以编程方式更改 inputType 后，EditText 允许任何操作

Question

我有一个只接受数字的 editText。我有 4 种类型：日期、年份、数学、琐事。我使用复选框在这些类型之间切换。

InputType 变化如下：

日期：null（用户将点击编辑文本来选择日期）年份，
数学，琐事：signed_number

默认情况下，输入类型设置为知识问答，我只能输入数字，但当我至少在我的类型之间切换一次时，我可以输入任何内容。它仅适用于 Date 类型。

处理这一切的监听器：

rgType.setOnCheckedChangeListener { _, checkedId ->
        val checked = findViewById<RadioButton>(checkedId)
        numType = when (checked.text) {
            "Year" -> NumType.YEAR
            "Date" -> NumType.DATE
            "Math" -> NumType.MATH
            else -> NumType.TRIVIA
        }

        tNumber.setText("")
        tAnswer.text = ""
        when (numType) {
            NumType.DATE -> {
                tNumber.hint = "CHOOSE A DATE"
                tNumber.inputType = InputType.TYPE_NULL
                tNumber.hideKeyboard()
            }
            NumType.YEAR -> {
                tNumber.hint = "TYPE A YEAR"
                tNumber.inputType = InputType.TYPE_NUMBER_FLAG_SIGNED
                tNumber.hideKeyboard()
            }
            else -> {
                tNumber.hint = "TYPE A NUMBER"
                tNumber.inputType = InputType.TYPE_NUMBER_FLAG_SIGNED
                tNumber.hideKeyboard()
            }
        }
        Log.d("Input", tNumber.inputType.toString())
    }

**更新代码：**

rgType.setOnCheckedChangeListener { _, checkedId ->
        val checked = findViewById<RadioButton>(checkedId)
        numType = when (checked.text) {
            "Year" -> NumType.YEAR
            "Date" -> NumType.DATE
            "Math" -> NumType.MATH
            else -> NumType.TRIVIA
        }

        tNumber.setText("")
        tAnswer.text = ""
        when (numType) {
            NumType.DATE -> {
                tNumber.hint = "CHOOSE A DATE"
                tNumber.inputType = InputType.TYPE_NULL
                tNumber.hideKeyboard()
            }
            NumType.YEAR -> {
                tNumber.hint = "TYPE A YEAR"
                tNumber.inputType = InputType.TYPE_CLASS_NUMBER or InputType.TYPE_NUMBER_FLAG_SIGNED
                tNumber.hideKeyboard()
            }
            else -> {
                tNumber.hint = "TYPE A NUMBER"
                tNumber.inputType = InputType.TYPE_CLASS_NUMBER or InputType.TYPE_NUMBER_FLAG_SIGNED
                tNumber.hideKeyboard()
            }
        }
        Log.d("Input", tNumber.inputType.toString())
    }

只有4种输入类型：

InputType.TYPE_CLASS_DATETIME
InputType.TYPE_CLASS_NUMBER
InputType.TYPE_CLASS_PHONE
InputType.TYPE_CLASS_TEXT

其他都是flag。如果要设置标志，则必须使用 or 运算符。示例：

tNumber.inputType = InputType.TYPE_CLASS_DATETIME or InputType.TYPE_DATETIME_VARIATION_DATE

tNumber.inputType = InputType.TYPE_CLASS_TEXT or InputType.TYPE_TEXT_FLAG_CAP_CHARACTERS or InputType.TYPE_TEXT_FLAG_MULTI_LINE
