Java 为什么不是'；图中没有显示地图碎片吗？

所以我试着做一个包含谷歌地图片段的简单应用程序。我从安卓工作室的预设开始。从新开始，显示工具栏，但不显示地图片段。下面，您将看到我的代码和堆栈跟踪：

这一点反复出现。我在Android 6.0.1上使用OnePlus 1，并显示了API 23。应用程序运行，但不显示地图片段

对于布局：

如果您正在使用自定义的工具栏，最好将样式更改为 无操作栏

 <style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">

对于那个地图片段

 android:layout_below="@+id/toolbar"
 android:layout_width="match_parent"
 android:layout_height="match_parent"

这将简单地将工具栏作为地图片段放置在顶部和下方

现在，对于未显示的地图：

你有没有在你的应用程序中加入谷歌播放服务的依赖项

还要将其添加到您权限上方的清单文件中

 <permission
        android:name="your_package_name.permission.MAPS_RECEIVE"
        android:protectionLevel="signature"/>

抱歉，我无法发表评论，所以发布了一个答案

希望能有帮助

这是因为地图不应该是整个屏幕。工具栏也应该有一个位置。然后使用线性布局。。。没有理由硬编码一个元素的大小，我改变了它，但错误保持不变same@cricket_007我删除了布局图，它成功了！非常感谢！
