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)

Answer 2

Define a new style with the format you want in the style.xml file in the values folder

<style name="TextViewStyle" parent="AppBaseTheme">
    <item name="android:textStyle">bold</item>
    <item name="android:typeface">monospace</item>
    <item name="android:textSize">16sp</item>
    <item name="android:textColor">#5EADED</item>

</style>

Then apply this style to the TextView by writing the following code with the properties of the TextView

style="@style/TextViewStyle"

Answer 3

The best way to go is:

TextView tv = findViewById(R.id.textView);
tv.setTypeface(Typeface.DEFAULT_BOLD);

Answer 4

Set the attribute

android:textStyle="bold"

Answer 5

If you're drawing it then this will do it:

TextPaint.setFlags(Paint.FAKE_BOLD_TEXT_FLAG);
