Android TextView中链接(link)点击事件的截取

布局文件xml

1 <TextView

2                 android:layout_width="match_parent"

3                 android:layout_height="match_parent"

4                 android:id="@+id/test_note"

5                 android:autoLink="all"

6                 />

这里autoLink="all"就是链接所有类型的，包括网址，电话，邮件地址什么的。

Java代码里，对链接的事件进行监听。
