Android Java : URL에서 콘텐츠 가져 오기

Question

Android 앱을 사용하여 만든 웹 사이트의 콘텐츠를 가져 오려고합니다. 번역기 앱은 URL 변수를 기반으로 문자열을 반환합니다.

그러나 URL을 가져올 때마다 기대되는 번역 된 문자열 대신 com.example.reviantranslator.RetrieveFeedTask@b1eed738이 변형됩니다. .

어디로 잘못 가고 있습니까?

public class MainActivity extends ActionBarActivity { 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 

     final EditText et = (EditText) findViewById(R.id.editText1); 
     final EditText et2 = (EditText) findViewById(R.id.editText2); 

     final Button button = (Button) findViewById(R.id.button1); 
     button.setOnClickListener(new View.OnClickListener() { 
      public void onClick(View v) { 
       //Toast.makeText(getBaseContext(), "click", Toast.LENGTH_LONG).show(); 
       String english = et.getText().toString(); 
       String revian = et2.getText().toString(); 
       if (!english.isEmpty() && revian.isEmpty()) { 
        String[] words = english.split(" "); 
        for (int i = 0; i < words.length; i++) { 
         try { 
          revian = revian + queryDB(words[i], false); 
         } catch (IOException e) { 
          // TODO Auto-generated catch block 
          e.printStackTrace(); 
         } 
        } 
        et2.setText(revian); 
       } 
      } 
     }); 
    } 



    @Override 
    public boolean onCreateOptionsMenu(Menu menu) { 
     // Inflate the menu; this adds items to the action bar if it is present. 
     getMenuInflater().inflate(R.menu.main, menu); 
     return true; 
    } 

    @Override 
    public boolean onOptionsItemSelected(MenuItem item) { 
     // Handle action bar item clicks here. The action bar will 
     // automatically handle clicks on the Home/Up button, so long 
     // as you specify a parent activity in AndroidManifest.xml. 
     int id = item.getItemId(); 
     if (id == R.id.action_settings) { 
      return true; 
     } 
     return super.onOptionsItemSelected(item); 
    } 

    public String queryDB(String word, boolean revian) throws IOException { 
     String variab = "le"; 
     if (revian) { 
      variab = "lr"; 
     } 
     String fullurl = "http://maereti.com/p/Revian/revian.php?"+variab+"="+word; 

     RetrieveFeedTask RTF = new RetrieveFeedTask(); 

     AsyncTask<String, String, String> out = RTF.execute(fullurl); 

     String output = out.toString(); 

     return output; 

    } 

    public void ToastThis(String words) { 
     Toast.makeText(getBaseContext(), "toast function "+words, Toast.LENGTH_LONG).show(); 
    } 




} 

그리고 RetrieveFeedTask 클래스 :

public class RetrieveFeedTask extends AsyncTask<String, String, String> { 

    URL url; 

    @Override 
    protected String doInBackground(String... urls) { 
     String outputLine = ""; 
     Looper.prepare(); 
     MainActivity MA = new MainActivity(); 

     try { 
      URL url = new URL(urls[0]);  
      BufferedReader in = new BufferedReader(new InputStreamReader(url.openStream())); 

      String inputLine; 

      while ((inputLine = in.readLine()) != null) { 
       outputLine = outputLine + inputLine; 
      } 


      MA.ToastThis(outputLine); 

      in.close(); 

      return outputLine; 

     } catch (Exception e) { 
      e.printStackTrace(); 
      return "!! I am error !!"; 
     } 




    } 

    protected void onPostExecute(String feed) { 
     // TODO: check this.exception 
     // TODO: do something with the feed 
    } 

} 

Answer 1

당신은 당신의 AsyncTask에서 결과를 검색하지만, 단지 문자열로 작업 자체를 변환 아닙니다. 당신은 그것을 못을 박았다

AsyncTask<String, String, String> out = RTF.execute(fullurl); 

String output = out.get();
