error in following code.......
// Add the TableRow to the TableLayout
tl.addView(tr, new TableLayout.LayoutParams(
LayoutParams.MATCH_PARENT,
LayoutParams.WRAP_CONTENT));

you are parsing JSONArray from your String result, but it is JSONOject so you have to passing like this...
JSONObject jObj = new JSONObject(result);
JSONArray jArray =jObj.getJSONArray("Users");
for (int i = 0; i < jArray.length(); i++) {
JSONObject json_data = jArray.getJSONObject(i);
Users user = new Users();
user.setId(json_data.getInt("id"));
user.setName(json_data.getString("name"));
user.setUsername(json_data.getString("username"));
user.setEmail(json_data.getString("email"));
users.add(user);
}

The way you have added a row into the table layout you can add multiple TableRow instances into your tableLayout object
Try adding multiple rows as in your code you are adding single row multiple times:
Try below code:
void addHeader(){
/** Create a TableRow dynamically **/
tr = new TableRow(this);
/** Creating a TextView to add to the row **/
label = new TextView(this);
label.setText("Name");
label.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT));
label.setPadding(5, 5, 5, 5);
label.setBackgroundColor(Color.RED);
LinearLayout Ll = new LinearLayout(this);
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(LayoutParams.MATCH_PARENT,
LayoutParams.WRAP_CONTENT);
params.setMargins(5, 5, 5, 5);
//Ll.setPadding(10, 5, 5, 5);
Ll.addView(label,params);
tr.addView(Ll); // Adding textView to tablerow.
tr1=new TableRow(this);
/** Creating Qty Button **/
TextView uname = new TextView(this);
uname.setText("Username");
uname.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT));
uname.setPadding(5, 5, 5, 5);
uname.setBackgroundColor(Color.RED);
L2 = new LinearLayout(this);
params = new LinearLayout.LayoutParams(LayoutParams.MATCH_PARENT,
LayoutParams.WRAP_CONTENT);
params.setMargins(0, 5, 5, 5);
//Ll.setPadding(10, 5, 5, 5);
L2.addView(uname,params);
tr1.addView(L2); // Adding textview to tablerow.
// Add the TableRow to the TableLayout
tl.addView(tr);
tl.addView(tr1);
tr2=new TableRow(this);
/** Creating Qty Button **/
TextView email = new TextView(this);
email.setText("email");
email.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT));
email.setPadding(5, 5, 5, 5);
email.setBackgroundColor(Color.RED);
L3 = new LinearLayout(this);
params = new LinearLayout.LayoutParams(LayoutParams.MATCH_PARENT,
LayoutParams.WRAP_CONTENT);
params.setMargins(0, 5, 5, 5);
//Ll.setPadding(10, 5, 5, 5);
L3.addView(email,params);
tr2.addView(L3); // Adding textview to tablerow.
// Add the TableRow to the TableLayout
tl.addView(tr2);
}
Hope this will work for you.

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.

How to send entire data of specific row of table to server- Android

I am creating online shopping application for android and i have created a table which displays data from the server regarding the availability of the item. I have added a button next to it which adds that item of that row to the cart and it should send data to the server as well regarding which item was selected.
My problem is that i am not able to figure out how to send entire data of the specific row to the server and it should not re-direct from the current screen. Also my server is in php and is ready.
public class Availability extends Activity implements View.OnClickListener {

You should use AsyncTask for heavy-duty loadings such as http requests or parsing. Don't run such tasks on the ui thread, they will freeze it.
In the AsyncTask implementation's onPostExecute method you have the response you can deal with, populate your gui elements, update the views, etc.
A few references that may help you on how to proceed:
