Question

我使用了在这里找到的代码：Suggestion text

1）问题是当值和列表中的现有单词（word_list）完全匹配时，我看不到文本输入。

2）而且，当我开始输入与一个现有单词相似的内容，然后输入不在该现有单词中的字母时，看不到文本输入。

示例： 1）我手动写了“棕色”，我看不到输入 2）我手动写了“兄弟”，我看不到输入。如果我输入“ brod”和其他任何字母，我都会看到文本输入。

我的代码：

class FirstNameTextInput(TextInput):

    cur2 = con.cursor()
    sql_first_name = cur2.execute('SELECT firstName from `employee`')
    first_name_employee = [str(t[0]) for t in sql_first_name]

    word_list = ('The quick brown fox jumps over the lazy old dog').split(' ')

    def on_text(self, instance, value):
        self.suggestion_text = ''
        first_name_employee = list(set(
        self.first_name_employee + value[:value.rfind(' ')].split(' ')))

        val = value[value.rfind(' ') + 1:]
        if not val:
            return
        try:
            # grossly inefficient just for demo purposes
            word = [word for word in first_name_employee
                if word.startswith(val)][0][len(val):]
            if not word:
                return
            self.suggestion_text = word
        except IndexError:
            print('Index Error.')

    def keyboard_on_key_down(self, window, keycode, text, modifiers):
        if self.suggestion_text and keycode[1] == 'enter':
            self.insert_text(self.suggestion_text + ' ')
            return True

        return super(FirstNameTextInput, self).keyboard_on_key_down(window, keycode, text, modifiers)
