In Android is there some kind of object to save GPS position?

  • 772

Is there some type of variable or object in Java (Android) to save GPS positions, that is, each point is made up of latitude and the other longitude?

For example, to be able to save the location of Madrid :

Latitude:  40.416775
Longitude: -3.703790

and that allows you to add multiple locations, like a list.

    A simple example of use and how to add is added based on @Fabricio's answer :

    LatLng pos = new LatLng(40.416775, -3.703790);
double lat = pos.latitude; //getLatitude
double lng = pos.longitude;//getLongitude

    You can add it like this (selecting the revision/version you want):

    dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    //..
    compile 'com.google.android.gms:play-services-maps:8.3.0'
}

    You can check for more information here: https://developers.google.com/android/guides/setup

    About the second part of your question you can create an arrayor listor whatever you need from the object LatLng.

    Simple example based on pointY[], and pointX[](The dots are random numbers):

    double pointY[]={10.0000,10.5000,100.3000,100.2222}
double pointX[]={3.0000, 7.3333, 9.1111,  9.11111}

List<LatLng> puntos=new ArrayList<LatLng>();

for (int i = 0 ; i < pointX.length; i++){
    puntos.add(new LatLng(pointX[i],pointY[i]));
};

  2. The Object you mention is found in the Google Maps library for Android and is LatLng, if you are not using this library you can create a class that is composed of a Latitude( double) and a Longitude( double).

    Here is the link to the class documentation .
