增加Serie

Question

我有一个按钮列表，我希望每个发布一个加载发布元素的唯一预加载。问题是第一个完成200ms的运行，第二个在3秒，第三个永远不会停止加载。 ..异步不完全结束。我不知道是否存在胎面平行度问题。无论如何使用休息控制台一切都很完美。

public class URLDataReader extends AsyncTask<URL, String, String> {

    Context mContext;
    OnAsyncTaskComplete listener;

    public URLDataReader(Context context, OnAsyncTaskComplete lisener) {
        mContext = context;
        listener = lisener;
    }

    @Override
    protected String doInBackground(URL... data) {


        HttpClient httpclient = new DefaultHttpClient();
        HttpPost httppost = new HttpPost(data[0].toString());
        HttpResponse response = null;

        try {

            List<NameValuePair> nameValuePairs = Globals.postUrl();
            httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
            //SETTA I POST IN GLOBALS

            //nameValuePairs.add(new BasicNameValuePair("username", "s.alberti"));
            //nameValuePairs.add(new BasicNameValuePair("password", "65.VALE.61"));
            //execute http post
            response = httpclient.execute(httppost);


        } catch (Exception e) {
            Toast.makeText(mContext, e.getMessage(), Toast.LENGTH_LONG).show();
        }

        try {
            return convertHttpResponseToString(response);
        } catch (IOException e) {
            e.printStackTrace();
        }

        return null;
    }

    @Override
    protected void onPostExecute(String s) {
        super.onPostExecute(s);
        listener.OnAsyncTaskComplete(s);
    }


    private String convertHttpResponseToString(HttpResponse response) throws IOException {
        InputStream responseStream = response.getEntity().getContent();
        Scanner scanner = new Scanner(responseStream, "UTF-8");
        String responseString = scanner.useDelimiter("\\Z").next();
        scanner.close();
        return responseString;
    }
}

    enter code here

GLOBAL

   public static List<NameValuePair> postUrl(){
        List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(1);
        nameValuePairs.add(new BasicNameValuePair("username", "s.alberti"));
        nameValuePairs.add(new BasicNameValuePair("password", "Vale6165"));
        return nameValuePairs;
    }
