ContentLoadingProgressBar never shows

Question

I've replaced in my fragment simple ProgressBar with ContentLoadingProgressBar. Now fragment layout looks like this:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
            style="@style/simple_match_parent_style">

<android.support.v4.widget.ContentLoadingProgressBar
            android:id="@+id/progress"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_centerInParent="true"/>

<TextView
    android:id="@+id/txt_no_songs"
    android:text="@string/txt_no_songs"
    android:layout_centerInParent="true"
    style="@style/txt_no_songs"/>

<ListView
    android:id="@+id/list"
    android:fastScrollEnabled="true"
    android:divider="@null"
    style="@style/simple_match_parent_style"/>

</RelativeLayout>

I show this ProgressBar in onViewCreated:

@Override
public void onViewCreated(View view, Bundle savedInstanceState) {
    super.onViewCreated(view, savedInstanceState);
    progressBar = (ContentLoadingProgressBar) view.findViewById(R.id.progress);
    progressBar.show();
    ...
}

For test purpose I've removed progressBar.hide() call to make ProgressBar appear in any case. But the problem is that my ContentLoadingProgressBar is never really shown.

Should I do something else to show ContentLoadingProgressBar? I didn't manage to find any relevant examples of using ContentLoadingProgressBar so any useful examples are also desirable. Thanks in advance.

Seems you need a style, for example...

style="?android:attr/android:progressBarStyleHorizontal"

Works for me if I put that anyway, without I never see anything.

Also consider putting it above your content (ie below in the xml)
