片段中未调用onRequestPermissionsResult

Question

在请求Fragment中的权限时，我目前遇到问题。要求位置权限时，未调用我片段中的onRequestPermissions方法。

这里是我的代码。

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
        if (activity?.checkSelfPermission(Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_DENIED) {
            requestLocationPermission()
            permissionNeededLayout.visibility = View.VISIBLE
        }
        if (activity?.checkSelfPermission(Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED) {              
            permissionNeededLayout.visibility = View.GONE
            permissionDeniedLayout.visibility = View.GONE
        }
    } else {
            //TODO
    }

 private fun requestLocationPermission() {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
        val shouldProvideRationale = shouldShowRequestPermissionRationale(Manifest.permission.ACCESS_FINE_LOCATION)

        if (shouldProvideRationale) {
            //TODO show need location fragment
            Log.d("ProductListFragment", "Displaying permission rationale to provide additional context.")
                requestPermissions(arrayOf(Manifest.permission.ACCESS_FINE_LOCATION), LOCATION_PERMISSION_REQUEST)
        } else {
            Log.d("ProductListFragment", "Not displaying rational")
            requestPermissions(arrayOf(Manifest.permission.ACCESS_FINE_LOCATION), LOCATION_PERMISSION_REQUEST)
        }
    }

}

override fun onRequestPermissionsResult(requestCode: Int, permissions: Array<String>, grantResults: IntArray) {
    super.onRequestPermissionsResult(requestCode, permissions, grantResults)
    Log.d(TAG,"onRequestPermissionsResult")
    if (requestCode == LOCATION_PERMISSION_REQUEST) {
        Log.d(TAG,"result = result location")
        when {
            // If user interaction was interrupted, the permission request is cancelled and you
            // receive empty arrays.
            grantResults.isEmpty() -> Log.d(TAG, "on result User interaction was cancelled.")
            //Permission granted.
            (grantResults[0] == PackageManager.PERMISSION_GRANTED) -> Log.d(TAG,"on result permission granted, get location")
            // Permission denied.
            // Additionally, it is important to remember that a permission might have been
            // rejected without asking the user for permission (device policy or "Never ask
            // again" prompts). Therefore, a user interface affordance is typically implemented
            // when permissions are denied. Otherwise, your app could appear unresponsive to
            // touches or interactions which have required permissions.
            (grantResults[0] == PackageManager.PERMISSION_DENIED) -> Log.d(TAG,"on result permission denied")
            else -> Log.d(TAG,"grantResult ${grantResults.size}")
        }
        Log.d(TAG,"onPermisionResult no location request code")
    }
}

似乎创建了我创建片段的Activity的onRequestPermissions方法，而不是调用了being方法。我想念什么吗？我在做什么错了？
