使用我的应用程序中的Android默认GPS开 - 关对话框
在我们的应用程序中，我们想要集成Android默认GPS对话框。 GPS关闭时出现的同一个对话框，我们在谷歌地图应用程序中按下我的位置按钮。还附上了我要整合的对话框的图像。
- 点击＆＃34;否＆＃34;选项将关闭对话框。
- 点击＆＃34;是＆＃34;选项将直接激活设备的GPS。
为OLA应用程序显示对话框（ANDROID L）：
为OLA应用程序显示对话框（ANDROID KIT_KAT）：
对话框出现在谷歌地图下面（ANDROID L）：
我们现有的实施方案是当GPS关闭时，我们将应用程序重定向到设备的默认位置设置屏幕，他/她可以从中打开位置。
期待寻找答案。 提前谢谢。

您需要使用最新版本的Google Play服务。最新版本有一个对话框，可以激活所有需要的东西来获取GPS。
来自Android Developer Play Service文档，
位置设置 - 虽然FusedLocationProviderApi结合了多个传感器以提供最佳位置，但应用程序接收位置的准确性仍然在很大程度上取决于设备上启用的设置（GPS，wifi，飞行模式等）。使用新的SettingsApi类，您可以打开一个“位置设置”对话框，该对话框显示一键式控件，供用户无需离开您的应用即可更改其设置。
Link指向Play服务版文档。 7.0版引入了这个新提示。

Ola Cabs正在使用新发布的Settings API来实现此功能。根据新API，用户无需导航到设置页面即可启用位置服务，从而实现无缝集成。有关详细信息，请阅读this。
答案 3 :(得分：0)
循序渐进
第1步检查是否支持GPS设备支持
第2步hasGPSDevice真实检查MarshMallow Permimssion
第3步MarshMallow Permimssion真实检查位置是否已经开启
步骤4如果位置在CAll Gps Tracker上并获取Lat Long
步骤5如果位置oFf然后CAll位置对话与AS Google地图相同
