我有材料日曆照片喜歡這張如何設置顏色的材料日曆視圖中選擇日期
private RecyclerView recycler_month_event_lists;
private FirebaseRecyclerAdapter adapter;
,我已經指派像這樣
recycler_month_event_lists = (RecyclerView) view.findViewById(R.id.event_recycler_view);
calendar_view = (MaterialCalendarView) view.findViewById(R.id.calendar_view);
和我列出我的各個事件通過FirebaseRecyclerAdapater月這樣
recycler_month_event_lists.setLayoutManager(new LinearLayoutManager(getActivity()));
adapter = new FirebaseRecyclerAdapter<Event, EventViewHolder>(Event.class, R.layout.row_event_list,
EventViewHolder.class, mRef.child("events").child("1").child(month)) {
@Override
protected void populateViewHolder(EventViewHolder viewHolder, Event model, int position) {
List<CalendarDay> list = new ArrayList<CalendarDay>();
ArrayList<Integer> day = model.getDate();
ArrayList<Date> markedDates = new ArrayList<>();
Calendar calendar = Calendar.getInstance();
//generating ArrayList<Date>
for (int i = 0; i < day.size(); ++i) {
Calendar cal = Calendar.getInstance();
Integer year = cal.get(Calendar.YEAR);
cal.set(Calendar.YEAR, year);
cal.set(Calendar.DAY_OF_MONTH, day.get(i));
cal.set(Calendar.MONTH, Integer.valueOf(month));
Date newdate = cal.getTime();
markedDates.add(newdate);
}
//adding those generated ArrayList<Dates> in List<CalendarDays>
for (Date date : markedDates) {
// might be a more elegant way to do this part, but this is very explicit
int year = date.getYear();
int month = date.getMonth() -1; // months are 0-based in Calendar
int newday = date.getDay();
calendar.set(year, month, newday);
CalendarDay calendarDay = CalendarDay.from(calendar);
list.add(calendarDay);
}
//adding list of CalendarDays
calendarDays = list;
//code to decorate selected dates
calendar_view.addDecorators(new EventDecorator(Color.parseColor("#00ff00"), calendarDays));
if (!day.isEmpty()) {
for(int i = 0; i < day.size();i++){
int z = i+1;
if(i == 0){
from = "From"+ " " +day.get(i);
}
if(z == day.size()){
to = "to"+ " " +day.get(i);
}
}
}
viewHolder.ev_title.setText(model.getTitle());
viewHolder.ev_description.setText(model.getDescription());
viewHolder.ev_date.setText(from + " " + to);
Glide.with(getActivity()).load(model.getIcon()).into(viewHolder.ev_image);
}
};
recycler_month_event_lists.setAdapter(adapter);
}
這裏的ArrayList天= model.getDate();返回需要着色的日子。一天的日誌是這樣
D/arra: [1, 2, 3]
我跟着堆棧的答案之一,但我可以讓我的日期有色我不知道什麼是錯我的代碼。 我用
calendar_view.addDecorators(new EventDecorator(Color.parseColor("#00ff00"), calendarDays));
裝飾選擇天 我EventDecorator是這樣
public class EventDecorator implements DayViewDecorator {
private final int color;
private final HashSet<CalendarDay> dates;
public EventDecorator(int color, Collection<CalendarDay> dates) {
this.color = color;
this.dates = new HashSet<>(dates);
}
@Override
public boolean shouldDecorate(CalendarDay day) {
return dates.contains(day);
}
@Override
public void decorate(DayViewFacade view) {
view.addSpan(new DotSpan(5, color));
}
}
而且我CalendarDays是這樣
private Collection<CalendarDay> calendarDays = new Collection<CalendarDay>() {
@Override
public boolean add(CalendarDay object) {
return false;
}
@Override
public boolean addAll(Collection<? extends CalendarDay> collection) {
return false;
}
@Override
public void clear() {
}
@Override
public boolean contains(Object object) {
return false;
}
@Override
public boolean containsAll(Collection<?> collection) {
return false;
}
@Override
public boolean isEmpty() {
return false;
}
@NonNull
@Override
public Iterator<CalendarDay> iterator() {
return null;
}
@Override
public boolean remove(Object object) {
return false;
}
@Override
public boolean removeAll(Collection<?> collection) {
return false;
}
@Override
public boolean retainAll(Collection<?> collection) {
return false;
}
@Override
public int size() {
return 0;
}
@NonNull
@Override
public Object[] toArray() {
return new Object[0];
}
@NonNull
@Override
public <T> T[] toArray(T[] array) {
return null;
}
};
任何幫助,將不勝感激。先謝謝了。
我在最後一段感到困惑。你的意思是在EventDecorator中傳遞的CalendarDays應該有相應的月份和年份的正確日期 –
偉大的兄弟你的最後一段解決了我的問題。上面的代碼也可以工作,但不是我想要的。問題是getYear()方法並沒有退休。多謝兄弟 –
