Java onRequestPermissionsResult（）的问题

我可以在我的片段中授予或拒绝权限，但当权限被授予但似乎没有被调用时，我尝试调用一个方法

public final int MY_PERMISSIONS_REQUEST_COARSE_LOCATION = 1;

In onCreateView（）：（这很有效）

当从对话框授予权限时，不会调用retrieveGyms（），但会授予权限。

@Override
    public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) {
        switch (requestCode) {
            case MY_PERMISSIONS_REQUEST_COARSE_LOCATION: {
                if (permissions.length == 1 && permissions[0] == Manifest.permission.ACCESS_COARSE_LOCATION && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                    retrieveGyms();
                } else {
                    // Location permission denied.
                }
            }
        }
    }

显示retrieveGyms（）只是为了显示它的功能和我的期望

public void retrieveGyms() {
        AsyncHttpClient client = new AsyncHttpClient();
        client.get("https://gyminyapp.azurewebsites.net/api/Gym", null, new JsonHttpResponseHandler() {
            @Override
            public void onSuccess(int statusCode, Header[] headers, JSONArray response) {
                gymsArray = response;

                // HashMap<String, Object> returnedGyms = new HashMap<String, Object>();
                for (int i = 0; i < gymsArray.length(); i++) {
                    try {
                        // TODO: check distance from current user location and remove if not within search radius

                        String latitude = gymsArray.getJSONObject(i).getString("latitude");
                        String longitude = gymsArray.getJSONObject(i).getString("longitude");
                        Double doubleLat = Double.parseDouble(latitude);
                        Double doubleLong = Double.parseDouble(longitude);

                                .snippet(addressString)
                                .position(gymCoord));
