How to get data from a xml file into multiple string arrays in android?

Question

Hi I am trying to get information from multiple string arrays held in a xml file to be output in a card view within a recycler view. I am thinking that I access the arrays through the adapter file for the recycler view, however I am not sure as I am new to this.

My xml file is called events.xml and is located in the res/values folder.

My adapter code is this:

public class EventCalenderAdapter extends RecyclerView.Adapter<EventCalenderAdapter.ViewHolder> {

String[] title;
String[] time_start;
String[] time_finish;
String[] date;

static class ViewHolder extends RecyclerView.ViewHolder {
    CardView cardView;
    TextView titleView;
    TextView auxView1;
    TextView auxView2;
    TextView auxView3;

    public ViewHolder(CardView card) {
        super(card);
        cardView = card;
        titleView = (TextView) card.findViewById(R.id.text1);
        auxView1 = (TextView) card.findViewById(R.id.text2);
        auxView2 = (TextView) card.findViewById(R.id.text3);
        auxView3 = (TextView) card.findViewById(R.id.text4);
    }
}

@Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int i) {
    CardView v = (CardView) LayoutInflater.from(parent.getContext()).inflate(R.layout.event_task, parent, false);
    return new ViewHolder(v);
}

@Override
public void onBindViewHolder(ViewHolder viewHolder, final int i) {
    viewHolder.titleView.setText(title[i]);
    viewHolder.auxView1.setText(time_start[i]);
    viewHolder.auxView2.setText(time_finish[i]);
    viewHolder.auxView3.setText(date[i]);

}
@Override
public int getItemCount() {
    return title.length;
}



}

You can ge the string by String[] mydata = getResources.getStringArray(R.array.mystrings);. Then you can pass it to the constructor of the adapter class and use it there. Read developer.android.com/guide/topics/resources/… — Raghunandan

@Raghunandan thank you for your comment however I get an error saying "Cannot resolve symbol 'getResources'" — Nick Fallows

you need to do that in a activity. Activity extends Context and getResources requires context — Raghunandan

the other option is pass the context to the constructor of adapter class. — Raghunandan

You can get your String arrays in constructor:

public EventCalenderAdapter(Context context){
   title= context.getResources().getStringArray(R.array.titleArray);
   //... get the rest of your arrays
}

Then when you instanciate your adapter (new EventCalenderAdapter(YourActivity); ), your arrays will be loaded.

should I put the constructor in the adapter class or the fragment that calls the class, sorry I'm new to this.

my fragment is now not working saying that EventCalenderAdapter(context) cannot be applied

Try with EventCalenderAdapter(getActivity());
