How can I fix "Expected resource of type id" error?

Question

I have an error in android studio 4.1.1 I want make image"student_bg" draggable so I added this code and it didn't worked.

this is my tutorial.xml

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:gravity="bottom"
    android:orientation="horizontal">

    <ImageView
        android:id="@+id/character"
        android:layout_width="35dp"
        android:layout_height="100dp"
        android:clickable="true"
        app:srcCompat="@drawable/student_bg" />
</LinearLayout>

and this is my tutorial.kt

var moveX = 0f
var moveY = 0f

class tutorial : AppCompatActivity(), SensorEventListener {

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    getWindow().setFlags(
        WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN)
    setContentView(R.layout.tutorial)

    val st = findViewById<ImageView>(R.drawable.student_bg)

    st.setOnTouchListener { v, event ->
        when(event.action) {
            MotionEvent.ACTION_DOWN -> {
                moveX = v.x - event.rawX
                moveY = v.y - event.rawY
            }
            MotionEvent.ACTION_MOVE -> {
                v.animate()
                        .x(event.rawX + moveX)
                        .y(event.rawY + moveY)
                        .setDuration(0)
                        .start()
            }
        }
        true
    }
}
}

I found create ids.xml will help this issue, but it didn't worked. I made ids.xml

This is my .xml file: tutorial.xml

And this is my .kt file: turotial.kt

Did I missed something? Why it didn't work?

在tutorials.kt中，用“R.id.character”代替“R.drawable.student_bg”，因为findViewById需要一个id，但是你传递了一个drawable并删除了ids.xml
