我有这段代码，我想要两个不同的动作，我想显示一个经典通知来打开 MainActivity，另一个通知来做 LogoutTask，但是我有这个 java.lang.RuntimeException: Can't create handler inside thread没有调用 Looper.prepare()
我向您展示了我的 NotificationBuilder、AsyncTask 和错误。
通知方式
private void sendNotification(final String message) { if (!message.contains("password")) { Intent intent = new Intent(this, MainActivity.class); intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); PendingIntent pendingIntent = PendingIntent.getActivity(this, 0 /* Request code */, intent, PendingIntent.FLAG_UPDATE_CURRENT); Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION); NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this) .setSmallIcon(R.drawable.ic_stat_kleim_letter) .setContentTitle(TITLE_NAME) .setContentText(message) .setAutoCancel(true) .setSound(defaultSoundUri) .setContentIntent(pendingIntent); NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE); Random random = new Random(); int m = random.nextInt(9999 - 1000) + 1000; notificationManager.notify(m, notificationBuilder.build()); } else { DoLogoutTask doLogoutTask = new DoLogoutTask(getBaseContext()); doLogoutTask.execute(); Intent intent = new Intent(MyGcmListenerService.this, Login.class); intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); PendingIntent pendingIntent = PendingIntent.getActivity(MyGcmListenerService.this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT); Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION); NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(MyGcmListenerService.this) .setSmallIcon(R.drawable.ic_stat_kleim_letter) .setContentTitle(TITLE_NAME) .setContentText(message) .setAutoCancel(true) .setSound(defaultSoundUri) .setContentIntent(pendingIntent); NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE); notificationManager.notify(0, notificationBuilder.build()); } }
异步任务
public class DoLogoutTask extends AsyncTask<Void, Void, Boolean> { SoapPrimitive resultString; String response; SharedPreferences mSharedPreferences; SharedPreferences.Editor editor; Context context; ProgressDialog progressDialog; public DoLogoutTask(Context context) { this.context = context; this.progressDialog = new ProgressDialog(context, R.style.progress_dialog_kleim); } @Override protected void onPreExecute() { this.progressDialog.show(); this.progressDialog.setProgressStyle(android.R.style.Widget_ProgressBar_Small); this.progressDialog.setCancelable(false); this.progressDialog.getWindow().setGravity(Gravity.BOTTOM); this.progressDialog.setIndeterminate(true); } @Override protected Boolean doInBackground(Void... params) { return doLogout(); } @Override protected void onPostExecute(Boolean result) { if (progressDialog != null && progressDialog.isShowing()) progressDialog.dismiss(); } public Boolean doLogout() { Boolean isLoggedOut = null; mSharedPreferences = context.getSharedPreferences(PreferencesUtility.MYPREFERENCES, Context.MODE_PRIVATE); String URL = URL; String METHOD = METHOD; String NAMESPACE = NAMESPACE; String SOAP_ACTION = ACTION; String idCliente = mSharedPreferences.getString(PreferencesUtility.IDCLIENTE, PreferencesUtility.VALUENOTFOUND); String regid = mSharedPreferences.getString(PreferencesUtility.REGID, PreferencesUtility.VALUENOTFOUND); JSONObject parent = new JSONObject(); JSONObject logout = new JSONObject(); JSONArray jsonArray = new JSONArray(); try { logout.put("idCliente", idCliente); logout.put("regid", regid); parent.put("cliente", jsonArray); jsonArray.put(logout); String parentString = parent.toString(); PropertyInfo paramPI = new PropertyInfo(); paramPI.setName("infoCliente"); paramPI.setValue(parentString); paramPI.setType(String.class); SoapObject request = new SoapObject(NAMESPACE, METHOD); request.addProperty(paramPI); SoapSerializationEnvelope soapSerializationEnvelope = new SoapSerializationEnvelope(SoapEnvelope.VER11); soapSerializationEnvelope.dotNet = true; soapSerializationEnvelope.setOutputSoapObject(request); HttpTransportSE transportSE = new HttpTransportSE(URL); transportSE.call(SOAP_ACTION, soapSerializationEnvelope); resultString = (SoapPrimitive) soapSerializationEnvelope.getResponse(); response = resultString.toString(); isLoggedOut = !response.contains("error"); } catch (JSONException e) { e.printStackTrace(); } catch (HttpResponseException e) { e.printStackTrace(); } catch (SoapFault soapFault) { soapFault.printStackTrace(); } catch (XmlPullParserException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } catch (Exception e) { e.printStackTrace(); } return isLoggedOut; } }
