Question

I am implementing a ListFragment using a custom ArrayAdapter to populate the list. Each row item has an ImageView and three TextViews. Data is being parsed via XML and the i

Answer 1

In my case revert back was forgotten in if else condition:

/*public class ContactAdapter extends BaseAdapter {
    public List _data;
    private ArrayList arraylist;
    Context _c;
    ViewHolder holder;

public ContactAdapter(List contacts, Context context) {
    _data = contacts;
    _c = context;
    this.arraylist = new ArrayList();
    this.arraylist.addAll(_data);
}*/
@Override
public View getView(final int i,  View convertView, final ViewGroup viewGroup) {
    View view = convertView;
    final Contact data = (Contact) _data.get(i);
    ViewHolder holder ;

    if (view == null) {
        Context context = viewGroup.getContext();
        LayoutInflater inflater = LayoutInflater.from(context);
        view = inflater.inflate(R.layout.contact_list, null,false);
        holder = new ViewHolder();
        holder.title = (TextView) view.findViewById(R.id.name);
        holder.imageView = (ImageView) view.findViewById(R.id.pic);
        view.setTag(holder);
    } else {
        holder = (ViewHolder) view.getTag();
    }

    holder.title.setText(data.getName());
    // Set image if is null string
    if(!data.getThumb().equals("null")){
        try {
             Bitmap myBitmap = BitmapFactory.decodeFile(ImageStorage.getImage(data.getThumb()).getAbsolutePath());
             holder.imageView.setImageBitmap(myBitmap);
            }catch (Exception e){e.printStackTrace();
             holder.imageView.setImageResource(R.mipmap.contactimage);
          }

    }else // I had forgotten this else 
        holder.imageView.setImageResource(R.mipmap.contactimage); 


    // same action with background color
    if(data.getId()==data.getFromContact() ){
         view.setBackgroundColor(Color.RED);
     } else{
         view.setBackgroundColor(Color.WHITE); //**revert back it**
     }
        return view;
}

ViewHolder

  private  static class ViewHolder {
    ImageView imageView;
    TextView title;

}
