我正在从本地服务器通过套接字接收我的图像的byteArray。byteArray表示为RGB。我正在将其转换为位图。我检查了位图不为空。但当我使用ImageView.setImageBitmap（位图）时，我的Android应用程序崩溃。我已经尝试了很多方法，但我还没有找到解决方案。请帮助我

class Cam : AppCompatActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        Log.d("Cam activity", "onCreate")
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_cam)

        val button_back : Button = findViewById(R.id.button_back)!!
        var textView : TextView = findViewById(R.id.textView)!!
        var imageView: ImageView = findViewById(R.id.Image_update)!!

        Thread {
            Thread.sleep(1000)
            var byteArray = ByteArray(76032)
            Connection.inBytesCam?.read(byteArray)
            var nrOfPixels = byteArray.size / 3 // Three bytes per pixel.
            var pixels = IntArray(nrOfPixels)
            for (i in 0 until nrOfPixels){
                var r = byteArray.get(3*i).toInt()
                var g = byteArray.get(3*i + 1).toInt()
                var b = byteArray.get(3*i + 2).toInt()
                pixels.set(i, Color.rgb(r, g, b))
            }
            var bitmap = Bitmap.createBitmap(pixels, 176, 144, Bitmap.Config.ARGB_8888)
            imageView.setImageBitmap(bitmap)

        }.start()

        button_back.setOnClickListener {
            Thread {
                runOnUiThread {
                    val intent = Intent(this@Cam, ControlActivity::class.java)
                    startActivity(intent)
                }
            }.start()
        }

    }
}

我使用DataInputStream/DataOutputStream将ImageBytes从本地服务器传输到Android上的客户端。我找不到任何解决我的问题的方法
一般来说，我需要在循环中更新图像，就像视频播放器一样。但是我甚至不能更新一个图像：（
