Can't instantiate FloatingActionButton class

I'm following Udacity Google's android basic course data storage. I am not able to instantiate FloatingActionButton class.

FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.myfab)

It says can't resolve symbol 'FloatingActionButton.' If someone could help me to create FloatingActionButton, I would really appreciate it.

Solution

  • did you add the support:design in build.gradle: module app to dependencies.

    compile 'com.android.support:design:27.1.1'

    if using gradle plugin 3.0+

    api 'com.android.support:design:27.1.1'
