android textview 自动链接网址 修改默认点击事件
1 修改XML文件即可，android:autoLink="web"
[code=xml"]
<TextView
        android:id="@+id/text_view"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:autoLink="all"
        android:text="@string/hello" />

autoLink有好几种类型:web phone all等。
