Question

我的应用程序在我调用下面的方法后崩溃了，我确定我可以从我的谷歌地图api获得纬度和经度，是因为googleurl ???错误发生在HttpPost httppost = new HttpPost（url） ;当我检查logcat时。

public String  getAddressUrl(Context context) {
            String responseText = null;
             //String latitude = "38.89";
             //String longitude  = "-77.03";
            String googleurl = "http://maps.google.com/maps/geo?";//url
            Log.v("TAG" , "Latitude is: " + mLocationClient.getLastLocation().getLatitude() + "Longitude is:" + mLocationClient.getLastLocation().getLongitude());
            StringBuilder sbuilder = new StringBuilder();
            sbuilder.append(googleurl);
            sbuilder.append("q = " + mLocationClient.getLastLocation().getLatitude() + "," + mLocationClient.getLastLocation().getLongitude());
            sbuilder.append("&output=responseText&sensor=true");
            String url = sbuilder.toString();

            Log.v("TAG", "url is: " + url);
            try {
                DefaultHttpClient httpclient = new DefaultHttpClient();
                HttpPost httppost = new HttpPost(url);
                HttpResponse httpresponse = httpclient.execute(httppost);
                HttpEntity httpentity = httpresponse.getEntity();
                InputStream is = httpentity.getContent();
                BufferedReader reader = new BufferedReader(
                    new InputStreamReader(is, "iso-8859-1"), 8);
                StringBuilder sb = new StringBuilder();
                String line = null;
                while((line = reader.readLine()) != null) {
                    sb.append(line + "\n");
                }
                is.close();
                responseText = sb.toString();
            }
            catch(ClientProtocolException e) {
                e.printStackTrace();
            }
            catch (IOException e) {
                e.printStackTrace();
            }
            return responseText;
        }

logcat的：

您可以尝试更改：

sbuilder.append(googleurl);
sbuilder.append("q = " + mLocationClient.getLastLocation().getLatitude() + "," + mLocationClient.getLastLocation().getLongitude());
sbuilder.append("&output=responseText&sensor=true");
String url = sbuilder.toString();

为：

    googleurl+="q="+mLocationClient.getLastLocation().getLatitude()+","+mLocationClient.getLastLocation().getLongitude()+"&output=responseText&sensor=true&language=en-EN";

我已经在最后添加了语言参数，因为有时google会将格式化的地址返回给我其他语言:) 或者只是删除＆＃34;＆＃34;中的空格。括号。我记得你不应该在＆＃34;＆＃34;中使用空格。引用，如果你想要它是一个网址。此外，您应该将此字符串编码为URL格式。如果要使用普通空格，则应将其更改为字符串中的％20。
