Android学习—— TextView ClickableSpan 点击链接事件 改超链接颜色

	private SpannableStringBuilder dealWeiboContent(String weiboContent,
			TextView textView) {
		Pattern pattern = Pattern
				.compile("((http://|https://){1}[\\w\\.\\-/:]+)|(#(.+?)#)|(@[\\u4e00-\\u9fa5\\w\\-]+)");
		temp = weiboContent;
		Matcher matcher = pattern.matcher(temp);
		List<String> list = new LinkedList<String>();
		while (matcher.find()) {
			if (!list.contains(matcher.group())) {
				temp = temp.replace(
						matcher.group(),
						"<a href=\"" + matcher.group() + "\">"
								+ matcher.group() + "</a>");
				/*temp = temp.replace(
						matcher.group(),
						"<font color='#365C7C'><a href='" + matcher.group() + "'>"
								+ matcher.group() + "</a></font>");*/
			}
			list.add(matcher.group());
		}
		textView.setText(Html.fromHtml(temp));
		System.out.println("temp" + temp);
		textView.setMovementMethod(LinkMovementMethod.getInstance());
		CharSequence text = textView.getText();
		if (text instanceof Spannable) {
			int end = text.length();
			Spannable sp = (Spannable) textView.getText();
			URLSpan[] urls = sp.getSpans(0, end, URLSpan.class);
			SpannableStringBuilder style = new SpannableStringBuilder(text);
			style.clearSpans();
			for (URLSpan url : urls) {
				style.setSpan(((ThinksnsWeiboContent) activityContent)
						.typeClick(url.getURL()), sp.getSpanStart(url), sp
						.getSpanEnd(url), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
			}
			return style;
		}
		return null;
	}

自定义方法

public ClickableSpan typeClick(final String value) {
		char type = value.charAt(0);
		switch (type) {
		case '@':
			return new ClickableSpan() {
				@Override
				public void onClick(View widget) {
					// TODO Auto-generated method stub
					String uname = "";
					uname = value.substring(1, value.length());
					System.out.println("weiboContent---uanme---"+uname);
					
				}
				
				@Override
				public void updateDrawState(TextPaint ds) {
					 	ds.setColor(Color.argb(255, 54, 92, 124));
				        ds.setUnderlineText(true);
				}
			};

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）

//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); //去掉下划线
	}

	@Override
	public void onClick(View widget) {
	    processHyperLinkClick(text); //点击超链接时调用
	}
}

2、把超链接文本封装为NoLineClickSpan对象，并添加到TextView中

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

tv.setMovementMethod(LinkMovementMethod.getInstance());

PS:在NoLineClickSpan类中实现onClick()回调方法.
