增：
person = new Person();
person.setName(user);
person.setAddress(password);
person.save(new SaveListener() {
 @Override
 public void done(String s, BmobException e) {
 if(e == null){
  Toast.makeText(MainActivity.this, "成功", Toast.LENGTH_SHORT).show();
 }
 else{
 }
 }
});
删
Id可以通过查处所有的，从而得到id
id=list.get(i).getObjectId();
 person = new Person();
person.delete(id, new UpdateListener() {
 @Override
 public void done(BmobException e) {
 if(e==null){
 Log.e("sss","删除成功"); }
 }
 });
查 ：和上面的查不大一样，这也是一种方法
//查询所有，
query.findObjects(new FindListener() {
 @Override
 public void done(List list, BmobException e) {
}}
//查询单个
query.getObject(id，new listener)
改
person.setName(“111”);
person.update(id,new UpdateListener() {
    @Override
    public void done(BmobException e) {
     if(e==null){
//     Toast.makeText(MainActivity.this, "更改成功", Toast.LENGTH_SHORT).show();
     Log.e("sss","更改成功");
     }
    }
