Question

我已生成Current location值，我正在动态地将其传递给URL。我在Logcat中获得Latitude和'经度'的价值。但目前尚未生成LatLongUrl的动态URl。

Log.d(String.valueOf(mLastLocation.getLatitude()),"Latitude");
                    Log.d(String.valueOf(mLastLocation.getLongitude()),"Longitude");


                //urlJsonObj = "https://maps.googleapis.com/maps/api/place/nearbysearch/json?location=21.2150756,72.8880545&radius=500&type=hospital&key=AIzaSyBldIefF25dfjjtMZq1hjUxrj4T4hK66Mg";

                urlJsonObj = "https://maps.googleapis.com/maps/api/place/nearbysearch/json?location="+String.valueOf(mLastLocation.getLatitude()+","+String.valueOf(mLastLocation.getLongitude()+"&radius=500&type=hospital&key=AIzaSyBldIefF25dfjjtMZq1hjUxrj4T4hK66Mg";
                Log.d(urlJsonObj,"LatLongUrl");

Logcat显示如下：生成Latitude和'Longitude'的值但当前未生成LatLongUrl的动态URl。

    04-20 15:00:45.477 3209-3209/com.example.chaitanya.nearbyplace D/21.225225225225223: Latitude
04-20 15:00:45.477 3209-3209/com.example.chaitanya.nearbyplace D/72.8905100797212: Longitude

                                                                                   [ 04-20 15:00:45.477  3209: 3209 D/https://maps.googleapis.com/maps/api/place/nearbysearch/json?location=21.225225225225223&radLatLongUrl

更新了排队

我的更新代码如下所示。但它仍未正确生成URL。

        String Latitude = String.valueOf(mLastLocation.getLatitude());
                String Longitude = String.valueOf(mLastLocation.getLongitude());

   urlJsonObj = "https://maps.googleapis.com/maps/api/place/nearbysearch/json?location="+Latitude+","+Longitude+"&radius=500&type="+TypeName+"&key=AIzaSyBldIefF25dfjjtMZq1hjUxrj4T4hK66Mg";
                Log.d(urlJsonObj,"LatLongUrl");

Logcat中的

     [ 04-20 15:24:57.826 23415:23415 D/https://maps.googleapis.com/maps/api/place/nearbysearch/json?location=21.225225225225223,72.LatLongUrl

Answer 1

用此

替换你的行

 String urlJsonObj = 
 "https://maps.googleapis.com/maps/api/place/nearbysearch/json?location=" + 
 new BigDecimal(mLastLocation.getLatitude()).toString() + "," + 
 new BigDecimal(mLastLocation.getLongitude()).toString() + 
 "&radius=500&type=hospital&key=AIzaSyBldIefF25dfjjtMZq1hjUxrj4T4hK66Mg";

Answer 2

我认为在String.valueOf（mLastLocation.getLatitude（））和String.valueOf（mLastLocation.getLongitude（））之后你的括号缺少

String urlJsonObj = "https://maps.googleapis.com/maps/api/place/nearbysearch/json?location="+String.valueOf(mLastLocation.getLatitude())+","+String.valueOf(mLastLocation.getLongitude())+"&radius=500&type=hospital&key=AIzaSyBldIefF25dfjjtMZq1hjUxrj4T4hK66Mg";

那是你的日志

[04-20 15：00：45.477 3209：3209 D / https://maps.googleapis.com/maps/api/place/nearbysearch/json?location=21.225225225225223&radLatLongUrl

就像这样

Answer 3

 String latitude = String.valueOf(mLastLocation.getLatitude());
        String longitude = String.valueOf(mLastLocation.getLongitude())
        String urlJsonObj =String.format("https://maps.googleapis.com/maps/api/place/nearbysearch/json?" +
                "location=%s,%s &radius=500&type=hospital&key=AIzaSyBldIefF25dfjjtMZq1hjUxrj4T4hK66Mg",latitude,longitude);

这有助于您解决问题。

目前没有为lat和Long android生成动态网址
