UIFont有获取常规font(systemFontOfSize)或粗体字体(boldSystemFontOfSize)的方法,但如何通过故事板获得"瘦系统字体"？

将"system-thin"传递给UIFontContructor不起作用,此构造函数仅适用于非系统字体.

我收到错误：

无法使用前端 dockerfile.v0 解决：无法创建 LLB 定义：清单中的平台不匹配

构建以下 Dockerfile 时：

FROM mcr.microsoft.com/dotnet/framework/aspnet:4.8
COPY . /inetpub/wwwroot

将库更新com.google.firebase:firebase-core:16.0.6到版本16.0.7 后出现此错误 .

Could not get resource 'https://dl.google.com/dl/android/maven2/com/google/firebase/firebase-measurement-connector-impl/17.0.5/firebase-measurement-connector-impl-17.0.5-javadoc.jar'.

无论如何它都会编译.谁知道怎么解决这个问题？

这里的堆栈:

更新测试项目后NuGet我收到此错误:

类型'TestClassAttribute'存在于'Microsoft.VisualStudio.QualityTools.UnitTestFramework,Version = 10.0.0.0,Culture = neutral,PublicKeyToken = b03f5f7f11d50a3a'和'Microsoft.VisualStudio.TestPlatform.TestFramework,Version = 14.0.0.0,Culture = neutral ,PublicKeyToken = b03f5f7f11d50a3a'

我应该保留哪一个？

我只是在 Windows 2019 服务器上安装 docker 来运行 linux 容器。

我遵循本指南“在 Windows Server 2019 上运行 Linux 容器”一章。当我尝试运行 bash shell 时，出现以下错误：

docker.exe：注册失败层：未能启动服务工具VM（applydiffe53547ea1d150a4e4afba05378a3a45be5ea769d52fddf03ff25dbd09e43d20d）：集装箱e53547ea1d150a4e4afba05378a3a45be5ea769d52fddf03ff25dbd09e43d20d_svm CreateContainer过程中遇到错误：未能在Windows系统调用：因为没有安装所需功能的虚拟机无法启动。

有谁知道缺少什么功能？

更新： 看来问题与程序中的第一个错误有关。运行时：

Get-VM WinContainerHost | Set-VMProcessor -ExposeVirtualizationExtensions $true

它抛出错误：

Get-VM : Hyper-V was unable to find a virtual machine with name "ContainerHost". 

我不相信这是脚本中的指南，因为没有任何命令可以创建这个 WinContainerHost 虚拟机。

解决更令人困惑，有 2 种类型的容器，hyper-v 和服务器容器，如本 指南中所述。我不确定要遵循什么路径。我很失落。

我在 Android 5.0 (API 21) 上进行了以下错误测试。在其他操作系统版本上测试运行良好。

java.lang.RuntimeException：无法启动活动 ComponentInfo{...ui.activities.navigationActivity.fragments.legalFragment.LegalDetailActivity}：android.view.InflateException：二进制 XML 文件第 24 行：错误膨胀类 android.webkit.WebView

找不到关于 xml 布局的任何特别之处，在第 24 行：

<WebView
    android:id="@+id/nav_fg_legal_detail_web"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
  />

编码：

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)

    setTheme(R.style.AppTheme_NoActionBar)
    setContentView(R.layout.legal_detail_activity) // crash here. Nothing done to web view yet.

我正在使用库“androidx.appcompat:appcompat:1.1.0”。

我的单元测试从 Visual Studio 2019 16.3.5 的 TestExplorer 中消失

我有一个多语言站点，需要根据每个页面的语言设置 HTML lang 属性。

我尝试在上下文中传递值，但在页面更改时不更新。

这是当前的代码：

import Document, { Html, Head, Main, NextScript } from 'next/document'
import GlobalContext , {eLanguage }from '../components/GlobalContext' //my global context 

export default class MyDocument extends Document {

static async getInitialProps(ctx) {

  const initialProps = await Document.getInitialProps(ctx)
  return { ...initialProps }
}
static contextType = GlobalContext;
render() {

  console.debug('Started')
  console.debug('language:'+ this.context.language) 

  return (
    <Html lang={eLanguage[this.context.language]}> //if the first page loaded as lang 'en' it sets 'en' and apply to all other pages.
      <Head>
      </Head>
      <body>       
        <Main …

我收到了错误

错误:参数"data"不是有效的Document.输入不是普通的JavaScript对象.

使用firebase admin SDK更新文档时.这里是Typescript代码.

var myDoc = new MyDoc();
myDoc.Public.Name = "Jonh Doe" //setup up content

admin.firestore()
     .collection('MyDocs')
     .doc("Id1")
     .set(myDoc);

将适配器代码转换为Kotlin之后，我得到了此错误：

java.lang.IllegalArgumentException: Parameter specified as non-null is null: method kotlin.jvm.internal.Intrinsics.checkParameterIsNotNull, parameter convertView
    at ...MyAdapter.getView(Unknown Source:35)
    at android.widget.HeaderViewListAdapter.getView(HeaderViewListAdapter.java:220)
    at android.widget.AbsListView.obtainView(AbsListView.java:2366)

扩大行时会引发错误：

class LegalAdapter internal constructor(private val activity: Activity, private val list: ArrayList<Item>) : BaseAdapter() {

    override fun getView(position: Int, convertView: View, parent: ViewGroup): View {

    val layoutInflater = activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE) as LayoutInflater

    @SuppressLint("ViewHolder")
    val row = layoutInflater.inflate(R.layout.legal_list_item, parent, false) //exception is throw here

显然，某些不应该为null的参数为null，然后kotlin对其进行检查。问题是我什至无法调试新的kotlin代码。
