In this blog about Android Calendar View Example, learn how to implement the Cosmo Android Calendar Library in Android project and build a calendar app. Android Calendar View Example Android Cosmo calendar library is an advance Android Calendar Library that you can easily implement in your android studio project and with a bit of customisation can select single, multiple or a range of dates. Here is a step by step guide to work with Android Cosmo Calendar library. Android Calendar View Example Getting Started Create a blank new Android Studio project and add following new line of dependency to your build.gradle (app) file. dependencies { implementation 'com.github.applikeysolutions:cosmocalendar:1.0.4' } Building the layout Because its a build from scratch project, we are using a simple LinearLayout with vertical orientation. To this add, CalendarView (from Cosmo calendar library) and a button. Here is the layout we are building: Here is the code for the same: <Button android:textColor"#FFF" android:backgroundTint"@color/colorAccent" android:id"@+id/selectButton" android:layout_width"wrap_content" android:layout_height"wrap_content" android:textSize"15sp" android:padding"10dp" android:textAlignment"center" android:layout_gravity"center" android:layout_margin"10dp" android:text"Search"/> Let's Code It Now in the MainActivity.java file (in whichever activity you have inflate the view), use findViewById to attach widgets. CalendarView calendarView;Button button;String startDate, endDate; Now in the calendarView of Cosmo Calendar Library, to set first day of the week, we use following line of code: //Set First day of the weekcalendarView.setFirstDayOfWeek(Calendar.MONDAY); To set the calendar orientation use: //Set Orientation 0 Horizontal | 1 VerticalcalendarView.setCalendarOrientation(0); To set weekend days we use: calendarView.setWeekendDays(new HashSet(){{ add(Calendar.SATURDAY); add(Calendar.SUNDAY);}}); The Cosmo Calendar Library comes in 4 different selection type: SingleMultipleRange Customized To set your calendarView selection type, use the following line of code: calendarView.setSelectionType(SelectionType.RANGE); On Button selection here is how you generate result for them: button.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { if (calendarView.getSelectionManager() instanceof RangeSelectionManager) { RangeSelectionManager rangeSelectionManager (RangeSelectionManager) calendarView.getSelectionManager(); if(rangeSelectionManager.getDays() ! null) { startDate rangeSelectionManager.getDays().first.toString(); endDate rangeSelectionManager.getDays().second.toString(); } else { Toast.makeText(MainActivity.this, "Invalid Selection", Toast.LENGTH_SHORT).show(); } } }}); If you are planning to show a Calendar Dialog there is a code for that too: new CalendarDialog(this, new OnDaysSelectionListener() { @Override public void onDaysSelected(List selectedDays) { } }).show(); Here is the complete source code for the Android Calendar View Example: package com.example.androidcalendarview; import androidx.appcompat.app.AppCompatActivity; import android.os.Bundle; import android.view.View; import android.widget.Button; import android.widget.Toast; import com.applikeysolutions.cosmocalendar.dialog.CalendarDialog; import com.applikeysolutions.cosmocalendar.dialog.OnDaysSelectionListener; import com.applikeysolutions.cosmocalendar.model.Day; import com.applikeysolutions.cosmocalendar.selection.MultipleSelectionManager; import com.applikeysolutions.cosmocalendar.selection.RangeSelectionManager; import com.applikeysolutions.cosmocalendar.selection.SingleSelectionManager; import com.applikeysolutions.cosmocalendar.settings.appearance.ConnectedDayIconPosition; import com.applikeysolutions.cosmocalendar.utils.SelectionType; import com.applikeysolutions.cosmocalendar.view.CalendarView; import java.util.Calendar; import java.util.HashSet; import java.util.List; public class MainActivity extends AppCompatActivity { CalendarView calendarView; Button button; String startDate, endDate; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); calendarView findViewById(R.id.cosmo_calendar); button findViewById(R.id.selectButton); //Set First day of the week calendarView.setFirstDayOfWeek(Calendar.MONDAY); //Set Orientation 0 Horizontal | 1 Vertical calendarView.setCalendarOrientation(0); calendarView.setWeekendDays(new HashSet(){{ add(Calendar.SATURDAY); add(Calendar.SUNDAY); }}); //Range Selection calendarView.setSelectionType(SelectionType.RANGE); button.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { if (calendarView.getSelectionManager() instanceof RangeSelectionManager) { RangeSelectionManager rangeSelectionManager (RangeSelectionManager) calendarView.getSelectionManager(); if(rangeSelectionManager.getDays() ! null) { startDate rangeSelectionManager.getDays().first.toString(); endDate rangeSelectionManager.getDays().second.toString(); } else { Toast.makeText(MainActivity.this, "Invalid Selection", Toast.LENGTH_SHORT).show(); } } } }); } } Interested in creating your own custom caledar, see here.
