谷歌导航意图 [英] Google Navigation intent

问题描述

我想直接从我的应用程序启动谷歌导航等，这将导航我从一个起始地址到达目的地址。所以我的纬度和经度坐标为起点和目的地址，并想获得导航这些。但我无法弄清楚如何提供一个起始地址。导航只用我的GPS获得我的当前信息。这是我发起的意图：

 字符串MLAT =46.849861;
        串mLong = -  120.541992;
        字符串DLAT =38.062419;
        字符串dLong =-99.173584;
        意向意图=新的意图（Intent.ACTION_VIEW，Uri.parse（google.navigation：Q =+ DLAT +，+ dLong））;
        intent.addFlags（Intent.FLAG_ACTIVITY_NEW_TASK）;
        startActivity（意向）;
 

解决方案

您可以做这样

 意向意图=新的意图（android.content.Intent.ACTION_VIEW，
    Uri.parse（http://maps.google.com/maps?saddr=20.344,34.34&daddr=20.5666,45.345））;
startActivity（意向）;
 

I'm trying to launch Google Navigation directly from my application such that it would navigate me from a start address to a destination address. So I have the Latitude and Longitude coordinates for both start and destination address and would like to get the navigation for those. But I can't figure out how to provide a start address. Navigation only uses my GPS to obtain my current info. This is how I launch the intent:

        String mLat = "46.849861";
        String mLong ="-120.541992";
        String dLat = "38.062419";
        String dLong = "-99.173584";
        Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("google.navigation:q=" +dLat+","+dLong));
        intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        startActivity(intent);

解决方案

You can do it this way

Intent intent = new Intent(android.content.Intent.ACTION_VIEW, 
    Uri.parse("http://maps.google.com/maps?saddr=20.344,34.34&daddr=20.5666,45.345"));
startActivity(intent);
