我试图让这段代码工作:
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
}
