    View view = inflater.inflate(R.layout.view_sos, container, false); 
    SupportMapFragment mapFragment = (SupportMapFragment)getChildFragmentManager().findFragmentById(R.id.map_report); 
    mapFragment.getMapAsync(this); 

    preferences = getActivity().getSharedPreferences(shared_preferences, Context.MODE_PRIVATE); 

    mRecyclerView = (RecyclerView)view.findViewById(R.id.rv_sos); 
    mRecyclerView.setHasFixedSize(true); 
    mLayoutManager = new LinearLayoutManager(getContext()); 


    mAuth = FirebaseAuth.getInstance(); 
    mRef = FirebaseDatabase.getInstance().getReference(); 



    mBtn = (ImageButton)view.findViewById(R.id.s_o_s_btn); 
    mBtn.setOnClickListener(this); 


       mAdapter = new FirebaseRecyclerAdapter<SOS, SoSViewHolder> 
         (
           SOS.class, 
           R.layout.sos_list, 
           SoSViewHolder.class,

         holder.setMtopic(sos.getRpTitle()); 
         holder.setMlocation(sos.getRpLocation()); 
        }

我希望每個人都能solove我的問題IM嘗試任何事情，以解決我的問題

你有不同的命名慣例你的數據庫和代碼。例如，rp_auther與rpAuther。適配器不知道如何映射這些值，這可能是空數據的原因。

您可以重命名數據庫中的屬性名稱或將@SerializedName("rp_auther")註釋添加到pojo類。
