解决方案
一旦用户模型被配置文件细节填充b 
 $ b 
 映射< String，Object> childUpdates = new HashMap<>（）; 
 
 myRef = database.getReference（parent_node ** strong text ** name）。child（user_profile_id）; 
 
 myRef.child（user_profile_id）.push（）; 
 
 childUpdates.put（user_profile_id，usermodel）; 
 
 myRef.updateChildren（childUpdates）; 
  
以上代码生成具有用户标识的父节点，并将用户模型保存为该标识的值（即用户ID），稍后您可以通过在Firebase数据库中调用userid作为键来获取这些配置文件的详细信息。

Can anyone tell me what I am doing wrong. 
Thank you in advance
解决方案
once user model gets filled by the profile details (feilds)
Map<String, Object> childUpdates = new HashMap<>();

myRef = database.getReference("parent_node**strong text**name").child(user_profile_id);

myRef.child(user_profile_id).push();

childUpdates.put(user_profile_id, usermodel);

myRef.updateChildren(childUpdates);
The above code generates parent node with user id and  the user model gets saved as a value for that id(i.e user id) , you may later fetch those profile details by calling userid as a key in the Firebase Database 

Hope it helps :)
