void setSpan (Object what, int start, int end, int flags)
參數(shù)說(shuō)明：
object what ：對(duì)應(yīng)的各種Span
int start：開(kāi)始應(yīng)用指定Span的位置，索引從0開(kāi)始
int end：結(jié)束應(yīng)用指定Span的位置，特效并不包括這個(gè)位置。比如如果這里數(shù)為3（即第4個(gè)字符），第4個(gè)字符不會(huì)有任何特效。
int flags：取值有如下四個(gè)
Spannable.SPAN_EXCLUSIVE_EXCLUSIVE：前后都不包括，即在指定范圍的前面和后面插入新字符都不會(huì)應(yīng)用新樣式
Spannable.SPAN_EXCLUSIVE_INCLUSIVE ：前面不包括，后面包括。即僅在范圍字符的后面插入新字符時(shí)會(huì)應(yīng)用新樣式
Spannable.SPAN_INCLUSIVE_EXCLUSIVE ：前面包括，后面不包括。
Spannable.SPAN_INCLUSIVE_INCLUSIVE ：前后都包括。
