问题 I have a Spannable set up on a SearchView for RecyclerView CardViews. If user-entered text is found on the CardView, the text is highlighted in red. When the SearchView line is cleared I would like the CardView text to return to the default Black color. Currently, the text is cleared and the color erroneously remains red.

昨晚研读 ApiDemo 源码至 com.example.android.apis.text.Link 类。首先，看一下其运行效果：　　要给 TextView 加上效果，方式主要有几种：　　第一种，自动应用效果，使用 android:autolink 属性，如：　　Java代码 ? 代码片段，双击复制 01 02 03 04 05 06 07 08 09 10 11 android:id= "@+id/text1" android:layout_width= "match_parent" android:layout_height= "match_parent" android:autoLink= "all" android:text= "@string/link_text_auto" /> 　　第二种，在文本中使用标签，如：　　Java代码 ? 代码片段，双击复制 01 02 03 04 05 06 07 text2: This is some other text, with a link specified via an tag. Use a \"tel:\" URL to dial a phone number 　　第三种，和第二种其实是一样的，只不过将文本改在 JAVA 代码中，如：　　Java代码 ? 代码片段，双击复制 01 02 03 04 05 06
