“需要修复导航栏链接的帮助 - 单击“隐私”会重定向到不正确的 URL”
这是我的导航栏的当前代码: 事实生成器 这是我的导航栏的当前代码: <nav> <a href="somerandomthings.xyz"> Fact Generator</a> <a href="somerandomthings.xyz/privacy">Privacy</a> <a href="#">Contact</a> </nav> 这是我的网站:https://somerandomthings.xyz/ 当我访问我的网站并单击“隐私”时,我会转到 https://somerandomthings.xyz/somerandomthings.xyz/privacy 有任何帮助吗,所以它会转到 https://somerandomthings.xyz/privacy ? 您可以使用绝对路径或为“隐私”链接指定根相对路径。 这是更正后的代码: <nav> <a href="https://somerandomthings.xyz">Fact Generator</a> <a href="https://somerandomthings.xyz/privacy">Privacy</a> <a href="#">Contact</a> </nav> 或者,如果您想使用根相对路径: <nav> <a href="/">Fact Generator</a> <a href="/privacy">Privacy</a> <a href="#">Contact</a> </nav> 这样,当您点击“隐私”链接时,它会将您带到正确的 URL:https://somerandomthings.xyz/privacy。
将android studio更新到hedgehog版本后manifest文件出现错误
我正在开发一个运行良好的 Android 应用程序,但当我将 Android Studio 更新到最新版本(即 Hedgehog 2023)时,我开始在清单文件中收到一堆错误。 明显...
Chrome 扩展:在网页中的任何其他 JS 之前运行可访问窗口的自定义 JS
我正在编写Chrome扩展(manifest v3),主要目的是覆盖一些Window本机函数并在任何其他网页脚本可以访问它们之前替换它们。 我有 contentscript.js
活动深层链接 - IllegalArgumentException:缺少必需的参数并且没有 android:defaultValue
在我的应用程序中,我有以下结构: 在我的应用程序中,我具有以下结构: <!-- AndroidManifest.xml --> <?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android"> <application> <activity android:name=".DeepLinkActivity" android:exported="true" android:launchMode="singleInstancePerTask"> <intent-filter> <action android:name="android.intent.action.VIEW" /> <category android:name="android.intent.category.DEFAULT" /> <category android:name="android.intent.category.BROWSABLE" /> <data android:host="myhost" android:path="/mypath" android:scheme="myscheme" /> </intent-filter> </activity> </application> </manifest> <!-- activity_deep_link.xml --> <?xml version="1.0" encoding="utf-8"?> <FrameLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent"> <androidx.fragment.app.FragmentContainerView android:id="@+id/navHostFragment" android:name="androidx.navigation.fragment.NavHostFragment" android:layout_width="match_parent" android:layout_height="match_parent" app:defaultNavHost="true" tools:navGraph="@navigation/my_nav_graph" /> </FrameLayout> // DeepLinkActivity.kt class DeepLinkActivity : AppCompatActivity() { private lateinit var binding: ActivityDeepLinkBinding override fun onCreate(savedInstanceState: Bundle?) { super.onCreate(savedInstanceState) binding = ActivityDeepLinkBinding.inflate(layoutInflater) setContentView(binding.root) setUpNavigationGraph() } private fun setUpNavigationGraph() { val navHostFragment = supportFragmentManager .findFragmentById(binding.navHostFragment.id) as NavHostFragment val navController = navHostFragment.navController val navGraph = navController.navInflater .inflate(R.navigation.my_nav_graph) .apply { this.setStartDestination(R.id.notTheStartDestinationFragment) } val startDestinationArgs = bundleOf( "someRequiredArgumentHere" to false ) navController.setGraph(navGraph, startDestinationArgs) } } 当我通过 ADB (adb shell am start -d myscheme://myhost/mypath) 通过深度链接打开该活动时,该活动正常启动。 但是当我通过 Chrome 应用程序启动它时,应用程序崩溃了: 原因:java.lang.IllegalArgumentException:缺少必需参数“someRequiredArgumentHere”并且没有 android:defaultValue 观察:我正在使用 Safe Args 插件。 我做错了什么以及为什么行为不同? 我刚刚发现为什么在通过浏览器导航时会忽略 startDestinationArgs。 如果我们检查NavController#setGraph(NavGraph, Bundle?)的内部代码,如果没有发生深层链接,NavController#onGraphCreated(Bundle?)只会使用startDestinationArgs。 作为一种解决方法,在设置导航图之前,我只需清除活动的意图(但这可能不是解决该问题的最佳方法)
