如何禁用 CalendarView 的滚动 - Android Dev

Question

I am currently refreshing my android developement skills and came across the CalendarView component. I wanted to disable the scrolling of the calendar and instead enable the arrows to browse through the calendar.

What I want to know is the following: How can I disable the scrolling from the CalendarView? And why does Android Studio show me the arrow browse-version in the Designer-Mode but compiles and runs the scroll-version of the calendar?

I am running an Android VM, a "Galaxy Nexus" with API 22. I also posted the "build.gradle" further below.

What Android shows me/What I want:

What Android Studio compiles & runs:

Answer 1

Use MaterialComponents Theme, it will most probably solve the issue.

In your values/themes file replace the parent them with this,

parent="Theme.MaterialComponents.DayNight.DarkActionBar"

If you don't want Action Bar then,

parent="Theme.MaterialComponents.DayNight.NoActionBar"

And if you only want to show Light Coloured Calendar view regardless of Devices's theme use,

parent="Theme.MaterialComponents.Light.NoActionBar"

Thanks to Vaibhav Goyal i came across the solution.

The API level I used was to low (API 22, Android 5.1). Changing that to API 23 (Android 6.0) solved my problem. Now it shows me the CalendarView with arrow-navigation instead of the scroll version!

yourCalenenderId.addOnItemTouchListener(object : RecyclerView.SimpleOnItemTouchListener() {
        override fun onInterceptTouchEvent(rv: RecyclerView, e: MotionEvent): Boolean {
            return if (e.action == MotionEvent.ACTION_MOVE) {
                true
            } else {
                super.onInterceptTouchEvent(rv, e)
            }
        }
    })
