Question

来自FirstActivity我正在创建三个单独的Notifications并在单击它们时启动SecondActivity，它位于同一个应用程序中。问题是SecondActivity中字符串的值始终是我发布的最后一个通知。我需要启动SecondActivity并显示调用来自通知1，当我点击ID为1的通知时，类似地对于id = 2和id = 3。但我失去那些在我的意图对象中加入额外内容的东西。如果您以前遇到过这种情况，请帮助我。我已经尝试了PendingIntent标志FLAG_CANCEL_CURRENT但是徒劳无功。提前致谢。： - ）

NotificationManager nm;
Notification n;
PendingIntent pi1, pi2, pi3;
Button btnNotify1, btnNotify2, btnNotify3;
Intent intent;

final static String TICKER_TEXT = "My_Notification";

@Override
protected void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_notification);

    btnNotify1 = (Button) findViewById(R.id.btnNotify1);
    btnNotify2 = (Button) findViewById(R.id.btnNotify2);
    btnNotify3 = (Button) findViewById(R.id.btnNotify3);

    nm = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);

    n = new Notification(R.drawable.ic_launcher, TICKER_TEXT,
        System.currentTimeMillis());
    n.flags = n.flags | Notification.FLAG_AUTO_CANCEL;

    intent = new Intent(this, SecondActivity.class);
    intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);

    btnNotify1.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {

            intent.putExtra("call_is_from", "Notification 1");
            pi1 = PendingIntent.getActivity(getApplicationContext(), 0,
                intent, PendingIntent.FLAG_UPDATE_CURRENT);
            n.setLatestEventInfo(getApplicationContext(), "Notification 1",
                "One", pi1);
            nm.notify(1, n);

        }
    });
    btnNotify2.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {

            intent.putExtra("call_is_from", "Notification 2");
            pi2 = PendingIntent.getActivity(getApplicationContext(), 0,
                intent, PendingIntent.FLAG_UPDATE_CURRENT);
            n.setLatestEventInfo(getApplicationContext(), "Notification 2",
                "Two", pi2);
            nm.notify(2, n);

        }
    });
    btnNotify3.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {

            intent.putExtra("call_is_from", "Notification 3");
            pi3 = PendingIntent.getActivity(getApplicationContext(), 0,
                intent, PendingIntent.FLAG_UPDATE_CURRENT);
            n.setLatestEventInfo(getApplicationContext(), "Notification 3",
                "Three", pi3);
            nm.notify(3, n);

        }
    });
}

您需要确保每个PendingIntent都是唯一的。由于您使用相同的PendingIntent和相同的Intent获得requestCode，因此您将始终获得相同的PendingIntent（即使附加内容不同）。

要确保您的每个PendingIntent都是唯一的，请为每个requestCode使用不同的pi1 = PendingIntent.getActivity(getApplicationContext(), 1, intent, PendingIntent.FLAG_UPDATE_CURRENT); pi2 = PendingIntent.getActivity(getApplicationContext(), 2, intent, PendingIntent.FLAG_UPDATE_CURRENT); pi3 = PendingIntent.getActivity(getApplicationContext(), 3, intent, PendingIntent.FLAG_UPDATE_CURRENT);，如下所示：
