Kotlin HTTP GET 数据并插入到文本视图中

Question

嘿，开发人员，我有一个问题，在Kotlin为Android找到一种方法来获取HTTP数据，并将其插入到textView

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()是正确的方式，但它给了我这个错误代码:

我应该使用okhttp库吗?但是我想要一个非常简单的方法。

我认为你错过了从人名字段获取文本尝试下面的代码

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)
}
}
