2 个解决方案

This is a duplicate of Requesting permissions on Android wear , but SO won't let me mark it as such because the OP didn't accept my answer there. 这是对Android Wear的Requesting许可的重复，但是SO不允许我将其标记为此类，因为OP在那里不接受我的回答。

The summary is that it's not possible to request this permission on Android Wear 1.x, but it is on Wear 2 (currently in beta and slated for release in early 2017). 摘要是，无法在Android Wear 1.x上请求此权限，但在Wear 2（当前为Beta版，计划于2017年初发布）上进行请求。

In addition to @String's answer, you might want to use requestPermissions() method. 除了@String的答案，您可能还想使用requestPermissions()方法。 Please note, these permissions must be requested in your manifest. 请注意，必须在您的清单中请求这些权限。

And, as mentioned in Permissions for Services , 而且，如“服务许可”中所述，

only an activity can call the requestPermissions() method, so if the user interacts with your app via a service, for example a watch face, the service must open a background activity before requesting the permission. 只有活动可以调用requestPermissions()方法，因此，如果用户通过服务（例如表盘）与您的应用进行交互，则该服务必须在请求权限之前打开后台活动。
