Question

这有点奇怪，我按照Google Places API为我的Android应用添加自动完成功能。即使使用正确的API密钥，Google Places API请求也会因Android自动填充而被拒绝。我甚至尝试使用JSON客户端检查并请求两个GET / POST仍然是相同的错误，因为我确定我的代码遵循google api自动完成的集成。我没有找到解决错误的任何解决方案。一些答案建议使用place_id删除传感器。我不知道。请解释一下一个解决方案或建议，可以帮助我使自动完成工作正常。

Answer 1

嗨兄弟这样用你的api键试试这个url： https://maps.googleapis.com/maps/api/place/autocomplete/json?sensor=true&key= api key＆amp; language = en＆amp; input = kir

其工作经纪人。

Answer 2

它只适用于Android应用程序。不要在REST客户端中尝试它。而是尝试调试您的应用以查看响应。

Answer 4

所以我需要做的改变是因为我假设用place_id替换传感器，我的try catch也应该改为看起来像你的代码片段;

try {

        // Create a JSON object hierarchy from the results

        JSONObject jsonObj = new JSONObject(jsonResults.toString());

        JSONArray predsJsonArray = jsonObj.getJSONArray("predictions");

        // Extract the Place descriptions from the results

        resultList = new ArrayList<String>(predsJsonArray.length());

        for (int i = 0; i < predsJsonArray.length(); i++) {

            resultList.add(predsJsonArray.getJSONObject(i).getString(

            "description"));

        }

    } catch (JSONException e) {

        Log.e(TAG, "Cannot process JSON results", e);

    }

    return resultList;

然后我可以按照你的解释创建服务器密钥，我应该好好去。感谢

Hey guys now the autocomplete is working Jaswinder I just added place_id where you commented it out and wala! it works like a charm.

希望此代码可以帮助某人。我使用Key for browser application并在控制台中启用了Places api和Goople map api。

private class PlacesAutoCompleteAdapter extends ArrayAdapter<String>
        implements Filterable {
    private ArrayList<String> resultList;

    public PlacesAutoCompleteAdapter(Context context, int textViewResourceId) {
        super(context, textViewResourceId);
    }

    @Override
    public int getCount() {
        return resultList.size();
    }

    @Override
    public String getItem(int index) {
        return resultList.get(index);
    }

    @Override
    public Filter getFilter() {
        Filter filter = new Filter() {
            @Override
            protected FilterResults performFiltering(CharSequence constraint) {
                FilterResults filterResults = new FilterResults();
                if (constraint != null) {
                    // Retrieve the autocomplete results.
                    resultList = autocomplete(constraint.toString());

                    // Assign the data to the FilterResults
                    filterResults.values = resultList;
                    filterResults.count = resultList.size();
                }
                return filterResults;
            }

            @Override
            protected void publishResults(CharSequence constraint,
                    FilterResults results) {
                if (results != null && results.count > 0) {
                    notifyDataSetChanged();
                } else {
                    notifyDataSetInvalidated();
                }
            }
        };
        return filter;
    }
}

// Get array list of addresses
private ArrayList<String> autocomplete(String input) {

    ArrayList<String> resultList = null;

    HttpURLConnection conn = null;

    StringBuilder jsonResults = new StringBuilder();

    try {
        StringBuilder sb = new StringBuilder(PLACES_API_BASE

        sb.append("?sensor=true&key="

        + API_KEY);

        // for current country.Get the country code by SIM

        // If you run this in emulator then it will get country name is
        // "us".

        String cName = getCountryCode();

        if (cName != null) {
            countryName = cName;
        } else {
            countryName = "za";
        }
        sb.append("&components=country:" + countryName);

        }

    } catch (MalformedURLException e) {

        Log.e(TAG, "Error processing Places API URL", e);

        return resultList;

    } catch (IOException e) {

        Log.e(TAG, "Error connecting to Places API", e);

        return resultList;

    } finally {

            resultList.add(predsJsonArray.getJSONObject(i).getString(

        }
