我在我的 ionic 应用程序 android 版本中面临有关地理围栏的问题。多次调用半径输出/输入条目。当一个人可以进入半径或从半径出去时，它应该正确调用一次。

我们也在使用事件总线。

在这里，我们在 android 文件中有代码

调用地理围栏

int geofenceTransition = geofencingEvent.getGeofenceTransition();
    // Test that the reported transition was of interest.
    if (geofenceTransition == Geofence.GEOFENCE_TRANSITION_ENTER ||
            geofenceTransition == Geofence.GEOFENCE_TRANSITION_EXIT) {

        Intent i = new Intent("geofenceStatus");
        if (geofenceTransition == Geofence.GEOFENCE_TRANSITION_EXIT) {
            status = "exit";
        } else {
            if (status.equals("exit")) status = "reenter";
            else status = "enter";
        }

        Date currentTime = Calendar.getInstance().getTime();
        i.putExtra("status", status);
        LocalBroadcastManager.getInstance(this).sendBroadcast(i);
        EventBus.getDefault().post(status);

        // Get the geofences that were triggered. A single event can trigger multiple geofences.
        List<Geofence> triggeringGeofences = geofencingEvent.getTriggeringGeofences();

        // Get the transition details as a String.
        String geofenceTransitionDetails = getTransitionString(geofenceTransition);//getGeofenceTransitionDetails(geofenceTransition, triggeringGeofences);

        // Send notification and log the transition details.
        sendNotification(geofenceTransitionDetails);
    } else {
        // Log the error.
    }

添加地理围栏

mGeofencingClient.addGeofences(getGeofencingRequest(), getGeofencePendingIntent())
        .addOnFailureListener(e -> {
          Log.e(TAG, "onFailure: " + e.toString());
          //Toast.makeText(activity, "Failed to add geoFence, " + e.toString(), Toast.LENGTH_SHORT).show();
        })
        .addOnCompleteListener(task -> {
          Log.d(TAG, "onComplete: GeoFence added status: " + task.isSuccessful());
          if (task.isSuccessful()) {
            Calendar c = Calendar.getInstance();
            geofenceCreateDate = String.valueOf(c.get(Calendar.DATE));
            Toast.makeText(activity, "GeoFence Added", Toast.LENGTH_SHORT).show();
            PrefUtils.saveToPrefs(activity, "geofenceCreateDate", geofenceCreateDate);
          }
        });

删除地理围栏

mGeofencingClient.removeGeofences(getGeofencePendingIntent()).addOnCompleteListener(task -> {
    Log.d(TAG, "removeGeofences: GeoFence remove status: " + task.isSuccessful());
    PrefUtils.removeFromPrefs(activity, "GEO_STATUS");
    //if (task.isSuccessful())
    // Toast.makeText(activity, "GeoFence Removed", Toast.LENGTH_SHORT).show();
  });

客户端调用请求如下

client.newCall(request).enqueue(new Callback() {
  @Override
  public void onFailure(Call call, IOException e) {
    Log.e(TAG, "onFailure: api failed" + e.getLocalizedMessage());
    call.cancel();
  }

  @Override
  public void onResponse(Call call, Response response) {
    try {
      //response.body() can be consumed only once so use only jsonData
      String jsonData = response.body().string();
      Log.d(TAG, "onResponse: " + jsonData);

      JSONObject jsonObj = new JSONObject(jsonData);
      String status = jsonObj.getString("status");
      if (status != null && status.equals("success")) {
        JSONArray jsonRes = jsonObj.getJSONArray("result");
        JSONObject obj = jsonRes.getJSONObject(0);

        latitude = Double.parseDouble(obj.getString("latitude"));
        longitude = Double.parseDouble(obj.getString("longitude"));
        //GEOFENCE_RADIUS_IN_METERS = Integer.parseInt(obj.getString("geofencing_metre"));
        removeGeofence();
        addGeoFence();
      }
    } catch (Exception e) {
      e.printStackTrace();
    }
  }
});

这是我们打印的一些日志，显示了多个调用
