未找到当前位置时，未显示标记上的InfoWindow

Question

我正在开发一个实现MapsView的应用。在MapsView中，有一些标记，我点击其中一个标记，它会显示InfoWindow。如果找到我当前的位置，它工作正常。但问题是当我找不到当前位置时（GPS禁用），当我点击它时，标记没有显示InfoWindow。

这是我的代码

//Getting current location
private void getCurrentLocation() {
    mMap.clear();

    //Creating a location object
    if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION)
            == PackageManager.PERMISSION_GRANTED) {
        location = LocationServices.FusedLocationApi.getLastLocation(googleApiClient);
    } else {
        Toast.makeText(MapsActivity.this, "Anda harus menyetujuinya agar dapat menggunakan semua fitur yang ada", Toast.LENGTH_LONG).show();
        if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION)
                == PackageManager.PERMISSION_GRANTED) {
            location = LocationServices.FusedLocationApi.getLastLocation(googleApiClient);
        }
    }

    if (location != null) {
        //Getting longitude and latitude
        fromLongitude = location.getLongitude();
        fromLatitude = location.getLatitude();

        //Creating a LatLng Object to store Coordinates
        origin = new LatLng(fromLatitude, fromLongitude);

        mo=new MarkerOptions().position(origin).icon(BitmapDescriptorFactory.fromResource(R.mipmap.here));
        my_marker=mMap.addMarker(mo);
        my_marker.setTitle("I'm Here");
        my_marker.setSnippet("Starting point");
        my_marker.setDraggable(true);
    }
}

class GetInfo extends AsyncTask<String, Void, Boolean> {
    ProgressDialog dialog;

    @Override
    protected void onPreExecute() {
        super.onPreExecute();
        dialog = new ProgressDialog(MapsActivity.this);
        dialog.setMessage("Mohon tunggu");
        dialog.setTitle("Mendapatkan data...");
        dialog.show();
        dialog.setCancelable(true);
    }

    @Override
    protected Boolean doInBackground(String... urls) {
        try {
            HttpGet httppost = new HttpGet(urls[0]);
            HttpClient httpclient = new DefaultHttpClient();
            HttpResponse response = httpclient.execute(httppost);
            int status = response.getStatusLine().getStatusCode();
            if (status == 200) {

                HttpEntity entity = response.getEntity();
                String data = EntityUtils.toString(entity);
                JSONObject jsono = new JSONObject(data);

                JSONArray konten = jsono.getJSONArray("konten");
                mMarkersHashMap = new HashMap<Marker, MyMarker>();

                for (int i = 0; i < konten.length(); i++) {
                    HashMap<String,String> newMap=new HashMap<String,String>();
                    JSONObject object = konten.getJSONObject(i);
                    newMap.put("nama", object.getString("nama"));
                    newMap.put("deskripsi",object.getString("deskripsi"));

                    newMap.put("lat", object.getString("lat"));

                    array.add(newMap);
                }
                return true;
            }
        } catch (ParseException e1) {
            e1.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        } catch (JSONException e) {
            e.printStackTrace();
        }
        return false;
    }

    protected void onPostExecute(final Boolean result) {
        dialog.cancel();
        runOnUiThread(new Runnable() {
            @Override
            public void run() {
                if (!result) {

                    showInfo();
                }
                else {
                    for (int i = 0; i < array.size(); i++) {
                        HashMap<String, String> newMap = new HashMap<String, String>();
                        newMap = array.get(i);
                        mMyMarkersArray.add(new MyMarker(newMap.get("nama"), newMap.get("deskripsi"), newMap.get("foto"), newMap.get("marker"), Double.parseDouble(newMap.get("lat")), Double.parseDouble(newMap.get("lng"))));
                    }
                    plotMarkers(mMyMarkersArray);
                }
                }
        });

    }
}

@Override

    getCurrentLocation();

        Log.e(getClass().getSimpleName(), "Tidak dapat mengambil gambar!");
    }

    @Override
    public void onSuccess() {
        if (marker != null && marker.isInfoWindowShown()) {
            marker.hideInfoWindow();
            marker.showInfoWindow();
        }
    }
}

任何答案都将不胜感激。

感谢。

我通过在marker.showInfoWindow();

中添加此代码onMarkerClick来解决问题
