Android Android Activity Lifecycle The Project Creating the Adapter

android.content.res.Resources$NotFoundException: String resource ID #0x0

The app is crashing when I try to run it. I think this issue has something to do with the fact that I started out working on this on my own, and thus named my fields different things than you did, but I tried to ferret out a place where I accidentally put your name instead of my own but couldn't find one. Here's my ListAdapter.Java since that seems to be the only class it's erroring on that I had any hand in.

package me.paxana.android.golfscoreapptake2;

import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.Button;
import android.widget.TextView;

/**

public class ListAdapter extends BaseAdapter {

private final Context mContext;
private final HoleScores[] mHoleScores;

public ListAdapter (Context context, HoleScores[] holeScores) {
    mContext = context;
    mHoleScores = holeScores;

}

@Override
public int getCount() {
    return mHoleScores.length;
}

@Override
public Object getItem(int position) {
    return mHoleScores[position];
}

@Override
public long getItemId(int position) {
    return 0;
}

@Override
public View getView(final int position, View convertView, ViewGroup parent) {
    final ViewHolder holder;
    if (convertView == null) {
        convertView = LayoutInflater.from(mContext).inflate(R.layout.list_item, null);
        holder = new ViewHolder();
        holder.holeNumber = (TextView) convertView.findViewById(R.id.holeNumber);
        holder.holeScore = (TextView) convertView.findViewById(R.id.holeScore);
        holder.plusButton = (Button) convertView.findViewById(R.id.plusButton);
        holder.minusButton = (Button) convertView.findViewById(R.id.minusButton);

        convertView.setTag(holder);
    }
    else {
        holder = (ViewHolder) convertView.getTag();
    }

    holder.holeNumber.setText(mHoleScores[position].getLabel());
    holder.holeScore.setText(mHoleScores[position].getHoleScore());
    holder.minusButton.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            int updatedHoleScore = mHoleScores[position].getHoleScore() - 1;
            if (updatedHoleScore < 0) updatedHoleScore = 0;
            mHoleScores[position].setHoleScore(updatedHoleScore);
            holder.holeScore.setText(updatedHoleScore + "");
        }
    });
    holder.plusButton.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            int updatedHoleScore = mHoleScores[position].getHoleScore() + 1;
            mHoleScores[position].setHoleScore(updatedHoleScore);
            holder.holeScore.setText(updatedHoleScore + "");
        }
    });

    return convertView;
}

private static class ViewHolder {
    TextView holeNumber;
    TextView holeScore;
    Button plusButton;
    Button minusButton;
}
}

// if getHoleScore() returns an int, then you'd need to change it to a String first...
    holder.holeScore.setText(mHoleScores[position].getHoleScore());
// to this
   holder.holeScore.setText( Integer.toString(mHoleScores[position].getHoleScore()) );
// or use smushing or your conversion method of choice.

Hi Bryan,

I had this same error pop up. It looks like you (like me) didn't convert the int to a string in the method that was missed at 6:46 of the video, and later fixed 8:54.

More concretely, here at this block of code:

    holder.holeNumber.setText(mHoleScores[position].getLabel());
    holder.holeScore.setText(mHoleScores[position].getHoleScore());
    holder.minusButton.setOnClickListener(new View.OnClickListener() {

        @Override

If you want to follow the same syntax, can change to:

    holder.holeNumber.setText(mHoleScores[position].getLabel());
    holder.holeScore.setText(mHoleScores[position].getHoleScore() + "");
    holder.minusButton.setOnClickListener(new View.OnClickListener() {

        @Override

As Seth pointed out, this would work too:

holder.holeScore.setText( Integer.toString(mHoleScores[position].getHoleScore()) );

Or this:

holder.strokeCount.setText( String.valueOf(mHoleScores[position].getHoleScore())) );

I hope this helps a bit!

Thanks, F
