android - Status{statusCode=NETWORK_ERROR, resolution=null} 即使将 "AutocompleteFilter"作为 null 传递

Question

作为 Android 的新手，我正在尝试为一个项目接触 google Map API。我想为谷歌地图实现 AutoComplete。无论我做什么，我都会不断收到 Status{statusCode=NETWORK_ERROR, resolution=null}。

我提到了一些 SO 问题，例如:

• Question 1
• Question 2

但是我无法解决这个问题。我将 mPlaceFilter 作为 null 传递，但 status.toString() 仍返回相同的错误

    private ArrayList<PlaceAutocomplete> getAutocomplete(CharSequence constraint) {
    if (mGoogleApiClient.isConnected()) {
        Log.i("", "Starting autocomplete query for: " + constraint);

        // Submit the query to the autocomplete API and retrieve a PendingResult that will
        // contain the results when the query completes.
        PendingResult<AutocompletePredictionBuffer> results =
                Places.GeoDataApi.getAutocompletePredictions(mGoogleApiClient, constraint.toString(),mBounds, mPlaceFilter);

        // This method should have been called off the main UI thread. Block and wait for at most 60s
        // for a result from the API.
        AutocompletePredictionBuffer autocompletePredictions = results.await(60, TimeUnit.SECONDS);

        // Confirm that the query completed successfully, otherwise return null
        final Status status = autocompletePredictions.getStatus();
        if (!status.isSuccess()) {
            Toast.makeText(mContext, "Error contacting API:: " + status.toString(),Toast.LENGTH_SHORT).show();
            Log.e("", "Error getting autocomplete prediction API call: " + status.toString());
            autocompletePredictions.release();
            return null;
        }

        Log.i("", "Query completed. Received " + autocompletePredictions.getCount()
                + " predictions.");

        // Copy the results into our own data structure, because we can't hold onto the buffer.
        // AutocompletePrediction objects encapsulate the API response (place ID and description).

        Iterator<AutocompletePrediction> iterator = autocompletePredictions.iterator();
        ArrayList resultList = new ArrayList<>(autocompletePredictions.getCount());
        while (iterator.hasNext()) {
            AutocompletePrediction prediction = iterator.next();
            // Get the details of this prediction and copy it into a new PlaceAutocomplete object.
            resultList.add(new PlaceAutocomplete(prediction.getPlaceId(), prediction.getFullText(null)));


        }

        // Release the buffer now that all data has been copied.
        autocompletePredictions.release();

        return resultList;
    }
    Log.e("", "Google API client is not connected for autocomplete query.");
    return null;
}

在logcat中，我可以看到

Answer 1

这是我在之前的项目中所做的，它运行良好，可能对您有所帮助。

// Add this code in onCreate()
mGoogleApiClient = new GoogleApiClient.Builder(this)
            .enableAutoManage(this, 0 , MainActivity.this)
            .addApi(Places.GEO_DATA_API)
            .build();
mGoogleApiClient.connect();


// AutoCompleteTextView AddOnTextChangeListener.
to_auto_txt.addTextChangedListener(new TextWatcher() {

        public void afterTextChanged(Editable s) {
        }

        public void beforeTextChanged(CharSequence s, int start, int count,
                                      int after) {
        }

        public void onTextChanged(CharSequence s, int start, int before,
                                 int count) {

                if (search_text.length <= 1) {
                    names = new ArrayList<String>();
                    parse = new paserdata();
                    parse.execute();
                }
          }
    });

解析数据是异步任务。

 public class paserdata extends AsyncTask<Void, Integer, Void> {
    @Override
    protected Void doInBackground(Void... params) {

        if (mGoogleApiClient.isConnected()) {
            PendingResult<AutocompletePredictionBuffer> results = Places.GeoDataApi.getAutocompletePredictions(mGoogleApiClient, search_text[0], BOUNDS_INDIA, null);
            AutocompletePredictionBuffer autocompletePredictions = results.await(60, TimeUnit.SECONDS);
            final com.google.android.gms.common.api.Status status = autocompletePredictions.getStatus();
            if (!status.isSuccess()) {
                System.out.println("Error getting autocomplete prediction API call: " + status.toString());
                autocompletePredictions.release();
                return null;
            }
            System.out.println("Query completed. Received " + autocompletePredictions.getCount() + " predictions.");
            Iterator<AutocompletePrediction> iterator = autocompletePredictions.iterator();
            ArrayList resultList = new ArrayList<>(autocompletePredictions.getCount());

            while (iterator.hasNext()) {
                AutocompletePrediction prediction = iterator.next();
                names.add(prediction.getFullText(STYLE_BOLD).toString());
            }
            // Release the buffer.
            autocompletePredictions.release();
        } 
        return null;
    }

    @Override
    protected void onPostExecute(Void result) {
        // adp is ArrayAdapter object which declare globally.
        adp = new ArrayAdapter<String>(getApplicationContext(),
                android.R.layout.simple_list_item_1, names) {
            @Override
            public View getView(int position, View convertView,
                                ViewGroup parent) {
                View view = super.getView(position, convertView, parent);
                TextView text = (TextView) view
                        .findViewById(android.R.id.text1);
                text.setTextColor(Color.BLACK);
                return view;
            }
        };
       // AutoCompleteTextView.
       to_auto_txt.setAdapter(adp);
    }
}

最后不要忘记断开 mGoogleApiClient 的连接。

@Override
public void onStop() {
    mGoogleApiClient.disconnect();
    super.onStop();
}

您也可以在 onDestroy() 内部断开连接。
