Question

是否可以将从textView中获取的字符串添加到状态栏。我想不断地显示文本，动态更新为来自应用程序主要活动的textView。

TextView message = (TextView) findViewById(R.id.textView1);
message.setText("This I want to add to status bar");

Answer 1

是的，你可以

private static void generateNotification(Context context, String message) {
        int icon = R.drawable.ic_status;
        long when = System.currentTimeMillis();
        NotificationManager notificationManager = (NotificationManager) context
                .getSystemService(Context.NOTIFICATION_SERVICE);
        Notification notification = new Notification(icon, message, when);
        String title = context.getString(R.string.app_name); // Here you can pass the value of your TextView
        Intent notificationIntent = new Intent(context, SplashScreen.class);
        notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP
                | Intent.FLAG_ACTIVITY_SINGLE_TOP);
        PendingIntent intent = PendingIntent.getActivity(context, 0,
                notificationIntent, 0);
        notification.setLatestEventInfo(context, title, message, intent);
        notification.flags |= Notification.FLAG_AUTO_CANCEL;
        notificationManager.notify(0, notification);
    }

Answer 2

TextView message =（TextView）findViewById（R.id.textView1）; message.setText（“我想添加到状态栏”）;

ActionBar actionBar = getSupportActionBar（）; actionBar.setTittle（message.getText（）的toString（））;

那应该解决你的问题。
