Android - Creating Listview using Custom Adapter Programmatically

I'm in learning about add view programmatically. But, I'm in confusing now.
I have data, there are idpatient, idheader. Patient can have more than one ID header. When I input idpatient, it will add listview (with custom adapter) programmatically. The number of listview is same with the number of ID header.
I want to set in each listview with data patient group by ID header..
So far, I add search view when loop adding listview, but when I input one ID header to seacrh view, all of listview will view the same data according to ID header in search view..
I'm sorry for the long explanation. Can anybody help me to solve this problem?
Thanks in advance

When you add any extra in your intent, don't try to get it from the Bundle. So change your reading passed data code to:
Intent intent = getIntent();
String getName = intent.getStringExtra("one", "default_value_if_null");
textView.setText(getName);

change your code like this
Intent intent = getIntent();
if(intent != null)
{
String getName = intent.getExtras().getString("one");
textView.setText(getName);

Problem
First item in the list maps to 5th item. 2nd item to sixth item. I mean if I change radio button at the first item, Same radio button gets selected at the 5th list item also.
Any suggestions?
Is it because of recycling?
How do I resolve it?
I tried saving in Question object and retrieving it. I used pos to retrieve and set. But same problem still exist.
