How do I maintain the Immersive Mode in Spinner?

Question

I use immersive-sticky mode to hide the navigation bar and action bar:

@TargetApi(19)
private void setImmersiveMode() {
    if (Build.VERSION.SDK_INT >= 1

I know this is super late, but I finally found a solution to this here:

Just call this on your spinner before using it:

import android.widget.PopupWindow
import android.widget.Spinner

fun Spinner.avoidDropdownFocus() {
    try {
        val isAppCompat = this is androidx.appcompat.widget.AppCompatSpinner
        val spinnerClass = if (isAppCompat) androidx.appcompat.widget.AppCompatSpinner::class.java else Spinner::class.java
        val popupWindowClass = if (isAppCompat) androidx.appcompat.widget.ListPopupWindow::class.java else android.widget.ListPopupWindow::class.java

        val listPopup = spinnerClass
                .getDeclaredField("mPopup")
                .apply { isAccessible = true }
                .get(this)
        if (popupWindowClass.isInstance(listPopup)) {
            val popup = popupWindowClass
                    .getDeclaredField("mPopup")
                    .apply { isAccessible = true }
                    .get(listPopup)
            if (popup is PopupWindow) {
                popup.isFocusable = false
            }
        }
    } catch (e: Exception) {
        e.printStackTrace()
    }
}
