Java 带工具栏的RecyclerView

我对材料设计是新手，每次我尝试使用RecyclerView时，都会发现一切都错了

有人知道问题出在哪里吗

并重新构建应用程序

错误：

尝试编辑此文件

尝试编辑此

好的，我在

回收商的
onCreateView
中找到了问题

recyclerView= (RecyclerView) getActivity().findViewById(R.id.recye);

将其更改为：

recyclerView= (RecyclerView) view.findViewById(R.id.recye);

好的，我在
回收器的
onCreateView
中发现了这个问题

recyclerView= (RecyclerView) getActivity().findViewById(R.id.recye);

将其更改为：

recyclerView= (RecyclerView) view.findViewById(R.id.recye);



试试这个：

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <android.support.v7.widget.RecyclerView
        android:id="@+id/recyclerView"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:paddingTop="?attr/actionBarSize"
        android:clipToPadding="false"/>

    <android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"
        android:background="?attr/colorPrimary"/>

</FrameLayout>


及

请在任何问题中使用knw
尝试以下方法：

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <android.support.v7.widget.RecyclerView
        android:id="@+id/recyclerView"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:paddingTop="?attr/actionBarSize"
        android:clipToPadding="false"/>

    <android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"
        android:background="?attr/colorPrimary"/>

</FrameLayout>
