CharSequence ?
Câu trả lời
Here is a concise explanation of the differences between String, StringBuilder, SpannedString, SpannableString, SpannableStringBuilder, and CharSequence in Android:
A String is immutable, meaning the text cannot be changed once created. It also does not have any spans (formatting information like bold, italic, etc.) associated with it. Use a String when the text does not need to be changed and does not require any styling[1][3].
A StringBuilder has mutable text, allowing you to modify it without creating a new object. However, it does not have any span information - it is just plain text. Use a StringBuilder when you need to change the text, but do not need to style it[1][3].
A SpannedString has immutable text (like a String) and immutable span information. It is a concrete implementation of the Spanned interface. Use a SpannedString when your text has style but you do not need to change either the text or the style after creation[1][3].
A SpannableString has immutable text, but its span information is mutable. It is a concrete implementation of the Spannable interface. Use a SpannableString when your text does not need to be changed but the styling does[1][3].
