About arrayAdapter

Question

I have in my app a ListView with adapter, I use this to show a list with a chechbox and a textView

public class MyListAdapter extends ArrayAdapter<Model> {
    private LayoutInflater inflater;
    private int position;

    public int getPosition() {
        return position;
    }

    public void setPosition(int position) {
        this.position = position;
    }

    public MyListAdapter (Context context, List<Model> listMeasurement){
        super(context, R.layout.simplerow, R.id.empty, listMeasurement);
        inflater= LayoutInflater.from(context);
    }

    public View getView(int position, View convertView, ViewGroup parent){
        Model model= (Model)this.getItem(position);
        CheckBox checkBox;
        TextView textView;
    }
}

My question is:

I want to show another list in another activity, this will have an image, two textViews and a button. The image depends on the value of the textView.

The best way to do this is do other ArrayAdapter? or use other things?

Thanks in advance.

You need to extend the BaseAdapter and override the getView() method. Here is a sample.

    private class CustomAdapter extends BaseAdapter {

        private LayoutInflater inflater;
        private ArrayList<Model> list;

        public CustomAdapter(Context context, ArrayList<Model> list) {
            this.inflater = LayoutInflater.from(context);
                        this.list = list;
        }

        @Override
        public int getCount() {
                    return list.size();
        }

        @Override
        public Object getItem(int position) {
           return list.get(position);
        }

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

        @Override
        public View getView(int position, View view, ViewGroup parent) {

            // If the view is null inflate it from xml
            if (view == null)
                view = inflater.inflate(R.layout.list_row, null);

            // Bind xml to java
           ImageView icon = (ImageView) view
                .findViewById(R.id.image);
           TextView text = (TextView) view.findViewById(R.id.text);
                       text.setText(list.get(position).getText());
                       icon.setImageDrawable(list.get(position).getDrawable());

           return view;
       }

   }
