BaseAdapter does not work

Question

I decided to try the to make my own list adapter, I came up with the following code, but the app crashes when opened.

What is wrong?

Thanks in advance!

public class ListAdapter extends BaseAdapter {

    private int [] SexImgArray = {
            R.drawable.sex1,
            R.drawable.sex2,
            R.drawable.sex3,
            R.drawable.sex4,
            R.drawable.sex5,
            R.drawable.sex6,
            R.drawable.sex7,
            R.drawable.sex8,
            R.drawable.sex9,
            R.drawable.sex10,
            R.drawable.sex11,
            R.drawable.sex12,
            R.drawable.sex13,
            R.drawable.sex14,
            R.drawable.sex15,
            R.drawable.sex16,
            R.drawable.sex17,
            R.drawable.sex18,

    };


    private String [] SexTitleArray = {

            "Erotic V",                     //1
            "Fantastic Rocking Horse",      //2
            "Catherine Wheel ",             //3
            "Glowing Triangle",             //4
            "X-Rated",                      //5
            "Nirvana",                      //6
            "Padlock",                      //7
            "Slide",                        //8
            "Ape",                          //9
            "Butterfly",                    //10
            "Ascent to Desire",             //11
            "Balancing Act",                //12
            "Bridge",                       //13
            "Clip",                         //14
            "Double Decker",                //15
            "Seduction",                    //16
            "Crouching Tiger",              //17
            "Hero"                          //18

    };



    Context mContext;

    public ListAdapter(Context context)

    {
        mContext = context;
    }


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

    @Override
    public Object getItem(int position) {
        return null;
    }

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

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        ViewHolder holder;


        if (convertView == null) {
            // brand new
            convertView = LayoutInflater.from(mContext).inflate(R.layout.row_layout, null);
            holder = new ViewHolder();
            holder.ImgView = (ImageView) convertView.findViewById(R.id.ImageView);
            holder.TextView = (TextView) convertView.findViewById(R.id.TextView);

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




        holder.ImgView.setImageResource(SexImgArray[position]);
        holder.TextView.setText(SexTitleArray[position]);


        return convertView;
    }

    private static class ViewHolder {
        ImageView ImgView; // public by default
        TextView TextView;

    }
}

Hi Andre

I have been through your code as I did a very similar class for an app of mine and your code seems to match almost identically, the only real difference being my ViewHolder class is defined only as static where yours is private static so i wonder whether the inner class is being accessed from outside the outer class somewhere by android (only speculation i'm unsure).

What does your LogCat say?

I've attached my working example below just in case you can spot something else

package com.daniel.hartin.mysteryauditor.CustomListViews;


import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.ImageView;
import android.widget.TextView;
import com.daniel.hartin.mysteryauditor.ObjectHolders.Quota;
import com.daniel.hartin.mysteryauditor.R;
import com.daniel.hartin.mysteryauditor.Utilities.QuotaEditor;
import java.util.ArrayList;


public class CustomQuotaView extends BaseAdapter{

    private static ArrayList<Quota> mQuotaList;
    private LayoutInflater mInflater;
    private Context mContext;


    public CustomQuotaView(Context context) {
        mContext = context;
        QuotaEditor editor = new QuotaEditor(context);
        mQuotaList = editor.getQuotaList();
        mInflater = LayoutInflater.from(context);

    }

    public int getCount() {
        return mQuotaList.size();
    }

    public Object getItem(int position) {
        return mQuotaList.get(position);
    }

    public long getItemId(int position) {
        return position;
    }

    public View getView(int position, View convertView, ViewGroup parent) {
        ViewHolder holder;


        if (convertView == null) {
            convertView = mInflater.inflate(R.layout.custom_quota_view, null);
            holder = new ViewHolder();
            holder.serviceName = (TextView) convertView.findViewById(R.id.serviceName);
            holder.totals = (TextView) convertView.findViewById(R.id.totalsValue);
            holder.image = (ImageView) convertView.findViewById(R.id.img);

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


        holder.serviceName.setText(mQuotaList.get(position).getService());
        holder.totals.setText(mQuotaList.get(position).getCompleted() + "/" + mQuotaList.get(position).getTotal());

        if(mQuotaList.get(position).getCompleted() < mQuotaList.get(position).getTotal()) {

            holder.image.setImageResource(R.drawable.red_cross);

        }else {

            holder.image.setImageResource(R.drawable.green_tick);

        }


        return convertView;
    }

    static class ViewHolder {
        TextView serviceName;
        TextView totals;
        ImageView image;
    }

}

Hope this is of some help
