient on recyclerview adapter
此应用程序有一个片段，可在单个 table 数据库上执行 CRUD 操作。
在绘制 FAB 和 recyclerview 的 class 上完成。
FAB 打开带有插入表单的 alertDialog。
recyclerview 将数据库行显示为卡片视图。每个卡片视图都有一个编辑按钮和一个删除按钮。
编辑按钮打开一个带有编辑表单的警告对话框。
数据库存储每个都有起点和终点的旅程。
当输入或编辑地点时，用户会得到建议。
为此我使用了 Google Places Web 服务 API 但我注意到我必须使用 Google 为 Android 放置 API，因此 GoogleApiClient
请注意，该应用程序运行良好，成功执行了 CRUD，甚至从 Web 服务获得了方向建议。
我能够使插入表单使用正确的 API，但不能使编辑表单使用。
