In part 4 of the app widget tutorial, we will learn how to implement adapter-absed views into our home screen widget.
For this we can use a ListView, GridView, AdapterViewFlipper or a StackView.
Since the app widget is in another process, we have to use a RemoteViewsService that returns RemoteViewsFactory objects in it’s onGetViewFactory method as a replacement for a normal adapter. In this class we have to implement onCreate, onDestroy, onDataSetChanged, getCount, getViewAt, getLoadingView, getViewTypeCount, getItemId and hasStableIds, which are similar to the methods of the normal adapter interface.
We set this adapter on our widget with setRemoteAdapter and can additionaly define an empty view that will be displayed if our data set is empty with setEmptyView.
In our manifest file we register our RemoteViewsService with the BIND_REMOTEVIEWS permission that can only be held by the Android system.
With autoAdvanceViewId we can flip through our StackView automatically.

I Adopted Rich People’s Habits, See How My Life ChangedLearn the secrets of success from those who built their own empires from scratch. You can try adopting the habits of super rich people and see how it will help you save money.
Successful people are rarely night owls; they go to bed and wake up quite early. So this was the first habit I decided to take on. By the end of the first week, I noticed that I was able to do way more before noon than I could ever do during the whole day. One more week into the experiment I started waking up completely well-rested and excited to start a new day. Self-made successes swear by exercising every day for at least 30 minutes. After just 10 days, it already became a habit. I became more concentrated and calmer. If meditating helps successful people stay on top of their game, it should help me out too. Networking is like currency for successful people. A lot of successful people (like Steve Jobs, for instance) keep a super minimalistic approach to fashion, often wearing the same outfit every day. Truly smart and successful people control their expenses and don’t spend their money on useless things.
