设备锁定时全屏通知不可见

编程问答 2022-04-23

问题描述

当我接到电话时，我正在开发一个呼叫应用程序（基于 VoIP） 我显示一个通知弹出窗口来接听或拒绝一个电话，但该弹出通知在 3-5 秒内不可见，我也想显示全屏设备锁定时的通知。我已经完成了一些代码，但没有奏效。设备锁定时我无法接听电话。

1] 通知渠道

notificationmanager = (notificationmanager) context.getSystemService(Context.NOTIFICATION_SERVICE);
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            /* Create or update. */
            NotificationChannel channel = new NotificationChannel(CHANNEL_ID,aContext.getResources().getString(R.string.app_name),notificationmanager.IMPORTANCE_HIGH);//IMPORTANCE_DEFAULT);

            notificationmanager.createNotificationChannel(channel);


        }
        createNotificationChannel();
        if (!isInit) {
            cancelAll();
            cancelCalls();
            isInit = true;
        }

2] 来电通知

@SuppressLint("WrongConstant")
    public void showNotificationForIncomingCall(SipCallSession callInfo) {
        @SuppressWarnings("deprecation")
        int icon = android.R.drawable.stat_sys_phone_call;
        CharSequence tickerText = context.getText(R.string.ongoing_call);
        long when = System.currentTimeMillis();
        Intent callNotifIntent;
        tickerText = context.getText(R.string.incoming_call);

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            if (inComingCallNotification == null) {
                inComingCallNotification = new Builder(context);
                inComingCallNotification.setSmallIcon(icon);
                inComingCallNotification.setTicker(tickerText);
                inComingCallNotification.setPriority(NotificationCompat.PRIORITY_HIGH);
                inComingCallNotification.setCategory(NotificationCompat.CATEGORY_CALL);
                inComingCallNotification.setWhen(when);
                inComingCallNotification.setChannelId(IN_CHANNEL_ID);
                inComingCallNotification.setongoing(true);
            }
        } else {
            if (inComingCallNotification == null) {
                inComingCallNotification = new Builder(context);
                inComingCallNotification.setSmallIcon(icon);
                inComingCallNotification.setTicker(tickerText);
                inComingCallNotification.setWhen(when);
                inComingCallNotification.setongoing(true);
            }
        }
        RemoteViews notificationLayoutHeadsUp =
                new RemoteViews(
                        context.getPackageName(),R.layout.incoming_call_notification_heads_up);
//        notificationLayoutHeadsUp.setTextViewText(R.id.caller,getString(R.string.app_name));
        notificationLayoutHeadsUp.setTextViewText(R.id.sip_uri,formatRemoteContactString(callInfo.getRemoteContact(),callInfo));

        Log.d("Notification: ","showNotification: called: ");

        Intent hangupIntent = new Intent(context,NotificationbroadcastReceiver.class);
        String INTENT_CANCEL_CALL_FORWARDING_ACTION = "com.android.cancel_call";

        hangupIntent.setAction(INTENT_CANCEL_CALL_FORWARDING_ACTION);

        Intent startIntent = new Intent(context,NotificationbroadcastReceiver.class);
        String INTENT_START_CALL_FORWARDING_ACTION = "com.android.start_call";
        startIntent.setAction(INTENT_START_CALL_FORWARDING_ACTION);

        PendingIntent hangupPendingIntent =
                PendingIntent.getbroadcast(context,131,hangupIntent,PendingIntent.FLAG_UPDATE_CURRENT);

        PendingIntent startPendingIntent =
                PendingIntent.getbroadcast(
                        context,startIntent,PendingIntent.FLAG_UPDATE_CURRENT);

        notificationLayoutHeadsUp.setonClickPendingIntent(R.id.accept_btn,startPendingIntent);
        notificationLayoutHeadsUp.setonClickPendingIntent(R.id.reject_btn,hangupPendingIntent);

        prefManager.setBackgroundCall(true);
        Intent notificationIntent = SipServiceNew.buildCallUiIntent(context,callInfo);
        PendingIntent contentIntent = PendingIntent.getActivity(context,notificationIntent,0);

        inComingCallNotification.setContentText(formatRemoteContactString(callInfo.getRemoteContact(),callInfo));
        inComingCallNotification.setContentIntent(contentIntent);
        inComingCallNotification.setongoing(true)
                .setFullScreenIntent(contentIntent,true)
//                .setCustomHeadsUpContentView(notificationLayoutHeadsUp)
                .addAction(R.drawable.cancel_forwarding_bg,"Decline",hangupPendingIntent)
                .addAction(R.drawable.start_forwarding_bg,"Accept",startPendingIntent)
                .setVisibility(Notification.VISIBILITY_PUBLIC);
        Notification notification = inComingCallNotification.build();
        notification.flags |= Notification.FLAG_NO_CLEAR;
        notificationmanager.notify(131,notification);

    }

3] 清单权限

<uses-permission android:name="android.permission.WAKE_LOCK" />
android:showOnLockScreen="true"
