在我的应用我显示的通知。 从服务我发送登录到JSON的时间。 它在服务器检查是否有任何新的数据可用与否，如果是，那么通过JSON我越来越没有新的数据，而最新数据的时间，我在显示它的通知。 如果我们点击通知其进入仪表板的活动页面，改变时序拉泰什数据的时间。 但问题是，当我点击通知后，首先进入仪表盘活动，则改变时间。 对于第2次点击通知后，这个原因是怎么回事了。 谁能告诉我如何在我的情况下，第一次点击后删除通知？ 这是我的条件调用一个新的通知码：
public class ReviewUpdateService extends IntentService{
private Notification.Builder earthquakeNotificationBuilder;
public static final int NOTIFICATION_ID = 1;
private String user_id;
JSONObject jsonData;
private static String share_pref_time_file = "time_file";
private static String share_pref_file = "json_file";
String service_notification;
int no_of_notify;
public ReviewUpdateService() {
super("ReviewUpdateService");
}
private AlarmManager alarmManager;
private PendingIntent alarmIntent;
public void onCreate() {
super.onCreate();
alarmManager = (AlarmManager)getSystemService(Context.ALARM_SERVICE);
SharedPreferences prefs = getSharedPreferences(share_pref_file,
Context.MODE_PRIVATE);
String strJson = prefs.getString("jsondata", "");
if (!strJson.equals("")) {
try {
jsonData = new JSONObject(strJson);
user_id = jsonData.getString(LoginActivity.KEY_UID);
} catch (JSONException e) {
e.printStackTrace();
}
}
String ALARM_ACTION = ReviewAlarmReceiver.ACTION_REFRESH_DASHBOARD_ALARM;
Intent intentToFire = new Intent(ALARM_ACTION);
alarmIntent = PendingIntent.getBroadcast(this, 0, intentToFire, 0);
earthquakeNotificationBuilder = new Notification.Builder(this);
earthquakeNotificationBuilder
.setAutoCancel(true)
.setTicker("New Review detected")
.setSmallIcon(R.drawable.icon_1);
}
public void refreshEarthquakes() {
// Get the XML
//URL url;
UserFunctions userFunctions = new UserFunctions();
SharedPreferences prefs = getSharedPreferences(share_pref_time_file,
Context.MODE_PRIVATE);
String formattedDate = prefs.getString("time", "");
try {
// Log.d("user_id", user_id);
// Log.d("time", formattedDate);
JSONObject json_city = userFunctions
.getNotification(user_id, formattedDate);
if(json_city!=null){
{
try {
String notify_get_id = json_city.getString(LoginActivity.KEY_NO_NOTIFY);
no_of_notify = Integer.parseInt(notify_get_id);
service_notification = json_city.getString(LoginActivity.KEY_SERVICE_NOTIFY);
} catch (JSONException e) {
e.printStackTrace();
}
}
if(no_of_notify > 0){
broadcastNotification(no_of_notify,"");
}
}
}
finally {
}
}
@Override
protected void onHandleIntent(Intent intent) {
int updateFreq = 1;
int alarmType = AlarmManager.ELAPSED_REALTIME_WAKEUP;
long timeToRefresh = SystemClock.elapsedRealtime() +
updateFreq*60*1000;
alarmManager.setInexactRepeating(alarmType, timeToRefresh, updateFreq*60*1000, alarmIntent);
refreshEarthquakes();
Intent broadcastIntent=new Intent();
broadcastIntent.setAction( ReviewAlarmReceiver.ACTION_REFRESH_DASHBOARD_ALARM );
sendBroadcast( broadcastIntent );
}
private void broadcastNotification(int no_of_review, String service_name) {
Intent startActivityIntent = new Intent(this, DashboardActivity.class);
startActivityIntent.putExtra("NotificationMessage", service_notification);
startActivityIntent.putExtra("flag", 1);
startActivityIntent.putExtra("notificationID", NOTIFICATION_ID);
startActivityIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
// startActivityIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK| Intent.FLAG_ACTIVITY_NEW_TASK );
PendingIntent launchIntent = PendingIntent.getActivity(this, 0,
startActivityIntent, PendingIntent.FLAG_UPDATE_CURRENT);
UserFunctions userFunctions = new UserFunctions();
if (userFunctions.isUserLoggedIn(getApplicationContext())) {
startActivityIntent.putExtra("latest_time", service_notification);
Log.d("latest_time", service_notification);
startActivityIntent.putExtra("flag", 1);
earthquakeNotificationBuilder
.setContentIntent(launchIntent)
.setContentTitle(no_of_review + " " + "new review is there")
.setAutoCancel(true);
// .setContentText(service_name);
if (no_of_review > 10) {
Uri ringURI = RingtoneManager
.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
earthquakeNotificationBuilder.setSound(ringURI);
}
double vibrateLength = 100 * Math.exp(0.53 * no_of_review);
long[] vibrate = new long[] { 100, 100, (long) vibrateLength };
earthquakeNotificationBuilder.setVibrate(vibrate);
int color;
if (no_of_review < 2)
color = Color.GREEN;
else if (no_of_review < 5)
color = Color.YELLOW;
else
color = Color.RED;
earthquakeNotificationBuilder.setLights(color, (int) vibrateLength,
(int) vibrateLength);
NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(NOTIFICATION_ID,
earthquakeNotificationBuilder.getNotification());
} else {
NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.cancelAll();
}
}
}
这就是我如何改变的请求JSON在仪表盘活动的时间：
protected void onNewIntent(Intent intent) {
DashboardActivity.this.finish();
// -----Start New Dashboard to notification clicked----
Intent i = new Intent(DashboardActivity.this, DashboardActivity.class);
Bundle extras = intent.getExtras();
if(extras != null){
startService(new Intent(this, ReviewUpdateService.class));
if(extras.containsKey("NotificationMessage"))
{
formattedDate= extras.getString("NotificationMessage");
}
if(extras.containsKey("flag"))
{
flag= extras.getInt("flag");
}
if(extras.containsKey("notificationID"))
{
NOTIFICATION_ID= extras.getInt("notificationID");
}
}
if(flag != 0){
NotificationManager nm = (NotificationManager)
getSystemService(NOTIFICATION_SERVICE);
nm.cancel(NOTIFICATION_ID);
SharedPreferences prefs1 = getSharedPreferences(
share_pref_time_file, Context.MODE_PRIVATE);
SharedPreferences.Editor editor = prefs1.edit();
editor.remove(share_pref_time_file);
editor.clear();
editor.commit();
getApplicationContext()
.getSharedPreferences(share_pref_time_file, 0).edit()
.clear().commit();
SharedPreferences prefs2 = getSharedPreferences(
share_pref_time_file, Context.MODE_PRIVATE);
SharedPreferences.Editor editor1 = prefs2.edit();
Log.d("latest_intent_time", formattedDate);
editor1.putString("time", formattedDate);
editor1.commit();
}
startActivity(i);
super.onNewIntent(intent);
}
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
NotificationManager nm = (NotificationManager)
getSystemService(NOTIFICATION_SERVICE);
nm.cancel(NOTIFICATION_ID);
setContentView(R.layout.dashboard);
startService(new Intent(this, ReviewUpdateService.class));
...................
}
}
