将一天的日历事件获取到 android 应用程序中

Question

我想知道如何从特定日期的日历中获取事件我只想阅读所选日期的事件？

这样读取所有日历事件：

while (cur.moveToNext()) {
    String title = null;
    long eventID = 0;
    long beginVal = 0;    

    // Get the field values
    eventID = cur.getLong(PROJECTION_ID_INDEX);
    beginVal = cur.getLong(PROJECTION_BEGIN_INDEX);
    title = cur.getString(PROJECTION_TITLE_INDEX);

    // Do something with the values. 
    Log.i(DEBUG_TAG, "Event:  " + title); 
    Calendar calendar = Calendar.getInstance();
    calendar.setTimeInMillis(beginVal);  
    DateFormat formatter = new SimpleDateFormat("MM/dd/yyyy");
    Log.i(DEBUG_TAG, "Date: " + formatter.format(calendar.getTime()));    
    }
 }

您应该在查询中使用selection 按开始日期过滤事件。例如。

Calendar calendar = Calendar.getInstance();
calendar.set(2014, Calendar.MAY, 14, 0, 0, 0);
long startDay = calendar.getTimeInMillis();
calendar.set(2014, Calendar.MAY, 14, 23, 59, 59);
long endDay = calendar.getTimeInMillis();

String[] projection = new String[] { BaseColumns._ID, CalendarContract.Events.TITLE, CalendarContract.Events.DTSTART };
String selection = CalendarContract.Events.DTSTART + " >= ? AND " + CalendarContract.Events.DTSTART + "<= ?";
String[] selectionArgs = new String[] { Long.toString(startDay), Long.toString(endDay) }; 

Cursor cur = getContentResolver().query(CalendarContract.Events.CONTENT_URI, projection, selection, selectionArgs, null);
