当用户允许权限时，我在 onRequestPermissionsResult 中放入权限授予的函数没有调用

Question

在这个应用程序中，我将在整个应用程序中请求 2 个权限 1) 当前位置 2) 在应用程序打开对话框获取权限和用户允许权限时调用，然后任务将完成在 onRequestPermissionsResult

中授予的权限

当用户点击呼叫时，呼叫对话框打开，当用户允许呼叫权限时，不拨打电话，用户再次点击呼叫，现在应用程序拨打电话

所以我的问题是当用户允许权限但没有调用我在 onRequestPermissionsResult

中授予权限的函数

地图片段

在这个片段中，我请求当前位置权限，当用户允许时，然后调用 getlastlocation 函数，但 getlastlocation 函数在允许权限后没有调用

所以请给一些建议问题是用户允许权限但没有执行用户允许权限时应该完成的任务

Answer 1

您正在使用

ActivityCompat.requestPermissions(
            (Activity) MapFragment.super.getContext(),
            new String[] { Manifest.permission.ACCESS_FINE_LOCATION },
            REQ_PERMISSION
    );

而不是

requestPermissions(new String[] { Manifest.permission.ACCESS_FINE_LOCATION },REQ_PERMISSION );

当您使用 ActivityCompat.requestPermissions 时，它将在包含片段的 Activity 中为您提供结果。因此，您应该直接使用 requestPermissions 来获取片段中的回调。

当用户允许权限时，我在 onRequestPermissionsResult 中放入权限授予的函数没有调用

when user allow the permission then the function which i put in permission grant in onRequestPermissionsResult didn't call

permissions

android

google-maps

call

currentlocation
