Change Map Type in Android Map App

Question

I'm very new to programming. I'm taking a mobile development class and this is all new to me. I have created a very basic Android app in Android studio that shows a standard Google Map. I need to create buttons on the app to change the map from normal, to satellite, terrain, and hybrid. I've been searching around here and on multiple other sources, but I don't know where to begin, or where to put the code I find on other sites. Can anyone help? I'm sure this is fairly easy, I just don't know what to do.

Thanks!

Answer 1

You can use option menu for that

   public boolean onOptionsItemSelected(MenuItem item) {
      switch (item.getItemId()) {
      case MENU_MyLocation:
       //startActivity(new Intent(this, MyLocation.class));
       return(true);
      case MENU_LocationCar:
       startActivity(new Intent(this, Gps.class));
       return(true);
      case MENU_Satellite:
          map.setMapType(GoogleMap.MAP_TYPE_SATELLITE);
          map.invalidate();
           return(true);
      case MENU_Terrain:
          map.setMapType(GoogleMap.MAP_TYPE_TERRAIN);
          map.invalidate();
       return(true);
      }

      return(super.onOptionsItemSelected(item));
    }

you can also add more

googleMap.setMapType(GoogleMap.MAP_TYPE_HYBRID);
 googleMap.setMapType(GoogleMap.MAP_TYPE_NORMAL);
 googleMap.setMapType(GoogleMap.MAP_TYPE_SATELLITE);
 googleMap.setMapType(GoogleMap.MAP_TYPE_TERRAIN);

Answer 2

to change map type , use this inside your onMapReady() .

 googleMap.setMapType(GoogleMap.MAP_TYPE_HYBRID);
 googleMap.setMapType(GoogleMap.MAP_TYPE_NORMAL);
 googleMap.setMapType(GoogleMap.MAP_TYPE_SATELLITE);
 googleMap.setMapType(GoogleMap.MAP_TYPE_TERRAIN);
