      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();

      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时，第一个通知在我的 Notificationview.java 类中显示正确，但是当我发出第二个通知并单击它时，它将显示我发出的第一个通知，它不会更新通知显示在 notificationview.java 类中，我该如何解决它？

Answer 1

在您的 NotificationView 类中实现覆盖方法。

/**
 * 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());

希望它有用。
