Android啓動谷歌地圖來自變量的方向

Question

我想從變量edittext或textview啓動Google Maps方向任何人都可以幫助我？ 這是我的Java代碼：

StringBuilder stringbuilder = new StringBuilder("http://maps.google.com/maps?daddr="); 
    double d = -6.559759; 
    StringBuilder stringbuilder1 = stringbuilder.append(d).append(","); 
    double d1 = 106.785973; 
    Uri uri = Uri.parse(stringbuilder1.append(d1).toString()); 
    Intent intent = new Intent("android.intent.action.VIEW", uri); 
    startActivity(intent); 

Answer 1

嘗試這個 -

final Intent intent = new Intent(Intent.ACTION_VIEW,Uri.parse("http://maps.google.com/maps?f=d&saddr="+currentLatitude+","+currentLongitude+"&daddr="+dest_Latitude+","+dest_Longitude)); 
      intent.setClassName("com.google.android.apps.maps", "com.google.android.maps.MapsActivity"); 
      context.startActivity(intent);
