How to change TextView's text on change of EditText's text?

I have an EditText box where the user can enter input. I need to display the input text in a TextView (which is placed below the EditText) while the user inputting the text.

Example:

If the user is entering any characters in EditText box, I need to display the same characters in TextView. In the same way, If the user deletes any character from EditText, I need to remove the same character from TextView. (Ultimately, I want to change TextView's text on change of EditText's text). I hope my requirement is clear now. How can I achieve this? Please guide me.

Add TextWatcher to your Edittext. in afterTextChanged() do your operation. http://developer.android.com/reference/android/text/TextWatcher.html

TextWatcher inputTextWatcher = new TextWatcher() {
    public void afterTextChanged(Editable s) { 
                textview.setText(s.toString());
    }
    public void beforeTextChanged(CharSequence s, int start, int count, int after){
    }
    public void onTextChanged(CharSequence s, int start, int before, int count) {
    }
};

editText.addTextChangedListener(inputTextWatcher);
