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。
希望这有助于:)

Can anyone tell me what I am doing wrong. Thank you in advance
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 :)
