Horizontally scrolling in not working in android

Horizontally scrolling in not working in android - 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 :
(I didn't make any changes in xml file)

android.os.NetworkOnMainThreadException
is thrown when an application attempts to perform a network related operation on the main thread.
This is only thrown for applications targeting the Honeycomb SDK or higher versions. Ensure that your application is not attempting to perform any network
related operation on its main thread.

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.
