1）确保您已将CouponActivity添加为清单文件中的活动。

2）当您从非活动类启动新活动时，需要在启动意图之前添加标记 Intent.FLAG_ACTIVITY_NEW_TASK 。

holder.menuButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {

            Context wrapper = new ContextThemeWrapper(getContext(), R.style.popupMenuStyle);
            PopupMenu popup = new PopupMenu(wrapper,view);

                popup.getMenuInflater().inflate(R.menu.menu_list,popup.getMenu());
            popup.show();

            popup.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {
                @Override
                public boolean onMenuItemClick(MenuItem item) {

                    switch(item.getItemId()){
                        case R.id.share:
                            return true;
                        case R.id.show_coupon:
                            Intent intent = new Intent();
                            intent.setClass(getContext(), CouponActivity.class);
                            Bundle bunde = new Bundle();
                            bunde.putString("coupon","Here is Coupon");
                            intent.putExtras(bunde);
                            intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); //Needed when starting an activity from a non-activity class
                            getContext().startActivity(intent);
                            return true;
                        case R.id.like:
                            return true;
                        default:
                            return true;

                    }

                }
            });

        }
    });
