Question

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(Context.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?

Answer 1

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.
