为什么我的应用程序将其数据发送到另一个Firebase实时数据库

问题描述

我制作了一个新的模型应用程序（ ManualRecyclerView ），以测试如何在RecyclerView-GridView中获取数据 Firebase实时数据库。

因此，我注入了依赖性并将应用程序连接到Firebase。

我为适配器设置了基本的用户界面和代码。

但是！一旦测试并输入数据，数据就会转到另一个Firebase数据库（ Sweet Dreams ）。哪个是我正在进行的其他项目的数据库。

令我困扰的是，我已经更正了.json文件

.json文件

主要活动

package dcbrh.ph.manualrecyclerview

import androidx.appcompat.app.AppCompatActivity
import android.os.Bundle
import android.util.Log
import android.widget.Toast
import com.google.firebase.auth.FirebaseAuth
import com.google.firebase.database.FirebaseDatabase
import kotlinx.android.synthetic.main.activity_main.*

class MainActivity : AppCompatActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)

        recyclerView_main.adapter = MainAdapter()

        button_storeMovie_main.setOnClickListener {
            Log.d("MainActivity","Storing data in FirebaseDatabase")
            Toast.makeText(this,"Storing data...",Toast.LENGTH_SHORT).show()
            storeMovieInFirebaseDatabase()
        }
    }

    private fun storeMovieInFirebaseDatabase() {
        val uid = FirebaseAuth.getInstance().uid.toString()
        val title = editText_inputTitle_main.text.toString()
        val price = editText_inputPrice_main.text.toString()
        val movieData = Movie(title,price)
        FirebaseDatabase.getInstance().getReference("movies/$uid/").setValue(movieData)
            .addOnSuccessListener {
                Log.d("MainActivity","Data stored successfully | UID = $uid")
                Toast.makeText(this,"Data stored successfully",Toast.LENGTH_SHORT).show()
                return@addOnSuccessListener
            }
            .addOnFailureListener{
                Log.d("MainActivity","Data failed to store")
                Toast.makeText(this,"Data failed to store",Toast.LENGTH_SHORT).show()
                return@addOnFailureListener
            }

    }
}

class Movie(val name: String,val price: String) {
    constructor(): this("","")
}

主适配器

package dcbrh.ph.manualrecyclerview

import android.view.LayoutInflater
import android.view.View
import android.view.ViewGroup
import androidx.recyclerview.widget.RecyclerView
import kotlinx.android.synthetic.main.card_view_layout.view.*

class MainAdapter: RecyclerView.Adapter<CustomViewHolder>() {

    val productTitles = listOf("The Bird Box","Extraction","Bad Boys","300 Spartans","Project X")

    override fun getItemCount(): Int {
        return productTitles.size
    }

    override fun onCreateViewHolder(parent: ViewGroup,viewType: Int): CustomViewHolder {
        val layoutInflater = LayoutInflater.from(parent.context)
        val cellGrid = layoutInflater.inflate(R.layout.card_view_layout,parent,false)
        return CustomViewHolder(cellGrid)
    }

    override fun onBindViewHolder(holder: CustomViewHolder,position: Int) {
        val productTitles = productTitles.get(position)
        holder.sight.apply {
            cardView_textView_title.text = productTitles
            cardView_textView_price.text = "Php20.00"
        }

    }
}

class CustomViewHolder(val sight: View): RecyclerView.ViewHolder(sight) {

}

样机应用 ManualRecyclerView App

Sweet Dreams数据库 database

没有人被发送到ManualRecyclerView数据库。

解决方法

如果我理解正确，则似乎您在两个Android Studio项目中都使用了相同的Firebase项目。因此，请仔细检查您的Firebase项目结构
