android - 全屏通知仅显示为抬头

Question

我已经为这个问题头撞 table 3天了，请告诉我我在哪里迷路了。

当我接到 VoIP 来电时，我会尝试显示全屏通知，就像 PhoneApp 一样。如果用户处于身临其境的 Activity 中，我可以抬头。但是，我只收到一个提醒通知，而从未获得全屏。我也需要通知忽略锁定屏幕。

这是我正在做的事情:

String callJson = call.toJson(uber).toString();
uber.requestWakeState(UberVoice.WAKE_STATE_FULL);

final Notification.Builder builder = new Notification.Builder(uber);
builder.setSmallIcon(R.drawable.switch_notification);
if (image != null) {
    builder.setLargeIcon(image);
}
builder.setOngoing(true);

PendingIntent inCallPendingIntent =
        PendingIntent.getActivity(uber, 234,
                UberVoice.createInCallIntent(), 0);
builder.setContentIntent(inCallPendingIntent);

builder.setContentText(body);
builder.setUsesChronometer(false);

builder.setContentTitle(title);

builder.setCategory(Notification.CATEGORY_CALL);
builder.setVisibility(Notification.VISIBILITY_PUBLIC);

builder.setSound(RingtoneManager.getDefaultUri(RingtoneManager.TYPE_RINGTONE), AudioManager.STREAM_RING);
builder.setVibrate(new long[]{500, 500, 500, 500, 500, 500, 500, 500, 500, 500, 500, 500, 500, 500});

builder.setPriority(Notification.PRIORITY_MAX);
builder.setTicker(title);
builder.setFullScreenIntent(inCallPendingIntent, true);

builder.addAction(R.drawable.hangup_action, "Reject", CallService.getPendingIntent(uber, callJson, CallService.REJECT));
builder.addAction(R.drawable.answer_action, "Answer", CallService.getPendingIntent(uber, callJson, CallService.ANSWER));

NotificationManager notificationManager = (NotificationManager) uber.getSystemService(Context.NOTIFICATION_SERVICE);
Notification notification = builder.build();
notificationManager.notify(INCOMING_CALL_NOTIFICATION_ID, notification);

这里是 createInCallIntent 代码:

public static Intent createInCallIntent() {
    Intent intent = new Intent(Intent.ACTION_MAIN, null);
    intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK
            | Intent.FLAG_ACTIVITY_EXCLUDE_FROM_RECENTS
            | Intent.FLAG_ACTIVITY_NO_USER_ACTION);
    intent.setClassName("<package>", IncomingCallActivity.class.getName());
    return intent;
}

这里是 IncomingCallActivity.onCreate()

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    int flags = WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED
            | WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD
            | WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON;

    getWindow().addFlags(flags);

    setContentView(R.layout.activity_incoming_call);

我已尝试直接启动此 Activity (uber 是应用程序引用)

Intent incomingCallIntent = new Intent(uber, IncomingCallActivity.class);
String callJson = call.toJson(uber).toString();
incomingCallIntent.putExtra("call", callJson);

incomingCallIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

uber.startActivity(incomingCallIntent);

我做错了什么？

如果我正确理解了您的问题，您忘记在 IncomingCallActivity

中添加标志 WindowManager.LayoutParams.FLAG_FULLSCREEN

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    int flags = WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED
            | WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD
            | WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON
            | WindowManager.LayoutParams.FLAG_FULLSCREEN;

    getWindow().addFlags(flags);

此组合需要在屏幕锁定时显示 Activity 。希望对您有所帮助。
