地图未渲染。仅显示网格线
Posted
技术标签:
【中文标题】地图未渲染。仅显示网格线【英文标题】：Map not rendering. Only Grid lines are shown 【发布时间】：2018-03-26 22:16:16 【问题描述】：我正在使用百度地图（SDK 版本：4.5.2），但地图没有显示。相反，只显示网格线。
代码：
public class MainApp extends MultiDexApplication
@Override
public void onCreate()
super.onCreate();
SDKInitializer.initialize(this);
BaiduMapActivity 类：（此代码在 Kotlin 中。如果您需要此代码的 Java 等效项，请在下方留言。）
class BaiduMapActivity : BaseActivity()
override fun onCreate(savedInstanceState: Bundle?)
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_baidu_map)
override fun onResume()
super.onResume()
bmapView.onResume()

库的结构：
结果如下。应用程序运行良好，但仅显示网格线且地图不可见。
可能的原因是什么？
【问题讨论】：
您能否检查日志并将您可能在那里找到的相关错误添加到您的问题中 @petey 我已经添加了日志。 【参考方案1】：几个选项可能是原因：
Manifest 中没有添加 Api Key API Key 绑定到错误的 SHA1，或者错误的包名 使用模拟器。根据我的测试，从来没有在模拟器上运行过，但在真实设备上运行良好（我打赌这个，因为我在你的日志中没有看到与百度的通信错误）。【讨论】：
【参考方案2】：尝试使用china ***，然后查看地图是否加载
【讨论】：
以上是关于地图未渲染。仅显示网格线的主要内容，如果未能解决你的问题，请参考以下文章
