How do I draw bold text on a Bitmap?

Question

I want a Bitmap icon with bold text to draw it on map. I have a snippet to write text on image:

Bitmap icon = BitmapFactory.decodeResource(PropertyMapList.this.getResources(),
        R.drawable.location_mark);
TextPaint paint = new TextPaint();
paint.setColor(Color.BLACK);
paint.setTextSize(14);
paint.setFakeBoldText(true);
//paint.setTextAlign(Align.CENTER);
Bitmap copy = icon.copy(Bitmap.Config.ARGB_8888, true); 
Canvas canvas = new Canvas(copy);
//canvas.drawText(jsonObj.getString("district_name"), 5, canvas.getHeight()/2, paint);
String districtName = jsonObj.getString("district_name");
StaticLayout layout = new StaticLayout((districtName.length()>25 ? districtName.substring(0, 24)+"..":districtName)+"\n"+jsonObj.getString("total_properties"), paint, canvas.getWidth()-10,Layout.Alignment.ALIGN_CENTER, 1.3f, 0, false);
canvas.translate(5, canvas.getHeight()/2); //position the text
layout.draw(canvas);

setFakeBoldText(true) doesn't work for me. I would like the text drawn on the Bitmap to be bolded.

Use the setTypeface method on your Paint object to set the font to something with the bold style turned on.

paint.setTypeface(Typeface.create(Typeface.DEFAULT, Typeface.BOLD));

setTypeface allows you to set a font. Fonts have styles, like bold, italic, etc. You can look at the constructors for Typeface and see how to create a font with that style. Once you create one and set it via this call, all future draw commands with this paint will use that font. – Gabe Sechan Jul 29 '13 at 14:38

I tried 6 or 7 answers, and this one was the only one that actually worked. – durbnpoisn Aug 30 '15 at 19:44

A shorter version would be: `paint.setTypeface(Typeface.DEFAULT_BOLD)` rather than calling Typeface.create() – k2col Nov 27 '16 at 12:59

For Custom Fonts:

Typeface font = Typeface.createFromAsset(context.getAssets(), "fonts/bangla/bensen_handwriting.ttf");
Typeface typeface = Typeface.create(font, Typeface.BOLD);

For Normal Fonts:

Typeface typeface = Typeface.create(Typeface.DEFAULT, Typeface.BOLD);
// or
Typeface typeface = Typeface.DEFAULT_BOLD;

and then

paint.setTypeface(typeface);

Kotlin syntax to setup Paint for bold text

paint = Paint(Paint.ANTI_ALIAS_FLAG).also { it.typeface = Typeface.DEFAULT_BOLD }
