小编Shi*_*ons的帖子

我正在使用自定义适配器并在getView()方法上添加此代码:

final ImageView popupMenu = (ImageView) v.findViewById(R.id.popupMenu);
    popupMenu.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View view) {
            popupMenu.setImageResource(R.drawable.ic_popup_menu_selected);
            PopupMenu popup = new PopupMenu(context, view);
            popup.getMenuInflater().inflate(R.menu.popup, popup.getMenu());
            popup.setOnDismissListener(new PopupMenu.OnDismissListener() {
                @Override
                public void onDismiss(PopupMenu pm) {
                    popupMenu.setImageResource(R.drawable.ic_popup_menu);
                }
            });
            popup.show();
        }
});

但我得到这个错误: java.lang.RuntimeException: Failed to resolve attribute at index 6

相同的代码适用于ListItemClick(),但它没有意义,因为它需要单击一次设置并再次单击以触发PopupMenu.
