android - 如何将谷歌地图活动与导航抽屉联系起来？
问题描述
我对android有点陌生，我正在使用显示我当前位置的谷歌地图活动，它工作正常。但是，当我将它包含在导航抽屉布局中时，地图只会出现并且不显示任何内容。我进行了很多研究，例如将地图用作片段，当我单击左侧菜单上的任何元素时会出现该片段，但没有得到任何解决方案！任何帮助，将不胜感激。
这是代码。

The API key for Google Maps-based APIs is defined as a string resource.

Note that the API key is linked to the encryption key used to sign the APK.
You need a different API key for each encryption key, including the release key that is used to
sign the APK for publishing.
You can define the keys for the debug and release targets in src/debug/ and src/release/.

谢谢！。
解决方案
独奏是打开一个新的 navigationDrawarActivity 并将继承从 appCompatActivity 更改为 FragmentActivity，现在您可以添加您的暗示 onMapreadyCallBack 和所有地图暗示以及留下 navigationDrawarActivity 代码和暗示的 mapActivity 代码。你将准备好随心所欲地操纵两者。
我在完成最终项目时遇到了同样的问题，我做了很多研究，但没有发现任何有用的东西，我自己解决了这个问题。
