Looks that the element.get(0) is the problem. I assume not all items in your adapter contains the img property. You should check if the img exists before getting it.

Your activity should implement *WorkoutListListener* interface and override its method itemClicked().
public class MainActivity extends AppCompatActivity implements WorkoutListListener {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
#Override
public void itemClicked(long id){
// handle your click here
}
}

I don´t see any reason why thumbPath needs to be an field of SDVideos, it is only used inside VideoListAdapter.getView.
Your updated code of moving thumbPath as a variable would be the following:
int videoId = videoCursor.getInt(videoCursor.getColumnIndexOrThrow(MediaStore.Video.Media._ID));
Cursor videoThumbnailCursor =getContentResolver().query(MediaStore.Video.Thumbnails.EXTERNAL_CONTENT_URI,
thumbColumns, MediaStore.Video.Thumbnails.VIDEO_ID+ "=" + videoId, null, null);
if (videoThumbnailCursor.moveToFirst())
{
String thumbPath = videoThumbnailCursor.getString(videoThumbnailCursor.getColumnIndex(MediaStore.Video.Thumbnails.DATA));
Log.i("ThumbPath: ",thumbPath);
thumbImage.setImageURI(Uri.parse(thumbPath));
}
return listItemRow;
Since the thumbPath will only be populated if the cursor have any data, you can move the setImageURI to inside your if.
This code will solve the NullPointerException, but probably you will not see any image in the thumbImage.
Now you need to find why your videoThumbnailCursor is returning no data. After you find why, please update your question.

This is my code for the RecyclerFrame, in here you can see cPoints.add(jsonObject.getInt("charging_capacity")); I want to display this inside the RecyclerViewer, now I can only display the names array.
This is my RecyclerAdapter code:

mCardView = (CardView) v.findViewById(R.id.card_view);
mTextView = (TextView) v.findViewById(R.id.tv_blah);

mImageView = (ImageView) v.findViewById(R.id.imageView1);
}
}
public RecycleAdapter(ArrayList<String> names, ArrayList<Integer> cPoints){
ArrayDataset = names;
ArrayDataset2= cPoints;
}
#Override
public RecycleAdapter.MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType){
View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.fragment_card_view, parent, false);
MyViewHolder vh = new MyViewHolder(v);
return vh;
}
#Override
public void onBindViewHolder(MyViewHolder holder, int position){
holder.mTextView.setText(ArrayDataset.get(position));
holder.mTextView2.setText(ArrayDataset2.get(position));
holder.mImageView.setImageResource(R.drawable.ic_local_parking_black_24dp);
}
#Override
public int getItemCount() { return ArrayDataset.size(); }
}
I know the changes need to be made here but I don't know how to. I've read some about a DataSet class but I don't know how to implement it. Could anyone tell me how I can add multiple arrays to the recyclerview?

Replace these
ArrayList<String> names = new ArrayList<>();
ArrayList<Integer> cPoints = new ArrayList<>();
With something like this
static class Point {
String name;
int points;
}
List<Point> points = new ArrayList<>();
And make your RecyclerView use the Point class instead of needing more than one list.
private List<Point> mPoints;
public RecycleAdapter(List<Point> points){
mPoints = points;
}
Ideally, you would use Gson to create Java objects directly from your JSON.

Update the RecycleAdapter to take List cPoints as the argument and just pass the cPoints as the parameter to RecycleAdapter and update the code as below
List<Integer> point;
public RecycleAdapter(ArrayList<String> names,List<Interger> cPoint){
ArrayDataset = names;
point=cPoint
}
If you want you can use the existing Text view which is in the layout or add another one to show the charging point

Error Inflating New Fragment

Summary: MainActivityFragment passes passes an intent to DetailedActivity when an item is clicked to display detailed data. Since I want to display these within a Two-Pane interface, I needed to make the DetailedActivity a fragment.
Problem : Whenever clicking on the item in MainActivityFragment to launch the intent for DetailedActivityFragment, I get an error saying its unable to start or inflate the activity. The detailedActivity for sake here is named "test" and "testFragment". It appears as though it points to line 25 of the activity_test.xml which is the line of include layout="#...".
I have left the fragment_test.xml out due to its length but i will provide a github link to anyone whom may want to see it or the manifest.
Im currently a novice to the android world so any help is appriciated =)! This branch of my project is a huge mess right now experimenting with things right now so pardon the mess...

make sure to use:
import android.support.v4.app.Fragment;
And also make sure that the Activity that is using the fragment(s) extends FragmentActivity instead of the regular Activity,
import android.support.v4.app.FragmentActivity;
to get the FragmentActivity class.

One think I found is add app:layout_behaviour to include tag and not inside content_test.xml
<include layout="#layout/content_test"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
/>
And your project got many NPE unable to test more.
