This is my Main Method Code

this.context = context;
prefManager = new PrefManager(context);
}
@Override

View view= LayoutInflater.from(parent.getContext()).inflate(R.layout.frieght_wiseadapterlayout,parent,false);
return new FreightAdapter.ViewHolder(view);
}
@Override
public void onBindViewHolder(FreightAdapter.ViewHolder holder, int position) {
final dialogPOJO lenaDenaPOJO = list_data.get(position);
if (position %2 == 1){
holder.linearLayout_data.setBackgroundColor(context.getResources().getColor(R.color.white));
}else {
holder.linearLayout_data.setBackgroundColor(context.getResources().getColor(R.color.colorGrey));
}
String countString = lenaDenaPOJO.getCount();
holder.ordernumber.setText( countString );
holder.ordernumber1.setText( lenaDenaPOJO.getKey());
String truck_id = lenaDenaPOJO.getReports();
