CalendarView getDate方法返回当前日期,而不是所选日期。。。我做错了什么?

我的日历视图无法返回所选日期,而是返回一些始终指向今天的默认日期。

我当然在更改日历中选择的日期,它确实显示为已更改。我试图在调试模式下检查视图,但没有找到任何东西。

<CalendarView
                            android:id="@+id/view_calendar_create_event_date"
                            android:layout_width="wrap_content"
                            android:layout_height="0dp"
                            android:layout_weight="1" />

这是从事件侦听器调用的

protected void createEvent(View view){
        TextView eventNameView = (TextView) this.findViewById(R.id.createEventNameInput);
        String eventName = eventNameView.getEditableText().toString();

        CalendarView eventOccursOnView = (CalendarView) this.findViewById(R.id.view_calendar_create_event_date);
        long eventOccursOn = eventOccursOnView.getDate();
        Date temporary = new Date(eventOccursOn);

        Event newEvent = new Event(eventName, "", 0, 0, eventOccursOn);
        newEvent.save(view.getContext());
    }

这就是我设置事件侦听器的方式

saveButton.setOnClickListener(new View.OnClickListener(){
            @Override
            public void onClick(View view) {
                // Create the event
                EventDetailsActivity.this.createEvent(view);

                // Notify the user
                Snackbar.make(view, "Successfully created a new event!", Snackbar.LENGTH_LONG)
                        .setAction("Action", null).show();

                // Return to the previous activity
                finish();
            }
        });

您需要实施 setOnDateChangeListener

long eventOccursOn;

eventOccursOnView.setOnDateChangeListener(new OnDateChangeListener() {
    //show the selected date as a toast
    @Override
    public void onSelectedDayChange(CalendarView view, int year, int month, int day) {
        Toast.makeText(getApplicationContext(), day + "/" + month + "/" + year, Toast.LENGTH_LONG).show();
        Calendar c = Calendar.getInstance();
        c.set(year, month, day);
        eventOccursOn = c.getTimeInMillis(); //this is what you want to use later
    }
 });
