Android TextView中鏈接(link)點擊事件的截取

布局文件xml

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

這里autoLink="all"就是鏈接所有類型的，包括網址，電話，郵件地址什么的。

Java代碼里，對鏈接的事件進行監聽。

    @Override

        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的內容(這里給了3個示例鏈接和一個普通字符串)

        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
                /*
                 * 這里是對所有點擊消息的監聽
                 * 可以把鏈接的做標記剔除后監聽非鏈接的點擊
                 * 比如jaycetest區域的點擊
                 */
            }});
    }
    
    private  class JayceSpan extends ClickableSpan {  
          
        private String mSpan;  
  
        JayceSpan(String span) {  
            mSpan = span;  
        }  
  
        @Override  
        public void onClick(View widget) {  
            Log.e("jayce", "span:" + mSpan);
            /*鏈接被點擊
             * 這里可以做一些自己定義的操作
             */
            Intent intent = new Intent(Intent.ACTION_VIEW);
            intent.setData(Uri.parse(mSpan));
            startActivity(intent);
        }  
    }
