Question

在我的build.gradle文件中，我有支持库依赖项：

compile "com.android.support:appcompat-v7:22.2.0"
compile "com.android.support:recyclerview-v7:22.2.0"
compile "com.android.support:design:22.2.0"

我也有espresso测试的依赖项：

androidTestCompile 'com.android.support.test.espresso:espresso-core:2.2'
androidTestCompile 'com.android.support.test.espresso:espresso-intents:2.2'

此时所有内容都运行良好，但当我添加espresso-contrib的依赖项时，我在InflateException上获得RecyclerView

android.view.InflateException: Binary XML file line #33: Error inflating class android.support.v7.widget.RecyclerView

有关为什么会发生这种情况以及如何解决这个问题的想法？

Answer 1

在build.gradle中试试这个：

androidTestCompile ('com.android.support.test.espresso:espresso-contrib:2.2'){
    exclude group: 'com.android.support', module: 'appcompat-v7'
    exclude group: 'com.android.support', module: 'support-v4'
    exclude module: 'recyclerview-v7'
}

Answer 2

我有关于错误膨胀类回收器视图的相同问题，并尝试了多次使用各种代码，最后我通过在项目gradle中添加这些代码解决了这个问题：

 androidTestCompile 'com.android.support.test.espresso:espresso-intents:2.2.1'
androidTestCompile ('com.android.support.test.espresso:espresso-core:2.2.1') {
    exclude module: 'support-annotations'
}
androidTestCompile ('com.android.support.test.espresso:espresso-contrib:2.2.1') {
    exclude module: 'support-annotations'
    exclude module: 'support-v4'
    exclude module: 'recyclerview-v7'
}

其次，您必须确保在最新版本中使用卡片视图和回收者视图：

compile 'com.android.support:cardview-v7:23.1.1'
compile 'com.android.support:recyclerview-v7:23.1.1'

然后，您可以在其活动布局中运行具有回收站视图的测试。它会正常工作，不会再出现错误。

Answer 3

试试这个：

// Testing dependencies
androidTestCompile 'com.android.support.test:runner:0.4.1'
androidTestCompile 'com.android.support.test:rules:0.4.1'
androidTestCompile 'com.android.support.test.espresso:espresso-core:2.2.1'
androidTestCompile 'com.android.support.test.espresso:espresso-intents:2.2.1'
    androidTestCompile('com.android.support.test.espresso:espresso-contrib:2.2.1') {
        exclude group: 'com.android.support', module: 'appcompat'
        exclude group: 'com.android.support', module: 'support-v4'
        exclude module: 'support-annotations'
        exclude module: 'recyclerview-v7'
    }

为什么添加espresso-contrib会导致InflateException？
