Is Textwatcher is used only for Edittext android

Question

I want to use TextWatcher(textChangelistener) for a TextView in android I made a study on that there I came to know that, it is possible to have OnTextChangeListener for EditText only. But my TextView will automatically change according to the changes in the someother EditTexts. so I want to have a OnTextChangedListener to proceed with further calculations..

can anyone help me doing this!!!!! Thanks in Advance

yes you can use textwatcher for your textview as well in the same way they has been used for edittext — Anjali, Sep 15 '16 at 09:15
What exactly are you asking? I think your question is unclear, you should edit and rephrase it. — Diti, Sep 15 '16 at 09:16

As far as I understood your question EditText's text is changed by user dynamically so we need TextWatcher for EditText, but in case of TextView whatever text is being changed will be changed by developer only. So you should perform operations on it whenever you are setting text to TextView. Still if you want to use that use it as follows.

textView.addTextChangedListener(new TextWatcher() {

    boolean editing=false;

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

    }

    @Override
    public void beforeTextChanged(CharSequence s, int start, int count,int after) {

    }

    @Override
    public void afterTextChanged(Editable s) {
        if (!editing){
           editing=true;
           s.append("A");
           editing=false;
    }


    }
});
