android - geocoder.getFromLocation 返回 null

Question

我的代码:

                 try
                {

                            Geocoder geocoder;
                        List<Address> addresses;

            geocoder = new Geocoder(LocationActivity.this, Locale.getDefault());

            addresses = geocoder.getFromLocation(longitude,latitude,1);

            Toast.makeText(LocationActivity.this, addresses.size() + "", Toast.LENGTH_LONG).show();

            String address = addresses.get(0).getAddressLine(0);
            String city = addresses.get(0).getAddressLine(0);
            String country = addresses.get(0).getAddressLine(0);

            Toast.makeText(LocationActivity.this, address + "  " + city + " " + country, Toast.LENGTH_LONG).show();

        }
        catch(Exception e)
        {
            Toast.makeText(LocationActivity.this,e.toString(), Toast.LENGTH_LONG).show();
        }

这是我从经度和纬度获取地址的代码。但每次 addresses.size 返回 0

谁能帮帮我

我找到了解决方案...在 getFromLocation() 上按住 Ctrl 并转到 Geocoder.class 。然后下载您的 android API 的源代码并重新启动您的项目。然后你看到它的工作
