setTestProviderLocation()不会触发onLocationChanged()的调用

Question

我正在尝试使用这段代码:

在Android中测试GPS

问题是,当我运行测试时,永远不会调用onLocationChanged():

public class LocationTest0 extends AndroidTestCase implements LocationListener {
private Location received = null;
public void testExample() {
    LocationManager lm = (LocationManager)this.getContext().getSystemService(Context.LOCATION_SERVICE);
    String testProvider = "Test";

    if (null == lm.getProvider(testProvider)){
        lm.addTestProvider(testProvider, false, false, false, false, false, false, false, Criteria.POWER_LOW, Criteria.ACCURACY_FINE);
    }

    lm.setTestProviderEnabled(testProvider, true);
    lm.requestLocationUpdates(testProvider, 0, 0, this);
    lm.setTestProviderStatus(testProvider, LocationProvider.AVAILABLE, null, System.currentTimeMillis());

    Location location = new Location(testProvider);
    location.setLatitude(1.0);
    location.setLongitude(2.0);
    location.setTime(System.currentTimeMillis());
    lm.setTestProviderLocation(testProvider, location);

    Assert.assertFalse("Received Location is null", received == null );

    lm.removeTestProvider(testProvider);
}
@Override
public void onLocationChanged(Location location) {
    received = location;
    Log.d("LocationTest0", "onLocationChanged CALLED");
    // Never gets called
}

这对我有用

locationManager.addTestProvider(mocLocationProvider, false, false,
                    false, false, true, true, true, 0, 5);
locationManager.setTestProviderEnabled(mocLocationProvider, true);

.

Location mockLocation = new Location(mocLocationProvider); // a string
mockLocation.setLatitude(location.getLatitude());  // double 
mockLocation.setLongitude(location.getLongitude()); 
mockLocation.setAltitude(location.getAltitude()); 
mockLocation.setTime(System.currentTimeMillis()); 
locationManager.setTestProviderLocation( mocLocationProvider, mockLocation); 

.

同样在Android手机设置中,请确保勾选"允许模拟位置"复选框
