尽管我不太确定,但由于com.android.support:appcompat-v7:28.0.0-rc01,我的android studio似乎无法正确渲染
这是显示的错误消息
所有com.android.support库必须使用完全相同的版本规范(混合版本可能导致运行时崩溃)。找到版本28.0.0-rc01,26.1.0。示例包括com.android.support:animated-vector-drawable:28.0.0-rc01和com.android.support:support-media-compat:26.1.0 less ...(Ctrl + F1) 有一些库,工具或库的组合不兼容或可能导致错误。一种不兼容的情况是使用不是最新版本(或特别是低于targetSdkVersion的版本)的Android支持库版本进行编译。
这是我的gradle build(项目)
// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
repositories {
google()
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.1.4'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
classpath 'com.google.gms:google-services:4.0.1'
}
}
allprojects {
repositories {
google()
jcenter()
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}
这是我的gradle build(模块)
//noinspection GradleCompatible

TL; DR
之所以发生这种情况,是因为在支持库28.0.0-rc01中存在一个与发布Appcompat ActionBar相关的错误,并带有未知错误。
build.gradel
文件compileSdkVersion 27
27 而不是 28 targetSdkVersion 27
27 而不是 28 implementation 'com.android.support:appcompat-v7:27.1.1'
27.1.1 而不是 28.0.0-rc01 P.S。:-这并不意味着降级是一个不错的选择或答案,但现在是这样!

尝试一下 在您的版本中:
buildscript {
repositories {
google()
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.0.1'
// NOTE: Do not place your application
dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
maven {
url "https://maven.google.com"
}
maven { url 'https://jitpack.io' }
google()
jcenter()
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}
