Use a custom contentView on your Notification Builder

To define a custom notification layout, start by instantiating a RemoteViews object that inflates an XML layout file. Then, instead of calling methods such as setContentTitle(), call setContent(). To set content details in the custom notification, use the methods in RemoteViews to set the values of the view's children:

Create an XML layout for the notification in a separate file. You can use any file name you wish, but you must use the extension .xml In your app, use RemoteViews methods to define your notification's icons and text. Put this RemoteViews object into your NotificationCompat.Builder by calling setContent(). Avoid setting a background Drawable on your RemoteViews object, because your text color may become unreadable.

custom_push.xml has my custom views R.id.image,R.id.text,R.id.title

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/layout"
    android:layout_width="fill_parent"
    android:layout_height="64dp"
    android:padding="10dp" >
    <ImageView
        android:src="@mipmap/ic_launcher"
        android:id="@+id/image"
        android:layout_width="wrap_content"
        android:layout_height="fill_parent"
        android:layout_alignParentLeft="true"
        android:layout_marginRight="10dp" />
    <TextView
        android:textSize="13dp"
        android:textColor="#000"
        android:text="Testing"
        android:id="@+id/title"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_toRightOf="@id/image"
        />
    <TextView
        android:textSize="13dp"
        android:textColor="#000"
        android:text="Testing is awecome"
        android:id="@+id/text"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_toRightOf="@id/image"
        android:layout_below="@id/title"
         />
</RelativeLayout>

Instantiating a RemoteViews object and set it,

RemoteViews contentView = new RemoteViews(getPackageName(), R.layout.custom_push);
contentView.setImageViewResource(R.id.image, R.mipmap.ic_launcher);
contentView.setTextViewText(R.id.title, "Custom notification");
contentView.setTextViewText(R.id.text, "This is a custom layout");

NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.icon)
.setContent(contentView);

Notification notification = mBuilder.build();
notification.flags |= Notification.FLAG_AUTO_CANCEL;
notification.defaults |= Notification.DEFAULT_SOUND;
notification.defaults |= Notification.DEFAULT_VIBRATE;
notificationManager.notify(1, notification);

Just wanted to point out that `fill_parent` is deprecated and from API 8 one should use `match_parent`. See: https://developer.android.com/reference/android/view/ViewGroup.LayoutParams.html#FILL_PARENT — vector, Oct 19 '17 at 14:00
setting style to DecoratedCustomViewStyle() is necessary for custom views — S.R, Oct 20 '18 at 15:37

I used BitTextStyle() to add highlighted text in notification.

return new NotificationCompat.Builder(context)
       .setSmallIcon(R.drawable.ic_mono)
       .setContentTitle(title)
       .setContentText(message)
       .setLargeIcon(icon)
       .setColor(ContextCompat.getColor(context, R.color.notification_color))
       .setStyle(new NotificationCompat.BigTextStyle().bigText(title))
       .setStyle(new NotificationCompat.BigTextStyle().bigText(message).setSummaryText("#hashtag"))
       .setShowWhen(true)
       .setAutoCancel(true);

This code worked for me.

    private static RemoteViews contentView;
    private static Notification notification;
    private static NotificationManager notificationManager;
    private static final int NotificationID = 1005;
    private static NotificationCompat.Builder mBuilder;

    private void RunNotification() {

        notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
        mBuilder = new NotificationCompat.Builder(getApplicationContext(), "notify_001");

        contentView = new RemoteViews(getPackageName(), R.layout.my_notification_layout);
        contentView.setImageViewResource(R.id.image, R.mipmap.ic_launcher);
        Intent switchIntent = new Intent(this, BackgroundService.switchButtonListener.class);
        PendingIntent pendingSwitchIntent = PendingIntent.getBroadcast(this, 1020, switchIntent, 0);
        contentView.setOnClickPendingIntent(R.id.flashButton, pendingSwitchIntent);

        mBuilder.setSmallIcon(R.mipmap.newicon);
        mBuilder.setAutoCancel(false);
        mBuilder.setOngoing(true);
        mBuilder.setPriority(Notification.PRIORITY_HIGH);
        mBuilder.setOnlyAlertOnce(true);
        mBuilder.build().flags = Notification.FLAG_NO_CLEAR | Notification.PRIORITY_HIGH;
        mBuilder.setContent(contentView);

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            String channelId = "channel_id";
            NotificationChannel channel = new NotificationChannel(channelId, "channel name", NotificationManager.IMPORTANCE_HIGH);
            channel.enableVibration(true);
            channel.setVibrationPattern(new long[]{100, 200, 300, 400, 500, 400, 300, 200, 400});
            notificationManager.createNotificationChannel(channel);
            mBuilder.setChannelId(channelId);
        }

        notification = mBuilder.build();
        notificationManager.notify(NotificationID, notification);
    }

this is my notification layout

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="50dp"
    android:background="#e9ebe9">

    <ImageView
        android:id="@+id/flashButton"
        android:layout_width="180dp"
        android:layout_height="50dp"
        android:layout_alignParentRight="true"
        android:layout_centerVertical="true"
        android:layout_marginRight="-20dp"
        android:src="@drawable/turnoff2" />

    <ImageView
        android:layout_width="100dp"
        android:layout_height="45dp"
        android:layout_alignParentLeft="true"
        android:layout_marginLeft="-10dp"
        android:layout_marginTop="5dp"
        android:layout_marginBottom="5dp"
        android:src="@mipmap/newicon" />

    <RelativeLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerVertical="true"
        android:layout_marginLeft="80dp">

        <TextView
            android:id="@+id/title"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignParentLeft="true"
            android:text="Flashlight"
            android:textColor="#000000"
            android:textSize="13sp" />

        <TextView
            android:id="@+id/charging"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_below="@+id/title"
            android:layout_alignParentLeft="true"
            android:layout_marginTop="3dp"
            android:text="90% Charging"
            android:textColor="#000000"
            android:textSize="13sp" />
    </RelativeLayout>

</RelativeLayout>

I hope this could help you

Will this work work for every notification received on the app (even FCM ) and where do i put this file in order for it to work ? — austin, Feb 26 '22 at 11:33

I guess what you're looking for is .setSubText(). The flipkart notification you have pointed out is definitely not a custom view.

NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
                        .setSmallIcon(icon)
                        .setSubText("Limited Stocks, Don't Wait!") <-------
                        .setContentTitle("Custom Notification Title")
notificationBuilder.notify(1, notificationBuilder.build());
