Question

I faced this problem
how can I retrieve string with another language (not English) from edittext?

Answer 1

You should be able to simply call toString() in your TextWatcher:

Set your listener:
name.addTextChangedListener(new GenericTextWatcher(name));

Define your listener:

private class GenericTextWatcher implements TextWatcher{
    private View view;
    private GenericTextWatcher(View view) {
        this.view = view;
    }

    public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) {}
    public void onTextChanged(CharSequence charSequence, int i, int i1, int i2) {}

    public void afterTextChanged(Editable editable) {
        String text = editable.toString();
    }
}

The language the String is in shouldn’t matter until you try to store or display it.
