How do we pass different value to another activity by selecting choice-based table row in a table

I have created a table containing dynamic table rows. Each table row contain 5 textview containing data's like region name ,regioncode ,target etc. I have implemented a table row OnclickListner,So a user can select the table row to view more specific data in another activity. The problem is each table row Contain must diffrent regionCode to be passed to another activity. How could we pass this to another activity.I tried using string array but it show null point exception.
This is my code
// IF BRANCHFLAG IS ZONAL
else if(branchFlag.equals("Z"))
{
final List<NameValuePair> details = new ArrayList<NameValuePair>(1);
details.add(new BasicNameValuePair("branchCode", branchCode));
details.add(new BasicNameValuePair("branchFlag", branchFlag));
details.add(new BasicNameValuePair("finYr",finyear));
details.add(new BasicNameValuePair("month", month_number));
Log.d("month_num", month_number);
response = apc.postURL(RETRIEVE_BRANCH_MIS_DETAILS_LINK, details);
Log.d("**************", RETRIEVE_BRANCH_MIS_DETAILS_LINK + details);
Log.d("RETRIEVE_MainMis_DETAILS_LINK", response);
try {
JSONObject jsonObject = new JSONObject(response);
jsonArray = jsonObject.getJSONArray("result");
errorflag = jsonObject.getString("errorFlag");
errormsg = jsonObject.getString("errorMsg");
if (errorflag.equals("N"))
{

}
}

The simplest way to do this is like this
Intent intent = new Intent(MainMis.this, RegionMIS.class);
intent.putExtra("EXTRA_REGION_CODE", regionCode);
startActivity(intent)

I got the answer.. i created one more textview with its visiblity as GONE
textArray[i] = new TextView(MainMis.this);
textArray[i].setId(i + 111);
textArray[i].setText(String.valueOf(regionBrCode));
textArray[i].setTextColor(Color.BLACK);
// textArray[i].setWidth(10);
textArray[i].setPadding(5, 5, 5, 5);
textArray[i].setGravity(5);
textArray[i].setVisibility(View.GONE);
tr_head1[i].addView(textArray[i]);
Then i added this in onClick listner of the table row
{
#Override
public void onClick(View v)
{
v.setBackgroundColor(Color.RED);
String t=String.valueOf(v.getId());
Log.d("ROW CLICKED : ",t);
// get the table clicked
TableRow tablerow = (TableRow)tl.getChildAt(v.getId());
TextView sample = (TextView) tablerow.getChildAt(5);
String result=sample.getText().toString();
Log.d("RegionCode",result);
Intent a=new Intent(MainMis.this,RegionMIS.class);
a.putExtra("regionCode",result);
}
});

Horizontally scrolling in not working in android

In my following code horizontal scrolling is not working while displaying the data but vertically it's working properly. This java code is working properly if the data is in only one screen but if the data is out of screen, it hides, i'm not able to find out the problem. I used scrollview for scrolling, tablelayout and textview. Please help me :

how to put the heading after the header() in android

hi in the below I am fetching the data from database and getting the json response and displaying in an android table layout.But everything was working fine but i want to put some sub headings for displaying data for that I took the textview In that using setText() I am giving sub heading.But it's not displaying proper heading.
this output when I am running my app:
General registration
SI Date Toatal Registration
1 2015-04-01 2
2 2015-04-02 3
1 2015-04-02 3
Expected output:
SI Date Toatal Registration
General registration
1 2015-04-01 2
2 2015-04-02 3
Ipd registration
1 2015-04-02 3
