删除日历条目

问题描述

我写了简单的code删除从Android的日历中的所有条目，但它并没有删除什么。

来源$ C ​​$ C：

 公共无效DeleteEvent（查看视图）{

            INT iNumRowsDeleted = 0;
            乌里eventsUri = Uri.parse（内容：//com.android.calendar/events）;
            光标CUR = getContentResolver（）查询（eventsUri，NULL，NULL，NULL，NULL）;

            而（cur.moveToNext（））{

                长ID = cur.getLong（cur.getColumnIndex（_ ID））;
                Log.d（TAG，ID：+ ID）;
                乌里eventUri = ContentUris.withAppendedId（eventsUri，ID）;
                。iNumRowsDeleted = getContentResolver（）删除（eventUri，NULL，NULL）;
            }
        }
 

解决方案

我使用它进行删除：

 私人无效deleteEvent（ContentResolver的解析器，乌里eventsUri，诠释calendarId）{
    光标光标;
    如果（android.os.Build.VERSION.SDK_INT＆LT; = 7）{//先进的Andr​​oid 2.1
        光标= resolver.query（eventsUri，新的String [] {_id}，Calendars._id =+ calendarId，NULL，NULL）;
    }其他{// 8的是Android 2.2（升级Froyo）（http://developer.android.com/reference/android/os/Build.VERSION_$c$cS.html）
        光标= resolver.query（eventsUri，新的String [] {_id}，CALENDAR_ID =+ calendarId，NULL，NULL）;
    }
    而（cursor.moveToNext（））{
        长事件ID = cursor.getLong（cursor.getColumnIndex（_ ID））;
        resolver.delete（ContentUris.withAppendedId（eventsUri，事件ID），NULL，NULL）;
    }
    cursor.close（）;
}
 

我把它的东西是这样的：

 乌里eventsUri;
INT OSVERSION = android.os.Build.VERSION.SDK_INT;
如果（OSVERSION＆LT; = 7）{//先进的Andr​​oid 2.1
    eventsUri = Uri.parse（内容：//日历/事件）;
}其他{// 8的是Android 2.2（升级Froyo）（http://developer.android.com/reference/android/os/Build.VERSION_$c$cS.html）
    eventsUri = Uri.parse（内容：//com.android.calendar/events）;
}
ContentResolver的解析器= this.getContentResolver（）;
deleteEvent（解析器，eventsUri，calendarId）;
 

I wrote simple code for deleting all entries from android calendar,but it didn't delete nothing.

Source code:

public void DeleteEvent(View view){

            int iNumRowsDeleted = 0;
            Uri eventsUri = Uri.parse("content://com.android.calendar/events");
            Cursor cur = getContentResolver().query(eventsUri, null, null, null, null);

            while (cur.moveToNext()){

                long id = cur.getLong(cur.getColumnIndex("_id"));
                Log.d(TAG, "ID: " + id);
                Uri eventUri = ContentUris.withAppendedId(eventsUri, id);
                iNumRowsDeleted = getContentResolver().delete(eventUri, null, null);
            }
        }

解决方案

I use this for delete:

private void deleteEvent(ContentResolver resolver, Uri eventsUri, int calendarId) {
    Cursor cursor;
    if (android.os.Build.VERSION.SDK_INT <= 7) { //up-to Android 2.1
        cursor = resolver.query(eventsUri, new String[]{ "_id" }, "Calendars._id=" + calendarId, null, null);
    } else { //8 is Android 2.2 (Froyo) (http://developer.android.com/reference/android/os/Build.VERSION_CODES.html)
        cursor = resolver.query(eventsUri, new String[]{ "_id" }, "calendar_id=" + calendarId, null, null);
    }
    while(cursor.moveToNext()) {
        long eventId = cursor.getLong(cursor.getColumnIndex("_id"));
        resolver.delete(ContentUris.withAppendedId(eventsUri, eventId), null, null);
    }
    cursor.close();
}

I call it with something like this:

Uri eventsUri;
int osVersion = android.os.Build.VERSION.SDK_INT;
if (osVersion <= 7) { //up-to Android 2.1
    eventsUri = Uri.parse("content://calendar/events");
} else { //8 is Android 2.2 (Froyo) (http://developer.android.com/reference/android/os/Build.VERSION_CODES.html)
    eventsUri = Uri.parse("content://com.android.calendar/events");
}
ContentResolver resolver = this.getContentResolver();
deleteEvent(resolver, eventsUri, calendarId);
