I bind these textviews and editview at runtime and now i want to do some validation for edittext inside listview ,but my EditView ID is same for all the Rows, so how can i apply validations in that editview plz help me .

Thanks in advance and Sorry for my poor English

My Code is Here

try {
        json = new JSONObject(status);
        getArray_Meter_Reading = new JSONArray();
        getArray_Meter_Reading = json.getJSONArray("meterReadings");

        myList = new ArrayList<HashMap<String, String>>();
        for (int i = 0; i < getArray_Meter_Reading.length(); i++) {

            map = new HashMap<String, String>();

            String meter_Name = getArray_Meter_Reading.getJSONObject(i)
                    .getString("MeterName").toString();

            String previous_Meter_Reading = getArray_Meter_Reading
                    .getJSONObject(i).getString("PrevMeterReading")
                    .toString();

            map.put("meterName", meter_Name);
            map.put("previousMeterReading", previous_Meter_Reading);

            myList.add(map);

        }

    } catch (JSONException e) {

        e.printStackTrace();
    }

    SimpleAdapter myAdapter = new SimpleAdapter(this, myList,
            R.layout.meter_reading_list, new String[] {
                    "meterName", "previousMeterReading" }, new int[] { R.id.txt_Meter_Name,
                    R.id.txt_Previous});

    lst.setAdapter(myAdapter);

    lst.setOnTouchListener(new View.OnTouchListener() {

        public boolean onTouch(View v, MotionEvent event) {
            if(event.getAction() == MotionEvent.ACTION_MOVE){
                lst.scrollBy(0, 1);
            }
            return false;
        }

Answer 1

You have two way for this.
1. Using Custom Adapter
2.As you are doing..but when you are selecting position then you need to get view id like 

lst.setOnTouchListener(new View.OnTouchListener() {

    public boolean onTouch(View v, MotionEvent event) {
        if(event.getAction() == MotionEvent.ACTION_MOVE){
            lst.scrollBy(0, 1);
        }
        return false;
    }
});

You should take operation on View v.This view will give you differnt id as it have.
I will suggest you to use custom adapter if not resolved this way as you are doing.
