How to remove all listeners added with addTextChangedListener

Question

I have a ListView where each row has an EditText control. I want to add a TextChangedListener to each row; one that contains extra dat

Answer 1

I resolved this situation without extend TextView class.

private ArrayList mEditTextWatcherList = new ArrayList<>();
private TextWatcher mTextWatcher1;
private TextWathcer mTextWatcher2;

mTextWathcer1 = new TextWatcher() {
    @Override
    public void beforeTextChanged(CharSequence s, int start, int count, int after) {}

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

    @Override
    public void afterTextChanged(Editable s) {}
};

mTextWathcer2 = new TextWatcher() {
    @Override
    public void beforeTextChanged(CharSequence s, int start, int count, int after) {}

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

    @Override
    public void afterTextChanged(Editable s) {}
};

@Override 
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity);

    setListener(mTextWatcher1);
    setListener(mTextWatcher2);

    removeListeners();
}

private setListener(TextWatcher listener) {
    mEditText.addTextChangedListener(listener);
    mEditTextWatcherList.add(listener);
}

private removeListeners() {
    for (TextWatcher t : mEditTextWatcherList)
        mEditText.removeTextChangedListener(t);

    mEditTextWatcherList.clear();
}
