原标题:Android: Accessing DB

我有以下法典:

DbAdapter dbAdapter = new DbAdapter(this);
dbAdapter.open();
ArrayList<String> queryResultList = new ArrayList<String>();
Cursor cur = dbAdapter.db.query("mytable", columns, where, null, groupBy, null, null);      
cur.moveToFirst();
while (cur.isAfterLast() == false) 
{
        queryResultList.add(cur.getString(0));
    cur.moveToNext();
}
cur.close();

dbAdapter.close();

该法典使用的是它从未运行过的一个装置,即一台wi子和三星银河S装置,在第一次审判后该装置被拆除。 这就是说,我所阅读的数据库正首先在装置上建立。 这是一个海关数据库。

2.2 它对2.1级(API第7级)获得的罚款完全有效,After Last(After Last)总是真实的,但从APIC第1级起就是如此。 任何想法? 或者我能做些什么来说明的想法?

感谢,A。

Hmm, 所以不使用:

Cursor cur = ...;
while (cur.moveToNext()) {
  queryResultList.add(cur.getString(0));
}
cur.close();
