This generally happens when you are using different versions of SDK and support libraries. Replace the versions of these

compile 'com.android.support:cardview-v7:26.0.0-alpha1'
compile 'com.android.support:design:26.0.0-alpha1'

to

compile 'com.android.support:cardview-v7:27.1.0'
compile 'com.android.support:design:27.1.0'

and it should work.
