Etwas falsch: readerActivity.SendPostRequest kann nicht in Context

Question

im umgewandelt werden versuchen, Daten zu senden, und nachdem ich es bekommen, im Versuch, eine elemenet zu schaffen, aber es gibt Fehler wie:

Fehler: (121, 48) Fehler: inkompatible Typen: readerActivity.SendPostRequest kann nicht auf Context

aber ohne sich diese Daten von der Website umgewandelt werden - funktioniert gut

public class SendPostRequest extends AsyncTask<String, Void, String> { 

    protected void onPreExecute(){} 

    protected String doInBackground(String... arg0) { 

     try { 

      String book = getIntent().getExtras().getString("book"); 
      String page = "2"; 

      URL url = new URL("http://website.org/test"); // here is your URL path 

      JSONObject postDataParams = new JSONObject(); 
      postDataParams.put("one", book); 
      postDataParams.put("two", page); 
      Log.e("params",postDataParams.toString()); 

      HttpURLConnection conn = (HttpURLConnection) url.openConnection(); 
      conn.setReadTimeout(15000 /* milliseconds */); 
      conn.setConnectTimeout(15000 /* milliseconds */); 
      conn.setRequestMethod("POST"); 
      conn.setDoInput(true); 
      conn.setDoOutput(true); 

      OutputStream os = conn.getOutputStream(); 
      BufferedWriter writer = new BufferedWriter(
        new OutputStreamWriter(os, "UTF-8")); 
      writer.write(getPostDataString(postDataParams)); 

      writer.flush(); 
      writer.close(); 
      os.close(); 

      int responseCode=conn.getResponseCode(); 

      if (responseCode == HttpsURLConnection.HTTP_OK) { 

       BufferedReader in=new BufferedReader(new 
         InputStreamReader(
         conn.getInputStream())); 

       StringBuffer sb = new StringBuffer(""); 
       String line=""; 

       while((line = in.readLine()) != null) { 

        sb.append(line); 
        break; 
       } 

       in.close(); 
       return sb.toString(); 

      } 
      else { 
       return new String("false : "+responseCode); 
      } 
     } 
     catch(Exception e){ 
      return new String("Exception: " + e.getMessage()); 
     } 

    } 

    @Override 
    protected void onPostExecute(String result) { 

     LinearLayout llMain = (LinearLayout) findViewById(R.id.activity_reader); 

     String text = result; 
     String[] parts = text.split("</br></br>"); 
     for (String part : parts) 
     { 
      FlowLayout ab = new FlowLayout(this); 
      llMain.addView(ab); 
      ab.setPadding(1,1,1,35); 
      FlowLayout fab = new FlowLayout(this); 
      ab.addView(fab); 

      String[] words = part.split(" "); 
      for (String word : words) 
      { 
       TextView btnNew = new TextView(this); 
       btnNew.setText(word.toString()); 
       ab.addView(btnNew); 
       btnNew.setPadding(20,15,20,25); 
       btnNew.setTextSize(19); 
      } 

     } 

    } 
} 

public String getPostDataString(JSONObject params) throws Exception { 

    StringBuilder result = new StringBuilder(); 
    boolean first = true; 

    Iterator<String> itr = params.keys(); 

    while(itr.hasNext()){ 

     String key= itr.next(); 
     Object value = params.get(key); 

     if (first) 
      first = false; 
     else 
      result.append("&"); 

     result.append(URLEncoder.encode(key, "UTF-8")); 
     result.append("="); 
     result.append(URLEncoder.encode(value.toString(), "UTF-8")); 

    } 
    return result.toString(); 
} 

Answer 1

ihre getan, ich

gerade geändert

FlowLayout ab = new FlowLayout(this); 

zu

FlowLayout ab = new FlowLayout(getApplicationContext()); 

und es funktioniert gut
