TimePickerDialog构造函数问题

Question

if (v == btnEndTimePicker) {

            final Calendar c = Calendar.getInstance() ;
            mHour = c.get(Calendar.HOUR_OF_DAY);
            mMinutes = c.get(Calendar.MINUTE);
            TimePickerDialog timePickerDialog = new TimePickerDialog(true, this,
                    (view, hour, minutes) -> {
                        return editStartTime.setText((hour + ":" + minutes), mHour, mMinutes);
                    });
            timePickerDialog.show();
        }
        if (v == btnStartTimePicker) {

            final Calendar c = Calendar.getInstance() ;
            sHour = c.get(Calendar.HOUR_OF_DAY);
            sMinutes = c.get(Calendar.MINUTE);
            CalendarDialog timePickerDialog = new CalendarDialog(true, this,
                    (view, hour, minutes) -> {
                        return editStartTime.setText((hour + ":" + minutes), sHour, sMinutes);
                    });
            timePickerDialog.show();
        }

我不知道在这里要做什么，我使用了类似的代码来弹出一个Calendar Date对话框，并选择一个日期，然后将其放入EditText字段中。当我为TimePickerDialog这样做的时候，它会告诉我它应该是一个char[]，而不是一个字符串。

您给TimePickerDialog对象的get提供了错误的参数

     public TimePickerDialog (Context context,  
            TimePickerDialog.OnTimeSetListener listener, 
            int hourOfDay, 
            int minute, 
            boolean is24HourView)

替换这个

  TimePickerDialog timePickerDialog = new TimePickerDialog(true, this,
                (view, hour, minutes) -> {
                    return editStartTime.setText((hour + ":" + minutes), mHour, mMinutes);
                });

使用

TimePickerDialog timePickerDialog = new TimePickerDialog(this,listener,2,25,true);

这些都是正确的参数，请查看
