Enter double space to replace comma in multiautocompletetextview

Question

I want to add comma when I enter double space from keyboard in multiautocompletetextview. I search lots of thing in google. But can't reach my goal. I want to replace comma for double space entering by user.

So obviously, I must have to write something logic in ontextChange() or OnAfterTextChanged() in addtextwatcher listener.but i do't got event of after add 2 space.

I have already used comma tokenizer when select word from list.but i want to add comma when user entering double space using keypad.

Thanks in advance

The simplest solution i can provide you is to use String.replace(), Here is small code snippet to help you

 @Override
protected void onCreate(Bundle savedInstanceState) {

    ...

    edt.addTextChangedListener(textWatcher);
}

And TextWatcher which you are going to set on EditText

TextWatcher textWatcher = new TextWatcher() {
    @Override
    public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) {

    }

    @Override
    public void onTextChanged(CharSequence charSequence, int i, int i1, int i2) {
        edt.removeTextChangedListener(textWatcher);
        String text = edt.getText().toString();
        text = text.replace("  ", ",");
        edt.setText(text);
        edt.setSelection(text.length());
        edt.addTextChangedListener(textWatcher);
    }

    @Override
    public void afterTextChanged(Editable editable) {

    }
};
