我在Android的Kotlin中有这段代码，我需要将append应用于messageReceived变量。我该怎么做？
private lateinit var messageReceived: TextView
this.messageReceived = findViewById(R.id.messageRreceived)
private fun updateReceivedMessage(newPayload: String) {
runOnUiThread { messageReceived.text = newPayload }
}
首先获取文本，然后设置新文本
private fun updateReceivedMessage(newPayload: String) {
runOnUiThread {
val previousText = messageReceived.text.toString()
messageReceived.text = "$previousText $newPayload"
}
}
您可以通过换行使其更具可读性
messageReceived.text = "$previousText\n$newPayload"
