本文介绍了在 onCalendarPageChangeListener Android 中获取日历的月份的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我正在创建一个使用 applandeo 的 material-calendar-view 库的小型应用程序.
I'm creating a small application that uses the material-calendar-view library from applandeo.
每当用户单击前进或上一个按钮时，我都会尝试获取当前月份和年份.
I'm trying to get the current month and year whenever the user clicks the forward or previous buttons.
public class CalendarActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_calendar);
CalendarView calendarView = findViewById(R.id.calendarView);
//Move to another Activity
calendarView.setOnDayClickListener(eventDay -> {
// code to move to another activity
//...
});
calendarView.setOnForwardPageChangeListener(new OnCalendarPageChangeListener() {
@Override
public void onChange() {
showToast();
}
});
calendarView.setOnPreviousPageChangeListener(new OnCalendarPageChangeListener() {
@Override
public void onChange() {
showToast();
}
});
}
private void showToast(){
// set month and year here....
Toast.makeText(getApplicationContext(),"current month " + month + " current year " + year, Toast.LENGTH_SHORT).show();
}
}
有没有办法获取当前显示的月份和年份?
Is there a way of getting the currently shown month and year?
任何帮助将不胜感激.
