在活动中获取通知消息

Question

我允许用户在Notification 上执行Tap，然后在Launching App 和opening 上执行特定的Activity。

在我打开的那个Activity 中，我想得到我通过通知发送的message

SendNotification(...) 方法：

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);

    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());
}

AnotherActivity.java：

public class AnotherActivity extends AppCompatActivity {

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

        setContentView(R.layout.activity_another);

        // here I would like to get value of messageBody
    }

}

更新 #1

sendNotification(...) {

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

    ....

    }

在 AnotherActivity.java 的 onCreate() 中尝试了两种方式，但没有收到消息

        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
        }

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);

所以你的代码是这样的：

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");
    }
