Question

我正在开发一个非常基本的应用程序，我正在创建一个半径5000米的地理围栏，以我的位置为中心。

    public class MainActivity extends ActionBarActivity implements
    GooglePlayServicesClient.ConnectionCallbacks,
    GooglePlayServicesClient.OnConnectionFailedListener, LocationListener,
    com.google.android.gms.location.LocationListener,
    LocationClient.OnAddGeofencesResultListener {

private LocationClient mLocationClient;
private LocationRequest mLocationRequest;
// Milliseconds per second
private static final int MILLISECONDS_PER_SECOND = 1000;
// Update frequency in seconds
public static final int UPDATE_INTERVAL_IN_SECONDS = 5;
// Update frequency in milliseconds
private static final long UPDATE_INTERVAL = MILLISECONDS_PER_SECOND
        * UPDATE_INTERVAL_IN_SECONDS;
// The fastest update frequency, in seconds
private static final int FASTEST_INTERVAL_IN_SECONDS = 1;
// A fast frequency ceiling in milliseconds
private static final long FASTEST_INTERVAL = MILLISECONDS_PER_SECOND
        * FASTEST_INTERVAL_IN_SECONDS;

boolean mUpdatesRequested;
private Editor mEditor;
private SharedPreferences mPrefs;
private List<Geofence> mGeofenceLists = new ArrayList<Geofence>();

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_list_item);

    mUpdatesRequested = false;
    mPrefs = getPreferences(MODE_PRIVATE);
    mEditor = mPrefs.edit();

    // Create the LocationRequest object
    mLocationRequest = LocationRequest.create();
    // Use high accuracy
    mLocationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
    // Set the update interval to 5 seconds
    mLocationRequest.setInterval(UPDATE_INTERVAL);
    // Set the fastest update interval to 1 second
    mLocationRequest.setFastestInterval(FASTEST_INTERVAL);

    // Location Client Object
    mLocationClient = new LocationClient(this, this, this);

}

@Override
protected void onStart() {
    super.onStart();
    // Connect the client.
    mLocationClient.connect();
}

@Override
protected void onStop() {
    // Disconnecting the client invalidates it.
    mLocationClient.disconnect();
    super.onStop();
}

@Override
protected void onPause() {
    // TODO Auto-generated method stub
    super.onPause();
    // Save the current setting for updates
    mEditor.putBoolean("KEY_UPDATES_ON", mUpdatesRequested);
    mEditor.commit();
    super.onPause();
}

@Override
protected void onResume() {
    // TODO Auto-generated method stub
    super.onResume();

    /*
     * Get any previous setting for location updates Gets "false" if an
     * error occurs
     */
    if (mPrefs.contains("KEY_UPDATES_ON")) {
        mUpdatesRequested = mPrefs.getBoolean("KEY_UPDATES_ON", false);

        // Otherwise, turn off location updates
    } else {
        mEditor.putBoolean("KEY_UPDATES_ON", false);
        mEditor.commit();
    }
}

@Override
public void onConnectionFailed(ConnectionResult result) {
    // TODO Auto-generated method stub
    System.out.println("DISCONNECTED!!!!!!!!!!!!!!!!!!");
}

@Override
public void onConnected(Bundle connectionHint) {

    // Location location = mLocationClient.getLastLocation();

    Geofence geofence = new Geofence.Builder().setRequestId("geo1")
            .setTransitionTypes(Geofence.GEOFENCE_TRANSITION_ENTER)
            .setCircularRegion(89.535354, -88.575510, 5000)
            .setExpirationDuration(Geofence.NEVER_EXPIRE).build();

    mGeofenceLists.add(geofence);
    mLocationClient.addGeofences(mGeofenceLists,
            getTransitionPendingIntent(), this);

    if (true) { // Need to update when user is asking for updates with
                // mUpdatesRequested
        mLocationClient.requestLocationUpdates(mLocationRequest, this);

    }

}

private PendingIntent getTransitionPendingIntent() {
    // Create an explicit Intent
    PendingIntent geoFencePendingIntent = PendingIntent.getService(this, 0,
            new Intent(this, TransitionsIntentService.class),
            PendingIntent.FLAG_UPDATE_CURRENT);
    return geoFencePendingIntent;

}

}

我没有在代码中得到任何触发。是因为我已经在地理围栏中了??? 如何使用我创建的地理围栏来测试进入和退出点。

Answer 1

我试图自己使用MockLocations来触发围栏，但我无法使其发挥作用。你可以试试这个：

转到设置，开发者选项并允许mockLocations。
然后只需下载一个应用程序来更改你的gps位置，比如fakegps或类似的东西。

这样对我有用。
