Answer 1

It seems very simple but accidentally i have tested this, and it works well. I hope this will also help you...

First create separate xml file which contains only CalendarView. Named “cal_view.xml”

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

    <android.widget.CalendarView
        android:layout_width="200dp"
        android:layout_height="200dp" />

</LinearLayout> 

Then include this xml file in to your main xml file, just like following. Instead of your CalanderView, include the xml file.

 <include
     android:id="@+id/subCategory"
     layout="@layout/cal_view" />

As you mention your problem,

Issues

Your resource xml file (layout) not in optimal way. As android guideline don't use static height and weight for ViewGroup. Please read http://developer.android.com/training/improving-layouts/optimizing-layout.html

Solution :

In My opinion, you should create your own class for creating Calendar view.In which you apply all the properties and attribute.

I am show a demo application for the Calender view.http://www.androidviews.net/2013/01/ics-calendarview/ In these application having a better way to use the calendar view. also I am mention some Git URL for the other an custom Calendar view

• https://github.com/dwivedi/android-times-square
• https://github.com/dwivedi/ExtendedCalendarView
• https://github.com/SimonVT/android-calendarview

In above Application, showing the right way to use CalendarView

Here I am showing screenshot for the Calenderview application

If any problem, Please Let me know, I will create sample demo for the same.
