AsyncTaskでタイムアウト機能を設定する[Android]

Question

私の場合は、ボタンを押してタイムアウトの処理を取得したいと思います。ボタンをクリックすると、検証（ProgressDialog）が5秒を超えると、WebサービスでaccNoを確認し、alertDialogを停止して表示して、ユーザーのタイムアウトを確認します。

しかし、今は1ミリ秒でテストしたときに、論理的にはalertDialogで一時停止して押し込まれるまではわかりませんが、今度はダイアログをミリ秒単位で表示して自動的に閉じて次の動作を行うようになります。私のコードは次のとおりです。

@Override 
protected void onCreate(final Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_information3); 

btn_next.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View v) { 
      if (title.getText().toString().equals("INFO")) { 
       InfoAsyncTask infoAsyncTask = new InfoAsyncTask(); 
       try { 
        infoAsyncTask.execute().get(1, TimeUnit.MILLISECONDS); 
       } catch (InterruptedException e) { 
        e.printStackTrace(); 
       } catch (ExecutionException e) { 
        e.printStackTrace(); 
       } catch (TimeoutException e) { 
        AlertDialog.Builder alertDialog = new AlertDialog.Builder(Information3.this); 
        alertDialog.setTitle(":: Error ::"); 
        alertDialog.setMessage("Verify Timeout. Please try again."); 

        alertDialog.setPositiveButton(android.R.string.yes, new DialogInterface.OnClickListener() { 
         @Override 
         public void onClick(DialogInterface dialog, int which) { 
          dialog.dismiss(); 
         } 
        }); 
        alertDialog.show(); 
       } 
      } 
     }); 
    } 

private class InfoAsyncTask extends AsyncTask<Void, Void, String> { 
    private String results; 
    private ProgressDialog pDialog; 
    private Object resultRequestSOAP; 
    String accNo = et_accNo.getText().toString().trim(); 
    int timeout = 15000; 

    @Override 
    protected void onPreExecute() { 
     pDialog = new ProgressDialog(Information3.this); 
     pDialog.setMessage("Verifying..."); 
     pDialog.setIndeterminate(false); 
     pDialog.setCancelable(true); 
     pDialog.show(); 
     super.onPreExecute(); 
    } 

    @Override 
    protected String doInBackground(Void... params) { 
     SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME); 
     request.addProperty("Code", InfoCode); 
     request.addProperty("AccNo", accNo); 

     SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11); 
     envelope.dotNet = true; 
     envelope.setOutputSoapObject(request); 
     HttpTransportSE androidHttpTransport = new HttpTransportSE(URL, timeout); 
     androidHttpTransport.debug = true; 

     try { 
      androidHttpTransport.call(SOAP_ACTION, envelope); 
      String requestDumpString = androidHttpTransport.requestDump; 
      Log.d("request Dump: ", requestDumpString); 
     } catch (Exception e) { 
      e.printStackTrace(); 
     } 
     try { 
      resultRequestSOAP = envelope.getResponse(); 
      results = resultRequestSOAP.toString(); 
      Log.d("Output: ", results); 
     } catch (Exception e) { 
      e.printStackTrace(); 
     } 
     return null; 
    } 

    protected void onPostExecute(String result) { 
     if (resultRequestSOAP == null) { 
      if (pDialog.isShowing()) { 
       pDialog.dismiss(); 
      } else { 
       AlertDialog.Builder alertDialog = new AlertDialog.Builder(Information3.this); 

       alertDialog.setTitle(":: Error ::"); 
       alertDialog.setMessage("Connection error, please check your internet connection."); 

       alertDialog.setPositiveButton(android.R.string.yes, new DialogInterface.OnClickListener() { 
        @Override 
        public void onClick(DialogInterface dialog, int which) { 
         dialog.dismiss(); 
        } 
       }); 
       alertDialog.show(); 
       pDialog.dismiss(); 
      } 
     } else { 
      if (results.equals("false")) { 
       AlertDialog.Builder alertDialog = new AlertDialog.Builder(Information3.this); 

       alertDialog.setTitle(":: Warning ::"); 
       alertDialog.setMessage("Please fill in correct account number"); 

       alertDialog.setPositiveButton(android.R.string.yes, new DialogInterface.OnClickListener() { 
        @Override 
        public void onClick(DialogInterface dialog, int which) { 
         dialog.dismiss(); 
        }

       alertDialog.show(); 
      } else if (et_billNo.getText().toString().trim().isEmpty()) {

       alertDialog.setTitle(":: Warning ::"); 
       alertDialog.setMessage("Please fill in bill number"); 

       alertDialog.setPositiveButton(android.R.string.yes, new DialogInterface.OnClickListener() {

        } 
       }); 
       alertDialog.show(); 
      } else if (et_amountNo.getText().toString().trim().isEmpty() || Integer.parseInt(et_amountNo.getText().toString().trim()) <= 0) { 
       AlertDialog.Builder alertDialog = new AlertDialog.Builder(Information3.this); 

       alertDialog.setTitle(":: Warning ::"); 
       alertDialog.setMessage("Please fill in amount"); 

       alertDialog.setPositiveButton(android.R.string.yes, new DialogInterface.OnClickListener() { 
        @Override 
        public void onClick(DialogInterface dialog, int which) {

        } 
       }); 
       alertDialog.show(); 
      } else if (results.equals("true")) { 
       Title = title.getText().toString(); 
       String value1 = et_accNo.getText().toString().trim(); 
       String value2 = et_billNo.getText().toString().trim(); 
       int value3 = Integer.parseInt(et_amountNo.getText().toString().trim()); 

       addSearchInput(value1); 
       addSearchInput(value2); 
       addSearchInput(String.valueOf(value3)); 

       Intent intent = new Intent(Information3.this, confirmation3.class);

Answer 1

get（）メソッドはUIスレッドをブロックし、私はあなたがこれを望まないと思います。

あなたは

final Handler handler = new Handler(); 
    handler.postDelayed(new Runnable() { 
     @Override 
     public void run() { 
     AsyncTask.cancel(); 
     } 
    }, 1); 

がAsyncTaskを持つ多くの落とし穴があるので注意してください）（https://developer.android.com/reference/android/os/Handler.html#postDelayed(java.lang.Runnable、ロング）[そのように]タイムアウトによりdoInBackgroundでメカニックをキャンセルして（）AsyncTask.cancelを呼び出して実装する必要があり、私のarticleを確認してください。
