使用这样的：

for (int i = 0; i < yourArrayList.size(); i++) {

  double lati=Double.parseDouble(pins.get(i).latitude);
  double longLat=Double.parseDouble(pins.get(i).longitude);
  MAP.addMarker(new MarkerOptions().position(new LatLng(lati,longLat)).title(pins.get(i).pinname).snippet(pins.get(i).address));
 }

或者你也可以使用这样的：

Or you can also use this:

 for(int pin=0; pin<pins.size(); pin++)
            {
                LatLng pinLocation = new LatLng(Float.parseFloat(pins.get(pin).latitude), Float.parseFloat(pins.get(pin).longitude));
                Marker storeMarker = map.addMarker(new MarkerOptions()
                .position(pinLocation)
                .title(pins.get(pin).pinname)
                .snippet(pins.get(pin).address)
                );
            }

其中纬度和经度是您具有存储在你的ArrayList不同名称的字符串.....

where latitude and longitude is the String to which you have store in your arraylist with different name.....
