Android 获取活动中的通知消息

我允许用户点击通知，然后启动应用程序并打开特定活动

在我正在打开的活动中，我希望得到通过通知发送的消息

发送通知。。。方法：

AnotherActivity.java：

更新1

发送通知。。。{

在onCreate of AnotherActivity.java中尝试了这两种方法，但未收到消息

        String message=getIntent().getStringExtra("message");
        Toast.makeText(YouTubeActivity.this, message, Toast.LENGTH_LONG).show();

        Bundle extras = getIntent().getExtras();
        if (extras != null) {
            String value = extras.getString("message");
            Toast.makeText(YouTubeActivity.this, value, Toast.LENGTH_LONG).show();
            //The key argument here must match that used in the other activity
        }

只要这样做：

Intent intent = new Intent(this, MainActivity.class);
    intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
    intent.putExtra("AnotherActivity", TrueOrFalse);
    intent.putExtra("message", messageBody);

因此，您的代码如下所示：

private void sendNotification(String messageTitle, String messageBody, Bitmap image, String TrueOrFalse) {

    Intent intent = new Intent(this, MainActivity.class);
    intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
    intent.putExtra("AnotherActivity", TrueOrFalse);
    intent.putExtra("message", messageBody);


    PendingIntent pendingIntent = PendingIntent.getActivity(this, 0 /* Request code */, intent,
            PendingIntent.FLAG_ONE_SHOT);

    Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
    NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
            .setLargeIcon(image)/*Notification icon image*/
            .setSmallIcon(R.mipmap.ic_launcher)
            .setContentTitle(messageTitle)
            .setContentText(messageBody)
            .setStyle(new NotificationCompat.BigPictureStyle()
                    .bigPicture(image))/*Notification with Image*/
            .setAutoCancel(true)
            .setSound(defaultSoundUri)
            .setContentIntent(pendingIntent);

    NotificationManager notificationManager =
            (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);

    notificationManager.notify(0 /* ID of notification */, notificationBuilder.build());
}

要获取数据，请执行以下操作：

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

        setContentView(R.layout.activity_another);

        // here I would like to get value of messageBody
        String message=getIntent().getStringExtra("message");
    }

当你点击通知启动MainActivity或AnotherActivity？AnotherActivity.java好的我现在知道了，我必须调用AnotherActivity.java来代替MainActivity.jav让我试试这一个……过去两天我太笨了，我在想为什么我没有收到消息……无论如何，先让我试试看，你可以得到this intent.putextraonotheractivity，TrueOrFalse；？完成…我只是用AnotherActivity.java代替MainActivity.java…谢谢

Intent intent = new Intent(this, MainActivity.class);
    intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
    intent.putExtra("AnotherActivity", TrueOrFalse);
    intent.putExtra("message", messageBody);

private void sendNotification(String messageTitle, String messageBody, Bitmap image, String TrueOrFalse) {

    Intent intent = new Intent(this, MainActivity.class);
    intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
    intent.putExtra("AnotherActivity", TrueOrFalse);
    intent.putExtra("message", messageBody);


    PendingIntent pendingIntent = PendingIntent.getActivity(this, 0 /* Request code */, intent,
            PendingIntent.FLAG_ONE_SHOT);

    Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
    NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
            .setLargeIcon(image)/*Notification icon image*/
            .setSmallIcon(R.mipmap.ic_launcher)
            .setContentTitle(messageTitle)
            .setContentText(messageBody)
            .setStyle(new NotificationCompat.BigPictureStyle()
                    .bigPicture(image))/*Notification with Image*/
            .setAutoCancel(true)
            .setSound(defaultSoundUri)
            .setContentIntent(pendingIntent);

    NotificationManager notificationManager =
            (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);

    notificationManager.notify(0 /* ID of notification */, notificationBuilder.build());
}

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

        setContentView(R.layout.activity_another);

        // here I would like to get value of messageBody
        String message=getIntent().getStringExtra("message");
    }
