从我的应用程序，我打开默认的谷歌地图应用程序。
String uri = String.format（Locale.ENGLISH，geo：0,0？ q =％f，％f（％s）， locationList.get（1）.getLatitude（），locationList.get（1）.getLongitude（），My location）; Intent intent = new Intent（Intent.ACTION_VIEW，Uri.parse（uri））; Log.i（TAG，Uri is+ uri）; this.startActivity（intent）;这工作正常。但是，是否有可能传递一个坐标列表并将它们全部绘制出来，以便我可以创建一个路径？ 解决方案
字符串destination = locationList.get（1）.getLatitude（）+， + locationList.get 1）.getLongitude（）; Uri gmmIntentUri = Uri.parse（google.navigation：q =+ destination +& mode = d）; Log.e（TAG，Intent uri：+ gmmIntentUri.toString（））; Intent mapIntent = new Intent（Intent.ACTION_VIEW，gmmIntentUri）; mapIntent.setFlags（Intent.FLAG_ACTIVITY_NEW_TASK）; mapIntent.setPackage（com.google.android.apps.maps）; this.startActivity（mapIntent）;
这会以导航模式将地图从当前位置打开到指定的目的地。

From my app i am opening the default google map app. Here is how i am doing it.
String uri = String.format(Locale.ENGLISH, "geo:0,0?q=%f,%f(%s)", locationList.get(1).getLatitude(), locationList.get(1).getLongitude(),"My location"); Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(uri)); Log.i(TAG, "Uri is "+ uri); this.startActivity(intent);This is working fine. But is it possible to pass a list of coordinates and plot them all so i could create a path?
解决方案Here try this:
String destination = locationList.get(1).getLatitude()+"," +locationList.get(1).getLongitude(); Uri gmmIntentUri = Uri.parse("google.navigation:q="+destination+"&mode=d"); Log.e(TAG,"Intent uri : "+gmmIntentUri.toString()); Intent mapIntent = new Intent(Intent.ACTION_VIEW, gmmIntentUri); mapIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); mapIntent.setPackage("com.google.android.apps.maps"); this.startActivity(mapIntent);this will open map in navigation mode from your current location to the specified destination.
you can have a look at the below link to specify way points between your source and destination: developers.google/maps/documentation/urls/android-intents developers.google/maps/documentation/urls/guide
Let me know if you have any doubts.
