android:autolink 没效果,Android TextView autoLink web Bug

I have a TextView like this.

android:id="@+id/text_auto_linkify"

android:layout_width="match_parent"

android:layout_height="wrap_content"

android:autoLink="web"

android:text="@string/link_text_auto" />

and the @string/link_text_auto" like this

text_auto_linkify: Various kinds

of data that will be auto-linked.\n

1. In this text are some things that are actionable.\n

1.In this text are some things that are actionable.

notice the text, that the first one has space after "1."

and the result is out of my expectation.

[1.In this text are some things that are actionable.] Android thinks it's a hyperlink.

so is there anyone can tell me,why?

my phone is Moto X

and the android version is 5.1.1
