仿QQ 小红点实现

第一步

implementation 'q.rorbin:badgeview:1.1.3' 导入

 

第二步

@Override
    protected void convert(BaseViewHolder helper, String item) {
            helper.setText(R.id.text,"一二三"+item);

        Badge badge = new QBadgeView(mContext).bindTarget(helper.getView(R.id.text)).setBadgeNumber(5);
        badge.setBadgeGravity(Gravity.CENTER | Gravity.END);
        badge.setBadgeTextSize(14, true);
        badge.setBadgePadding(6, true);
        badge.setOnDragStateChangedListener(new Badge.OnDragStateChangedListener() {
            @Override
            public void onDragStateChanged(int dragState, Badge badge, View targetView) {
                if (dragState == STATE_SUCCEED) {
                    Toast.makeText(mContext, "哇", Toast.LENGTH_SHORT).show();
                }
            }
        });
    }

完成 我用的是万能适配器

没有办法就是这么简单
