得到變量在doInBackground走出的AsyncTask

的如何獲得變量在doInBackground走出的AsyncTask得到變量在doInBackground走出的AsyncTask

請求API URL設置新的一樣，並得到新的像和像模式現在

如何獲得新的像和像模式出來的AsyncTask的使用的setText

得到這樣從GetDataLike的AsyncTask：

  new GetDataLike().execute(textViewQuoteId.getText().toString()); 
      String newLike = GetDataLike().newLike; // get like this from GetDataLike 
      String modeLike = GetDataLike().modeLike; // get like this from GetDataLike 
      textViewQuoteLike.setText("پسندیدم ("+newLike+")"); 
      Toast.makeText(rootView.getContext(), "لایک شما برای سخن "+textViewProfileName.getText().toString()+" ثبت شد.", 
        Toast.LENGTH_LONG).show();

JSON結果例如：

{"Like":{"quote_like":"27","quote_like_mode":"1"}}

你應該看看如何異步任務工作，要做到這一點在你的onPostExcecute您的AsyncTask，而不是在同步方式如你所說 – Thomas

怎麼做而不做的AsyncTask，請例如請求API，並獲得新的像數和模式就像沒有的AsyncTask如果AsynsTask是問題 – user8215914

的AsyncTask是使用最好的東西，你只是用它錯了。正如我所說的，這將有助於如果您想了解asynctasks一些文檔和示例。在這種情況下，你應該使用'onPostExecute'中的AsyncTask的 – Thomas

你就必須從doInBackground方法和onPostExecute方法，你可以setText.for多個值這是在你的情況，你應該做這樣的

返回字符串

public class CollectValues{ 
public String quote_like; 
public String quote_like_mode;}

現在在doInBackground方法，你應該做這樣的

CollectValue cv = new CollectValue(); 
    cv.quote_like=//your response; 
    cv.quote_like=//your response; 
      return cv;

終於在onPostExecute方法，你應該做這樣的

@Override 
    protected void onPostExecute(CollectValues cv) { 
     //your textview here 
     textview1.setText(cv.quote_like); 
     textview2.setText(cv.quote_like_mode); 
    }

這將解決你的問題..

謝謝，我想出來的AsyncTask – user8215914

基本上你onPostExecute方法將在UI線程so..i無法理解你到底想要什麼跑？你'onPostExecute需要（）''要和SharedPreferences'在你需要它retreive它 –

保存價值。 – Stanojkovic
