<textview

android:id="@+id/trineainfo"

android:layout_width="match_parent"

android:layout_height="wrap_content" />

trineainfotv = (textview)activity.findviewbyid(r.id.trineainfo);

trineainfotv.setmovementmethod(linkmovementmethod.getinstance());

spanned text = html.fromhtml("個人首頁:<a href=\"http://www.trinea.cn\"> trinea</a>");

trineainfotv.settext(text);

顯示連結樣式，能點選，touch即點選

trineainfotv.setonclicklistener(new onclicklistener() {

@override

public void onclick(view v) {

uri web = uri.parse("http://www.trinea.cn");

intent i = new intent(intent.action_view, web);

i.setflags(intent.flag_activity_new_task);

activity.startactivity(i);

}

});

顯示連結樣式，能點選。通過手動設定textview的onclicklistener完成點選響應。

android:layout_height="wrap_content"

android:autolink="all" />

trineainfotv.settext("個人首頁:http://www.trinea.cn");

顯示連結樣式，并且能點選(隻響應http://www.trinea.cn部分點選)，不過不支援如下的href形式

trineainfotv.settext("個人首頁:<a href=\"http://www.trinea.cn\"> trinea</a>");

二、不可行方式

顯示連結樣式，不能點選

不顯示連結樣式，不能點選

三、通過源碼分析原因
