Need to access the text of a TextView child of a ListView

I have a ListView that contains a list of TextViews, and in my onItemClick() method, I need to get at the string value of the TextView that was clicked. How do I do this?

Here is my onItemClick function:

public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
                    long arg3) {
                Intent startNewActivity=new Intent(getBaseContext(),DetailCurrencyActivity.class);
                startActivity(startNewActivity);



            }

Update 1: This is the custom list adapter where the listview gets populated:

//custom list adapter
    public class listRecordAdapter extends BaseAdapter{
        private JSONObject[] listOf_Records=null;
        private Context context;
        private TextView ticker,value,value2,changeval;

        public listRecordAdapter(Context context,JSONObject[] listOf_Records){
            Log.i("Concerts", "artistEventAdapter: constructor");
            this.listOf_Records=listOf_Records;
            this.context=context;
        }

        @Override
        public int getCount() {         
            return listOf_Records.length;
        }

        @Override
        public Object getItem(int position) {           
            return listOf_Records[position];
        }

        @Override
        public long getItemId(int position) {           
            return position;
        }

        @Override
        public View getView(int position, View convertView, ViewGroup parent) {
            Log.i("CurrencyActivity", "artistListAdapter: getView");
            if(convertView==null){
                convertView=LayoutInflater.from(context).inflate(R.layout.forex_listview_item, null);
            }
            try{

                ticker=(TextView)convertView.findViewById(R.id.ticker);
                ticker.setText(this.listOf_Records[position].开发者_如何学PythongetString("ticker"));
                Log.i("CurrentActivity", "listRecordAdapter: getView ticker->"+ticker.getText());

                value=(TextView)convertView.findViewById(R.id.value);           
                value.setText(this.listOf_Records[position].getString("value"));
                Log.i("CurrentActivity", "listRecordAdapter: getView value->"+value.getText());

                value2=(TextView)convertView.findViewById(R.id.value2);         
                value2.setText(this.listOf_Records[position].getString("value2"));
                Log.i("CurrentActivity", "listRecordAdapter: getView value2->"+value2.getText());

                changeval=(TextView)convertView.findViewById(R.id.changeval);           
                changeval.setText(this.listOf_Records[position].getString("changeval"));
                Log.i("CurrentActivity", "listRecordAdapter: getView changeval->"+changeval.getText());
            }catch(Exception ex){
                Log.i("CurrencyActivity", "listRecordAdapter: getView exiting with exception message->"+ex.getMessage());
            }
            return convertView;
        }

    }

The getView method gives you a number of ways of a accessing the data. Presumably you used some sort of array adapter to give you data to the ListView in the first place. The first int, position, gives you the index into your original list. See the [getView docs][1] for details. That is probably the easiest way to get the information.

Otherwise, you could try to find the item with the View you are provided.

[1]: http://developer.android.com/reference/android/widget/AdapterView.OnItemClickListener.html#onItemClick(android.widget.AdapterView, android.view.View, int, long)

TextView tv = (TextView) arg1;
String myString = tv.getText().toString();

arg1 ( as you have it there at least) is a reference to the root View of the row that was clicked.
