滚动时如何在NumberPicker中显示更多数字

Question

滚动时如何在数字选择器中显示更多项目/数字，因为它仅显示3个数字。这是我的代码

void OnTapGestureRecognizerTapped(object sender, EventArgs args)
 {
    isListVisible = !isListVisible;
    listSection.IsVisible = !isListVisible;
 }

我更改了您的代码，请尝试此操作，这会有所帮助

NumberPicker starttime = findViewById(R.id.timeListview);
String[] time = {"12:00 AM", "12:30 AM", "01:00 AM", "01:30 AM", "02:00 AM", "02:30 AM", "03:00 AM","11:00 PM", "11:30 PM"};
    starttime.setMinValue(0);
    starttime.setMaxValue(time.length-1);
    starttime.setDisplayedValues(time);
    starttime.setWrapSelectorWheel(true);
