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?

Solution 1

To do this in the layout.xml file:

android:textStyle

Examples:

android:textStyle="bold|italic"

Programmatically the method is:

setTypeface(Typeface tf)

Sets the typeface and style in which the text should be displayed. Note that not all Typeface families actually have bold and italic variants, so you may need to use setTypeface(Typeface, int) to get the appearance that you actually want.

Solution 2

Here is the solution

TextView questionValue = (TextView) findViewById(R.layout.TextView01);
questionValue.setTypeface(null, Typeface.BOLD);

Solution 3

Simply you can do the following:

Set the attribute in XML

  android:textStyle="bold"

Programatically the method is:

TextView Tv = (TextView) findViewById(R.id.TextView);

Typeface boldTypeface = Typeface.defaultFromStyle(Typeface.BOLD);

Tv.setTypeface(boldTypeface);

Hope this helps you thank you.

Solution 4

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)

Solution 5

For case where you are using custom fonts, but do not have bold typeface for the font you can use:

myTextView.setText(Html.fromHtml("<b>" + myText + "</b>");

@nvoigt, his answer differs from many others, at least the second line. Probably it is better than other solutions. I think it is captured from stackoverflow.com/questions/6200533/….
