i solve it. if someone has the same problem,it maybe can help u. when u setMovementMethod for textview,u also let it scroll. u need prohibit it,so overridde the LinkMovementMethod like this:

public class NoScrollLinkMovementMethod implements OnTouchListener { @Override public boolean onTouch(View v, MotionEvent event) { TextView widget = (TextView) v; Object text = widget.getText(); if (text instanceof Spanned) { Spanned buffer = (Spanned) text;

        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 = buffer.getSpans(off, off,
                    ClickableSpan.class);

            if (link.length != 0) {
                if (action == MotionEvent.ACTION_UP) {
                    link[0].onClick(widget);
                } else if (action == MotionEvent.ACTION_DOWN) {
                    // Selection only works on Spannable text. In our case setSelection doesn't work on spanned text
                    //Selection.setSelection(buffer, buffer.getSpanStart(link[0]), buffer.getSpanEnd(link[0]));
                }
                return true;
            }
        }

    }

    return false;
}

then, setOnTouchListener replace setMovementMethod, it works for me.
