打开地图以显示从当前位置到Intent-Android的方向 [英] Open map to show direction from current location through intent-Android

问题描述

我的android应用中有许多经度.我想知道如何通过意图打开选择器或Google Map App，并显示从当前位置到该纬度和经度的方向.就像我有lat = 28.605989，lon = 77.372970，我的当前位置在某个地方，所以当我单击按钮时在我的应用中，这些纬度会通过意图传递，并会显示从我当前位置到这些纬度的方向.谢谢.

推荐答案

要长时间将用户导航到目的地，我们可以使用类似的

To navigate user to destination lat long, we can use something like this

Intent intent = new Intent(android.content.Intent.ACTION_VIEW, 
Uri.parse("http://maps.google.com/maps?daddr=28.605989,77.372970"));
startActivity(intent);

这里.我们仅传递目标纬度daddr=28.605989,77.372970，因此默认情况下，您当前的位置将是源位置.

Here . we are passing just destination lat long daddr=28.605989,77.372970, so by default, your current location will be source location.

要在您的网址中添加其他信息.

To add extra information with your url .

String my_data= String.format(Locale.ENGLISH, "http://maps.google.com/maps?daddr=20.5666,45.345(My Destination Place)");

Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(my_data));
intent.setPackage("com.google.android.apps.maps");
startActivity(intent);
