无法将 Android CalendarView 更改为另一个月份（Samsung S Duos - Android 4.2.2）

Question

Android 在 API 11 中引入了 CalendarView。我已经在我的应用程序中实现了它，它似乎工作正常，因为它显示了一个看起来非常正常的整体 -月历，我可以 select 约会。它会触发适当的事件，我可以毫无问题地在我的代码中读取 selected 日期。

但是我不能提前出当月！文档说

A user can select a date by taping on it and can scroll and fling the calendar to a desired date.

（"taping" 出现在文档中；我认为这是 "tapping" 的拼写错误）

我试过轻扫、滑动、滚动，但没有任何反应。我需要做些什么才能启用此功能吗？

我的 XML 看起来像这样：

<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="match_parent"

    <!-- This linear layout is because the scrollview can have only 1 direct child -->
    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

编辑：
很抱歉 XML - 在我原来的帖子中我只有 CalendarView 但有人要求整个 XML.

还要排除它可能是我在我的三星 S5 (Android 5.0) 上测试过的设备所独有的可能性，并得到相同的结果。

Answer 1

根据我的假设，它不是滚动或滑动只是因为一个可滚动的父级，你可以在没有滚动视图的情况下检查它吗？

因为我用

测试过

<LinearLayout
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content">
    <CalendarView
    android:id="@+id/debulkcalendar"
    android:layout_width="match_parent"
    android:layout_height="240dp"
    android:minDate="01/01/2016"
    android:maxDate="11/30/2016"/>
</LinearLayout>

及其完美的工作

你可以使用 NestedScrollView

NestedScrollView is just like ScrollView, but it supports acting as both a nested scrolling parent and child on both new and old versions of Android. Nested scrolling is enabled by default.

Answer 2

@RBK 是对的，您的 parentView(ScrollView) 干扰了它的 childView(CalendarView)，这使得您的 CalendarView 不可滚动。但是，您可以创建自定义的 CalendarView 来扩展基础 CalendarView class 并覆盖 onInterceptTouchEvent 方法以获得您想要的。

创建您的自定义 CalendarView class:

public class CalendarViewScrollable extends CalendarView {

    public CalendarViewScrollable(Context context) {
        super(context);
    }

    public CalendarViewScrollable(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public CalendarViewScrollable(Context context, AttributeSet attrs,
                              int defStyle) {
        super(context, attrs, defStyle);
    }

    @Override
    public boolean onInterceptTouchEvent(MotionEvent ev) {
        if (ev.getActionMasked() == MotionEvent.ACTION_DOWN) {
            ViewParent p = getParent();
            if (p != null)
                p.requestDisallowInterceptTouchEvent(true);
        }
        return false;
    }
}

在您的 XML 布局文件中使用它：

<com.example.app.views.CalendarViewScrollable
 android:id="@+id/debulkcalendar"
 android:layout_width="match_parent"
 android:layout_height="240dp"
 android:minDate="01/01/2016"
 android:maxDate="11/30/2016" />
