在 Android 4.0 中添加日历和事件

Question

我想在 android 4.0 及以上版本的设备中添加日历事件。 目前我正在使用以下代码添加事件，

if (android.os.Build.VERSION.SDK_INT <= 7 )
                    {
                        Uri calendars = Uri.parse("content://calendar/calendars");
                        Cursor managedCursor = managedQuery(calendars, projection, null, null, null);
                        if (managedCursor.moveToFirst()) 
                        {
                            String calName; 
                            String calId; 
                            int nameColumn = managedCursor.getColumnIndex("name"); 
                            int idColumn = managedCursor.getColumnIndex("_id");
                            do 
                            {
                                calName = managedCursor.getString(nameColumn);
                                calId = managedCursor.getString(idColumn);
                                Log.e("Calendar Id : ",""+calId+" : "+calName);
                            }
                            while (managedCursor.moveToNext());

                            if(calId != null)
                            {
                                try 
                                {
                                    Log.e("Calendar Id : ",""+calId+" : "+calName);
                                    ContentValues event = new ContentValues();
                                    event.put("calendar_id", calId);
                                    event.put("title", summary);
                                    event.put("description", summary);
                                    event.put("eventLocation", "");

                                    event.put("dtstart", startTime);
                                    event.put("dtend", endTime);
                                    event.put("allDay", allDayFlag);  
                                    event.put("eventStatus", 1);
                                    event.put("visibility", 0);
                                    event.put("hasAlarm", 1); 
                                    Uri eventsUri = Uri.parse("content://calendar/events");
                                    Uri url = getContentResolver().insert(eventsUri, event);
                                    Log.e("Event Res : ",""+url);
                                    if(!url.equals(""))
                                    Main.showErrorDialog(this, "Event Successfully Added ");
                                }
                                catch (Exception kwse) 
                                {
                                    Log.e("Exception 1 kwse ",""+kwse.toString());
                                }
                            }
                        }
                    }
                    else
                    {
                        Uri calendars= Uri.parse("content://com.android.calendar/calendars");
                        Cursor managedCursor = managedQuery(calendars, projection, null, null, null);
                        if (managedCursor.moveToFirst()) 
                        {
                            String calName; 
                            String calId; 
                            int nameColumn = managedCursor.getColumnIndex("name"); 
                            int idColumn = managedCursor.getColumnIndex("_id");
                            do 
                            {
                                calName = managedCursor.getString(nameColumn);
                                calId = managedCursor.getString(idColumn);
                                Log.e("Calendar Id : ",""+calId+" : "+calName);
                            }
                            while (managedCursor.moveToNext());

                            if(calId != null)
                            {
                                try 
                                {
                                    Log.e("Calendar Id : ",""+calId+" : "+calName);
                                    ContentValues event = new ContentValues();
                                    event.put("calendar_id", calId);
                                    event.put("title", summary);
                                    event.put("description", summary);
                                    event.put("eventLocation", "");

                                    event.put("dtstart", startTime);
                                    event.put("dtend", endTime);
                                    event.put("allDay", allDayFlag);  
                                    event.put("eventStatus", 1);
                                    event.put("visibility", 0);
                                    event.put("hasAlarm", 1); 
                                    Uri eventsUri = Uri.parse("content://com.android.calendar/events");
                                    Uri url = getContentResolver().insert(eventsUri, event);
                                    Log.e("Event Res : ",""+url);
                                    if(!url.equals(""))
                                    Main.showErrorDialog(this, "Event Successfully Added ");
                                }
                                catch (Exception kwse) 
                                {
                                    Log.e("Exception 2 kwse ",""+kwse.toString());
                                }
                            }
                        }
                    }

上面的代码在 android 3.0 之前运行良好，但是在 android 4.0 中没有添加事件，这是我从客户那里收到的投诉。我没有android 4.0的设备，所以无法查看。

对于sdk version 7 and below 的安卓设备，我们使用它作为

Uri calendars = Uri.parse("content://calendar/calendars");

sdk version above 7 我们使用 as

Uri calendars= Uri.parse("content://com.android.calendar/calendars");

这对于 android 4.0 也是一样的吗？有什么要改变的吗？

Answer 1

我认为 Android 4.0 中不存在“可见性”

和

int nameColumn = managedCursor.getColumnIndex("calendar_displayName");

可能比

int nameColumn = managedCursor.getColumnIndex("name");

Answer 2

我也遇到了同样的问题及其解决方案。我的事件没有添加到 ICS 和 JellyBean 设备中，而是适用于所有其他设备。
试试这个 -

ContentValues event = new ContentValues();
int apiLevel = android.os.Build.VERSION.SDK_INT;
            if(apiLevel<14)
            event.put("visibility", 0);

仅当设备版本低于 14(ICS) 时才使用可见性

在 ICS 中，您必须使用公共日历 API。请检查以下链接：
