How to merge some spannable objects?
I know this is old. But after modifying kotlin stdlib a bit I've got this code:
fun <T> Iterable<T>.joinToSpannedString(separator: CharSequence = ", ", prefix: CharSequence = "", postfix: CharSequence = "", limit: Int = -1, truncated: CharSequence = "...", transform: ((T) -> CharSequence)? = null): SpannedString {
return joinTo(SpannableStringBuilder(), separator, prefix, postfix, limit, truncated, transform)
.let { SpannedString(it) }
}
Hope it might help somebody.
You could use this:
TextUtils.concat(span1, span2);
http://developer.android.com/reference/android/text/TextUtils.html#concat(java.lang.CharSequence...)
Use SpannableStringBuilder
.
Even better- make a kotlin operator overload:
operator fun Spannable.plus(other: Spannable): Spannable{
return SpannableStringBuilder(this).append(other)
}
just throw that in any kotlin file as a top level function.
and the you can concatenate using +
:
val spanA = ...
val spanB = ...
val concatenatedSpan = spanA + spanB
Thanks, it works. I have noticed that I can merge even 3 spannable object:
(Spanned) TextUtils.concat(foo, bar, baz)
