nosuchmethoderror：在类landroid/util/sparsearray中没有包含(I)Z的虚拟方法；

Question

1.每当我在我的应用中刷下一张图片时，应用崩溃了，我不知道出了什么问题

noSuchMethodError：类landroid/util/sparsearray中没有包含(I)Z的虚拟方法；或其超类（“android.util.sparsearray”的声明出现在/system/framework/framework.jar！classes2.dex中）

class PostViewFragment : DialogFragment() {
private var player: SimpleExoPlayer? = null
private lateinit var mediaDataSourceFactory: DataSource.Factory
//var post: FeedNodeModel? = null

private var post: FeedNodeModel? = null

                        registeredFragments[currentPos]?.onPause()

                    currentPos = position
                    view.txt_pager_count.text = "${currentPos+1}/${post?.feedNodeModel?.size}"

                    if (registeredFragments.contains(position)) {
                        registeredFragments[position]?.loadVideo()

            view.viewpager.visibility = View.VISIBLE
            view.img_post.visibility = View.GONE
            view.playerView.visibility = View.GONE
        }
    }

此行应用程序崩溃

 if (registeredFragments.contains(position)) {
                        registeredFragments[position]?.loadVideo()
                    }

Answer 1

使用containskey

/** Returns true if the collection contains [key]. */
inline fun <T> SparseArray<T>.containsKey(key: Int) = indexOfKey(key) >= 0
