如何在 Google Maps Android API v2 中沿着我的路线前往加油站

Question

我有一个在起点和终点之间绘制路线的应用程序。 我需要在这条路线上标记加油站。 我已经阅读了谷歌地方 API。 你能告诉我在这种情况下如何使用 Places API 吗？

Answer 1

第一个你需要谷歌地图 api 密钥..你可以从谷歌获得一个..查看 this link。 现在，当您拥有 api 密钥时...您可以使用它来获取所需的位置 this link https://maps.googleapis.com/maps/api/place/nearbysearch/json?location=Your_Latitude,Your_Longitude&radius=In_Metres&types=What_You_Want_To_Search&key=Your_API_KEY

对于地点类型的支持..查看this link

快乐编码:)

Answer 2

你可以从这里处理分类搜索。你可以有详细的知识

https://developers.google.com/maps/documentation/android/intents

如果您通过一般搜索词，Google 地图将尝试在您指定的经纬度附近找到符合您条件的位置。如果未指定位置，Google 地图将尝试查找附近的列表。例如：

// Search for restaurants nearby
Uri gmmIntentUri = Uri.parse("geo:0,0?q=restaurants");
Intent mapIntent = new Intent(Intent.ACTION_VIEW, gmmIntentUri);
mapIntent.setPackage("com.google.android.apps.maps");
startActivity(mapIntent);


// Search for restaurants in San Francisco
Uri gmmIntentUri = Uri.parse("geo:37.7749,-122.4194?q=restaurants");
Intent mapIntent = new Intent(Intent.ACTION_VIEW, gmmIntentUri);
mapIntent.setPackage("com.google.android.apps.maps");
startActivity(mapIntent);

加油站也可以这样做
