通知不会在Android 10中被取消 [英] Notification does not get cancelled in Android 10

问题描述

问题:当我直接回复该通知时，我想取消该通知.它可以在Android N上运行，但不能在Android 10上运行.

Problem: I want to cancel a Notification when I directly reply to that Notification. It works in Android N but doesn't work on Android 10.

我的代码如下:

MainActivity.java

    public class MainActivity extends AppCompatActivity {

    public static final int NOTIFICATION_ID = 1256;
    public static final String CHANNEL_1_ID = "channel1";

    private Button btnDisplayNotification;

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

        createNotificationChannel();

        btnDisplayNotification = findViewById(R.id.btnDisplayNotification);

        btnDisplayNotification.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {

                displayNotification(MainActivity.this);
            }
        });
    }

    private void createNotificationChannel() {

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {

            NotificationChannel channel1 = new NotificationChannel(
                    CHANNEL_1_ID,
                    "Channel 1",
                    NotificationManager.IMPORTANCE_HIGH
            );
            channel1.setDescription("This is Channel 1");

            NotificationManager manager = getSystemService(NotificationManager.class);
            manager.createNotificationChannel(channel1);
        }
    }

    public static void displayNotification(Context context) {

        Intent replyIntent;
        PendingIntent replyPendingIntent = null;

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {

            replyIntent = new Intent(context, ReceiverIntentService.class);
            replyPendingIntent = PendingIntent.getService(context, 0, replyIntent, PendingIntent.FLAG_CANCEL_CURRENT);

        } else {

            replyIntent = new Intent(context, ReplyActivity.class);
            replyIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            replyPendingIntent = PendingIntent.getActivity(context, 0, replyIntent, PendingIntent.FLAG_CANCEL_CURRENT);
        }

        RemoteInput remoteInput = new RemoteInput.Builder("key_text_reply")
                .setLabel("Your answer...")
                .build();

        NotificationCompat.Action replyAction = new NotificationCompat.Action.Builder(
                R.drawable.ic_reply,
                "Reply", replyPendingIntent)
                .addRemoteInput(remoteInput)
                .build();

        NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(context, CHANNEL_1_ID);
        notificationBuilder.setSmallIcon(R.drawable.ic_launcher_background)
                .addAction(replyAction)
                .setContentTitle("Hot Jobs")
                .setContentText("Check out hot jobs based on your skills")
                .setPriority(NotificationCompat.PRIORITY_HIGH)
                .setAutoCancel(true);

        NotificationManagerCompat notificationManager = NotificationManagerCompat.from(context);
        notificationManager.notify("NOTI_TAG", NOTIFICATION_ID, notificationBuilder.build());
    }
}

ReceiverIntentService.java

    public class ReceiverIntentService extends IntentService {

    public ReceiverIntentService() {
        super("blah");
    }

    @Override
    protected void onHandleIntent(@Nullable Intent intent) {

        Bundle remoteInput = RemoteInput.getResultsFromIntent(intent);

        if (remoteInput != null) {

            CharSequence replyText = remoteInput.getCharSequence("key_text_reply");

            Log.e("NotiReply", "IS Reply is: " + replyText);

            NotificationManagerCompat notificationManager = NotificationManagerCompat.from(getApplicationContext());
            if (notificationManager != null) {
                stopForeground( true );
                notificationManager.cancel("NOTI_TAG", NOTIFICATION_ID);
            }
        }
    }
}

AndroidManifest.xml

    <?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="web.b.notificationreplydemo2">

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_notifications_black_24dp"
        android:label="@string/app_name"
        android:roundIcon="@drawable/ic_notifications_black_24dp"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">

        <activity android:name=".ReplyActivity"></activity>

        <activity android:name=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

        <receiver android:name=".DirectReplyReceiver" />

        <service
            android:name=".ReceiverIntentService"
            android:exported="false" />
    </application>

</manifest>

在上面的代码中，我尝试使用 BroadcastReceiver ，但是发生了同样的问题.

In the above code, I have tried using BroadcastReceiver, but the same ISSUE happens.

我正在附上我要实现的屏幕截图.在下面.

I'm attaching a screenshot of what I want to achieve. It's below.

我在ANDROID 8和ANDROID 9模拟器上运行相同的项目.它可以在ANDROID 8上使用，但在ANDROID 9上可以使用相同的问题(回复后不会取消通知).

I run the same project on ANDROID 8 and ANDROID 9 emulators. It worked as aspected on ANDROID 8 but the same issue on ANDROID 9(Does not cancel notification after replying).

我在这里找到了相同的问题.

I found the same question here.

推荐答案

我建议您做以下事情:

1. 检查您的服务的onHandleIntent方法是否被调用
2. 检查remoteInput是否不为空
3. 检查notificationManager是否不为空
4. 尝试通过不带标签的ID取消通知

1. check if your services onHandleIntent method is called
2. check if remoteInput is not null
3. check if notificationManager is not null
4. try to cancel notification by ID without a tag
