Answer 1

먼저

<uses-permission android:name="android.permission.INTERNET"/> 

그런 다음 비동기 작업의 doinbackground 방법에 중 모든 네트워킹 코드를 삽입 스레드 또는에 명시하려면 다음 코드를 추가하십시오.

이렇게하면 문제가 해결됩니다.

당신은

new loadstuff.execute("url"); 

public class loadSomeStuff extends AsyncTask<String, Integer, String>{ 

    String result=null; 

    @Override 
    protected String doInBackground(String... params) { 
     // TODO Auto-generated method stub 
     //proberen met internet te connecten 
     try{ 
      //maak nieuw client object 
      HttpClient httpclient = new DefaultHttpClient(); 

      //post to onze url, site is voorbeeld 
      HttpPost httppost = new HttpPost("http://ephemeraltech.com/demo/android_tutorial20.php"); 

      //voor post uit en get response 
      HttpResponse response = httpclient.execute(httppost); 

      //get message from response 
      HttpEntity entity = response.getEntity(); 

      //get content van message 
      InputStream webs = entity.getContent(); 

      //nu hebben we response, convert to string 

      try 
      { 
       BufferedReader reader = new BufferedReader(new InputStreamReader(webs, "iso-8859-1"), 8); 

       //text view removed from here 
       result=reader.readline(); 

       //sluiten 
       webs.close(); 

      }catch(Exception e){ 
       Log.e("log_tag", "Error converting result "+e.toString()); 
      } 
     }catch(Exception e){ 
      Log.e("log_tag", "Error in http connection "+e.toString()); 
     } 
return null; 
} 

onPostExecute(){ 

      //declare your text view here & assign result to your text view. 
      myTextView.setText(result); 

    } 
}
