In My Application there is two EditText and one TextView.
I have set the Two Textwatcher on that both EditText. Based on the Value in that EditText, The Value of another EditText is changed and it also apply to textView.
All Goes Nice. But if i put the that Another Edittext as like the value of it to be change based on the Another EditText then it gives me stackOverflow Error.
I dont know Where i am wrong. And I am not able to Put the TextWatcher for both the EditText to change the value with respect to each other.

Please Help me for it.
Thanks.
Code :

 amountText.setText(""); // TextView
    excludedText.setText(""); // EditText
    includedText.setText(""); // EditText


    includedText.addTextChangedListener(new TextWatcher() {

        @Override
        public void onTextChanged(CharSequence s, int start, int before, int count) {

                if(!(includedText.getText().toString().equals("")))
                {
                    double included = Double.parseDouble(includedText.getText().toString());
                    included = roundTwoDecimals(included);
        //          double amountValue = (excluded*15/100);

                    String amt = String.valueOf(roundTwoDecimals(included-(included/1.15)));
                    String excluded = String.valueOf(included/1.15);
                    System.out.println("The Amount is: "+amt);
                    amountText.setText(amt);
                    try{
                        excludedText.setText("");
                        excludedText.setText(excluded); //////// Error Line
                    }

This is a problem of stackoverflow you are going to infinite loop.

You are updating value of one edittext from second one and vice-verse .

For example ::

When you enter character in first edit text it will set text of second edit text and at that time in second edit text you have write a code to set text of first edit text so that you are going to infinite loop.

EDIT

et1 = (EditText)findViewById(R.id.et1);
et2 = (EditText)findViewById(R.id.et2);

OnKeyListener onKeyListener = new OnKeyListener() {

            @Override
            public boolean onKey(View v, int keyCode, KeyEvent event) {
                String str = ((EditText)v).getText().toString();
                if(v == et1) {
                    et2.setText(str);
                }else {
                    et1.setText(str);
                }
                return false;
            }
        };
        et1.setOnKeyListener(onKeyListener);
        et2.setOnKeyListener(onKeyListener);
