android set custom font to a paint

Questions:

I want to draw a text to a paint. How to draw it with a custom font (ex Helvetica ) and bold also? I would preffer to use a system font and not create it from assets. Thanks.

How to&Answers:

If by “custom font” you mean a font that you are supplying as an asset, the following code should work:

Typeface plain = Typeface.createFromAsset(assetManager, pathToFont); 
Typeface bold = Typeface.create(plain, Typeface.DEFAULT_BOLD)
Paint paint = new Paint();
paint.setTypeface(bold);
canvas.drawText("Sample text in bold",0,0,paint);

Answer:

If you are using Android’s new Fonts in XML for your fonts, then to get the typeface used for paint you can use:

val customTypeface = ResourcesCompat.getFont(context, R.font.myfont)

or if your min Android API >= 26

val customTypeface = resources.getFont(R.font.myfont)

Then to apply it to your paint object:

mTextPaint.typeface = customTypeface

Answer:

Use this for paint class:

 Paint paint = new Paint();
   paint.setTypeface(Typeface.create("Arial",Typeface.ITALIC));

Answer:

If you already have a font in use and want to use a bold version of that you can do this.

currentPainter = new Paint(Paint.ANTI_ALIAS_FLAG);
currentPainter.setColor(Color.WHITE);
currentPainter.setTextSize(Utils.sp2px(getResources(), 14)); // set font size
Typeface currentTypeFace =   currentPainter.getTypeface();
Typeface bold = Typeface.create(currentTypeFace, Typeface.BOLD);
currentPainter.setTypeface(bold);

I used the answer above, but this modification was necessary for me – so just thought I’d mention it

Answer:

If you want to use a font from resources (Kotlin):

val textPaint = TextPaint()
textPaint.typeface = resources.getFont(R.font.font_name)

This might not be related to the question, but this is what I was looking for – maybe somebody would need it too.
