public void setContentShownNoAnimation(boolean shown) {
        setContentShown(shown, false);
    }
Like {@link #setContentShown(boolean)}, but no animation is used when
transitioning from the previous state.

@param shown If true, the content view is shown; if false, the progress
             indicator. The initial value is true.
@see #setContentShown(boolean)
