我正在尝试在我的应用程序中设置 Google 登录。我在 XML 文件中遇到错误

我的 XML

<TextView
    android:id="@+id/hello"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="@string/hello_world" />

<com.google.android.gms.common.SignInButton
    android:id="@+id/sign_in_button"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentRight="true"
    android:layout_below="@+id/hello"
    android:layout_toRightOf="@+id/sign_revoke" />

<Button
    android:id="@+id/sign_revoke"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_below="@+id/sign_in_button" 
    android:text="Revoke Access"/>

错误
