为什么添加espresso-contrib会导致InflateException? [英] Why would adding espresso-contrib cause an InflateException?

问题描述

在我的build.gradle文件中，我具有支持库依赖项:

In my build.gradle file I have the support library dependencies:

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"

我也有意式浓缩咖啡测试的依赖项:

I also have dependencies for espresso tests:

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

此时一切正常，但是当我添加espresso-contrib的依赖项时，我在RecyclerView

Everything runs fine at this point, but when I add the dependency for espresso-contrib I get an InflateException on my RecyclerView

关于为什么会发生这种情况以及如何解决它的任何想法?

Any idea on why this might be happening and how I can fix it?

推荐答案

在build.gradle中尝试:

Try this in your build.gradle:

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'
}
