Question

我已经完成了可以搜索的所有解决方案。我启用了与我的项目相关的API并且慢慢地制作了API密钥（浏览器，android），当然但没有一个正在运行。根据{{3}}，我的API密钥格式错误或缺失。有没有办法在我运行项目时检查清单中的值是变化还是变为空？

如果您已完成Google安装程序，那么只需尝试使用此网址，它一直在为我工作......

private String getPlacesApiUrl() {
    String url = "";
    String location = String.valueOf(currentLocation.latitude)+","+String.valueOf(currentLocation.longitude);       
    String radius = "5000";
    String type = "hospital";       
    String sensor = "false";
    String key = "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX";

    try {
        url = "https://maps.googleapis.com/maps/api/place/search/json"
            + "?location=" +  URLEncoder.encode(location, "UTF-8")
            + "&type=" + URLEncoder.encode(type, "UTF-8")
            + "&radius=" + URLEncoder.encode(radius, "UTF-8")
            + "&sensor=" + URLEncoder.encode(sensor, "UTF-8")
            + "&key=" + URLEncoder.encode(key, "UTF-8");
    } catch (UnsupportedEncodingException e) {
        e.printStackTrace();
    }
    Log.d("url",url);
    return url;
}

但请确保您使用的是浏览器密钥

祝你好运。

我通过使用从教程中找到的代码解决了这个问题。希望这对有同样麻烦的人有所帮助。

我制作了PlaceAPI课程

class PlacesAutoCompleteAdapter extends ArrayAdapter<String> implements Filterable {

    ArrayList<String> resultList;

    Context mContext;
    int mResource;

    PlaceAPI mPlaceAPI = new PlaceAPI();

    public PlacesAutoCompleteAdapter(Context context, int resource) {
        super(context, resource);

        mContext = context;
        mResource = resource;
    }

    @Override
    public int getCount() {
        // Last item will be the footer
        return resultList.size();
    }

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

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

                    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;
    }
}

并制作了一个适配器PlacesAutoCompleteAdapter

autocomplete = (AutoCompleteTextView) findViewById(R.id.autocomplete);
        autocomplete.setAdapter(new PlacesAutoCompleteAdapter(this, R.layout.autocomplete_list_item));
        autocomplete.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
                // Get data associated with the specified position
                // in the list (AdapterView)
                place = (String) parent.getItemAtPosition(position);
                //Toast.makeText(this, description, Toast.LENGTH_SHORT).show();
            }
        });

然后在自动完成中使用适配器：
