GameScore gameScore = new GameScore();
//注意：不能调用gameScore.setObjectId("")方法
gameScore.setPlayerName("比目");
gameScore.setScore(89);
gameScore.setIsPay(false);
gameScore.save(mContext, new SaveListener() {
@Override
public void onSuccess() {
    toast("添加数据成功，返回objectId为："+gameScore.getObjectId() + ”,数据在服务端的创建时间为：“ + gameScore.getCreatedAt());

BmobQuery<Comment> query = new BmobQuery<Comment>();
BmobQuery<Post> innerQuery = new BmobQuery<Post>();
innerQuery.addWhereExists("image", true);
// 第一个参数为评论表中的帖子字段名post
// 第二个参数为Post字段的表名，也可以直接用"Post"字符串的形式
// 第三个参数为内部查询条件
query.addWhereMatchesQuery("post", "Post", innerQuery);
query.findObjects(this, new FindListener<Comment>() {

public class Comment extends BmobObject {
private String comment;
private Found found;
private Lost lost;
private MyUser user;
}

bmobQuery.include("userAuthor");
bmobQuery.include("xxxxEntity");
则:
aaaaEntity.getUserAuthor.getName()返回空
如果去掉后一行
bmobQuery.include("userAuthor");
//bmobQuery.include("xxxxEntity");
或
移到后面：
bmobQuery.include("xxxxEntity");
bmobQuery.include("userAuthor");
aaaaEntity.getUserAuthor.getName() 就能正常返回值

//创建HR和Cashier两个用户角色（这里为了举例BmobRole的使用，将这段代码写在这里，正常情况下放在员工管理界面会更合适）

//将hr_zhang和hr_luo归属到hr角色中
hr.getUsers().add(hr_zhang);

hr.save(this); 
//将cashier_xie归属到cashier角色中
cashier.getUsers().add(cashier_xie);
//保存到云端角色表中（web端可以查看Role表）
cashier.save(this);

// 根据objectId查询数据

// 如下取出查询到的数据中的BmobFile类型，得到下载地址
