Basic Components of Android 01-textview

Textview is one of our most commonly used components. It is mainly used to display text content. I believe you are very familiar with it, therefore, common attributes (such as setting the font size, color, text location, and so on) are not described here. The following lists the interesting attributes of textview, which I hope will help you.

1. Set click link
Android: autolink
This attribute is used to set whether the text is displayed as a clickable link when the text is URL link, email, phone number, or map. Optional values: none (common text, default value)/Web (URL, click to open the page)/email (email, click to send an email)/phone (phone number, click Open dialing Interface)/MAP/All.
