How to create a dynamic table with borders in android

I have Dynamic Table. When the user enter quantity then Value (TextView) should update (qty * price). My problem is that I am creating the TextView & EditText dynamically. How to get the Id of TextView?

 EditText txtQty = new EditText(this);
        txtQty.setId(i);
        txtQty.setVisibility(1);
        txtQty.setHint("0.00");
        txtQty.setInputType(InputType.TYPE_NUMBER_FLAG_DECIMAL);

        tr.addView(txtQty); 
        InputMethodManager mgr = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
        mgr.showSoftInput(txtQty, InputMethodManager.SHOW_IMPLICIT);

        ((InputMethodManager) getSystemService(Contex开发者_如何转开发t.INPUT_METHOD_SERVICE))  
        .hideSoftInputFromWindow(txtQty.getWindowToken(), 0);

        txtQty.addTextChangedListener(new TextWatcher() {
            public void afterTextChanged(Editable s) { 
                Log.v("TAG", "afterTextChanged" + s.toString());
            }

            public void beforeTextChanged(CharSequence arg0, int arg1, int arg2, int arg3) {
                Log.v("TAG", "beforeTextChanged");
            }

            public void onTextChanged(CharSequence s, int start, int before, int count) {
                Log.v("TAG", "onTextChanged");
            }
        });

        TextView txtVal = new TextView(this);
        txtVal.setTextSize(1, 12);
        createView(tr, txtVal,"0.00");

Inside the afterTextChanged() method I want to set the value(txtVal), for example txtVal .setText(215847.00);

How can we call txtVal inside the afterTextChanged() method?

Try declaring your txtVal before you addTextChangedListener(). You probalby need to declare txtVal as final TextView txtVal. Then you should be able to set the text of txtVal.
