calendarViewShown在Android 5.0 Lollipop上不被兑现 [英] calendarViewShown is not being honored on Android 5.0 Lollipop

问题描述

我正在通过The Big Nerd Ranch的Android指南工作。在
分配刑事意图中，我使用DatePicker与以下
布局。

在5.0之前的设备上，日历不会按照定义的DatePicker显示在
的布局，但Android 5.0忽略这个并显示一个日历。任何想法
这可能会发生什么？

解决方案

该解决方案已发布此处

您有要使用 android：calendarViewShown =false和 android：datePickerMode =spinner。

这解决了这个问题。

 < DatePicker xmlns：android =http：// $（$）
 android：id =@ + id / dialog_date_datePicker
 android：layout_width =match_parent
 android：layout_height =match_parent
 android：calendarViewShown =false
 android：datePickerMode =spinner> 
< / DatePicker> 
  

I am working through The Big Nerd Ranch's Android Guide. In the assignment Criminal Intent I am using DatePicker with following layout.

On pre-5.0 devices, calendar is not shown in DatePicker as defined in the layout but Android 5.0 ignores this and shows a calendar. Any idea what might be going on here?

Full code is available on Github.

dialog_date.xml

<?xml version="1.0" encoding="utf-8"?>
<DatePicker xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/dialog_date_datePicker"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:calendarViewShown="false" >
</DatePicker>

    public static DatePickerFragment newInstance(Date date) {

        args.putSerializable(EXTRA_DATE, date);
        DatePickerFragment fragment = new DatePickerFragment();
        fragment.setArguments(args);
        return fragment;

    private void sendResult(int resultCode) {

        Intent i = new Intent();
        i.putExtra(EXTRA_DATE, mDate);
        getTargetFragment().onActivityResult(getTargetRequestCode(),

    @Override

                // calendar

                mDate = new GregorianCalendar(year, month, day, hour, minute)
                        .getTime();

                getArguments().putSerializable(EXTRA_DATE, mDate);
            }
        });

        return new AlertDialog.Builder(getActivity())
                .setView(v)
                .setTitle(R.string.date_picker_title)
                .setPositiveButton(android.R.string.ok,
                        new DialogInterface.OnClickListener() {
                            public void onClick(DialogInterface dialog,
                                    int which) {
                                sendResult(Activity.RESULT_OK);
                            }
                        }).create();

    }
}

解决方案

The solution has been posted here

You have to use both android:calendarViewShown="false" and android:datePickerMode="spinner".

This solves it.

<DatePicker xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/dialog_date_datePicker"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:calendarViewShown="false"
    android:datePickerMode="spinner" >
</DatePicker>
