在我的应用程序中使用 Android 默认 GPS 开-关对话框

Question

在我们的应用程序中，我们希望集成 android 默认 GPS 对话框。当 GPS 关闭时出现的相同对话框，我们在 google 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片。

单击 "No" 选项将关闭对话框。
点击"Yes"选项将直接激活设备的GPS。

下面为 OLA 应用程序出现的对话框 (ANDROID L):

下面为 OLA 应用程序出现的对话框 (ANDROID KIT_KAT):

下面的 Google 地图 (ANDROID L) 出现的对话框：

我们现有的实施是当 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，he/she 可以从那里打开位置。

期待答案。提前致谢。

Answer 1

您需要使用最新版本的Google Play 服务。最新版本有一个对话框来激活获取 GPS 所需的所有东西。

来自 Android 开发者 Play 服务文档，

Location settings - While the FusedLocationProviderApi combines multiple sensors to give you the optimal location, the accuracy of the location your app receives still depends greatly on the settings enabled on the device (GPS, wifi, airplane mode, and others). Using the new SettingsApi class, you can bring up a Location Settings dialog which displays a one-touch control for users to change their settings without leaving your app.

Link 指向 Play 服务版本文档。 7.0版本引入了这个新提示。

Answer 2

Ola Cabs 正在使用新发布的设置 API 来实现此功能。根据新的 API，用户无需导航至设置页面即可启用位置服务，从而实现无缝集成。请阅读 this 了解更多详情。

Answer 4

循序渐进

第一步检查是否支持GPSDevice

步骤 2 hasGPSDevice true 检查 MarshMallow Permission

Step 3 MarshMallow Permimssion true check Location already on or not

步骤 4 如果位置打开，则调用所有 Gps 跟踪器并获取经纬度

第 5 步如果位置关闭，则调用所有位置对话框与 Google 地图
