我正在使用CalenderView显示日期和下面的CalenderView我使用ListView来显示带有Events的日期（日）。我能够解析所有日期事件但我想要的是显示特定日特定月份下的活动。如何实现？
CalenderFragment
public class CalenderFragment extends Fragment {
CalendarView calendar;

getActivity().setTitle("");
setHasOptionsMenu(true);
calendar = (CalendarView) view.findViewById(R.id.calendar);
calendar.setOnDateChangeListener(new CalendarView.OnDateChangeListener() {
@Override
public void onSelectedDayChange(CalendarView view,
int year, int month, int dayOfMonth) {
Toast.makeText(getContext(),
dayOfMonth + "/" + month + "/" + year, Toast.LENGTH_LONG).show();
}
});
listView = (ListView) view.findViewById(R.id.calenderlist);
SessionManagement session = new SessionManagement(getContext());
session.checkLogin();
access_token = session.getAccesstToken();
makeJsonObjectRequest();
return view;
}
private void makeJsonObjectRequest() {
RequestQueue requestQueue = Volley.newRequestQueue(getContext());
String URL = Navigation_URL;
StringRequest stringRequest = new StringRequest(Request.Method.GET, URL,
new Response.Listener<String>() {
@Override
public void onResponse(String response) {
try {
ArrayList<CalenderPojoStudent> student_list_calender = new ArrayList<>();
JSONArray jArray = new JSONArray(response);
for (int i = 0; i < jArray.length(); i++) {
JSONObject jsonObject = jArray.getJSONObject(i);
String StartAt = jsonObject.getString("StartAt").substring(6,10);
String Title = jsonObject.getString("Title");
student_list_calender.add(new CalenderPojoStudent(StartAt, Title));
}
CalenderAdapter calenderAdapter = new CalenderAdapter(getActivity(), student_list_calender);
listView.setAdapter(calenderAdapter);
} catch (JSONException e) {
Toast.makeText(getContext(), "Fetch failed!", Toast.LENGTH_SHORT).show();
e.printStackTrace();
}
}
}, new Response.ErrorListener() {
@Override

如何在Calender Month的basais上的listView上显示特定月份的事件？
答案 0 :(得分：0)
您可以使用此库来显示日历中的事件.DOts将显示在日期下方。 MaterialCalendarView
搜索装饰器，你可以在该库中使用wth日期。
materialCalendarView.setDateTextAppearance()
materialCalendarView.addDecorator(new OpenSansDecorator(getActivity()));
materialCalendarView.setHeaderTextAppearance(R.style.TextAppearance_ProfileCalenderHeader);
这可以用来在日历中显示点，你可以实现一个逻辑，根据日历中的日期点击显示recylerview。
请参阅this以了解lib中的事件装饰：
