标签: illegalstateexception

我正在开发一个应用程序，其中我有一个用 ScrollView 包装的布局。在此布局的片段中，我正在使用 Web 服务从服务器获取数据并将其显示在我的布局中。每当 Web 服务中出现错误或没有可用数据时，我都会向用户显示一个带有相应消息的快捷栏。

问题

我遇到了一个很少发生的问题。当有时数据不可用并显示小吃栏时，我的应用程序崩溃并显示消息的非法状态异常

ScrollView can host only one direct child

这是崩溃日志

我正在为 android 中的广播应用程序构建媒体样式通知。这是我的通知代码：

NotificationCompat.Action action = new android.support.v4.app.NotificationCompat.Action.Builder(imgNotificationAction, "playPause", pendingIntent).build();\n    //create new notification\n    NotificationCompat.Builder notificationBuilder = (NotificationCompat.Builder) new NotificationCompat.Builder(this)\n            .setShowWhen(false)\n            .setStyle(new NotificationCompat.MediaStyle()\n                    .setMediaSession(mediaSession.getSessionToken())\n                    .setShowActionsInCompactView(0, 1, 2))\n            .setColor(ContextCompat.getColor(this, R.color.colorPrimary))\n            //.setLargeIcon(largeIcon)\n            .setSmallIcon(android.R.drawable.stat_sys_headset)\n            .setContentText(radioName)\n            .setContentTitle("Igala Radio presents")\n            .setContentInfo("Igala language radio")\n            .setContentIntent(pendingIntent)\n            .addAction(action);\n\n    NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);\n    notificationManager.notify(NOTIFICATION_ID, notificationBuilder.build());\n

我们的 grails 应用程序中出现java.lang.IllegalStateException: getAttribute: Session already invalidated少量错误。

我们尝试检查过滤器中的会话是否无效，如果是则重定向到同一页面，但这不起作用。看起来会话在请求过程中失效了。

处理此错误的正确方法是什么？我们应该在顶层放置一个错误处理程序并返回一些 http 状态吗？

我按照此文档将ComposeView直接包含在片段中而没有 xml 布局膨胀，但它给出了java.lang.IllegalStateException。

请帮我解决这个问题。

Android Studio：2020.3.1 Canary 14

compose_version :'1.0.0-beta01'

这是片段的代码：

class RecipeListFragment : Fragment() {

private lateinit var viewModel: RecipeListViewModel

override fun onCreateView(
    inflater: LayoutInflater, container: ViewGroup?,
    savedInstanceState: Bundle?
): View {
    return ComposeView(requireContext()).apply {
        setContent {
            Column(
                modifier = Modifier
                    .padding(16.dp)
            ) {
                Text(
                    text = "Recipe List",
                    style = MaterialTheme.typography.h3
                )

我想从我的项目中删除一个项目RecyclerView,但我总是收到错误.

java.lang.IllegalStateException:当RecyclerView正在计算布局或滚动时,无法调用此方法

我在用notifyDataSetChanged().我怎么解决这个问题？

    public ArrayList<String> tvdatalist;
    Context c;
    int pos;
    ListAdapters.MyViewHolder myViewHolder;

    public class MyViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {


        public EditText edttxt;

让我们从Javadocs开始:

IllegalStateException异常

表示在非法或不适当的时间调用了方法.换句话说,Java环境或Java应用程序未处于所请求操作的适当状态.

抛出:IllegalArgumentException

抛出以指示方法已被传递非法或不适当的参数.

上述问题是它们非常黑白.考虑一种方法,其中方法正在解析调用者提供的文件.该文件存在,可读,格式正确.但是,文件中的某些内容不符合业务规则.在这种情况下抛出什么是适当的例外 - IllegalStateException或者IllegalArgumentException？

查看提供断言的各种库,例如Guava Preconditions或Spring Assert,似乎没有达成共识.这里和这里有一些很好的讨论,但没有一个能为我上面提到的常见用例提供确凿的答案.

免责声明:据我所知,我没有展示一些代码,但我认为这是一个特殊而实用的问题,需要考虑进行良好的API设计.让我们假装我们回到了堆栈溢出的好日子,当时人们乐于讨论实用问题,而不是贬低任何看起来不像家庭作业的东西.
