android - 适配器 getView() 内的 PopupMenu 不起作用

Question

我正在使用自定义适配器并在 getView() 方法上添加以下代码:

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();
        }
});

但我收到此错误: java.lang.RuntimeException:无法解析索引 6 处的属性

相同的代码适用于ListItemClick()，但在那里没有意义，因为需要单击一次才能设置，然后再次单击才能触发 PopupMenu。

Answer 1

通过以下导入，我总是遇到错误:

import android.support.v7.widget.PopupMenu;

它可以与以下导入一起正常工作:

import android.widget.PopupMenu;
