[android-developers] Re: ListView update problem.

Hi Boston,
Thanks for your time.

Yes, i modify the values of the vectors, but not the size of the
vector. And after modifying my values, I call
adapter.notifyDataSetChanged();

Initially, the size of the ListView is 6 and the size of all the
Vectors is 5.

in getView() i write as below

if(position == 0){
holder.textView1.setText("Label1");
holder.textView2.setText("Label2");
holder.textView3.setText("label3");
}else{
holder.textView1.setText(vector1(position-1));
holder.textView2.setText(vector2(position-1));
holder.textView3.setText(vector3(position-1));
}

int getCount(){
return vector1.size() + 1;
}
Is adapter.notifyDataSetChanged() enough to reflect the changes?? Or i
have to set listView.setAdapter(adapter) again...

When i remove the below condition in getView(...)
if(position == 0){// apply different color to the row }else{// some
other code..}

It works well...
Its a mystery... :)
