android - RecyclerView 交换两个适配器

问题描述

我想制作一个使用 API 显示最后 15 场比赛和接下来 15 场比赛的应用程序。我创建了一个具有 2 个不同列表视图的 RecyclerView。一个用于最后一场比赛，另一个用于下一场比赛。我还创建了 2 个不同的适配器，所以当我单击不同的导航栏时，它会将视图（例如最后一个匹配）更改为另一个视图（下一个匹配）。但是，当我单击第二个按钮（下一个匹配项）时，它强制停止。

我认为问题出在适配器集中，但我不知道在哪里

这是我的代码：

MainActivity.kt

private val mOnNavigationItemSelectedListener = BottomNavigationView.OnNavigationItemSelectedListener { item ->
    when (item.itemId) {
        R.id.navigation_home -> {
            //Prev Match
            recyclerView_main.layoutManager = LinearLayoutManager(this)
            fetchJsons()
            return@OnNavigationItemSelectedListener true
        }
        R.id.navigation_dashboard -> {
            //Next Match
            recyclerView_main.layoutManager = LinearLayoutManager(this)
            fetchJson()
            return@OnNavigationItemSelectedListener true
        }
    }
    false
}
fun fetchJsons(){
    //Json for prev match
    val url = "https://www.thesportsdb.com/api/v1/json/1/eventspastleague.php?id=4328"
    val request = Request.Builder().url(url).build()
    val client = OkHttpClient()
    client.newCall(request).enqueue(object: Callback{
        override fun onResponse(call: Call?, response: Response?){
            println("sukses")
            val body = response?.body()?.string()
            println(body)

            val gson = GsonBuilder().create()

            val prevMatch = gson.fromJson(body, PrevMatch::class.java)

            runOnUiThread { recyclerView_main.adapter = MainAdapters(prevMatch) }
        }
        override fun onFailure(call: Call?, e: IOException?){
            println("failed request")
        }
    })
}

// Next Match JSON
fun fetchJson(){
    val url = "https://www.thesportsdb.com/api/v1/json/1/eventsnextleague.php?id=4328"
    val request = Request.Builder().url(url).build()
    val client = OkHttpClient()
    client.newCall(request).enqueue(object: Callback{
        override fun onResponse(call: Call?, response: Response?){
            println("sukses")
            val body = response?.body()?.string()
            println(body)

            val gson = GsonBuilder().create()

            val nextMatch = gson.fromJson(body, NextMatch::class.java)

            runOnUiThread { recyclerView_main.adapter = MainAdapter(nextMatch) }
        }
        override fun onFailure(call: Call?, e: IOException?){
            println("failed request")
        }
    })
}

解决方案

这就是我要做的，我将创建两个 recyclerView 并在它们之间切换。并在它们之间划分来自 API 的数据。

private val mOnNavigationItemSelectedListener = BottomNavigationView.OnNavigationItemSelectedListener { item ->
        when (item.itemId) {
            R.id.navigation_home -> {
                //Prev Match
                recyclerView_Next_Match.visibility = View.GONE
                recyclerView_Prev_Match.visibility = View.VISIBLE
                fetchJsons()
                return@OnNavigationItemSelectedListener true
            }
            R.id.navigation_dashboard -> {
                //Next Match
                recyclerView_Prev_Match.visibility = View.GONE
                recyclerView_Next_Match.visibility = View.VISIBLE
                fetchJson()
                return@OnNavigationItemSelectedListener true
            }
        }
        false
    }
