Android - 如何在具有特定位置、缩放级别和标记的 Android 应用程序中启动 Google 地图意图 [英] Android - How to launch Google map intent in android app with certain location, zoom level and marker

问题描述

地图意图不适用于特定缩放级别以及自定义标记

Map Intent not working with specific zoom level as well as custom marker

    float lat = 40.714728f;
    float lng = -73.998672f;

    String maplLabel = "ABC Label";
    final Intent intent = new Intent(android.content.Intent.ACTION_VIEW,
            Uri.parse("geo:0,0?q="+lat+","+lng+"&z=16 (" + maplLabel + ")"));
    startActivity(intent);

有人知道怎么回事吗?或者怎么做?我想在特定的缩放级别使用自定义标签标记显示某些 (lat,lng) 的地图.

Anybody know what is wrong? or how to do so? I want to show map of certain (lat,lng) with a custom label-marker at a specific zoom level.

推荐答案

尝试以下解决方案:

double latitude = 40.714728;
double longitude = -73.998672;
String label = "ABC Label";
String uriBegin = "geo:" + latitude + "," + longitude;
String query = latitude + "," + longitude + "(" + label + ")";
String encodedQuery = Uri.encode(query);
String uriString = uriBegin + "?q=" + encodedQuery + "&z=16";
Uri uri = Uri.parse(uriString);
Intent intent = new Intent(android.content.Intent.ACTION_VIEW, uri);
startActivity(intent);

功劳在这里:答案

我认为问题与标签中的空格有关.编码查询字符串将通过用有效字符替换空格来消除问题

I believe the problem had to do with the spaces in your label. Encoding the query string will eliminate the issue by replacing the spaces with valid characters
