由于appcompat

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
apply plugin: 'com.android.application'

android {
    compileSdkVersion 28
    defaultConfig {
        applicationId "com.example.jbdelosreyes.finalmvp"
        minSdkVersion 19
        targetSdkVersion 28
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

    implementation 'com.android.support:appcompat-v7:28.0.0-rc01'

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。

在Android团队修复该错误之前如何使用设计视图?

  1. 转到应用--build.gradel文件
  2. compileSdkVersion 27 27 而不是 28
  3. targetSdkVersion 27 27 而不是 28
  4. 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
       }

在Gradle.Build中:

   apply plugin: 'com.android.application'

   android {
   compileSdkVersion 25
   buildToolsVersion "26.0.2"

    defaultConfig {
    applicationId "com.example.naser.arabic"
    minSdkVersion 15
    targetSdkVersion 25
    versionCode 1
    versionName "1.0"
    testInstrumentationRunner 
    "android.support.test.runner.AndroidJUnitRunner"
     }
     buildTypes {
     release {
        minifyEnabled true
        proguardFiles 
        getDefaultProguardFile('proguard- 
        android.txt'), 'proguard-rules.pro'
        }
        }
        sourceSets { main { assets.srcDirs = 
        ['src/main/assets', 'src/main/assets/'] } }
        compileOptions {
        targetCompatibility 1.8
         sourceCompatibility 1.8
       }
       }

      dependencies {
      compile fileTree(include: ['*.jar'], dir: 
      'libs')

           androidTestCompile('
            com.android.support.test.espresso:es 
           presso-core:2.2.2', {
              exclude group: 'com.android.support', 
        module: 
      'support-annotations'
         })
        compile 'com.android.support:appcompat- 
        v7:25.3.1'
        compile files('libs/universal-image-loader- 
        1.9.3.jar')
        compile 
         'com.android.support.constraint:constraint- 
        layout:1.0.0-alpha7'
        compile 'com.android.support:design:25.3.1'
         compile 'com.android.support:support- 
        v4:25.3.1'}
