Android: Why wont this code let me set text (float?)?

    LocationManager locationManager = (LocationManager) getSystemService(LOCATION_SERVICE);
    Criteria criteria = new Criteria();
    String bestProvider = locationManager.getBestProvider(criteria, false);
    Location location = locationManager.getLastKnownLocation(bestProvider);
    SharedPreferences settings = getSharedPreferences("cars4sale",0);
    SharedPreferences.Editor GPS = settings.edit();
    GPS.putFloat("latitude", (float)location.getLatitude());
    GPS.putFloat("longitude", (float)location.getLongitude());
    GPS.commit();

    TextView GPSTV = (TextView)findViewById(R.id.GPSTV);
    SharedPreferences coords = getSharedPreferences("cars4sale",0);
    String gpsstr = GPS.getFloat("gps", "");    
    GPSTV.setText(gpsstr);

The main problem is eclipse wants me to change getFloat to putFloat and then when I 开发者_如何学Godo that it wants me to do getInt and then goes in a loop between float and Int. I just want to store a number to a textview field!

Because coords is a sharedpreferences, and I don't think you want to setText there?

Don't you mean

GPSTV.setText(gpsstr);

This:

String gpsstr = GPS.getFloat("gps", "");    

Doesn't work, because GPS is your Editor, not your sharedpreferences. You need this

String gpsstr = String.valueOf(coords.getFloat("gps", 0));    
GPSTV.setText(gpsstr);
