当我点击窗口中的'ok'添加这些时，它显示添加依赖项失败，并且我的导航XML编辑器不可见

build gradle project:

// Top-level build file where you can add configuration options common 

到所有子项目/模块。buildscript {

ext {
version_navigation = "2.3.0"
kotlin_version = "1.4.32"
}
repositories {
google()
jcenter()
}
dependencies {
classpath "com.android.tools.build:gradle:4.1.0"
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"

// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}}

Answer 1

你要做的是:

在build.gradle(项目版本)中，找到ext { }的位置并将其放入:

navigationVersion = "2.3.0"

然后，在build.gradle(模块)中，在dependencies { }中，您必须放置这两个依赖项:

implementation "androidx.navigation:navigation-fragment-ktx:$navigationVersion"
implementation "androidx.navigation:navigation-ui-ktx:$navigationVersion"

最后，同步项目与gradle文件和这是为了确保一切都好。

你可以把navigationVersion改成你在项目gradle中使用的版本。

如果遇到一些额外的问题，请遵循此代码库。
