Standard
open class Standard : LineHeightSpan, ParcelableSpan
kotlin.Any | |
↳ | android.text.style.LineHeightSpan.Standard |
Default implementation of the LineHeightSpan
, which changes the line height of the attached paragraph.
For example, a paragraph with its line height equal to 100px can be set like this:
SpannableString string = new SpannableString("This is a multiline paragraph. This is a multiline paragraph."); string.setSpan(new LineHeightSpan.Standard(100), 0, string.length(), Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
Notice that LineHeightSpan will change the line height of the entire paragraph, even though it covers only part of the paragraph.
