我是否需要用户的许可INTERNET？以及如何实现这个？

Answer 1

对于android中的任何网络通信，你必须在Manifest文件中声明INTERNET权限，而且所有网络通信都应该在一个单独的线程上完成（使用Async Task），否则会引发运行时异常。

Answer 2

public class AsyncTaskExample extends AsyncTask<String, Void, Boolean>{
    private ProgressDialog progressDialog;
    private Activity activity;

    public AsyncTaskExample(Activity activity, ProgressDialog progress) {
        activity = activity;
        progressDialog = progress;
    }

    @Override
    protected void onPreExecute(){
        progressDialog.show();
    }   

    @Override
    protected Boolean doInBackground(String... params) {
//params is array of strings containing values which are passing while calling this AsyncTaskExample 
          int responseCode;
          String responseString;
          List<BasicNameValuePair> nameValuePairs = null;
          HttpParams httpParameters = new BasicHttpParams();
        // Set the timeout in milliseconds until a connection is established.
        int timeoutConnection = 20000;
        HttpConnectionParams.setConnectionTimeout(httpParameters, timeoutConnection);
        // Set the default socket timeout (SO_TIMEOUT) 
        // in milliseconds which is the timeout for waiting for data.
        int timeoutSocket = 20000;
        HttpConnectionParams.setSoTimeout(httpParameters, timeoutSocket);

        HttpClient httpclient = new DefaultHttpClient(httpParameters);

        HttpPost httpPost = new HttpPost("YOUR_URL");
        HttpResponse response;
        nameValuePairs = new ArrayList<BasicNameValuePair>();
            nameValuePairs.add(new BasicNameValuePair("user", varTwo ));
            nameValuePairs.add(new BasicNameValuePair("password", varThree ));
            httpPost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
            response = httpclient.execute(httpPost);
            responseCode = response.getStatusLine().getStatusCode();
            responseString = EntityUtils.toString(response.getEntity());

          return isSuccess; 
  }

    @Override
    protected void onPostExecute(Boolean isSuccess){ 
        try {
            progressDialog.dismiss();
        } catch (Exception e) {
            Log.e(TAG, "Error while closing dialog");
        }

    }

在代码中的某个位置调用异步任务示例，例如

AsyncTaskExample loginTask =  new AsyncTaskExample (this, progressDialog);
            task.execute(userName, password); 
// here userName, password are the params which should paass to your webservice, it will get in doInBackGroung by params variable as params[0], params[1]

you should also have internet permission in manifest file

如何在我的应用程序中使用httpget
