android-layout - 无法在相对布局中添加片段标签

Question

我想在 Activity 的 RelativeLayout 中添加一个标签。但是我遇到了渲染错误。

有什么解决办法吗？

编辑:添加崩溃的堆栈跟踪

根据@Nazariy Moshenskiy 的建议，我需要添加 android:name属性为 <fragment>标签。

这是我的布局的样子(以防将来有人遇到同样的问题)。

<?xml version="1.0" encoding="utf-8"?>
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:map="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/map"
    android:name="com.google.android.gms.maps.SupportMapFragment"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    map:cameraZoom="2"

    tools:context=".MapsActivityNew" />
