Glide not loads image from url

I have ListView, where I have ImageView. I need to get the image from url and show in ImageView, but that's not working, the image is not visible. In that ListView I have a TextView and CheckBox too, but you not need it because that works. I'm using Glide. So what's the problem?

I set in glide placeholders and it loads the placeholders. I've done debug and I saw that the glide gets the image URL. But the image doesn't load.

Ok here's the item code.

public class LanguageItem {

String imagePath;

LanguageItem(String imagePath,) {
    this.imagePath = imagePath;
}

public String getImagePath() {
    return imagePath;
}

There are textView and checkbox too, but I'm not showing it to you, because that works fine.

Here the adapter.

public class LanguageAdapter extends BaseAdapter {

private Context context;
private LayoutInflater lInflater;
private ArrayList<LanguageItem> objects;

LanguageAdapter(Context context, ArrayList<LanguageItem> itemObj) {
    this.context = context;
    objects = itemObj;
    lInflater = (LayoutInflater) context
            .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}

//amount of elements
@Override
public int getCount() {
    return objects.size();
}

//element by position
@Override
public Object getItem(int position) {
    return objects.get(position);
}

//id by position
@Override
public long getItemId(int position) {
    return position;
}


@Override
public View getView(int position, View convertView, ViewGroup parent) {

    View view = convertView;
    if (view == null) {
        view = lInflater.inflate(R.layout.language_items, parent, false);
    }

    ImageView imageView = (ImageView) view.findViewById(R.id.imageView);

Glide.with(context).load(objects.get(position).getImagePath()).thumbnail(0.5f).crossFade().into(imageView);


    return view;
}

And here's the fragment. I'm doing my work in fragment.

public class FragmentLanguage extends BaseFragment {

private static final String IMAGE = "IMAGE";
private ApiClient apiClient;
private ArrayList<LanguageItem> objS;
private LanguageAdapter adapter;

private View mainView;
private ListView listView;

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    mainView = inflater.inflate(R.layout.languages, container, false);
    listView = (ListView) mainView.findViewById(R.id.language_list);

    apiClient = ApiClient.getInstance();

    //calling methods
    fillData();
    showResult();

    return mainView;
}

public void fillData() {

    objS = new ArrayList<>();

    getLanguageCall();

}

public void getLanguageCall() {
    Call<ResponseBody> getLanguage = apiClient.getLanguage(SharedPreferencesManager.getInstance().getAccessToken());
    getLanguage.enqueue(new Callback<ResponseBody>() {
        @Override
        public void onResponse(Call<ResponseBody> call, Response<ResponseBody> response) {
            if (response.isSuccessful()) {
                try {
                    String data = response.body().string();
                    JSONArray array = new JSONArray(data);


                    for (int i = 0; i < array.length(); i++) {
                        JSONObject object = array.getJSONObject(i);
                        String languageName = object.getString("name");
                        String path = object.getString("image_path");
                        String real_path = "https://supportop.eu-gb.mybluemix.net" + path.substring(1, path.length());


                        Toast.makeText(context, real_path, Toast.LENGTH_SHORT).show();
                        objS.add(new LanguageItem(languageName,real_path, false));
                    }
                    adapter = new LanguageAdapter(getActivity(), objS);
                    listView.setAdapter(adapter);

                } catch (IOException | JSONException e) {
                    e.printStackTrace();
                }
            } 
        }

        @Override
        public void onFailure(Call<ResponseBody> call, Throwable t) {
            Toast.makeText(context, "Error", Toast.LENGTH_SHORT).show();
        }
    });
}
}

Ok here's the code. I done debug and the Image url it gets successfully, but glide not loads it. Thank you for reading.

Ok and here's the layout.

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="50dp"
android:background="@color/white"
android:orientation="horizontal">

<ImageView
    android:id="@+id/imageView"
    android:layout_width="45dp"
    android:layout_height="30dp"
    android:layout_gravity="center"
    android:layout_marginStart="20dp" />

And here the listView part.

<ListView
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:id="@+id/language_list"
    android:layout_marginTop="10dp"
    android:layout_below="@+id/linearLayout"
    android:layout_above="@+id/bottomNavigationView">

</ListView>
