Question

我希望通过调用服务器上的webservice的URL链接将userdata插入数据库：例如：这是链接：

http://mydomain.com/AndroidWebService.asmx/nInsertInfo?id=12&lat=23.2222&log=12322

所以我想以隐藏模式调用此URL。

Answer 1

使用android android AsyncTask发布数据。它在应用程序打开时在android后台工作。 AsyncTask可以正确，方便地使用UI线程。该类允许执行后台操作并在UI线程上发布结果，而无需操纵线程和/或处理程序。

感谢。

Answer 2

感谢所有宝贵的解决方案。

我是通过创建WebView

来做到的

WebView myWebView = (WebView) findViewById(R.id.view1);
myWebView.loadUrl(urll);

然后我可以根据需要管理我的WebView：隐藏它，对齐为错误或结果返回。

也许这个例子可以帮到你：

public class URLConnectionTask <Result> extends AsyncTask<URL, Void, InputStream> {


        @Override
        protected InputStream doInBackground(URL... params) {
            InputStream is;
            HttpUriRequest request;
            URI uri;
            HttpResponse response;

            if (params.length == 0)
                return null;

            is = null;CredentialsProvider credProvider = new BasicCredentialsProvider();

        if (userName != null && userName.length() > 0 && password != null && password.length() > 0)
            credProvider.setCredentials(new AuthScope(AuthScope.ANY_HOST, AuthScope.ANY_PORT),
                new UsernamePasswordCredentials(userName, password));

        //
        DefaultHttpClient http = new DefaultHttpClient();
        http.setCredentialsProvider(credProvider);
        //

        uri = URI.create(params[0].toString());

        if (isPost)
            request = new HttpPost(uri);
        else
            request = new HttpGet(uri);

        try {           
            response = http.execute(request);
            is = response.getEntity().getContent();

            //Log.d(TAG, "doInBackground() response: "+EntityUtils.toString(response.getEntity()));
        } catch (ClientProtocolException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }


       if (processingHandler != null && is != null)
           processingResult = processingHandler.processResponse(is);// processingHandler is an instance which implements ProcessingHandler interface (ex. VizMarket). processResponse() is implemented on this class.

       return is;
    }

    @Override
        protected void onPostExecute (InputStream result) {
            input = result;

            if (result == null)
                return;
                    //instruction for inserting data on db .... 

            try {
                result.close();
            } catch (IOException e) {
            }
        }
    }

Answer 4

您应该在AsyncTask中调用URL。例如：Return data from AsyncTask class

Answer 5

你必须使用一个线程从服务器获取数据并插入到DB或在android中你可以使用AsyncTask。

Answer 6

您可以进行搜索：ClickableSpan 并将您的插入代码放入OnClick主体〜就像：

String yourTextStr;
    SpannableString sp = new SpannableString(yourTextStr);
    int start;//the start of your url in the text; 
    int end ;//the end of your url in the text; 
    sp.setSpan(new ClickableSpan() {
        @Override
        public void onClick(View widget) {
            //Your Insert Code
        }
    }, start, end, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
