Populating Table Layout using JSON String

Question

I have a JSON String returned by my web service as follows:

{"checkrecord"[{"rollno":"abc2","percentage":40,"attended":12,"missed":34}],"Table1":[]}

The above String represents my dataset. I have converted the String to a JSON Object and I now want to put the data in the String into a TableLayout.

I want the table to be like this when displayed on android app:

    rollno       percentage    attended    missed
     abc2          40              12        34

This is the code I am using as of now :

    //json processing code

 public void jsonprocessing(String c)
   {
       try 
       {

       JSONObject jsonobject = new JSONObject(c);

       JSONArray array = jsonobject.getJSONArray("checkrecord");

        int max = array.length();

       for (int j = 0; j < max; j++)
       {

    JSONObject obj = array.getJSONObject(j);
    JSONArray names = obj.names();

    for (int k = 0; k < names.length(); k++) 
        {
             name = names.getString(k);
            value= obj.getString(name);
               createtableLayout();  

        }


       }     

     } 

  catch (JSONException e)           
   {                
      // TODO Auto-generated catch block
    e.printStackTrace();        
}

 }

//create table layout
public void createtableLayout()
{

     Log.d("values",value); //I am able to see the values abc2,40,12 and 34 over  here in logcat  
     TableLayout t= (TableLayout)findViewById(R.id.tablelayout);
         TableRow r1=new TableRow(this);
         r1.setLayoutParams(new LayoutParams(
         LayoutParams.FILL_PARENT,
         LayoutParams.WRAP_CONTENT));    
         TextView t1 = new TextView(this);
         t1.setText(value);
         t1.setTextColor(Color.BLACK);
         t1.setLayoutParams(new LayoutParams(
             LayoutParams.FILL_PARENT,
             LayoutParams.WRAP_CONTENT));
         r1.addView(t1);
         t.addView(r1, new TableLayout.LayoutParams( LayoutParams.FILL_PARENT,LayoutParams.WRAP_CONTENT));

 }

My TableLayout contains a button and a EditText as the first TableRow. After I click the button I get the JSON String. So I need to insert 2 TableRows dynamically after that as per my requirement.

My xml as of now is as follows:

   <?xml version="1.0" encoding="utf-8"?>
   <TableLayout 
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/tablelayout"
        android:layout_height="fill_parent" 
        android:layout_width="fill_parent"
        android:background="#000044">
   <TableRow> 

   <EditText 
        android:id="@+id/edittext" 
        android:width="200px" />

   <Button 
        android:id="@+id/button" 
        android:text="Check Record"/>

   </TableRow> 

   </TableLayout>

So my problem is how to add those 2 extra TableRows so as to populate them with the String values ?

My code isn't working fine. I am not able to get the required output.

Can anyone help me in this?

Thanks

Answer 1

you can use multicolumn listview for your purpose,

Parse the JSON response and get values into different strings and use this blog for your purpose

Multicolumn Listview

Answer 2

You, probably, can define those 2 more rows in your XML and make them initially invisible. Then upon receiving your data put your data in those rows and make them visible.
