Android viewpager实例化Item（）方法'；s错误，无法在碎片中展开布局

错误：

主活动代码为空，布局为：

<?xml version="1.0" encoding="UTF-8"?>

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity">

<fragment
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  android:id="@+id/fragment"
  android:name="com.example.circularview.CarFragment"
  tools:layout="@layout/fragment_car" />
</RelativeLayout>

正如我认为它应该从我的项目布局，在这里

项目布局：
