如何使用TimeSquare库创建CalendarPickerView

本文介绍如何使用TimeSquare库创建CalenderPickerView 。我们已经看到在许多应用程序中使用CalenderPickerView选择日期。借助该库，我们可以轻松地在我们的应用程序中添加日历。

方法：

1. 在build.gradle文件中添加支持库，并在“依赖项”部分中添加依赖项。该库提供内置的日历小部件和各种功能，例如选择特定的日期等。

   dependencies {
     implementation 'com.squareup:android-times-square:1.6.5@aar'
   }
   

2. 现在，将以下代码添加到activity_main.xml文件中。这将在应用程序中添加CalendarPickerView布局。

3. 现在，在MainActivity中添加以下代码。 Java文件。这将显示从当前日期算起的下一年的日历。将setOnDateSelectedListener添加到日历中，该日历在用户单击任何日期时被调用。该函数在屏幕上烘烤选定的日期。

       protected void onCreate(
           Bundle savedInstanceState)
       {
           super.onCreate(savedInstanceState);
           setContentView(R.layout.activity_main);
     
           // This will return us today date
           Date today = new Date();
     
           Calendar nextYear
               = Calendar.getInstance();
     
           // This will help us
           // to show date from
           // today to next year
           nextYear.add(Calendar.YEAR, 1);
     
           CalendarPickerView
               datePicker
               = findViewById(
                   R.id.calendar);
     
           // we have to initialize
           // our calender picker view
           // so we select min date as today
           // max date as next year
           // we call getTime() method
           // because we want to
           // retrieve date from it.
           datePicker
               .init(today, nextYear.getTime())
               .inMode(CalendarPickerView
                           .SelectionMode
                           .RANGE)
               .withSelectedDate(today);
     
           // when the user select
           // or un select any date then
           // this method called automatically.
           datePicker
               .setOnDateSelectedListener(
                   new CalendarPickerView
                       .OnDateSelectedListener() {
     
                           @Override
                           public void onDateSelected(Date date)
                           {
                               // we have to format our date
                               // object that's why we are
                               // using DateFormat class.
                               String selectedDate
                                   = DateFormat
                                         .getDateInstance(
                                             DateFormat.FULL)
                                         .format(date);
                               Toast
                                   .makeText(
                                       MainActivity.this,
                                       selectedDate,
                                       Toast.LENGTH_SHORT)
                                   .show();
                           }
     
                           @Override
                           public void onDateUnselected(
                               Date date)
                           {
                           }
                       });
       }
   }
