Android 打开通知时如何在地图上显示lat lng点？

我正在开发一个应用程序，我想在打开通知时显示地图，我成功地收到了通知，但当我打开通知时，并没有用那个lat long值打开地图

你不能把这叫做

 Intent noticeIntent = getIntent();

在onCreate（）方法之前

您应该将其放在onCreate（）方法中

把这个从

  String message = noticeIntent.getExtras().getString("message");

到

---

您应该在

ShowMapActivity

中创建

noticecontent

内部

onCreate（..）

Intent noticeIntent = getIntent();
String message = noticeIntent.getStringExtras("message");

---

您的活动是否正在打开？您的活动是否在

manifest.xml

中注册？否不选择我的活动是否在manifesti中注册在logcat中添加了exeption请查看Y以了解延迟响应及其即将到来的映射，但我想直接转到我的位置，而不从映射中缩小，。如何可能请告诉我您可以使用CameraUpdate CameraUpdate=CameraUpdateFactory.newLatLngZoom（latLng，10）；map.animateCamera（cameraUpdate）；是的，它只工作了一次，从第二次通知开始，没有直接显示它现在来了，但标记只是com和过去了我的logcat错误时间倒退：上一次1392207807105446（ioctl）对下一次139220780698404（ioctl），tid=19417发生了什么？标记来了，但在几秒钟后又消失了，地图上没有标记

 @Override
 protected void onCreate(Bundle savedInstanceState) {
     super.onCreate(savedInstanceState);
     setContentView(R.layout.activity_show_map);
     Intent noticeIntent = getIntent();  
     // ...
 }

  String message = noticeIntent.getExtras().getString("message");

 String message = noticeIntent.getStringExtras("message");

Intent noticeIntent = getIntent();
String message = noticeIntent.getStringExtras("message");
