仿照微信的评论功能，点击评论的时候背景设置变色，但是拖动的时候背景有时候没有恢复，求大神救救孩子吧。
下面的代码是自定义clickspan

public class MyClickableSpan extends ClickableSpan {

    private onTextClickListener mListener;



    public MyClickableSpan(onTextClickListener listener) {

        this.mListener = listener;

    }



    @Override

    public void onClick(View widget) {

        mListener.textClick(widget);

    }



    @Override

    public void updateDrawState(TextPaint ds) {

        super.updateDrawState(ds);

        mListener.setStyle(ds);

    }

}

下面的代码是LinkMovementMethod

public class MyLinkMovementMethod extends LinkMovementMethod {



    private static LinkMovementMethod sInstance;



    public static MovementMethod getInstance() {

        if (sInstance == null)

            sInstance = new MyLinkMovementMethod();



        return sInstance;

    }



    @Override

    public boolean onTouchEvent(TextView widget, Spannable buffer, MotionEvent event) {



        int action = event.getAction();



        if (action == MotionEvent.ACTION_UP ||

                action == MotionEvent.ACTION_DOWN ||

                action == MotionEvent.ACTION_MOVE) {



            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) {

                switch (action){

                    case MotionEvent.ACTION_UP:

                        link[0].onClick(widget);



                        buffer.setSpan(new BackgroundColorSpan(Color.TRANSPARENT),

                                buffer.getSpanStart(link[0]), buffer.getSpanEnd(link[0]),

                                Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);



                        Selection.removeSelection(buffer);

                        break;

                    case MotionEvent.ACTION_DOWN:

                        buffer.setSpan(new BackgroundColorSpan(Color.GRAY),

                                buffer.getSpanStart(link[0]), buffer.getSpanEnd(link[0]),

                                Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);



                        Selection.setSelection(buffer,

                                buffer.getSpanStart(link[0]),

                                buffer.getSpanEnd(link[0]));

                        break;

                    case MotionEvent.ACTION_MOVE:

                        buffer.setSpan(new BackgroundColorSpan(Color.TRANSPARENT),

                            buffer.getSpanStart(link[0]), buffer.getSpanEnd(link[0]),

                            Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);



                        Selection.removeSelection(buffer);

                        break;

                }

                return false;

            } else {

                Selection.removeSelection(buffer);

                return false;

            }

        }

//        return super.onTouchEvent(widget, buffer, event);

        return false;

    }
