Play and pause the video player in Fragment#setMenuVisibility:

You can do it one of two ways. 1) declare simple filtergraph for each output, or 2) do all filtering inside a complex filtergraph.

Your DB contains Lists of Genre, Platform, ReleaseDate and Video. SQLite supports column types of INTEGER, REAL, TEXT and BLOB. You must provide methods for conversion of your List types to/from String(TEXT) or one of the other supported SQLite types.

For example:

I'm not going to write the whole code for you but I will show you a better way (imo) to do it:

The Idea is to move api calls out of the hands of RecyclerView or it's Adapter. The view-model or presenter should be responsible for it. so:

1. First add a scroll listener to your view-model( or Activity) which contains the recyclerview:

   recyclerView.addOnScrollListener(...);

2. Next in the scroll listener in the method onScrollStateChanged you check if the newState argument is equal to RecyclerView.SCROLL_STATE_IDLE

3. If yes then you need to find the first completely visible item by calling LinearLayoutManager.findFirstCompletelyVisibleItemPosition()

4. Now you have the index of the visible Item and you can get the information you need from the item in the list and load the video

Note: You need to check for RecyclerView.SCROLL_STATE_DRAGGING in the method I mentioned in step 2 and cancel the call to api respectively.

Because you are new to Android there is a lot wrong. So, many people probably won't want to chime in. Regardless, I'm new as well and in the same class as you are right now, so I'll give it a shot.

First, your loader is not returning the correct data type. Your loader should be of Loader> and it should return a new AsyncTaskLoader>. The reason you want this is to make use of everything the AsyncTaskLoader has to offer. I'll explain further.

Second, we'll cache the data inside the loader by moving the initial reference from the Activity into the loader.

So move private ArrayList mMoviesCollection; as an instance variable of your AsyncTaskLoader. Remove the line mMoviesCollection = new ArrayList(); from both your onCreate and initialize methods.

In your AsyncTaskLoader, you need to check if your data exists already in your onStartLoading before forceLoad and implement deliverResult.

So, your onStartLoading() should look like this:
