Android CalendarView not displaying the days

Question

I have been using Android CalendarView to get a Calendar displayed on my screen in a Appointment Manager Application. In my case so far, the app user will be able to create an appointment by selecting the Create an appointment button and I intend to display a Calendar to select a date along with three or four text inputs. But I tend to always get only the CalendarView month, year and the headings of the week's days but not the list of days of the month. I am confused whether it is an issue related to the layout I am using or whether it is some other reason. The following are the source code of the related class and layout file.

CreateAppointmentActivity.java

package lk.iit.appointmentmanagerapp.activities;

import android.app.Activity;
import android.os.Bundle;
import android.widget.CalendarView;
import android.widget.Toast;
import android.widget.CalendarView.OnDateChangeListener;

public class CreateAppointmentActivity extends Activity {

    CalendarView calendar;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_create_appointment);
        this.initializeCalendar();  
    }

    public void initializeCalendar() {
        calendar = (CalendarView) findViewById(R.id.calendar);

        calendar.setShowWeekNumber(false);

        calendar.setFirstDayOfWeek(2);

        calendar.setOnDateChangeListener(new OnDateChangeListener() {
            @Override
            public void onSelectedDayChange(CalendarView view, int year, int month, int day) {
                Toast.makeText(getApplicationContext(), day + "/" + month + "/" + year, Toast.LENGTH_LONG).show();
            }
        });
    }

}

I am relatively new to Android development and its user interface designing. Can anybody please suggest me any solutions for the above case?

Answer 1

change the layout parameters to match_parent

<CalendarView
  android:id="@+id/calendar"
  android:layout_width="match_parent" 
  android:layout_height="match_parent"
  android:layout_centerHorizontal="true"
  android:layout_below="@+id/create_activity_title"
    />

Answer 2

I fix it on an old Samsung on Kitkat with minHeight

<CalendarView
                android:id="@+id/fromCalendarView"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:layout_centerHorizontal="true"
                android:layout_weight="50"
                android:minHeight="300dp"/>

Answer 3

Set minHeight dont work. Bellow works

            <CalendarView

                android:layout_width="match_parent"
                android:layout_height="300dp"
                android:layout_below="@+id/toolbar" />

Answer 4

Above Answer worked for me.

<CalendarView
android:id="@+id/calendarView"
android:layout_width="match_parent"
android:layout_height="300dp"
android:layout_below="@+id/toolbar" />
