Android Listview not refreshing

Hi my program should update the listview based on which radiobutton is selected and show all records of the one of the two tables.

As far as I can tell the records are in fact populated, it seems not to be refreshing the listview itself. Please help me solve this problem. Thanks in advance

Here is my code:

In onCreate:

RadioGroup rg = (RadioGroup) findViewById(R.id.radioGroup1);
        rg.setOnCheckedChangeListener(new OnCheckedChangeListener()
        {
            @Override
            public void onCheckedChanged(RadioGroup group, int checkedId)
            {
                RadioButton rb1 = (RadioButton) findViewById(R.id.radio0);
                RadioButton rb2 = (RadioButton) findViewById(R.id.radio1);

                switch(checkedId)
                {
                case R.id.radio0:
                    {
                        rb2.setChecked(false);          
//                      populateList();
//                      ListView lview = (ListView) findViewById(R.id.listView1);
//                      lview.invalidateViews();
                    }
                    break;
                case R.id.radio1:
                {
                        rb1.setChecked(false);
//                      populateList();
//                      ListView lview = (ListView) findViewById(R.id.listView1);
//                      lview.invalidateViews();
                }
                    break;
                }
                populateList();  
//              ListView lview = (ListView) findViewById(R.id.listView1);
//              lview.updateViewLayout();
            }


        });
