Android-PickerView 主要是个级联选择器，很好用的插件：
GitHub下载地址
1.无法下载导入插件Android-PickerView
在项目根目录settings.gradle中更换仓库（注意，一些教程里边的url没有使用https协议，可能会导致不成功，所以要使用https）：
pluginManagement {
repositories {
/* gradlePluginPortal()
google()
mavenCentral()*/
maven { url 'https://maven.aliyun.com/nexus/content/repositories/google' }
maven { url 'https://maven.aliyun.com/nexus/content/repositories/jcenter'}
}
}
dependencyResolutionManagement {
repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
repositories {
/*
google()
mavenCentral()*/
maven { url 'https://maven.aliyun.com/nexus/content/repositories/google' }
maven { url 'https://maven.aliyun.com/nexus/content/repositories/jcenter'}
}
}
然后sync一下。
2.gradle配置差异，配置属性问题，其实报错的地方就可以发现了问题所在，按要求改一下咯：
android.useAndroidX=true
android.enableJetifier=true
更改后的gradle.properties
# Project-wide Gradle settings.
# IDE (e.g. Android Studio) users:
# Gradle settings configured through the IDE *will override*
# any settings specified in this file.
# For more details on how to configure your build environment visit
# http://www.gradle.org/docs/current/userguide/build_environment.html
# Specifies the JVM arguments used for the daemon process.
# The setting is particularly useful for tweaking memory settings.
org.gradle.jvmargs=-Xmx2048m -Dfile.encoding=UTF-8
# When configured, Gradle will run in incubating parallel mode.
# This option should only be used with decoupled projects. More details, visit
# http://www.gradle.org/docs/current/userguide/multi_project_builds.html#sec:decoupled_projects
# org.gradle.parallel=true
# AndroidX package structure to make it clearer which packages are bundled with the
# Android operating system, and which are packaged with your app"s APK
# https://developer.android.com/topic/libraries/support-library/androidx-rn
android.useAndroidX=true
# Enables namespacing of each library's R class so that its R class includes only the
# resources declared in the library itself and none from the library's dependencies,
# thereby reducing the size of the R class for that library
android.nonTransitiveRClass=true
android.overridePathCheck=false
android.enableJetifier=true
3.Android-PickerView 使用的SDK版本问题，可能导致无法使用该插件，在SDK Manger中下载吧：
tools->
SDK Manager->
就这样下载吧，32、28、26、27这些老版本都下载吧，按理说在github中可以找到开发文档的，我没看到，我这样说可能也不正确，但我的开发环境试了倒可以，斟酌损益咯。
然后可能会提醒你去设置android.overridePathCheck=false，看情况而定吧
4.有时候没错了但是调试不成：
Edit一下。
5.重中之重，不要随便改SDK位置或者更改虚拟机位置（ini配置文件等）由于你的虚拟机打不开那个啥has terminal的原因，极大建议是删掉虚拟机重装，大概率恢复如初！
暂时能够总结这么些经验了，遇到问题及时分享出来吧，害
