Good Day

I'm trying to capture an image with camera when I press the Button,then save it in Sqllite and then display it in gridview.. but after I capture the image it doesn't appear in the grid view :/ can anyone help?

here is my code

public class CameraFragment extends Fragment {

    public static final int MEDIA_TYPE_IMAGE = 1;
    private static final int CAMERA_CAPTURE_IMAGE_REQUEST_CODE = 100;
    private static final String IMAGE_DIRECTORY_NAME = "Myfiles";// directory name to store captured images
    private static String mCurrentPhotoPath;  // file path to the last image captured
    View view;
    private Uri fileUri;// file url to store image
    private GridView myGridView;
    private ImageListAdapter adapter;
    private List<Images> myLists;// image list
    Images images;
    DatabaseAdapter DBadapter;


    @Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {

        if (view != null) {
            ViewGroup parent = (ViewGroup) view.getParent();
            if (parent != null)
                parent.removeView(view);
        }
        try {
            // Inflate the layout for this fragment
            view = inflater
                    .inflate(R.layout.fragment_camera, container, false);


        } catch (InflateException e) {
            /* map is already there, just return view as it is */
            e.printStackTrace();
        }
        if (view != null)
            init();
        return view;

    }
