模仿Android location provider

public void onCreate(Bundle savedInstanceState) {

 super.onCreate(savedInstanceState);
 setContentView(R.layout.main);

 ((TextView) this.findViewById(R.id.textView)).setText("Something else");

 // LocationManager locationManager = (LocationManager)
 // getSystemService(Context.LOCATION_SERVICE);
 // locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER,
 // 0, 0, this);

 LocationManager locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);

 String mocLocationProvider = LocationManager.GPS_PROVIDER;
 locationManager.addTestProvider(mocLocationProvider, false, false,
 false, false, true, true, true, 0, 5);
 locationManager.setTestProviderEnabled(mocLocationProvider, true);
 locationManager.requestLocationUpdates(mocLocationProvider, 0, 0, this);

 try {

 List data = new ArrayList();
 InputStream is = getAssets().open("data.txt");
 BufferedReader reader = new BufferedReader(new InputStreamReader(is));
 String line = null;
 while ((line = reader.readLine()) != null) {

 data.add(line);
 }
 Log.e(LOG_TAG, data.size() + " lines");

 new MockLocationProvider(locationManager, mocLocationProvider, data).start();

 } catch (IOException e) {

 e.printStackTrace();
 }
 } 
public class MockLocationProvider extends Thread {

    private List data;

    private LocationManager locationManager;

    private String mocLocationProvider;

    private String LOG_TAG = "faren";

    public MockLocationProvider(LocationManager locationManager,
            String mocLocationProvider, List data) throws IOException {

        this.locationManager = locationManager;
        this.mocLocationProvider = mocLocationProvider;
        this.data = data;
    }

    @Override
    public void run() {

        for (String str : data) {

            try {

                Thread.sleep(1000);

            } catch (InterruptedException e) {

                e.printStackTrace();
            }

            // Set one position
            String[] parts = str.split(",");
            Double latitude = Double.valueOf(parts[0]);
            Double longitude = Double.valueOf(parts[1]);
            Double altitude = Double.valueOf(parts[2]);
            Location location = new Location(mocLocationProvider);
            location.setLatitude(latitude);
            location.setLongitude(longitude);
            location.setAltitude(altitude);

            Log.e(LOG_TAG, location.toString());

            // set the time in the location. If the time on this location
            // matches the time on the one in the previous set call, it will be
            // ignored
            location.setTime(System.currentTimeMillis());

            locationManager.setTestProviderLocation(mocLocationProvider,
                    location);
        }
    }
以上就是 Android location provider mock 从文本调用数据
