Question

I have a list view whose adapter is in a different class in a different package. Now I have to get the data from database then I set Adapter for my list view using this data. So I have created an ArryList and pass this in the constructor of Adapter while seeting it for the list view. But the problem is that the data is repeating. eg.- there are 12 distinct Strings in the arraylist but what I get is -first five elements in order and after that the same five are being repeated. The count of data is always right but the position will always be 0,1,2,3,4 . I can not understand what the problem is . here is the code –

public class CheckboxAdapter extends BaseAdapter{

    LayoutInflater inflater ;
    ArrayList<String> mData = new ArrayList<String>();

    //constructor for lesion adapter
    public CheckboxAdapter (Context context, ArrayList<String> data){
        inflater = LayoutInflater.from(context);
        mData = data;
    }

    @Override
    public int getCount() {
        // TODO Auto-generated method stub
        return mData.size();
    }

    @Override
    public Object getItem(int position) {
        // TODO Auto-generated method stub
        return position;
    }

    @Override
    public long getItemId(int position) {
        // TODO Auto-generated method stub
        return position;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        if (convertView == null){
            Log.v("pos", ""+position);
            convertView = inflater.inflate(R.layout.e_lesion_liststyle, null);          
            final CheckBox cb = (CheckBox) convertView.findViewById(R.id.disease_lesion_checkbox);
            cb.setText(mData.get(position));
            cb.setOnClickListener(new OnClickListener() {           
                @Override
                public void onClick(final View v) {
                    cb.setButtonDrawable(R.drawable.check_box_1);
                }
            });
        }//end of if condition
        return convertView;
    }

try this.. just write all code out of the condition expect inflate code..

@Override
    public View getView(int position, View convertView, ViewGroup parent) {
        if (convertView == null){
            Log.v("pos", ""+position);
            convertView = inflater.inflate(R.layout.e_lesion_liststyle, null);   
           }       //end of if condition
            final CheckBox cb = (CheckBox) convertView.findViewById(R.id.disease_lesion_checkbox);
            cb.setText(mData.get(position));
            cb.setOnClickListener(new OnClickListener() {           
                @Override
                public void onClick(final View v) {
                    cb.setButtonDrawable(R.drawable.check_box_1);
                }
            });

        return convertView;
    }
