Question

如上所述，我试图在我的应用程序中实现googlemaps，并在开始生成地图片段xml时不断收到“错误膨胀类片段”错误。这是片段所在的xml标签：

            <android.support.constraint.ConstraintLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <fragment
        android:id="@+id/activity_main_map_display"
        android:name="com.google.android.gms.maps.SupportMapFragment"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        tools:context=".MainActivity" />

    <EditText
        android:id="@+id/activity_main_text_edit"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:background="@color/colorWhite"
        android:inputType="text"
        android:text="@string/activity_main_search_button"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent" />
</android.support.constraint.ConstraintLayout>

这是我收到的错误消息（第21行是fragment标签的开头）：

Answer 1

作为一个片段，可以使用documentation下面的XML将该组件添加到活动的布局文件中：

propget

替换此行：

android：name =“ com.google.android.gms.maps.SupportMapFragment”

并确保您添加了依赖项：

<fragment
    class="com.google.android.gms.maps.SupportMapFragment"
    android:layout_width="match_parent"
    android:layout_height="match_parent"/>

Answer 2

解决方案：

 android:class"com.google.android.gms.maps.SupportMapFragment"
 Change it like this :

 android:name="com.google.android.gms.maps.SupportMapFragment"
