My ListView
contains two Textviews
. In one row first one is for name and second one is for result. I need to change the background color of the result TextView
according to the result. Like if pass then the result TextView
color will be green when fails result TextView
color will be red.I have ten rows in my ListView
. I have tried like this
@Override
public View getView(int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
ViewHolder holder;
if(convertView==null)
{
holder = new ViewHolder();
convertView = inflater.inflate(R.layout.items, null);
holder.imgViewLogo = (ImageView) convertView.findViewById(R.id.imgViewLogo);
holder.txtViewTitle = (TextView) convertView.findViewById(R.id.txtViewTitle);
holder.txtViewDescription = (TextView) convertView.findViewById(R.id.txtViewDescription);
holder.txtholder = (TextView) convertView.findViewById(R.id.holder1);
holder.img = (ImageView) convertView.findViewById(R.id.temperrr);
convertView.setTag(holder);
}
else
holder=(ViewHolder)convertView.getTag();
ItemBean bean = (ItemBean) itemList.get(position);
holder.imgViewLogo.setImageResource(bean.getImage());
holder.txtViewTitle.setText(bean.getTitle());
holder.txtViewDescription.setText(bean.getDescription());
//------------------
if (position==0)
{
if(GridviewAdapter.glu>=81)
{
holder.img.setImageResource(R.drawable.red_arrow);
holder.txtViewDescription.setBackgroundResource(R.color.resultred);
holder.txtholder.setBackgroundResource(R.color.resultred);
}
else if (GridviewAdapter.glu==79||GridviewAdapter.glu==80)
{
holder.img.setImageResource(R.drawable.orange_arrow);
holder.txtViewDescription.setBackgroundResource(R.color.resultoren);
holder.txtholder.setBackgroundResource(R.color.resultoren);
}
else
{
holder.img.setImageResource(R.drawable.resultarrawnocolor);
holder.txtViewDescription.setBackgroundResource(0);
holder.txtholder.setBackgroundResource(0);
}
}
holder.img.setImageResource(R.drawable.resultarrawnocolor);
return convertView;
}
But, when scrolling the list the another random items's background color changing.what I have to do .? How can I control the items at each position in the listview . The above code is for just for the first row. am I right?

I think it is because list view recycles the view hence causing such problems .Try the following :
Since convert view and row view both are intialized as null .Hence rows will be inflated every time and preventing recycling of views .
