How do I properly create this custom ArrayAdapter?

Question

I have this code but it doesn't want to work.

also, Main.java line 76 includes this in my onCreate:

setListAdapter(new ImageAndTextAdapter(ctx, R.layout.lchs_item,
    items, icons));

imageandtextadapter.java:

public class ImageAndTextAdapter extends ArrayAdapter<String> {

private LayoutInflater mInflater;

private String[] mStrings;
private TypedArray mIcons;

private int mViewResourceId;

public ImageAndTextAdapter(Context ctx, int viewResourceId,
        String[] strings, TypedArray icons) {
    super(ctx, viewResourceId, strings);

    mInflater = (LayoutInflater)ctx.getSystemService(
            Context.LAYOUT_INFLATER_SERVICE);

    mStrings = strings;
    mIcons = icons;

    mViewResourceId = viewResourceId;
}

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

@Override
public String getItem(int position) {
    return mStrings[position];
}

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

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    convertView = mInflater.inflate(mViewResourceId, null);

    ImageView iv = (ImageView)convertView.findViewById(R.id.item_icon);
    iv.setImageDrawable(mIcons.getDrawable(position));

    TextView tv = (TextView)convertView.findViewById(R.id.item_text);
    tv.setText(mStrings[position]);

    return convertView;
}
    }

if you want more code, just ask. thanks for the help!

EDIT: I added more code. Also, system32 and ebarrenchea's suggestions didn't work. EDIT2: Answered my own question. Solution below

do you think this code will be sufficient to identity your issue...post full code — Pragnani, Feb 16 '13 at 05:36
It was a pretty good start and the OP said would be glad to add more, trying not to do a code dump. I think it was a valid attempt and we should only criticize those that don't even try...just my opinion — codeMagic, Feb 16 '13 at 05:41
in your oncreate you foget `this` here `this.mViewResourceId = mViewResourceId ` — William Kinaan, Feb 16 '13 at 06:45

I've never used holo-everywhere before but it seems your problem is in this line:

02-16 00:19:36.867: E/AndroidRuntime(27101): Caused by: java.lang.ClassCastException: com.android.internal.policy.impl.PhoneLayoutInflater cannot be cast to org.holoeverywhere.LayoutInflater

Your mLayoutInflater should be of type android.view.LayoutInflater, which can be solved with a simple:

import android.view.LayoutInflater;

importing android.view.LayoutInflater rather than org.holoeverywhere.LayoutInflater didn't seem to do anything. — TheWizKid95, Feb 16 '13 at 05:58

looks like i got it guys. I was implementing everything right, I just had the list adapter set wrong on my Main.activity

Edited it from: setListAdapter(new ImageAndTextAdapter(ctx, R.layout.lchs_item, items, icons));

To: this.setListAdapter(new ImageAndTextAdapter(this, R.layout.lchs_item, items, icons));

mInflater = LayoutInflater.from(ctx);
Definitely be HoloEverywere's LayoutInflater.
