second create cropoptionadapte.java


public class CropOptionAdapter extends ArrayAdapter<CropOption> {

if (item != null) {

((TextView) convertView.findViewById(R.id.tv_name)).setText(item.title);

return convertView;
}

return null;
}

}

third create CropOption.java

import android.content.Intent;
import android.graphics.drawable.Drawable;

public class CropOption {
public CharSequence title;
public Drawable icon;
public Intent appIntent;
}

create main.xml file

<?xml version="1.0" encoding="utf-8"?>

create crop_selector.xml file
