SpannableStringBuilder to create String with multiple fonts/text sizes etc Example?

Question

I need to create a String placed in a TextView that will display a string like this:

First Part Not Bold BOLD rest not bold

Answer 1

We can also use SpannableStringBuilder with TextAppearanceSpan to accomplish that. Follow the below steps to implement like that.

1. Create a style in styles.xml.

2. Use the below code.

SpannableStringBuilder builder = new SpannableStringBuilder("First Part Not Bold BOLD rest not bold");
builder.setSpan(new TextAppearanceSpan(this, R.style.BoldStyle), 20, 24, 0);
((TextView)findViewById(R.id.tv7)).setText(builder);

That's it. Hope it'll help someone.
