Jin Yong, the first martial arts sword! The yundun is an exclusive game of the World. After the age of 40, the yundun is the hero of the artifact.

In this section, we will learn how to use the Android platform "text" textview to navigate to an activity. The following example shows the scenario:

I. Key technical points of the case

1. Android. Text. spannablestring: provides an overall text that is immutable, but supports local objects (marked by it) that can be appended or separated.

2. spannablestring class setspan (...): Set the link address, link display content, and additional content application effect.

3. spanned. span_exclusive_exclusive: the new characters in the front-end and back-end of the current text do not use the current display effect.

4. Android. Text. method. linkmovementmethod: Provides the hyperlink function. When textview needs this function, you can introduce the instance of this class.
