How do you change text to bold in Android?

Question

How do you change text/font settings in an Android TextView?

For example, how do you make the text bold

Answer 1

In the ideal world you would set the text style attribute in you layout XML definition like that:

There is a simple way to achieve the same result dynamically in your code by using setTypeface method. You need to pass and object of Typeface class, which will describe the font style for that TextView. So to achieve the same result as with the XML definition above you can do the following:

TextView Tv = (TextView) findViewById(R.id.TextView);
Typeface boldTypeface = Typeface.defaultFromStyle(Typeface.BOLD);
Tv.setTypeface(boldTypeface);

The first line will create the object form predefined style (in this case Typeface.BOLD, but there are many more predefined). Once we have an instance of typeface we can set it on the TextView. And that's it our content will be displayed on the style we defined.
