Question

我正在尝试为仪器测试做一个课程。该类位于androidTest文件夹app\src\androidTest\java\...中。但是，AndroidJUnit4和ActivityTestRule无法解决。在import语句中，import android.support.test.runner.AndroidJUnit4单词“runner”为红色。测试课在Kotlin。我尝试删除它并在Java中创建一个，但仍无法导入AdnroidJUnit4。我读了一些类似的问题，但没有找到我的案例的解决方案。这两个是项目和应用程序build.gradle文件：我的gradle文件有什么问题吗？ app build.gradle：

apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-kapt'

android {
    compileSdkVersion rootProject.ext.compileSdkVersion

    defaultConfig {
        applicationId "com.sample.me"

    }

    dependencies {

      }

        }

        task clean(type: Delete) {
            delete rootProject.buildDir
        }

更新最后发现这是因为项目路径中有空格。我删除了空格，现在可以导入类了。

尝试在依赖性中添加这些

androidTestCompile 'com.android.support.test:rules:1.0.2'
androidTestCompile 'com.android.support.test:runner:1.0.2'

无法导入AndroidJUnit4和ActivityTestRule
