Android TextView中链接(link)点击事件的截取

布局文件xml

<TextView
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:id="@+id/test_note"
                android:autoLink="all"
                />

这里autoLink="all"就是链接所有类型的，包括网址，电话，邮件地址什么的。

Java代码里，对链接的事件进行监听。

package com.jayce.testlink;

import android.net.Uri;
import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;
import android.text.Spannable;
import android.text.SpannableStringBuilder;
import android.text.style.ClickableSpan;
import android.text.style.URLSpan;
import android.util.Log;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.TextView;

public class TextLinkActivity extends Activity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_text_link);
        TextView tv = (TextView)findViewById(R.id.test_note);
        CharSequence text = tv.getText(); 
        /*
         * 以下是textview的内容(这里给了3个示例链接和一个普通字符串)
         * 13888888888
         * www.google.com
         * test@gmail.com
         * jaycetest
         */
        if (text instanceof Spannable) {  
            int end = text.length();
            Spannable sp = (Spannable) tv.getText();  
            URLSpan[] spans = sp.getSpans(0, end, URLSpan.class);  
            SpannableStringBuilder style = new SpannableStringBuilder(text);  
            style.clearSpans();// should clear old spans  
            for (URLSpan span : spans) {  
                JayceSpan mySpan = new JayceSpan(span.getURL());  
                style.setSpan(mySpan, sp.getSpanStart(span), sp.getSpanEnd(span), Spannable.SPAN_EXCLUSIVE_INCLUSIVE);  
            }  
            tv.setText(style); 
        }
        tv.setOnClickListener(new OnClickListener(){

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                /*
                 * 这里是对所有点击消息的监听
                 * 可以把链接的做标记剔除后监听非链接的点击
                 * 比如jaycetest区域的点击
                 */
            }});
    }
    
    private  class JayceSpan extends ClickableSpan {  
          
        private String mSpan;  
  
        JayceSpan(String span) {  
            mSpan = span;  
        }  
  
        @Override  
        public void onClick(View widget) {  
            Log.e("jayce", "span:" + mSpan);
            /*链接被点击
             * 这里可以做一些自己定义的操作
             */
            Intent intent = new Intent(Intent.ACTION_VIEW);
            intent.setData(Uri.parse(mSpan));
            startActivity(intent);
        }  
    }  

}
