Question

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();
        }
});

但是我收到了这个错误： 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，因为需要单击一次进行设置并再次单击以触发PopupMenu。

修改：Logcat

Answer 1

通过以下导入，我总是遇到错误：

import android.support.v7.widget.PopupMenu;

使用以下导入工作正常：

import android.widget.PopupMenu;

Answer 2

我这样解决：

在适配器getView（）上添加它：

ImageView popupMenu = (ImageView) v.findViewById(R.id.popupMenu); popupMenu.setTag(getItem(position)); popupMenu.setOnClickListener(MyFragment.popupMenuListener);

这就在MyFragment上：

implements OnClickListener

popupMenuListener = this;

@Override public void onClick(final View view) { view.post(new Runnable() { @Override public void run() { showPopupMenu(view); } }); }

此问题与缺少主题属性有关确保您的应用主题扩展为Theme.AppCompat。

 <style name="AppTheme" parent="@style/Theme.AppCompat" />

PopupMenu里面的适配器getView（）无法正常工作
