Android sqlite cursor的遍历

查询并获得了cursor对象后，用while(corsor.moveToNext()){}遍历，当corsor.moveToNext()方法调用，如果发现没有对象，会返回false

    public List<MMImage> getAll() {

        List<MMImage> list = new ArrayList<MMImage>();

        Cursor c = null;

        try {

            c = database.query(TABLE, null, null, null, null, null, null);

            while (c.moveToNext()) {

                MMImage mmImage = getMMImageFromCursor(c);

                list.add(mmImage);

            }

        } catch (Exception e) {

            e.printStackTrace();

        } finally {

            if (c != null) {

                c.close();

            }

        }

        return list;

    }
