Question

我正在为我的学校编写一个Android应用程序，我对通知有一点问题：我的应用程序检查主页是否在后台更新（页面日期比最后一个日期的日期更新）。如果页面已更新，应用程序会构建一个通知（直到这里工作正常）有2个选项：Dismiss或show（也有效）。 “显示”工作正常，但我的问题是“解雇”，因为它必须更新设置中的日期，然后它应该退出，但它总是显示最后打开的活动。

我正在使用Intent extras管理它的Activity：

public class ***********Handler extends Activity {

        String EXTRA_ACTION = "de.xorg.*****.ACTION";
        String EXTRA_VPDATE = "de.xorg.*****.VPDATE";

  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.ntd);

    Intent intent = getIntent();
    String todo = intent.getStringExtra(EXTRA_ACTION);  //Action from Notification ("D" or "S")
    String date = intent.getStringExtra(EXTRA_VPDATE);  //New date
    if(todo.toLowerCase().contains("d")) {     
        //update date value
        Editor editor = PreferenceManager.getDefaultSharedPreferences(this).edit();
        editor.putString("readDate", date);
        editor.commit();

        // Remove notification
        NotificationManager notificationManager = (NotificationManager)  this.getSystemService(Context.NOTIFICATION_SERVICE);
        notificationManager.cancel(0);

        // Quit app (1st method)  [I'm only using one in real code, but both aren't working]
        android.os.Process.killProcess(android.os.Process.myPid());
        // Quit app (2nd method)
        finish();
    } else {
        //update date value
        Editor editor = PreferenceManager.getDefaultSharedPreferences(this).edit();
        editor.putString("readDate", date);
        editor.commit();

        // Remove notification
        NotificationManager notificationManager = (NotificationManager) this.getSystemService(Context.NOTIFICATION_SERVICE);
        notificationManager.cancel(0);

        //Set theme (not important now)
        Boolean BeanUI = PreferenceManager.getDefaultSharedPreferences(this).getBoolean("bean", false);
                String URL;
                if(BeanUI) {
                        URL = "*****" + PreferenceManager.getDefaultSharedPreferences(this).getString("klasse", "") + "&fc=ffffff&bc=000000";
                } else {
                        URL = "*****" + PreferenceManager.getDefaultSharedPreferences(this).getString("klasse", "");
                }

                String EXTRA_URL = "de.xorg.*****.MESSAGE";
                String EXTRA_NAME = "de.xorg.*****.MESSAGENAME";
                Intent intent2 = new Intent(this, InternetViewer.class);
                intent2.putExtra(EXTRA_URL, URL);
                intent2.putExtra(EXTRA_NAME, ",Vertretungsplan");
            startActivity(intent2);
    }
  }
}

这是创建通知的代码：

// I've censored all private values with ***'s
// CheckService.MC = Context of main activity
// CheckService.NM = NotificationManager
public static void PostNotification(String text, String datum) {
                Intent intentS = new Intent(CheckService.MC, ***************Handler.class);
                Intent intentD = new Intent(CheckService.MC, ***************Handler.class);

                String EXTRA_ACTION = "de.xorg.*****.ACTION";
                String EXTRA_DATE = "de.xorg.*****.VPDATE";

                intentS.putExtra(EXTRA_ACTION, "S");
                intentS.putExtra(EXTRA_DATE, datum);
                intentD.putExtra(EXTRA_ACTION, "D");
                intentD.putExtra(EXTRA_DATE, datum);
                PendingIntent pIntentD = PendingIntent.getActivity(CheckService.MC, 0, intentD, 0);
                PendingIntent pIntentS = PendingIntent.getActivity(CheckService.MC, 0, intentS, 0);

                // Build notification
                Notification n  = new Notification.Builder(CheckService.MC)
                        .setContentTitle("Title")
                        .setContentText(text)
                        .setSmallIcon(R.drawable.vertretung)
                        .setContentIntent(pIntentS)
                        .setAutoCancel(true)
                        .addAction(R.drawable.anzeigen, "Show", pIntentS)
                        .addAction(R.drawable.gelesen, "Dismiss", pIntentD).build();

                CheckService.NM.notify(0, n);
}

我尝试使用»finish();«和»android.os.Process.killProcess(android.os.Process.myPid());«两者都不起作用。

为什么不起作用？是否有更新（更好）的方式来更新设置？

单击通知后，Android Update设置并退出应用程序
