textview自定义跳转链接

设置方式 ,主要是遍历html中的url,然后加一个自定义的跳转

    private void setTextLink(String rule) {
        if(TextUtils.isEmpty(rule)){
            return;
        }
        mTips.setText(Html.fromHtml(rule));
        mTips.setMovementMethod(LinkMovementMethod.getInstance());
        CharSequence text = mTips.getText();
        if (text instanceof Spannable) {
            int end = text.length();
            Spannable spannable = (Spannable) mTips.getText();
            URLSpan[] urlSpans = spannable.getSpans(0, end, URLSpan.class);
            if (urlSpans.length == 0) {
                return;
            }

            SpannableStringBuilder spannableStringBuilder = new SpannableStringBuilder(text);
            spannableStringBuilder.clearSpans();//注意,必须先清除默认span,否则不会生效
            // 循环遍历并拦截 所有http://开头的链接
            for (URLSpan uri : urlSpans) {
                String url = uri.getURL();
                if (url.indexOf("http://") == 0 || url.indexOf("https://") == 0) {
                    CustomUrlSpan customUrlSpan = new CustomUrlSpan(getActivity(),url);
                    spannableStringBuilder.setSpan(customUrlSpan, spannable.getSpanStart(uri),
                            spannable.getSpanEnd(uri), Spannable.SPAN_INCLUSIVE_EXCLUSIVE);
                }
            }
            mTips.setText(spannableStringBuilder);
        }
    }

自定义的span

public class CustomUrlSpan extends ClickableSpan {
    private Context context;
    private String url;
    public CustomUrlSpan(Context context,String url){
        this.context = context;
        this.url = url;
    }

    @Override
    public void onClick(View widget) {
　　　　　　//TODO 自定的跳转写这里
    }
}
