              android:layout_width="match_parent"
              android:layout_height="wrap_content"
              app:contentPadding="10dp"
              app:cardElevation="2dp"
              app:cardBackgroundColor="@android:color/white"&gt;
  
              &lt;LinearLayout
                  android:layout_width="match_parent"
                  android:layout_height="wrap_content"
                  android:orientation="vertical"&gt;
  
                  &lt;com.google.android.gms.common.SignInButton
                      android:id="@+id/google_login_button"
                      android:layout_width="@dimen/sign_in_btn_width"
                      android:layout_height="wrap_content"
                      android:layout_gravity="center_horizontal" /&gt;
