Android系统默认把网址、电话、地图(geo地址)、邮箱等转换为超链接。
具体请查看android:TextView设置文本样式和超链接
和HTML中的一样,默认超链接都带下划线的,下面的方案可以在TextView中去掉超链接的下划线:
1、重写ClickableSpan类来去掉下划线样式(系统默认使用ClickableSpan来封装超链接)
1
2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 |
//无下划线超链接,使用textColorLink、textColorHighlight分别修改超链接前景色和按下时的颜色
private class NoLineClickSpan extends ClickableSpan { String text ; public NoLineClickSpan ( String text ) { super ( ) ; this. text = text ; } @Override public void updateDrawState (TextPaint ds ) { ds. setColor (ds. linkColor ) ; ds. setUnderlineText ( false ) ; <span style = "color: red;" > //去掉下划线</span> } @Override public void onClick ( View widget ) { processHyperLinkClick (text ) ; <span style = "color: red;" > //点击超链接时调用</span> } } |
2、把超链接文本封装为NoLineClickSpan对象,并添加到TextView中

2 3 4 5 6 |
TextView tv
= findViewById
(R.
id.
tv_click
)
;
SpannableString spStr = new SpannableString ( "萝卜白菜博客-->http://orgcent.com" ) ; ClickSpan clickSpan = new NoLineClickSpan (vo ) ; //设置超链接 spStr. setSpan (clickSpan, 0, str. length ( ), Spanned. SPAN_INCLUSIVE_EXCLUSIVE ) ; tv. append (spStr ) ; tv. setMovementMethod (LinkMovementMethod. getInstance ( ) ) ; |
PS:不用把TextView的属性autoLink设为”all”.
3、设置超链接为可点击状态
1
|
tv.
setMovementMethod
(LinkMovementMethod.
getInstance
(
)
)
;
|
PS:在NoLineClickSpan类中实现onClick()回调方法.
