安卓:textview 超链接 [英] Android: textview hyperlink

问题描述

我知道如果你在 textview 中放置一个链接它会起作用，但如果我想显示例如:

I know that if you put a link in a textview it will work but if I want to display for example:

谷歌堆栈溢出

而不是整个链接(只是标签)我如何使这些链接可点击?

and not the whole link(just the tag) How do i make those links clickable?

推荐答案

你可以有两个单独的 TextViews，如果需要，你可以在你的布局中相应地对齐它们:

You could have two separate TextViews and you could align them accordingly in your layout if needed:

    Text1.setText(
        Html.fromHtml(
            "<a href="http://www.google.com">google</a> "));
    Text1.setMovementMethod(LinkMovementMethod.getInstance());

    Text2.setText(
            Html.fromHtml(
                "<a href="http://www.stackoverflow.com">stackoverflow</a> "));
    Text2.setMovementMethod(LinkMovementMethod.getInstance());

然后如果你想去掉链接下划线".创建一个类:

Then if you want to strip the "link underline". Create a class:

public class URLSpanNoUnderline extends URLSpan {
    public URLSpanNoUnderline(String url) {
        super(url);
    }
    @Override public void updateDrawState(TextPaint ds) {
        super.updateDrawState(ds);
        ds.setUnderlineText(false);
        }
}

然后将此方法添加到您拥有 TextViews 的主 Activity 类中

Then add this method in your main Activity class where you have the TextViews

private void stripUnderlines(TextView textView) {
    Spannable s = new SpannableString(textView.getText());
    URLSpan[] spans = s.getSpans(0, s.length(), URLSpan.class);
    for (URLSpan span: spans) {
        int start = s.getSpanStart(span);
        int end = s.getSpanEnd(span);
        s.removeSpan(span);
        span = new URLSpanNoUnderline(span.getURL());
        s.setSpan(span, start, end, 0);
    }
    textView.setText(s);
}

然后在初始化 TextViews 后调用它(在你的 onCreate 中):

And then just call this after you initialised the TextViews (in your onCreate):

stripUnderlines(Text1);
stripUnderlines(Text2);
