我正在编写一个Android应用程序，其中有不同的用户，用户可以属于一个组，并且可以选择查看共享日历。我可以使用MySQL，SQLite和PHP存储用户的信息以及他们的组名。我希望同一组的成员共享相同的日历，并希望不同的组具有不同的日历。目前，每个用户都看到相同的日历。我正在使用ExtendedCalendarView库：https://github.com/tyczj/ExtendedCalendarView 。如何为不同的组存储不同的日历？
这是我日历的java代码：
public class EventCalendar extends ListActivity {
public Day clickedDay;
ArrayList itemsList;
ExtendedCalendarView calendar;
ListView listViewCalendar;
Context context = this;
private EventAdapter eventAdapter;
Dialog dialog;
EditText eventTitle;
EditText eventDescription;
EditText startTime;
EditText endTime;
Button cancelButton;
Button submitButton;
private int hour;
private int minute;
private int startHour;
private int startMinute;
private int endHour;
private int endMinute;
private boolean startTimeSelected;
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_event_calendar);
System.out.println("August : " + Calendar.AUGUST);
listViewCalendar = getListView();
calendar = (ExtendedCalendarView)findViewById(R.id.calendar);
calendar.setGesture(ExtendedCalendarView.LEFT_RIGHT_GESTURE);
calendar.setOnDayClickListener(new ExtendedCalendarView.OnDayClickListener() {
int i = 0;
@Override
public void onDayClicked(AdapterView<?> adapter, View view, int position, long id, Day day) {
clickedDay = day;
getScheduleDetails(day);
eventAdapter = new EventAdapter(context, R.layout.calendar_event, itemsList);
listViewCalendar.setAdapter(eventAdapter);
i++;
Handler handler = new Handler();
Runnable r = new Runnable() {
@Override
public void run() {
i = 0;
}
};
if (i == 1) {
//Single click
System.out.println("single click");
handler.postDelayed(r, 350);
} else if (i == 2) {
//Double click means that user wants to add a new event
System.out.println("you double clicked and the day is: " + clickedDay.getDay());
dialog = new Dialog(context);
dialog.setContentView(R.layout.event_dialog);
dialog.setTitle("Add Event");
dialog.show();
startTime = (EditText) dialog.findViewById(R.id.startTime);
endTime = (EditText) dialog.findViewById(R.id.endTime);
startTime.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
startTimeSelected = true;
setTime();
}
});
endTime.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
startTimeSelected = false;
setTime();
}
});
cancelButton = (Button) dialog.findViewById(R.id.cancel);
cancelButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
dialog.dismiss();
}
});
submitButton = (Button) dialog.findViewById(R.id.submitEvent);
submitButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
System.out.println("adding new event");
eventTitle = (EditText) dialog.findViewById(R.id.title);
eventDescription = (EditText) dialog.findViewById(R.id.description);
startTime = (EditText) dialog.findViewById(R.id.startTime);
endTime = (EditText) dialog.findViewById(R.id.endTime);
addEvent(eventTitle.getText().toString(), eventDescription.getText().toString(), clickedDay.getYear(), clickedDay.getMonth(), clickedDay.getDay(),
startHour, startMinute, endHour, endMinute);
dialog.dismiss();
calendar.refreshCalendar();
}
});
i = 0;
}
}
});
//Clear database
//System.out.println("Rows deleted" + getContentResolver().delete(CalendarProvider.CONTENT_URI, null, null));
}
public void addEvent(String eventTitle, String eventDescription, int year, int month, int day, int sHour, int sMinute, int eHour, int eMinute) {
// Adding events
ContentValues values = new ContentValues();
values.put(CalendarProvider.COLOR, Event.COLOR_BLUE);
values.put(CalendarProvider.DESCRIPTION, eventDescription);
values.put(CalendarProvider.EVENT, eventTitle);
System.out.println("Event title: " + eventTitle);
System.out.println("Event description: " + eventDescription);
System.out.println("Year: " + year);
System.out.println("Month: " + month);
System.out.println("Day: " + day);
System.out.println("Start hour: " + sHour);
System.out.println("Start minute: " + sMinute);
System.out.println("End hour: " + eHour);
System.out.println("End minute: " + eMinute);
Calendar cal = Calendar.getInstance();
TimeZone tz = TimeZone.getDefault();
cal.set(year, month, day, sHour, sMinute);
int julianDay = Time.getJulianDay(cal.getTimeInMillis(), TimeUnit.MILLISECONDS.toSeconds((tz.getOffset(cal.getTimeInMillis()))));
values.put(CalendarProvider.START, cal.getTimeInMillis());
values.put(CalendarProvider.START_DAY, julianDay);
cal.set(year, month, day, eHour, eMinute);
int endDayJulian = Time.getJulianDay(cal.getTimeInMillis(),TimeUnit.MILLISECONDS.toSeconds(tz.getOffset(cal.getTimeInMillis())));
values.put(CalendarProvider.END, cal.getTimeInMillis());
values.put(CalendarProvider.END_DAY, endDayJulian);
Uri uri = getContentResolver().insert(CalendarProvider.CONTENT_URI,values);
System.out.println("Event added");
}
public void setTime() {
Calendar myCurrentTime = Calendar.getInstance();
hour = myCurrentTime.get(Calendar.HOUR_OF_DAY);
minute = myCurrentTime.get(Calendar.MINUTE);
TimePickerDialog myTimePicker;
myTimePicker = new TimePickerDialog(context, new TimePickerDialog.OnTimeSetListener() {
@Override
public void onTimeSet(TimePicker timePicker, int selectedHour, int selectedMinute) {
if (startTimeSelected) {
startHour = selectedHour;
startMinute = selectedMinute;
startTime.setText(selectedHour + ":" + selectedMinute);
} else {
endHour = selectedHour;
endMinute = selectedMinute;
endTime.setText(selectedHour + ":" + selectedMinute);
}
}
}, hour, minute, true);
myTimePicker.setTitle("Select start time");
myTimePicker.show();
}
private void getScheduleDetails(Day day) {
itemsList = new ArrayList();
for (Event e : day.getEvents()) {
System.out.println("Event description: " + e.getDescription());
itemsList.add(e);
}
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_event_calendar, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}
这是我的xml文件的一部分：
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<com.tyczj.extendedcalendarview.ExtendedCalendarView
android:id="@+id/calendar"
android:layout_height="380dp"
android:layout_width="match_parent" />
<ListView
android:id="@+id/android:list"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:dividerHeight="1px"/>
感谢您的时间。
