UPDATED ::

1. Best Practice to do that is

   and add library for cardview

   dependencies {
      ...
      compile 'com.android.support:cardview-v7:21.0.+'
    }
   

2. On Pre-Lollipop you can use this drawable

   android:background="@android:drawable/dialog_holo_light_frame"

   it will give you the look of elevation

3. you can create your own like this
