ListView error after scrolling
I have an A ListView
to display some questions in my application. When mine is ListView
displayed for the first time before I scroll, everything looks correct, until I scroll down and scroll up in ListView
mine, multiple views in the list from mine ListView
change like this:
1. ListView before Scroll
2.ListView After Fisrt Scroll
3. ListView After next Scroll
I have no idea why this is happening to mine ListView
, I have searched for many solutions, but it seems to me it doesn’t help me, this is my code for calling my adapter:
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inisialisasi layout utama
kuisioner = inflater.inflate(R.layout.new_quisioner, container, false);
//ListView
list_tt = (ListView)kuisioner.findViewById(R.id.list_tt);
//list
listQuisioner = new ArrayList<ModelListQues>();
lisLabelQues = new ArrayList<ModelLabelQues>();
me=((ModelESPAJ)getActivity().getApplication());
helper=new DBSpaj(getActivity());
onLoadList();
Adapter_Quisioner adapter_Quisioner = new Adapter_Quisioner(getActivity(), listQuisioner, lisLabelQues);
if(list_tt.getCount()!=listQuisioner.size()){
list_tt.setAdapter(adapter_Quisioner);
}
return kuisioner;
}
This code to install my adapter:
public class Adapter_Quisioner extends BaseAdapter{
Context context;
int count;
ArrayList <ModelListQues>listQuisioner;
ArrayList <ModelLabelQues>lisLabelQues;
public Adapter_Quisioner(Context context, ArrayList <ModelListQues>listQuisioner, ArrayList <ModelLabelQues>lisLabelQues){
this.context = context;
this.listQuisioner = listQuisioner;
this.lisLabelQues = lisLabelQues;
this.count=listQuisioner.size();
}
@Override

return count;

@Override

if(view == null){
## don't make any view GONE here
}else{
}
## Play with visibility or GONE for every view here.This will solve your problem
holder.option_label_y_tt3.setVisibility(View.GONE);
holder.option_label_y_tt2.setVisibility(View.GONE);
holder.option_label_y_tt1.setVisibility(View.GONE); and more...
Then rest of your code
