我在我的Sqlite DB中运行查询..
我将结果保存在我的Cursor中,并且我正在迭代它以获得所有结果..
allotugh我正在检查并看到光标有超过1行,它只给我第一行,因为moveToNext()总是返回false ..
这是我的迭代代码:
Cursor cursor = getEventsDetails(db, selection, null);
Log.e("cursor before", "count" + cursor.getCount());
boolean moveToNext = cursor.moveToFirst();
if (moveToNext)
{
do
{
//Create a new PicoEvent instance with the event's details
PicoEvent event = PicoEventCreator.createPicoEvent(cursor);
Log.e(event.getName(), event.getStartTime().toLocaleString());
Log.e("cursor in", "count" + cursor.getCount());
moveToNext = cursor.moveToNext();
Log.e("moveToNext", "move: " + moveToNext);
if (!isEventExists(eventsList, event))
eventsList.add(event);
} while (moveToNext);
}
这是Logcat Debug:
12-01 17:33:07.774: E/cursor before(5950): count4
12-01 17:33:08.094: E/Pico Demo Event(5950): 1 בדצמ 2013 11:00:00
12-01 17:33:08.124: E/cursor in(5950): count4
12-01 17:33:08.124: E/moveToNext(5950): move: false
正如你所看到的行数是4,但这一举动是假的......
答案 0 :(得分:1)
您正在将此Cursor
传递给此调用中的另一个方法:
PicoEvent event = PicoEventCreator.createPicoEvent(cursor);
我敢打赌,该方法会在光标返回之前将光标推进到最后。
