點擊 ClickableSpan 的文本時會同時觸發綁定在 TextView 的監聽事件

解決方法：

public class MyLinkMovementMethod implements View.OnTouchListener {
    public static MyLinkMovementMethod getInstance() {
        if (sInstance == null)
            sInstance = new MyLinkMovementMethod();
        return sInstance;
    }
    private static MyLinkMovementMethod sInstance;
    @Override
    public boolean onTouch(View v, MotionEvent event) {
        boolean ret = false;
        CharSequence text = ((TextView) v).getText();
        Spannable stext = Spannable.Factory.getInstance().newSpannable(text);
        TextView widget = (TextView) v;
        int action = event.getAction();
        if (action == MotionEvent.ACTION_UP ||
                action == MotionEvent.ACTION_DOWN) {
            int x = (int) event.getX();
            int y = (int) event.getY();
            x -= widget.getTotalPaddingLeft();
            y -= widget.getTotalPaddingTop();
            x += widget.getScrollX();
            y += widget.getScrollY();
            Layout layout = widget.getLayout();
            int line = layout.getLineForVertical(y);
            int off = layout.getOffsetForHorizontal(line, x);
            ClickableSpan[] link = stext.getSpans(off, off, ClickableSpan.class);
            if (link.length != 0) {
                if (action == MotionEvent.ACTION_UP) {
                    link[0].onClick(widget);
                }
                ret = true;
            }
        }
        return ret;
    }

 holder.content.setOnTouchListener(MyLinkMovementMethod.getInstance());
