android - 如何自动将事件添加到日历？

Question

我如何自动将事件添加到日历？如果我使用此源代码，它会打开带有填充条目的日历，但我必须单击“保存”按钮才能保存它。

public class CalendarApplicationActivity extends Activity
{  

public static final String[] EVENT_PROJECTION = new String[] 
{  
        Calendars._ID, // 0  
        Calendars.ACCOUNT_NAME, // 1  
        Calendars.CALENDAR_DISPLAY_NAME // 2  
};  


private static final int PROJECTION_DISPLAY_NAME_INDEX = 2;  

@Override 
public void onCreate(Bundle savedInstanceState)
{  
    super.onCreate(savedInstanceState);  
    setContentView(R.layout.activity_calendar_application);  
}  

public void onClick(View view) 
{  

    Intent intent = new Intent(Intent.ACTION_INSERT);  
    intent.setType("vnd.android.cursor.item/event");  
    intent.putExtra(Events.TITLE, "Learn Android");  
    intent.putExtra(Events.EVENT_LOCATION, "Home suit home");  
    intent.putExtra(Events.DESCRIPTION, "Download Examples");  

    GregorianCalendar calDate = new GregorianCalendar(2012, 10, 02);  
    intent.putExtra(CalendarContract.EXTRA_EVENT_BEGIN_TIME,  
            calDate.getTimeInMillis());  
    intent.putExtra(CalendarContract.EXTRA_EVENT_END_TIME,  
            calDate.getTimeInMillis());  

    intent.putExtra(CalendarContract.EXTRA_EVENT_ALL_DAY, true);  


    intent.putExtra(Events.ACCESS_LEVEL, Events.ACCESS_PRIVATE);  
    intent.putExtra(Events.AVAILABILITY, Events.AVAILABILITY_BUSY);  

    startActivity(intent);  

}  


}

我向您发布了我在市场上的一个应用程序中使用的代码。它会自动将事件添加到用户日历中。它不使用需要用户操作的 Intent。

public void addEvent(CalendarEvent evt) {
    //Log.d(Params.LOG_APP, "Insert event ["+evt+"]");

    try {
        Uri evtUri = ctx.getContentResolver().insert(getCalendarUri("events"), CalendarEvent.toContentValues(evt));
        Log.d(Params.LOG_APP, "" + evtUri);
    }
    catch(Throwable t) {
        //Log.e(Params.LOG_APP, "", t);
    }
}

public void setContext(Context context) {
    this.ctx = context;
    this.baseUri = getCalendarUriBase();
}

private Uri getCalendarUri(String path) {
    return Uri.parse(baseUri + "/" + path);
}

private String getCalendarUriBase() {
    String calendarUriBase = null;
    Uri calendars = Uri.parse("content://calendar/calendars");
    Cursor managedCursor = null;
    try {
        managedCursor = ctx.getContentResolver().query(calendars, null, null, null, null);
    } catch (Exception e) {
       // e.printStackTrace();
    }

    if (managedCursor != null) {
        calendarUriBase = "content://calendar/";
    } else {
        calendars = Uri.parse("content://com.android.calendar/calendars");
        try {
            managedCursor = ctx.getContentResolver().query(calendars, null, null, null, null);
        } catch (Exception e) {
           // e.printStackTrace();
        }

        if (managedCursor != null) {
            calendarUriBase = "content://com.android.calendar/";
        }

    }

    Log.d(Params.LOG_APP, "URI ["+calendarUriBase+"]");
    return calendarUriBase;
}

对于 ICS 及更高版本

public void addEvent(CalendarEvent evt) {

    ContentResolver cr = context.getContentResolver();
    Uri uri = cr.insert(Events.CONTENT_URI, CalendarEvent.toICSContentValues(evt));
    System.out.println("Event URI ["+uri+"]");

}

CalendarEvent 就像

public static ContentValues toContentValues(CalendarEvent evt) {
    ContentValues cv = new ContentValues();
    cv.put("calendar_id", evt.getIdCalendar());
    cv.put("title", evt.getTitle());
    cv.put("description", evt.getDescr());
    cv.put("eventLocation", evt.getLocation());
    cv.put("dtstart", evt.getStartTime());
    cv.put("dtend", evt.getEndTime());
    cv.put("eventStatus", 1);
    cv.put("visibility", 0);
    cv.put("transparency", 0);

    return cv;

}

public static ContentValues toICSContentValues(CalendarEvent evt) {

    ContentValues cv = new ContentValues();
    cv.put(Events.CALENDAR_ID, evt.getIdCalendar());
    cv.put(Events.TITLE, evt.getTitle());
    cv.put(Events.DESCRIPTION, evt.getDescr());
    cv.put(Events.EVENT_LOCATION, evt.getLocation());
    cv.put(Events.DTSTART, evt.getStartTime());
    cv.put(Events.DTEND, evt.getEndTime());

    Calendar cal = Calendar.getInstance();
    TimeZone tz = cal.getTimeZone();

    cv.put(Events.EVENT_TIMEZONE, tz.getDisplayName());
    /*
    cv.put(Events.STATUS, 1);
    cv.put(Events.VISIBLE, 0);
    cv.put("transparency", 0);

    return cv;
    */

    return cv;
}
