感謝各位熱情網友的回答，我已經找到相關的答案了。具體如下：

1. 注意android:autoLink="web"

   <TextView  
       android:id="@+id/text_view"  
       android:layout_width="fill_parent"  
       android:layout_height="wrap_content"  
       android:autoLink="web"  
       android:text="@string/hello" />  

   2.重寫url的點擊事件

public class MainActivity extends Activity {

  
    TextView tv;  
  
    @Override  
    protected void onCreate(Bundle savedInstanceState) {  
        super.onCreate(savedInstanceState);  
        setContentView(R.layout.activity_main);  
        tv = (TextView) findViewById(R.id.tv);  
        CharSequence text = tv.getText();  
        if (text instanceof Spannable) {  
            int end = text.length();  
            Spannable sp = (Spannable) text;  
            URLSpan urls[] = sp.getSpans(0, end, URLSpan.class);  
            SpannableStringBuilder style = new SpannableStringBuilder(text);  
            style.clearSpans();  
            for (URLSpan urlSpan : urls) {  
                MyURLSpan myURLSpan = new MyURLSpan(urlSpan.getURL());  
                style.setSpan(myURLSpan, sp.getSpanStart(urlSpan),  
                        sp.getSpanEnd(urlSpan),  
                        Spannable.SPAN_EXCLUSIVE_INCLUSIVE);  
  
            }  
            tv.setText(style);  
        }  
    }  
  
    private class MyURLSpan extends ClickableSpan {  
  
        private String url;  
  
        public MyURLSpan(String url) {  
            this.url = url;  
        }  
  
        @Override  
        public void onClick(View arg0) {  
            startActivity(new Intent(WXEntryActivity.this,RegisterActivity.class));  
        }  
  
    }  
  
}  

3.上面兩步完美的解決了網站連結標高亮顯示並且有下劃線，點擊時，可以在跳到確定的Activity中

最後再次感謝各位的回答，更加感謝網友@小谷xg 評論中給出這方面的博客參考，學習到了很多很多。

需要這麼繞彎嗎？直接textView設定clickable="true",然後設定textview.setOnclickListener點擊事件，跳轉就可以,textview.getText取得網址

繼承ClickableSpan重写onClick方法

我之前這麼寫過，你看有沒有幫助

public class MainActivity extends ActionBarActivity {
    private TextView textView;
    static Context ctx = null;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        textView = (TextView) findViewById(R.id.tv);
        ctx = this;
        textView = (TextView) findViewById(R.id.tv);
        String htmlLinkText = "<a href=\"" + "http:" + "/" + "/"
                + "www.baidu.com\"><u>我的CSDN博客 </u></a>";
        textView.setText(Html.fromHtml(htmlLinkText));
        textView.setMovementMethod(LinkMovementMethod.getInstance());
        CharSequence text = textView.getText();
        if (text instanceof Spannable) {
            int end = text.length();
            Spannable sp = (Spannable) textView.getText();
            URLSpan[] urls = sp.getSpans(0, end, URLSpan.class);
            SpannableStringBuilder style = new SpannableStringBuilder(text);
            style.clearSpans();
            for (URLSpan url : urls) {
                MyURLSpan myURLSpan = new MyURLSpan(url.getURL());
                style.setSpan(myURLSpan, sp.getSpanStart(url),
                        sp.getSpanEnd(url), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
            }
            textView.setText(style);
        }
    }
    private static class MyURLSpan extends ClickableSpan {
        private String mUrl;
        MyURLSpan(String url) {
            mUrl = url;
        }
        @Override
        public void onClick(View widget) {
            Toast.makeText(ctx, mUrl, Toast.LENGTH_SHORT).show();
        }
    }
}

不要用autolink屬性， 直接設定textview的點擊事件， 含符合條件的String 就除非對應的事件：例如呼叫某個activity

需求描述：
1、樓主需要對網站連結標有下劃線
2、樓主希望點擊時，跳到確定的Activity中

群主找到解決方法了嗎？我也遇到這樣的問題了
