我有一个应用程序。我有一个位置信息到谷歌地图。我想从我使用谷歌地图的地方创建一个路径。
String url = "yandexmaps://maps.yandex.ru/?pt=" + routePlan.getLocationLat() + "" + routePlan.getLocationLong() + "&z=12&l=map";
Intent intentYandex = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
intentYandex.setPackage("ru.yandex.yandexmaps");
String uriGoogle = "geo:" +routePlan.getLocationLat()+"," + routePlan.getLocationLong();
Intent intentGoogle = new Intent(Intent.ACTION_VIEW, Uri.parse(uriGoogle));
intentGoogle.setPackage("com.google.android.apps.maps");
String title = "Select";
Intent chooserIntent = Intent.createChooser(intentGoogle, title);
Intent[] arr = new Intent[1];
arr[0] = intentYandex;
chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, arr);
startActivity(chooserIntent);
谷歌有这方面的服务。您可以使用Google Maps sdk和Google的Directions API
只需向谷歌的方向 api 发送 http 请求即可
https://maps.googleapis.com/maps/api/directions/outputFormat?parameters
它将返回如下所示的 json 响应：
