這個控件本人強烈推薦,它會使得布局非常的簡單且高效;
下面這個布局如果是你,你會用多少層?多少控件生成?
告訴你吧,一個SpannableTextView控件就搞定了!
它把TextView和Spannable封裝在了一起,可以在一個TextView中顯示不同的字體顏色,大小,背景色等;
它支持如下樣式:
* Babushka Method????? Internal Span
*???? textSize??????????? AbsoluteSizeSpan
*???? textColor?????????? ForegroundColorSpan
*???? textSizeRelative??? RelativeSizeSpan
*???? backgroundColor???? BackgroundColorSpan
*???? style?????????????? StyleSpan
*???? underline?????????? UnderlineSpan
*???? strike????????????? StrikethroughSpan
*???? superscript???????? SuperscriptSpan
*???? subscript?????????? SubscriptSpan
用法也很簡單:
