android测试-我在哪里可以找到ActivityTestRule的源代码

Question

我在哪里可以找到ActivityTestRule的源代码?

Answer 1

你可以在https://android.googlesource.com/platform/frameworks/testing/+/android-support-test/规定/src/main/java/android/支持/测试/规则/ActivityTestRule.java

在AOSP的platform/frameworks/testing项目中，你必须使用android-support-test分支而不是master。

Answer 2

您可以在代码中添加ActivityTestRule，导入库并按CTRL+左键反编译

如果你不能导入这个类，你需要将它添加到build.gradle的dependencies

androidTestCompile 'com.android.support.test:rules:0.3'

编辑:

反编译的结果:
