我要显示在超链接点击一个TextView整个字符串。我也不希望看到实际的URL，只是在地方的url显示的文字。关于这个问题阅读其他职位都建议定义类似于这样一个TextView

I want to show the entire string in a textview with the hyperlinks clickable. I also don't want to see the actual url, just the text that's shown in place of the url. Reading other posts on the subject they all suggest defining a textview similar to this

<TextView
            android:id="@+id/tvArtistOverview"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_margin="10dp"
            android:autoLink="web"
            android:linksClickable="true" />

和TextView的的SetMovementMethod设置为

and setting the SetMovementMethod of the textview to

myTextView.setMovementMethod(LinkMovementMethod.getInstance());

当我按照这些步骤，我的链接是可以点击的，但是我希望他们不会显示。我缺少什么？

When I follow these steps, my links are clickable, however they are not displayed as I wish. What am I missing?

下面是它目前的样子的例子。

Here is an example of how it currently looks.

推荐答案

使用低于code。

TextView tv = ....
tv.setMovementMethod(LinkMovementMethod.getInstance());

    String content = tv.getText().toString();
    List<String> links = new ArrayList<String>();

    Pattern p = Patterns.WEB_URL;
    Matcher m = p.matcher(content);
    while (m.find()) {
        String urlStr = m.group();
        links.add(urlStr);
    }

    SpannableString f = new SpannableString(content);

    for (int i = 0; i < links.size(); i++) {
        final String url = links.get(i);

        f.setSpan(new InternalURLSpan(new OnClickListener() {
            public void onClick(View v) {
                Context ctx = v.getContext();
                String urlToOpen = url;
                if (!urlToOpen.startsWith("http://") || !urlToOpen.startsWith("https://"))
                    urlToOpen = "http://" + urlToOpen;
                openURLInBrowser(urlToOpen, ctx);
            }
        }), content.indexOf(url), content.indexOf(url) + url.length(), Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
    }

    tv.setText(f);
