Answer 2

使用 NotificationListenerService ，我们可以收听所有通知和来电。

   public class NotificationService extends NotificationListenerService {

    Context context;

    @Override

    public void onCreate() {

        super.onCreate();
        context = getApplicationContext();

    }
    @Override

    public void onNotificationPosted(StatusBarNotification sbn) {
        String pack = sbn.getPackageName();
        String ticker ="";
        if(sbn.getNotification().tickerText !=null) {
            ticker = sbn.getNotification().tickerText.toString();
        }
        Bundle extras = sbn.getNotification().extras;
        String title = extras.getString("android.title");
        String text = extras.getCharSequence("android.text").toString();
        int id1 = extras.getInt(Notification.EXTRA_SMALL_ICON);
        Bitmap id = sbn.getNotification().largeIcon;


        Log.i("Package",pack);
        Log.i("Ticker",ticker);
        Log.i("Title",title);
        Log.i("Text",text);

        Intent msgrcv = new Intent("Msg");
        msgrcv.putExtra("package", pack);
        msgrcv.putExtra("ticker", ticker);
        msgrcv.putExtra("title", title);
        msgrcv.putExtra("text", text);
        if(id != null) {
            ByteArrayOutputStream stream = new ByteArrayOutputStream();
            id.compress(Bitmap.CompressFormat.PNG, 100, stream);
            byte[] byteArray = stream.toByteArray();
            msgrcv.putExtra("icon",byteArray);
        }
        LocalBroadcastManager.getInstance(getApplicationContext()).sendBroadcast(msgrcv);

    }

    @Override

    public void onNotificationRemoved(StatusBarNotification sbn) {
        Log.i("Msg","Notification Removed");

    }
}
