实现
1:注册高德地图开发者账号，创建应用、获取高德地图的 appkey
2: jar 包建议直接从 融云 demo 中拷贝。因为某地图厂商的版本兼容做的不好。可能你下载的新版本的 jar. 在老版本的实现代码中就找不到这个接口。或者那个接口变动了
3: 参考 demo 代码 在 RongCloudEvent.java 上实现了 地理位置提供者接口 。 onStartLocation 方法中点击开启 地图的 Activity
@Override
public void onStartLocation(Context context, LocationCallback locationCallback) {
/**
* demo 代码 开发者需替换成自己的代码。
*/
DemoContext.getInstance().setLastLocationCallback(locationCallback);
Intent intent = new Intent(context, AMAPLocationActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(intent);AMAPLocationActivity 为核心逻辑类。高德地图的展示 获取经纬度和定位的逻辑全在此处

将代码拷贝 和 相关资源文件拷贝以后就能实现。下面对代码逻辑做一下介绍
代码整体分两部分 一部分是发送位置逻辑 一部分是从会话界面地理位置消息点击进来逻辑。主要逻辑是 发送位置逻辑
@Override
public void onLocationChanged(AMapLocation aMapLocation) {
if (aMapLocation != null && aMapLocation.getAMapException().getErrorCode() == 0) {如果卡在这个 if 判断没有进来那说明你配置的高德相关的 jar 、key 、storeFile(此处在 gradle 配置) 配置高德环境有问题。此处具体咨询高德地图
另外需要值得注意的一点是获取静态缩略图的问题
private Uri getMapUrl(double x, double y) {
String url = "http://restapi.amap.com/v3/staticmap?location=" + y + "," + x +
"&zoom=17&scale=2&size=150*150&markers=mid,,A:" + y + ","
+ x + "&key=" + "ee95e52bf08006f63fd29bcfbcf21df0";
NLog.e("getMapUrl", url);
return Uri.parse(url);
}最后组拼的 key.在高德官网解释是说需要配置自己的 高德key.这里是个坑，我拿着自己的 key 去浏览器中解析 返回错误码 10009
当时给愁坏了。后来朋友提示随意拿个别人的 key 绑定了 web api 的去使用试试。结果还真行。所以在此处参考博文的小伙伴直接用上面 demo 提供的 key 即可。
点击地理位置消息预览的逻辑 在 RongCloudEvent.java 重写消息点击事件
if (message.getContent() instanceof LocationMessage) {
Intent intent = new Intent(context, AMAPLocationActivity.class);
intent.putExtra("location", message.getContent());
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(intent);
}在 AMAPLocationActivity 截取并且判断这个 intent
if (getIntent().hasExtra("location")) {
isPerview = true;
mMsg = getIntent().getParcelableExtra("location");
tvCurLocation.setVisibility(View.GONE);
returns.setVisibility(View.GONE);
if (model) {
CameraPosition location = new CameraPosition.Builder()
.target(new LatLng(mMsg.getLat(), mMsg.getLng())).zoom(18).bearing(0).tilt(30).build();
show(location);
} else {
aMap.addMarker(new MarkerOptions().anchor(0.5f, 0.5f)
.position(new LatLng(mMsg.getLat(), mMsg.getLng())).title(mMsg.getPoi())
.snippet(mMsg.getLat() + "," + mMsg.getLng()).draggable(false));
}
return;
}最后的 return 不继续执行代码。完成当前位置的预览即结束
