Question

我想使用此库https://github.com/wdullaer/MaterialDateTimePicker来显示日期选择器对话框

implementation "com.wdullaer:materialdatetimepicker:3.6.4"

这是我的代码在我的片段中

import com.wdullaer.materialdatetimepicker.date.DatePickerDialog

        val now = Calendar.getInstance()
        val currentYear: Int = now.get(Calendar.YEAR)
        val currentMonth: Int = now.get(Calendar.MONTH)
        val currentDay: Int = now.get(Calendar.DAY_OF_MONTH)

        val datePickerDialog = DatePickerDialog.newInstance(DatePickerDialog.OnDateSetListener { view, year, monthOfYear, dayOfMonth ->

            // do something here


        }, currentYear, currentMonth, currentDay)

        datePickerDialog.setTitle("INI JUDUL")
        datePickerDialog.setAccentColor(resources.getColor(R.color.colorPrimary))
        datePickerDialog.setOkText("SIP")
        datePickerDialog.setCancelText("GA JADI")
        datePickerDialog.show(fragmentManager,"")

但是当我想在此行datePickerDialog.show(fragmentManager,"")中显示日期选择器对话框时出现错误，

我相信我提供了正确的论点，但是....它仍然给出错误

这是片段管理器类型：

但是如果我强制这样展开，它仍然会出错

对于androidX，您应该使用最新版本：

implementation 'com.wdullaer:materialdatetimepicker:4.2.3'

然后是片段：

fragmentManager?.let { manager ->
            datePickerDialog.show(manager, "DatePickerDialog")
        }

我不知道它是不是完美的方法，我是否尝试过这段代码并且它可以工作，但是方法已被弃用。如果您找到其他方法，请告诉我。

val now = Calendar.getInstance()
        val currentYear: Int = now.get(Calendar.YEAR)
        val currentMonth: Int = now.get(Calendar.MONTH)
        val currentDay: Int = now.get(Calendar.DAY_OF_MONTH)

        val datePickerDialog = DatePickerDialog.newInstance(DatePickerDialog.OnDateSetListener { view, year, monthOfYear, dayOfMonth ->

            // do something here


        }, currentYear, currentMonth, currentDay)

        datePickerDialog.setTitle("INI JUDUL")
        datePickerDialog.setAccentColor(resources.getColor(R.color.colorPrimary))
        datePickerDialog.setOkText("SIP")
        datePickerDialog.setCancelText("GA JADI")
        datePickerDialog.show(activity!!.fragmentManager, "Datepickerdialog");

希望它能工作！

只需尝试一下，它就可以完美运行：

    val now = Calendar.getInstance()
    val currentYear: Int = now.get(Calendar.YEAR)
    val currentMonth: Int = now.get(Calendar.MONTH)
    val currentDay: Int = now.get(Calendar.DAY_OF_MONTH)

    val datePickerDialog = DatePickerDialog.newInstance(DatePickerDialog.OnDateSetListener { view, year, monthOfYear, dayOfMonth ->

        // do something here


    }, currentYear, currentMonth, currentDay)

    datePickerDialog.setTitle("INI JUDUL")
    datePickerDialog.setAccentColor(resources.getColor(R.color.colorPrimary))
    datePickerDialog.setOkText("SIP")
    datePickerDialog.setCancelText("GA JADI")
    datePickerDialog.show(parentFragmentManager,"")

尝试清理项目并使缓存无效。这可能会有所帮助。
