An AdapterView (like ListView, GridView, etc.) is a view bound to an Adapter that determines the view's children. In Espresso, you can match these children views using the onData() method instead of onView() as you would do normally. Instead of matching views, onData() matches the data that is bound to each view item.
This project uses the Gradle build system. You don't need an IDE to build and execute it but Android Studio is recommended.
git clone
../build.gradle

The application will be started on the device/emulator and a series of actions will be performed automatically.
If you are using Android Studio, the Run window will show the test results.
