-----------------------------------------------------

    SignUp.this.findViewById(R.id.progress_bar).setVisibility(View.VISIBLE);
            Call<UploadPhoto> call = apiService.uploadFile(fileToUpload, filename, api, user_email);

            call.enqueue(new Callback<UploadPhoto>() {
                @Override
                public void onResponse(Call<UploadPhoto> call, Response<UploadPhoto> response) {
                    SignUp.this.findViewById(R.id.progress_bar).setVisibility(View.GONE);
                    UploadPhoto inquiryResponse = response.body();
                    if (inquiryResponse.getStatus().equals("1")) {

                    } else {
                    }
                }

                @Override
                public void onFailure(Call<UploadPhoto> call, Throwable t) {
                }
            });


    -----------------------------------------------------------
    and then creat xml file : >> progress_uploading_layout.xml
    --------------------------------------------------------------------
    <?xml version="1.0" encoding="utf-8"?>
    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/progress_bar"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:gravity="center"
        android:visibility="gone"
        android:background="@android:color/transparent"
        android:orientation="vertical">

        <ProgressBar
            android:layout_width="wrap_content"
            android:layout_height="wrap_content" />

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="@string/uploading"
            android:textColor="@color/green"
            android:textSize="20sp" />
