Android的 - 如何启动谷歌地图意图在某些位置，缩放级别和标记Android应用程序 [英] Android - How to launch Google map intent in android app with certain location, zoom level and marker

问题描述

地图意图不工作与特定的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);

任何人都知道什么是错的？或者该怎么办呢？ 我想显示地图一定的（纬度，经度）与自定义标签，标记在一个特定的缩放级别。

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

请尝试以下解决方案：

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);

幸得这里：回答

我认为这个问题必须做在你的标签空间。编码的查询字符串将通过有效字符代替空格消除此问题

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
