kotlin - Kotlin HTTP GET 数据并插入到 textView

问题描述

嘿开发人员，我在 Kotlin for Android 中找到一种方法来获取 HTTP 数据并将其插入 textView 时遇到问题。

   val HTTPget = findViewById<View>(R.id.buttonPOst) as Button
    HTTPget.setOnClickListener{

        val t = findViewById<View>(R.id.editTextTextPersonName) as EditText
        val result = URL(t.toString()).readText()


        // Device 1
        val net1 = findViewById<TextView>(R.id.textViewzx)
        GlobalScope.launch {
            val adid = result.toString()
            Log.e("MainActivity","ADID="+adid)
            withContext(Dispatchers.Main){
                net1.setText(adid)
            }
        }

我认为 URL(t.toString()).readText() 是正确的方法，但它给了我这个错误代码：

我应该使用 okhttp 库吗？但我想要一个非常简单的方法来做到这一点。

解决方案

我认为您缺少从人名字段中获取文本的信息，请尝试以下代码

 val HTTPget = findViewById<View>(R.id.buttonPOst) as Button
HTTPget.setOnClickListener{

    val t = findViewById<View>(R.id.editTextTextPersonName) as EditText
    val result = URL(t.text.toString()).readText() //here change


    // Device 1
    val net1 = findViewById<TextView>(R.id.textViewzx)
    GlobalScope.launch {
        val adid = result.toString()
        Log.e("MainActivity","ADID="+adid)
        withContext(Dispatchers.Main){
            net1.setText(adid)
        }
    }
