如何更新角标内的数字

[q88qaz]

我是这样子做的： public void updateMagicIndicator() { // 取出MagicIndicator当前的Navigator，强转为CommonNavigator CommonNavigator mCommonNavigator = (CommonNavigator) (myMagicIndicator.getNavigator()); // 进行更新 mCommonNavigator.setAdapter(new CommonNavigatorAdapter() { @Override public int getCount() { // TODO }

        @Override
        public IPagerTitleView getTitleView(Context context, final int index) {
            ColorTransitionPagerTitleView colorTransitionPagerTitleView = new ColorTransitionPagerTitleView(context);
            colorTransitionPagerTitleView.setNormalColor(yourColor);
            colorTransitionPagerTitleView.setSelectedColor(yourColor);
            colorTransitionPagerTitleView.setText(yourTitle);
            colorTransitionPagerTitleView.setTextSize(16);
            colorTransitionPagerTitleView.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View view) {
                    myViewPager.setCurrentItem(index);
                }
            });
           
            //创建一个角标注入到当前Tab
            BadgePagerTitleView badgePagerTitleView = new BadgePagerTitleView(context);
            badgePagerTitleView.setInnerPagerTitleView(colorTransitionPagerTitleView);

            int randNum = (int) (Math.random() * 101);
            String textValue = "";
            if (randNum > 99) {
                textValue = "99+";
            }else {
                textValue = String.valueOf(randNum);
            }
            
            //创建一个TextView来显示角标
            TextView badgeTextView = new TextView(context);
            badgeTextView.setText(statusNum);
            badgeTextView.setTextColor(Color.WHITE);
            badgeTextView.setTextSize(12);
            if (statusNum.length() <= 1) {
                badgeTextView.setTextSize(14);
                badgeTextView.setPadding(12, 1, 12, 1);
            } else if (statusNum.length() <= 2) {
                badgeTextView.setPadding(8, 5, 8, 5);
            } else {
                badgeTextView.setPadding(4, 7, 4, 7);
            }

            badgeTextView.setBackgroundResource(yourBackgroundResource);
            badgePagerTitleView.setBadgeView(badgeTextView);
            //定位角标位于Tab的X，Y轴的位置
            badgePagerTitleView.setXBadgeRule(new BadgeRule(BadgeAnchor.CONTENT_RIGHT, -5));
            badgePagerTitleView.setYBadgeRule(new BadgeRule(BadgeAnchor.CONTENT_TOP, -15));
            badgePagerTitleView.setAutoCancelBadge(false);
            return badgePagerTitleView;
        }

        @Override
        public IPagerIndicator getIndicator(Context context) {
            // TODO
        }
    });
}

请问你这么做可以实现角标更新了吗

    /**
     * 显示角标数量
     *
     * @param index 位置
     * @param count 数量
     */
    protected void showSignCount(int index, int count) {
        BadgePagerTitleView badgePagerTitleView = (BadgePagerTitleView) mCommonNavigator.getPagerTitleView(index);
        TextView tvCount = (TextView) badgePagerTitleView.getBadgeView();
        if (count > 0) {
            boolean beyond = count > 99;
            tvCount.setText(beyond ? "99+" : count + "");
            badgePagerTitleView.setXBadgeRule(new BadgeRule(BadgeAnchor.CONTENT_RIGHT, -UIUtil.dip2px(_mActivity, beyond?20:12)));
            badgePagerTitleView.setYBadgeRule(new BadgeRule(BadgeAnchor.CONTENT_TOP, -UIUtil.dip2px(_mActivity, 3)));
            showView(tvCount);
        } else {
            goneView(tvCount);
        }
    }

一般显示的都是从后台获取的数量，你不可能把它放在那里面直接显示。等数据返回后，再用此方法进行设置。
