Implementing the LoadingFragment is just like a regular fragment. Management of the progress bar is done completely behind the scenes as your View is programatically injected into the structured view hierarchy.
LoadingFragment has three abstract methods:
public abstract View onCreateMainView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState);
public abstract void configureAnimator(ViewAnimator viewAnimator);
public abstract void configureProgressBackground(ImageView mProgressBBackground);onCreateMainView is identical to onCreateView of a standard fragment. The other two methods provide access to the indeterminate progress bar background, and the managing ViewAnimator.
There are two public methods:
showContent()
showLoading()The starting screen is the progress bar, after your content is done loading simply call showContent(). If you need to reload your view's data, call showLoading() first if desired.
