Android: Get activity context into array adapter class

I am trying to make a glass breaking effect on a tinder like cardstack. The cards are working fine but I am having trouble getting the activity contextinto the adapter so I can use the brokenview plugin.

I have my mainactivity, on that activity I show a fragment and on that fragment I display the cardstack.

On that card stack I want to show a glass breaking animation when a user clicks a low rating button using this library:

So in my adapter getview I set the context for the broken view with the context with this line:

mBrokenView = BrokenView.add2Window((MainActivity)this.getContext());

But when I run click on the button I am getting this error:

ClassCastException: com.mysampleapp.Application cannot be cast to com.mysampleapp.MainActivity

Thank you for your help.

Full code below:

public class SongPreviewCardsDataAdapter extends ArrayAdapter<SongDatabaseMappingAdapter> {

    public SongPreviewCardsDataAdapter(Context context, int resource) {
        super(context, resource);

    }

    ImageButton oneStarRating;
    BrokenView mBrokenView;
    private BrokenTouchListener listener;

    @Override
    public View getView(int position, final View contentView, ViewGroup parent) {

       // Initialise Song Views
       final SongDatabaseMappingAdapter item = getItem(position);

       TextView songName = (TextView) (contentView.findViewById(R.id.songNameTextView));
       songName.setText(item.getSongTitle());

       // Initialise  Rating Buttons
        oneStarRating = (ImageButton) contentView.findViewById(R.id.ratingButton1);
        if (item.getOneStarRating()) {
            oneStarRating.setImageResource(R.drawable.starfull);

            mBrokenView = BrokenView.add2Window((MainActivity)this.getContext());
            listener = new BrokenTouchListener.Builder(mBrokenView).build();
            songName.setOnTouchListener(listener);

        }
