问题
I'm trying to add a Typeface in my NotificationCompat.Builder ->setContentTitle() and setContentText(). I initialized Typeface by
Typeface banglaFont = Typeface.createFromAsset(this.getAssets(), "kalpurush.ttf");
in IntentService. To create Notification i used following code.
NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(
this)
.setLargeIcon(bitmap)
.setSmallIcon(R.drawable.ic_launcher)
.setContentTitle(userName)
.setAutoCancel(true)
// .setStyle(
// new NotificationCompat.BigTextStyle().bigText(msg))
.setStyle(new NotificationCompat.InboxStyle())
.setVibrate(pattern).setLights(Color.BLUE, 500, 500)
.setSound(alarmSound).setContentText(msg);
mBuilder.setContentIntent(contentIntent);
Notification n = mBuilder.build();
int min = 1001;
int max = 2000;
Random r = new Random();
int randomNumber = r.nextInt(max - min + 1) + min;
int notID = randomNumber;
mNotificationManager.notify(notID, n);
But i cann't understand how can i set the Typeface in my Notification title and content. Any suggestions or reference would be highly appreciated.
Thanks in advance.

this is very useful answer, done by creating own typefacespan http://www.codeproject.com/Questions/567126/AndroidplusNotificationplusinplusotherpluslanguage
EDIT:
custom_notification.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/custom_notification"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical" >
<ImageView
android:id="@+id/notification_image"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_centerVertical="true"
android:layout_margin="5dip"
android:src="@drawable/ic_launcher" />
<TextView
android:id="@+id/notification_text"
style="@style/NotificationText"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginBottom="1dp"
android:layout_toRightOf="@+id/notification_image"
android:maxLines="3"
android:layout_centerVertical="true"
android:ellipsize="end"
android:text="@string/app_name" />
</RelativeLayout>
code for android to notification method
private static void generateNotification(Context context,
SpannableStringBuilder message) {
int icon = R.drawable.ic_launcher;
// create new id
Date date = new Date();
int notificationid = (int) date.getTime();
long when = System.currentTimeMillis();
NotificationManager notificationManager = (NotificationManager) context
.getSystemService(Context.NOTIFICATION_SERVICE);
Notification notification = new Notification(icon, message, when);
String title = context.getString(R.string.app_name);
Intent notificationIntent = new Intent(context, MainActivity.class);
// set intent so it does not start a new activity
notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP
| Intent.FLAG_ACTIVITY_SINGLE_TOP);
PendingIntent intent = PendingIntent.getActivity(context,
notificationid, notificationIntent, 0);
RemoteViews contentView = new RemoteViews(context
.getApplicationContext().getPackageName(),
R.layout.custom_notification);
contentView.setImageViewResource(R.id.notification_image,
R.drawable.ic_launcher);
// contentView.setTextViewText(R.id.notification_title,
// "My custom notification title");
contentView.setTextViewText(R.id.notification_text, message);
notification.contentView = contentView;
notification.contentIntent = intent;
// notification.setLatestEventInfo(context, title, message, intent);
notification.flags |= Notification.FLAG_AUTO_CANCEL;
notificationManager.notify(notificationid, notification);
}
call this method like this:
SpannableStringBuilder sb = new SpannableStringBuilder("মুখ্যমন্ত্রী হওয়ার পর থেকেই রাজ্যের হাতে আরও বেশি ক্ষমতা 4দেওয়ার দাবিতে বারেবারে সরব হয়েছেন তিনি");
Typeface font = Typeface.createFromAsset(getAssets(), "kalpurush.ttf");
sb.setSpan(new CustomTypefaceSpan("", font), 0, sb.length() - 1,
Spanned.SPAN_EXCLUSIVE_INCLUSIVE);
generateNotification(context, sb);
UPDATE:
public class CustomTypefaceSpan extends TypefaceSpan {
private final Typeface newType;
public CustomTypefaceSpan(String family, Typeface type) {
super(family);
newType = type;
}
@Override
public void updateDrawState(TextPaint ds) {
applyCustomTypeFace(ds, newType);
}
@Override
public void updateMeasureState(TextPaint paint) {
applyCustomTypeFace(paint, newType);
}
private static void applyCustomTypeFace(Paint paint, Typeface tf) {
int oldStyle;
Typeface old = paint.getTypeface();
if (old == null) {
oldStyle = 0;
} else {
oldStyle = old.getStyle();
}
int fake = oldStyle & ~tf.getStyle();
if ((fake & Typeface.BOLD) != 0) {
paint.setFakeBoldText(true);
}
if ((fake & Typeface.ITALIC) != 0) {
paint.setTextSkewX(-0.25f);
}
paint.setTypeface(tf);
}
}
i hope this is very helpful

Best way to set typeface on notification is convert text as Bitmap and Render in the canvas.for render custom notification we want to use remoteview.
custome_notification.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/layout"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:padding="3dp"
android:orientation="horizontal"
>
<ImageView android:id="@+id/logo"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:layout_alignParentLeft="true"
android:layout_marginRight="1dp"
android:src="@drawable/ic_launcher"/>
<ImageView android:id="@+id/notification_img"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:layout_alignParentLeft="true"
android:layout_marginRight="1dp" />
</LinearLayout>
public void showCustomNotifications(Context context, String text){
DisplayMetrics displayMetrics = context.getResources().getDisplayMetrics();
int width = displayMetrics.widthPixels;
Bitmap myBitmap = Bitmap.createBitmap(width - 72, 84, Bitmap.Config.ARGB_4444);
Canvas myCanvas = new Canvas(myBitmap);
Paint paint = new Paint();
Typeface font2 = Typeface.createFromAsset(context.getAssets(), context.getResources().getString(R.string.sinhalaFont));
paint.setAntiAlias(true);
paint.setSubpixelText(true);
paint.setTypeface(font2);
paint.setStyle(Paint.Style.FILL);
//paint.setColor(Color.BLACK);
paint.setTextSize(50);
paint.setTextAlign(Align.LEFT);
myCanvas.drawText(text, 80, 60, paint);
int icon = R.drawable.ic_launcher;
// create new id
Date date = new Date();
int notificationid = (int) date.getTime();
long when = System.currentTimeMillis();
NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
Notification notification = new Notification(icon, "Anynews", when);
//String title = getString(R.string.app_name);
Intent notificationIntent = new Intent(context, MainActivity.class);
// set intent so it does not start a new activity
notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP
| Intent.FLAG_ACTIVITY_SINGLE_TOP);
PendingIntent intent = PendingIntent.getActivity(context,
notificationid, notificationIntent, 0);
RemoteViews contentView = new RemoteViews(context.getPackageName(),
R.layout.custom_notification);
contentView.setImageViewBitmap(R.id.notification_img,
myBitmap);
// contentView.setTextViewText(R.id.notification_title,
// "My custom notification title");
//contentView.setTextViewText(R.id.notification_text, message);
notification.contentView = contentView;
notification.contentIntent = intent;
// notification.setLatestEventInfo(context, title, message, intent);
notification.flags |= Notification.FLAG_AUTO_CANCEL;
notificationManager.notify(notificationid, notification);
}
