Android : How to get the values of the selected items from textviews in android?

I need to retrive values from selected items from a listview. I already got the values passed to the layout correctly throughout this listview but always it gets the values at the very first row. Simply I cannot select and pass the value from what I need! Please help me with this. I'm new to android.

  public void reuseUnit() {


            TextView t1 = (TextView) findViewById(R.id.lblLUnitName);
            TextView tg = (TextView) findViewById(R.id.txtG);
            TextView t2 = (TextView) findViewById(R.id.lblLNoofBulbs);
            TextView t3 = (TextView) findViewById(R.id.lblLNoOfFans);
            String name=t1.getText().toString();
            Intent RuseName = new Intent(CreateNewUnit.this,
                    HomePage.class);
            ;
            int gG= Integer.valueOf(tg.getText().toString());
            int Rbulb= Integer.valueOf(t2.getText().toString());
            int RFans= Integer.valueOf(t3.getText().toString());

            RuseName.putExtra("keyRName",name);
            RuseName.putExtra("keyG",gG);
            RuseName.putExtra("keyRbulbs",Rbulb);
            RuseName.putExtra("keyRFans",RFans);
                startActivity(RuseName);
