如何使TextView中的链接可点击? [英] How to make links in a TextView clickable?

问题描述

我定义了以下TextView:

I have the following TextView defined:

<TextView android:layout_width="wrap_content"
    android:layout_height="wrap_content" android:text="@string/txtCredits"
    android:autoLink="web" android:id="@+id/infoTxtCredits"
    android:layout_centerInParent="true"
    android:linksClickable="true"></TextView>

其中@string/txtCredits是包含<a href="some site">Link text</a>的字符串资源.

where @string/txtCredits is a string resource that contains <a href="some site">Link text</a>.

Android突出显示了TextView中的链接，但它们不响应点击.有人可以告诉我我在做什么错吗?我是否需要在活动中为TextView设置onClickListener，就像这样简单?

Android is highlighting the links in the TextView, but they do not respond to clicks. Can someone tell me what I'm doing wrong? Do I have to set an onClickListener for the TextView in my activity for something as simple as this?

看起来它与我定义字符串资源的方式有关. 这不起作用:

Looks like it has to do with the way I define my string resource. This does not work:

<string name="txtCredits"><a href="http://www.google.com">Google</a></string>

但是确实如此:

<string name="txtCredits">www.google.com</string>

这真是令人讨厌，因为我宁愿显示文本链接，也不显示完整的URL.

Which is a bummer because I would much rather show a text link than show the full URL.

推荐答案

内置于API演示中，我找到了解决问题的方法:

Buried in the API demos I found the solution to my problem:

Link.java:

Link.java:

    // text2 has links specified by putting <a> tags in the string
    // resource.  By default these links will appear but not
    // respond to user input.  To make them active, you need to
    // call setMovementMethod() on the TextView object.

    TextView t2 = (TextView) findViewById(R.id.text2);
    t2.setMovementMethod(LinkMovementMethod.getInstance());

我删除了TextView上的大多数属性，以使其与演示中的内容保持一致.

I removed most of the attributes on my TextView to match what was in the demo.

<TextView
    android:id="@+id/text2"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="@string/txtCredits"/>

那解决了.很难发现和修复.

That solved it. Pretty difficult to uncover and fix.

重要:如果您要呼叫setMovementMethod()，请不要忘记删除autoLink="web".

Important: Don't forget to remove autoLink="web" if you are calling setMovementMethod().
