My Basic UI

I have a very basic UI where i want the user to able to save the latitude and longitute of the location they want to set a geofence to. What I'm wondering is how do i get both latitude and longitude and convert it into latlng and then pass the value into my map activity into an array list.Any help would be greatly Appreciated.

ApprovedAreas = new ArrayList<>();

    ApprovedAreas.add(new LatLng(37.4205940 ,-122.044 ));
    ApprovedAreas.add(new LatLng(37.459979 ,-122.138770 ));
    ApprovedAreas.add(new LatLng(37.4475940 ,-122.9044 ));

  • if you want to pass data between activities you should use `Bundle` check this : https://stackoverflow.com/questions/2091465/how-do-i-pass-data-between-activities-in-android-application – Farid Aug 08 '20 at 13:53

In this activity

    ArrayList<LatLng> areas  =  new ArrayList<LatLng>();
    savezone.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    areas.add(new LatLng(Double.parseDouble(latitude.getText().toString()),Double.parseDouble(longitude.getText().toString()));
                }
            }); 


gotomap.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                  Intent i = new Intent(currentactivity.this, mapactivity.class);
                 i.putParcelableArrayListExtra("areas", areas);
startActivity(intent);
                }
            });

In mapactivity

ArrayList<LatLng> areas  =  getIntent().getExtras().getParcelableArrayList("areas");

  • use Double.parseDouble to convert string to double – aryanknp Aug 08 '20 at 15:01
