java - textview设置属性autolink后，点击网址链接如何捕捉到点击事件或者如何让其跳转到特定的app activity中？

Question

1.现在有一个需求，textview中的字符串，例如：”你好，欢迎来到android世界！http://www.google.com 谷歌是我们的一个好工具“ 点击字符串中的网址不让其跳转到浏览器中，而是能够解析网址中的id，从而跳转到app中特定的activity中。我已经设置了textview的属性autolink="true"
2.目前的问题是，点击网址总是跳转到浏览器！所以我该如何捕捉到点击网址的事件或者如何跳转到指定的Activity中？

Answer 1

感谢各位热情网友的回答，我已经找到相关的答案了。具体如下：

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.重写url的点击事件

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.上面两步完美的解决了网站链接标高亮显示并且有下划线，点击时，可以在跳转到确定的Activity中

最后再次感谢各位的回答，更加感谢网友@小谷xg 评论中给出这方面的博客参考，学习到了很多很多。

需要这么绕弯吗？直接textView设置clickable="true",然后设置textview.setOnclickListener点击事件，跳转就可以,textview.getText获得网址

Answer 3

继承ClickableSpan重写onClick方法

我之前这么写过，你看有没有帮助

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属性， 直接设置textview的点击事件， 含符合条件的String 就除非相应的事件：比如调用某个activity

1、楼主需要对网站链接标有下划线
2、楼主希望点击时，跳转到确定的Activity中

    private void initAgreement(TextView text) {
        text.setClickable(true);
        text.setText(getClickableSpan(text));
        text.setMovementMethod(LinkMovementMethod.getInstance());
    }

    private SpannableString getClickableSpan(TextView textView) {
        View.OnClickListener listener1 = new View.OnClickListener() {
            // 如下定义自己的动作
            public void onClick(View v) {
                Intent intent = new Intent(AboutActivity.this, ProtocalActivity.class);
                intent.putExtra(ProtocalActivity.TITLE_KEY, getString(R.string.user_agreement_content_href1));
                intent.putExtra(ProtocalActivity.CONTENT_URI_KEY, ProtocalActivity.END_USER_LICENSE_AGREEMENT);
                startActivity(intent);
            }
        };
        
        String agreement = textView.getText().toString();
        String h1 = getResources().getString(R.string.user_agreement_content_href1);
        int h1Index = agreement.indexOf(h1);
        SpannableString spanableInfo = new SpannableString(agreement);
        int start1 = h1Index;
        if (start1 != -1) {
            int end1 = start1 + h1.length();
            spanableInfo.setSpan(new Clickable(listener1), start1, end1, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
            spanableInfo.setSpan(new ForegroundColorSpan(Color.parseColor("#28c0c6")), start1, end1,
                    Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
        }
        return spanableInfo;
    }

    class Clickable extends ClickableSpan implements OnClickListener {
        private final View.OnClickListener mListener;

        public Clickable(View.OnClickListener l) {
            mListener = l;
        }

        @Override
        public void onClick(View v) {
            mListener.onClick(v);
        }

        @Override
        public void updateDrawState(TextPaint ds) {
            ds.setUnderlineText(false);
        }
    }
