将地点自动填充API限制到特定国家/地区的城市

问题描述

我使用Play Services的 PlaceAutocompleteApi ，我想要做的是限制自动完成到特定的国家&只有城市。例如。所有的城市都只能说印度。我使用 AutocompleteFilter 来做到这一点，但我不知道要在哪里指定我想要限制的国家/地区。

这是我的代码

  List< Integer> autocompleteFilter = new ArrayList<>（）; 
 // autocompleteFilter.add（Place.TYPE_COUNTRY）; 
 // autocompleteFilter.add（Place.TYPE_LOCALITY）; 
 
 
 mAdapter = new PlaceAutocompleteAdapter（mContext，R.layout.layout_location_text，
 mGoogleApiClient，BOUNDS，AutocompleteFilter.create（autocompleteFilter））; 
 mTxtLocation.setAdapter（mAdapter）; 
 
 mTxtLocation.setOnItemClickListener（mAutocompleteClickListener）; 
  

对此有何看法？

解决方案

要做到这一点的方法是将国家作为组件参数添加到Web服务URL：

  StringBuilder sb = new StringBuilder（PLACES_API_BASE + TYPE_AUTOCOMPLETE + OUT_JSON）; 
 sb.append（？key =+ API_KEY）; 
 sb.append（& components = country：in）; 
  

对于城市，您可以使用 administrative_area_level_3 标签：

  sb.append（& components = administrative_area_level_3：bengaluru）; 
  

或者 locality 标签：

  sb.append（& components = locality：redmond）;

I am using PlaceAutocompleteApi from Play Services, what I want to do is restrict auto-complete to specific country & city only. Eg. All cities from lets say India only. I am using AutocompleteFilter to do so but I don't know where to specify country that I want to restrict.

Here is my code

        List<Integer> autocompleteFilter = new ArrayList<>();
//        autocompleteFilter.add(Place.TYPE_COUNTRY);
//        autocompleteFilter.add(Place.TYPE_LOCALITY);


        mAdapter = new PlaceAutocompleteAdapter(mContext,R.layout.layout_location_text,
                mGoogleApiClient, BOUNDS, AutocompleteFilter.create(autocompleteFilter));
        mTxtLocation.setAdapter(mAdapter);

        mTxtLocation.setOnItemClickListener(mAutocompleteClickListener);

any thoughts on this?

解决方案

The way to do that is to add the country as the components parameter to the web service URL:

StringBuilder sb = new StringBuilder(PLACES_API_BASE + TYPE_AUTOCOMPLETE + OUT_JSON);
sb.append("?key=" + API_KEY);
sb.append("&components=country:in");

For cities you can use either the administrative_area_level_3 tag:

sb.append("&components=administrative_area_level_3:bengaluru");

or alternatively the locality tag:

sb.append("&components=locality:redmond");
