android set custom font to a paint
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);
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
