首先抛出异常日志，在

先说结论：因为session安装监听是在点击事件里面，所以会保留旧的对象数据

直接上代码，原有的逻辑是点击时执行session安装，并注册监听回调

  private fun installApk(position: Int) {val packageInstaller = packageManager.packageInstallerval params =PackageInstaller.SessionParams(PackageInstaller.SessionParams.MODE_FULL_INSTALL)params.setSize(File(itemList[position].path).length())val sessionId = packageInstaller.createSession(params)val session = packageInstaller.openSession(sessionId)// 注册安装进度监听器val sessionCallback = object : PackageInstaller.SessionCallback() {override fun onCreated(sessionId: Int) {// 安装会话创建成功Log.i("InstallProgress", "Session created: $sessionId")}override fun onProgressChanged(sessionId: Int, progress: Float) {// 安装进度更新itemList[mPosition].installed = 1itemList[mPosition].progress = progress * 100adapter.notifyItemChanged(mPosition)Log.d("install","onProgressChanged: $mPosition ${itemList[mPosition].installed} $progress")}override fun onFinished(sessionId: Int, success: Boolean) {if (success) {// 安装成功itemList[mPosition].installed = 2} else {// 安装失败itemList[mPosition].installed = 3}adapter.notifyItemChanged(mPosition)Log.d("install","onProgressChanged: $mPosition ${itemList[mPosition].installed} $success")}override fun onActiveChanged(sessionId: Int, active: Boolean) {// 安装会话激活状态发生变化}override fun onBadgingChanged(sessionId: Int) {// 应用图标发生变化}}// 注册监听器packageManager.packageInstaller.registerSessionCallback(sessionCallback)try {val inputStream = FileInputStream(itemList[position].path)val outputStream = session.openWrite("base.apk", 0, -1) // -1 表示自动计算大小inputStream.copyTo(outputStream)session.fsync(outputStream)inputStream.close()outputStream.close()val intent = Intent(context, PackageInstallReceiver::class.java).apply {action = itemList[position].pkgputExtra(PackageInstaller.EXTRA_PACKAGE_NAME, itemList[position].pkg)}val pendingIntent = PendingIntent.getBroadcast(context,0,intent,PendingIntent.FLAG_UPDATE_CURRENT)session.commit(pendingIntent.intentSender)} catch (e: IOException) {session.abandon()e.printStackTrace()}}

修改后，将监听注册到onCreate中，并

    override fun onCreate(savedInstanceState: Bundle?) {super.onCreate(savedInstanceState)// 注册监听器packageManager.packageInstaller.registerSessionCallback(sessionCallback)}// 注册安装进度监听器private val sessionCallback = object : PackageInstaller.SessionCallback() {override fun onCreated(sessionId: Int) {// 安装会话创建成功Log.i("InstallProgress", "Session created: $sessionId")}override fun onProgressChanged(sessionId: Int, progress: Float) {// 安装进度更新itemList[mPosition].installed = 1itemList[mPosition].progress = progress * 100adapter.notifyItemChanged(mPosition)Log.d("installApk", "onProgressChanged: $mPosition ${itemList[mPosition].installed} $progress")}override fun onFinished(sessionId: Int, success: Boolean) {if (success) {// 安装成功itemList[mPosition].installed = 2} else {// 安装失败itemList[mPosition].installed = 3}adapter.notifyItemChanged(mPosition)Log.d("installApk", "onProgressChanged: $mPosition ${itemList[mPosition].installed} $success")}override fun onActiveChanged(sessionId: Int, active: Boolean) {// 安装会话激活状态发生变化}override fun onBadgingChanged(sessionId: Int) {// 应用图标发生变化}}private fun installApk(position: Int) {val packageInstaller = packageManager.packageInstallerval params =PackageInstaller.SessionParams(PackageInstaller.SessionParams.MODE_FULL_INSTALL)params.setSize(File(itemList[position].path).length())val sessionId = packageInstaller.createSession(params)val session = packageInstaller.openSession(sessionId)try {val inputStream = FileInputStream(itemList[position].path)val outputStream = session.openWrite("base.apk", 0, -1) // -1 表示自动计算大小inputStream.copyTo(outputStream)session.fsync(outputStream)inputStream.close()outputStream.close()val intent = Intent(context, PackageInstallReceiver::class.java).apply {action = itemList[position].pkgputExtra(PackageInstaller.EXTRA_PACKAGE_NAME, itemList[position].pkg)}val pendingIntent = PendingIntent.getBroadcast(context,0,intent,PendingIntent.FLAG_UPDATE_CURRENT)session.commit(pendingIntent.intentSender)} catch (e: IOException) {session.abandon()e.printStackTrace()}}
