Question

我被困在某一点上。我想在自定义列表视图中为每个项添加弹出菜单。我已经尝试但它只是在最后一个位置或列表的最后一项弹出。我有理由为什么它会在最后一个位置而不是得到解决方案这里我要添加适配器类

public class InterestLevelAdapterEditable extends BaseAdapter {

    private Activity activity;
    private  TextView level;
    private InterestLevel m;
    private LayoutInflater inflater;
    private List<InterestLevel> interestLevelList;

    public InterestLevelAdapterEditable(Activity activity, List<InterestLevel> interestLevelList) {
        this.activity = activity;
        this.interestLevelList = interestLevelList;
    }

    @Override
    public int getCount() {
        return interestLevelList.size();
    }

    @Override
    public Object getItem(int location) {
        return interestLevelList.get(location);
    }

    @Override
    public long getItemId(int position) {
        return position;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {

        if (inflater == null)
            inflater = (LayoutInflater) activity
                    .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        if (convertView == null)
            convertView = inflater.inflate(R.layout.interest_level_editable, null);


        TextView sports_name = (TextView) convertView.findViewById(R.id.sportsName);
        level = (TextView) convertView.findViewById(R.id.level);

         m = interestLevelList.get(position);

        sports_name.setText(m.getSports_name());

        level.setText(m.getLevel());
        level.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                //Creating the instance of PopupMenu
                PopupMenu popup = new PopupMenu(activity, level);
                //Inflating the Popup using xml file
                popup.getMenuInflater().inflate(R.menu.popup_level, popup.getMenu());

                //registering popup with OnMenuItemClickListener
                popup.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {
                    public boolean onMenuItemClick(MenuItem item) {
                        level.setText(item.getTitle());
                        return true;
                    }
                });

                popup.show();//showing popup menu
            }
        });

        return convertView;
    }

}

我有理由说我必须在点击监听器上传递位置，但不知道我应该如何添加位置或（具有位置的InterestLevel的m对象）。

在PopupMenu -

中创建setOnClickListener() show()以及onClick()之外的

           //Creating the instance of PopupMenu
            final PopupMenu popup = new PopupMenu(activity, level);
            //Inflating the Popup using xml file
            popup.getMenuInflater().inflate(R.menu.popup_level, popup.getMenu());

            //registering popup with OnMenuItemClickListener
            popup.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {
                public boolean onMenuItemClick(MenuItem item) {
                    level.setText(item.getTitle());
                    return true;
                }
            });

level.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {          

            popup.show();//showing popup menu
        }
    });

def self.import(file)
  spreadsheet = open_spreadsheet(file)
  cn = column_names
  header = spreadsheet.row(1)
  (2..spreadsheet.last_row).each do |i|
    rawrow = Hash[[header, spreadsheet.row(i)].transpose]
    cleansedrow = {:properties => {}}
    rawrow.each do |key, value|
      if cn.include?(key)
        cleansedrow[key] = value
      else
        cleansedrow[:properties][key] = value
      end
    end
    record = find_by_id(cleansedrow["id"]) || new
    record.attributes = cleansedrow.to_hash
    record.save!
  end
end

我需要像listview一样的弹出菜单。我尝试使用此代码并且它正确（reference）：

private static final String TITLE = "title";
private static final String ICON = "icon";

private List<HashMap<String, Object>> data = new ArrayList<HashMap<String, 
Object>>();

// Use this to add items to the list that the ListPopupWindow will use
private void addItem(String title, int iconResourceId) {
HashMap<String, Object> map = new HashMap<String, Object>();
map.put(TITLE, title);
map.put(ICON, iconResourceId);
data.add(map);
}

// Call this when you want to show the ListPopupWindow
private void showListMenu(View anchor) {
ListPopupWindow popupWindow = new ListPopupWindow(this);

ListAdapter adapter = new SimpleAdapter(
        this,
        data,
        android.R.layout.activity_list_item, // You may want to use your own cool layout
        new String[] {TITLE, ICON}, // These are just the keys that the data 
uses
        new int[] {android.R.id.text1, android.R.id.icon}); // The view ids 
to map the data to


popupWindow.setAnchorView(anchor);
popupWindow.setAdapter(adapter);
popupWindow.setWidth(400); // note: don't use pixels, use a dimen resource
popupWindow.setOnItemClickListener(myListener); // the callback for when a list item is selected
popupWindow.show();
}

custom layout and work as listview
