Android Kotlin 上未授予位置

Question

即使我允许在虚拟电话内访问位置，它仍然停留在“您需要授予访问位置的权限”。

override fun onRequestPermissionsResult(
        requestCode: Int, permissions: Array<out String>, grantResults: IntArray
    ) {
        super.onRequestPermissionsResult(requestCode, permissions, grantResults)
        when (requestCode) {
            1000 -> {
                if (grantResults.isNotEmpty() &&
                    grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                    // permission granted
                } else {
                    // permission denied
                    Toast.makeText(this, "You need to grant permission to access location",
                        Toast.LENGTH_SHORT).show()
                }
            }
        }
    }

有什么想法吗？

Api 级别 31 的位置权限有点不同。
API 级别 31 的位置权限

您可以使用名为 EasyPermissions 让您的生活更轻松。

@AfterPermissionGranted(REQUEST_LOCATION_PERMISSION)
    public void requestLocationPermission() {
        String[] perms = {Manifest.permission.ACCESS_FINE_LOCATION};
        if(EasyPermissions.hasPermissions(this, perms)) {
            Toast.makeText(this, "Permission already granted", Toast.LENGTH_SHORT).show();
        }
        else {
            EasyPermissions.requestPermissions(this, "Please grant the location permission", REQUEST_LOCATION_PERMISSION, perms);
        }
    }
