android控件使用-----SpannableString

这里我没事写了下效果方便自己记住，也就写出来（( ⊙ o ⊙ )！）

spannableString.setSpan(colorSpan, 5, spannableString.length(), Spanned.SPAN_INCLUSIVE_EXCLUSIVE);

首先说下这个方法的参数

第一参数是效果

第二的参数起始位置

第三个参数终点位置

第四个参数如下

Spanned.SPAN_INCLUSIVE_EXCLUSIVE 从起始下标到终了下标，包括起始下标

Spanned.SPAN_INCLUSIVE_INCLUSIVE 从起始下标到终了下标，同时包括起始下标和终了下标

Spanned.SPAN_EXCLUSIVE_EXCLUSIVE 从起始下标到终了下标，但都不包括起始下标和终了下标

Spanned.SPAN_EXCLUSIVE_INCLUSIVE 从起始下标到终了下标，包括终了下标

用的时候再看吧

都是用法我写在一起了

给出代码清楚明白

xml文件都给你们直接看效果（良心吧）

在最后的点击事件中

//设置该句使文本的超连接起作用
textView.setMovementMethod(LinkMovementMethod.getInstance());
//        点击后的背景色
textView.setHighlightColor(Color.parseColor("#F33011"));

希望这个能有所帮助
