javascript - 如何在谷歌地图中使用邮政编码查找位置

Question

嘿

我正在使用谷歌地图完成搜索部分并在按城市名称搜索时获得结果。现在我必须做一些扩展功能，比如如果我提供邮政编码然后必须在 2 公里或 10 公里范围内搜索。我该怎么做它??
在这里看一个例子 http://www.hm.com/no/store-locator

试试这个代码...

那是从邮政编码获取纬度和经度...

public void locationFromPostCode(String postCode){

    geocoder1 = new Geocoder(this);
    try {
          List<Address> addresses1 = geocoder1.getFromLocationName(postCode, 1);
          if (addresses1 != null && !addresses1.isEmpty()) {
            Address address1 = addresses1.get(0);
            // Use the address as needed
            latitude_start = address1.getLatitude();
            longitude_start = address1.getLongitude();
            String message = "Latitude: "+address1.getLatitude()+", Longitude: "+address1.getLongitude();
            Toast.makeText(this, message, Toast.LENGTH_LONG).show();
          } else {
            // Display appropriate message when Geocoder services are not available
            Toast.makeText(this, "Unable to geocode zipcode", Toast.LENGTH_LONG).show(); 
          }
        } catch (IOException e) {
          // handle exception
        }
    }

对于该代码，您需要遵循...

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_MOCK_LOCATION"/>

您从邮政编码地点的纬度和经度代码中获取从纬度和经度，您可以获得位置...
