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;
    }
