使用LinkMovementMethod时,我可以在TextView中禁用滚动吗？

Question

我在textView中使用可点击的跨度,只允许部分文本可点击.它工作正常,除了textView向下滚动,这是我不想要的东西.这是因为我使用LinkMovementMethod,如果需要滚动.无论如何取消滚动？

SpannableString ss = "My text [click area] end."

    ClickableSpan clickableSpan = new ClickableSpan() {
        @Override   
        public void onClick(View textView) {
            // My click action
        }
    };

    // Set the span
    String fromString = "text";
    int startClickPos = ss.toString().indexOf(fromString)+fromString.length()+1;
    int endCickPos=startClickPos+ 12;
    ss.setSpan(clickableSpan, startClickPos, endCickPos, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);

    textView.setText(ss);
    textView.setMovementMethod(LinkMovementMethod.getInstance());

我正在使用此代码禁用使用clickableSpan滚动TextView.

public class LinkMovementMethodOverride implements View.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;
}

}

之后,将其作为触摸侦听器应用于目标textview: -

textview.setOnTouchListener(new LinkMovementMethodOverride());
