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 XML

android:textStyle="bold" //only bold
android:textStyle="italic" //only italic
android:textStyle="bold|italic" //bold & italic

You can only use specific fonts sans, serif & monospace via xml, Java code can use custom fonts

android:typeface="monospace" // or sans or serif

Programmatically (Java code)

TextView textView = (TextView) findViewById(R.id.TextView1);

textView.setTypeface(Typeface.SANS_SERIF); //only font style
textView.setTypeface(null,Typeface.BOLD); //only text style(only bold)
textView.setTypeface(null,Typeface.BOLD_ITALIC); //only text style(bold & italic)
textView.setTypeface(Typeface.SANS_SERIF,Typeface.BOLD); 
                                         //font style & text style(only bold)
textView.setTypeface(Typeface.SANS_SERIF,Typeface.BOLD_ITALIC);
                                         //font style & text style(bold & italic)
