Bmob版本v3.5.6

1.添加数据

    private void addPerson() {        final Person p2 = new Person();        p2.setName("lucky");        p2.setAddress("北京市海淀区");        p2.setAge(25);        //添加Object类型        p2.setBankCard(new BankCard("哈哈", "111"));        //添加Object类型的数组        List<BankCard> cards =new ArrayList<BankCard>();        for(int i=0;i<2;i++){            cards.add(new BankCard("建行", "111"+i));        }        p2.addAll("cards", cards);        //添加String类型的数组        p2.addAll("hobby", Arrays.asList("游泳", "看书"));    // 一次添加多个值到hobby字段中//      p2.add("cards",new BankCard("建行", "111"));//一次添加单个值        p2.setGpsAdd(new BmobGeoPoint(112.934755, 24.52065));        p2.setUploadTime(new BmobDate(new Date()));        p2.save(new SaveListener<String>() {            @Override            public void done(String o, BmobException e) {                if(e==null){                    objectId = p2.getObjectId();                    toast("创建数据成功：" + p2.getObjectId());                    Log.d("bmob", "objectId = " + p2.getObjectId());                    Log.d("bmob", "name =" + p2.getName());                    Log.d("bmob", "age =" + p2.getAge());                    Log.d("bmob", "address =" + p2.getAddress());                    Log.d("bmob", "gender =" + p2.isGender());                    Log.d("bmob", "createAt = " + p2.getCreatedAt());                }else{                    loge(e);                }            }        });    }

删除数据

    private void deleteObject() {        Person p2 = new Person();        p2.removeAll("cards", Arrays.asList(new BankCard("建行", "111")));        p2.setObjectId(objectId);        p2.update(new UpdateListener() {            @Override            public void done(BmobException e) {                if(e==null){                    log("删除成功");                }else{                    loge(e);                }            }        });    }}

数据修改

    private void testUpdateObjet() {        final Person p2 = new Person();        //更新数组中的某个位置的对象值        p2.setValue("cards.0", new BankCard("cards.0", "cards.0的值"));        //更新对象数组中指定对象的指定字段的值//      p2.setValue("cards.0.bankName", "银行卡");//      p2.setValue("cards.0.cardNumber", "卡号");//      p2.setValue("cards.1.bankName", "银行卡");        //更新BmobObject的值//      p2.setValue("author", BmobUser.getCurrentUser(this, MyUser.class));        //更新Object类型的数组//      List<BankCard> cards =new ArrayList<BankCard>();//      for(int i=0;i<2;i++){//          cards.add(new BankCard("叫姐姐"+i, "111"+i));//      }//      p2.setValue("cards",cards);        //更新Object对象        p2.setValue("bankCard",new BankCard("bankCard", "bankCard的值"));        //更新Object对象的值//      p2.setValue("bankCard.bankName","你妹");        //更新Integer类型//      p2.setValue("age",11);//      p2.setValue("gender", true);        p2.update(objectId, new UpdateListener() {            @Override            public void done(BmobException e) {                if(e==null){                    log("更新成功：" + p2.getUpdatedAt());                }else{                    loge(e);                }            }        });    }
