話不多說直接上程式碼,希望能解決你們的問題,有不理解的可以給我留言

if (((ViewHolder_a) holder).editText.getTag() instanceof TextWatcher) {
    ((ViewHolder_a) holder).editText.removeTextChangedListener((TextWatcher) (((ViewHolder_a) holder).editText.getTag()));
}

    ((ViewHolder_a) holder).editText.setText(((Item_a) list.get(position)).getEditText());
 
TextWatcher watcher = 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) {
    }

    @Override
public void afterTextChanged(Editable editable) {
        if 
 
(TextUtils.isEmpty(editable.toString())) {
            ((Item_a)list.get(position)).setEditText("");
} else {
            ((Item_a) list.get(position)).setEditText(editable.toString());
}
    }
};
((ViewHolder_a) holder).editText.addTextChangedListener(watcher);
((ViewHolder_a) holder).editText.setTag(watcher);
