How to set the font style to bold, italic and underlined in an Android TextView?

I want to make a TextView's content bold, italic and underlined. I tried the following code and it works, but doesn't underline.

<Textview android:textStyle="bold|italic" ..

How do I do it? Any quick ideas?

Solution 1:

This should make your TextView bold, underlined and italic at the same time.

strings.xml

<resources>
    <string name="register"><u><b><i>Copyright</i></b></u></string>
</resources>

To set this String to your TextView, do this in your main.xml

<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/textview"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:text="@string/register" />

or In JAVA,

TextView textView = new TextView(this);
textView.setText(R.string.register);

Sometimes the above approach will not be helpful when you might have to use Dynamic Text. So in that case SpannableString comes into action.

String tempString="Copyright";
TextView text=(TextView)findViewById(R.id.text);
SpannableString spanString = new SpannableString(tempString);
spanString.setSpan(new UnderlineSpan(), 0, spanString.length(), 0);
spanString.setSpan(new StyleSpan(Typeface.BOLD), 0, spanString.length(), 0);
spanString.setSpan(new StyleSpan(Typeface.ITALIC), 0, spanString.length(), 0);
text.setText(spanString);

OUTPUT

Solution 2:

I don't know about underline, but for bold and italic there is "bolditalic". There is no mention of underline here: http://developer.android.com/reference/android/widget/TextView.html#attr_android:textStyle

Mind you that to use the mentioned bolditalic you need to, and I quote from that page

Must be one or more (separated by '|') of the following constant values.

so you'd use bold|italic

You could check this question for underline: Can I underline text in an android layout?

Solution 3:

Or just like this in Kotlin:

val tv = findViewById(R.id.textViewOne) as TextView
tv.setTypeface(null, Typeface.BOLD_ITALIC)
// OR
tv.setTypeface(null, Typeface.BOLD or Typeface.ITALIC)
// OR
tv.setTypeface(null, Typeface.BOLD)
// OR
tv.setTypeface(null, Typeface.ITALIC)
// AND
tv.paintFlags = tv.paintFlags or Paint.UNDERLINE_TEXT_FLAG

Or in Java:

TextView tv = (TextView)findViewById(R.id.textViewOne);
tv.setTypeface(null, Typeface.BOLD_ITALIC);
// OR
tv.setTypeface(null, Typeface.BOLD|Typeface.ITALIC);
// OR
tv.setTypeface(null, Typeface.BOLD);
// OR
tv.setTypeface(null, Typeface.ITALIC);
// AND
tv.setPaintFlags(tv.getPaintFlags()|Paint.UNDERLINE_TEXT_FLAG);

Keep it simple and in one line :)
