public void setReminder( int year,int month,int day,int hour,int minite)
   {


           notificationCount  = notificationCount+1;
           String[] parts = mEditTextDate.getText().toString().trim().split("/");

   }


  }

ReminderAlarm.java

  public class ReminderAlarm  extends BroadcastReceiver{

   private Notification notification;   

   @Override

      mNotificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
      CharSequence from = intent.getStringExtra("Name");
      CharSequence message = intent.getStringExtra("Description");
      Intent notificationIntent1 = new Intent(context, NotificationView.class);
      notificationIntent1.putExtra("Name", from);
      notificationIntent1.putExtra("Description", message);
      notificationIntent1.putExtra("NotifyCount", intent.getExtras().get("NotifyCount").toString());

      PendingIntent contentIntent = PendingIntent.getActivity(context, 0,notificationIntent1, 0);
      RemoteViews expandedView = new RemoteViews(context.getPackageName(), R.layout.notification_layout);
        expandedView.setTextViewText(R.id.noti_first, from);
        expandedView.setTextViewText(R.id.noti_second, message);

        Notification notification = new NotificationCompat.Builder(context)
                .setSmallIcon(R.drawable.app_logo)
                .setAutoCancel(true)
                .setContentIntent(contentIntent)
                .setContentTitle(from).setContentText(message).build();
      notification.defaults |= Notification.DEFAULT_SOUND;
      mNotificationManager.notify(Integer.parseInt(intent.getExtras().get("NotifyCount").toString()), notification);        
      Toast.makeText(context, "New Notification Received",  Toast.LENGTH_SHORT).show(); 

   }
 }

NotificationView.java

public class NotificationView extends Activity  {
String title;
String text;
TextView txttitle;
TextView txttext;
String noti;
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.notificationview);
        Intent i = getIntent();

        title = i.getStringExtra("Name");
        text = i.getStringExtra("Description");
        noti =i.getStringExtra("NotifyCount");
        System.out.println("title "+title);
        System.out.println("text "+text);
        System.out.println("noti "+noti);
        // Locate the TextView
        txttitle = (TextView) findViewById(R.id.title);
        txttext = (TextView) findViewById(R.id.text);

        txttitle.setText("Title : "+title);
        txttext.setText(Html.fromHtml("<b> Description :</b>"+" "+text) );

}


}

当我运行上面的代码第一个通知在我的 Notificationview.java class 中显示正确但是当我发出第二个通知并点击它会显示我发出的第一个通知，它不会在 notificationview.java class 中更新通知显示 class 知道我该如何解决它吗？

Answer 1

在您的 NotificationView 中实现覆盖方法 class。

/**
 * Method to decide which detail view should be called on the basis of
 * notification when notification is clicked.
 * @param intent
 */
public void onNewIntent(Intent intent) {

    try {
        Bundle extras = intent.getExtras();
        if (extras != null) {
             title = intent.getStringExtra("Name");
             text = intent.getStringExtra("Description");
             noti = intent.getStringExtra("NotifyCount");

    // Locate the TextView
    txttitle = (TextView) findViewById(R.id.title);
    txttext = (TextView) findViewById(R.id.text);

    txttitle.setText("Title : "+title);
    txttext.setText(Html.fromHtml("<b> Description :</b>"+" "+text) );
        }
    } catch (Exception e) {
        e.printStackTrace();
    }
}

在您的 onCreate 方法中，调用 onNewIntent(getActivity().getIntent());

希望它有效。
