Android TextView中連接(link)點擊事件的截取

佈局文件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                 />

這裏autoLink="all"就是連接全部類型的，包括網址，電話，郵件地址什麼的。

Java代碼裏，對連接的事件進行監聽。
