没有上下文菜单显示为可扩展列表视图的孩子 [英] No context menu is shown for child of expandable listview

问题描述

我有我的活动可扩展列表视图。我想，以示对孩子的一个文本菜单。基本上我知道如何做到这一点，但实施contextMenu当它从来没有显示出来为孩子的意见。只是在组视图长的点击和我没有找到这种现象的原因。任何想法可能？
在此先感谢！

I'm having an expandable listview in my activity. I want to show a contextmenu for the childs. Basically I know how to do this, but when implementing the contextmenu it never shows up for the child views. Just for long clicks on the group view and I didn't find the reason for this behavior. Any ideas maybe? Thanks in advance!

设置的扩展列表视图：

public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
    super.onActivityCreated(savedInstanceState);
    View v = inflater.inflate(R.layout.listed_data, container, false);
    parser = new SvwXmlparser("a", getSherlockActivity());
    elv = (ExpandableListView) v.findViewById(R.id.svwexplist);
    return v;


}
public void onActivityCreated(Bundle savedInstanceState)
{
    super.onActivityCreated(savedInstanceState);
    registerForContextMenu(elv);
    infos = parser.parse();
    showData();
}
public void showData()
{
    adapter = new SvwInfoAdapter(getSherlockActivity(), infos);
    elv.setAdapter(adapter);
}

适配器：

public Object getChild(int groupPos, int childPos) {
    return children.get(groupPos).get(childPos);
}

public long getChildId(int groupPos, int childPos) {
    return childPos;
}

public View getChildView(int groupPosition, int childPosition, boolean isLastChild,
        View convertView, ViewGroup parent) {
    //TODO:modify
    String player = (String)getChild(groupPosition, childPosition);
     if (convertView == null) {
            LayoutInflater infalInflater = (LayoutInflater) context
                    .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            convertView = infalInflater.inflate(R.layout.svw_team_child_layout, null);
        }
     convertView.setFocusableInTouchMode(true);
     TextView players = (TextView) convertView.findViewById(R.id.tvteamChild);
     /*if(childPosition> 1)
     {
         players.setText((childPosition-1) + ". " + player);
     }
     else
     {
         players.setText(player);
     }*/
     players.setText(player);
    return convertView;
}

public int getChildrenCount(int groupPos) {
    return children.get(groupPos).size();
}

public boolean isChildSelectable(int arg0, int arg1) {
    return true;
}

创建文本菜单：

public void onCreateContextMenu(ContextMenu menu, View v, ContextMenuInfo menuInfo)
{
    super.onCreateContextMenu(menu, v, menuInfo);

    ExpandableListContextMenuInfo info = (ExpandableListContextMenuInfo) menuInfo;
    int groupPos = ExpandableListView.getPackedPositionGroup(info.packedPosition);
    int childPos = ExpandableListView.getPackedPositionChild(info.packedPosition);
    int type = ExpandableListView.getPackedPositionType(info.packedPosition);
    Toast toas =Toast.makeText(getSherlockActivity(), groupPos + " - " + childPos, Toast.LENGTH_LONG);
    toas.show();

的吐司显示对于每个组，但不为孩子...

The toast shows for every group but not for the children...

推荐答案

我终于理解了它...它不工作设置可触摸=在XML假的。调用适配器的getView的方法为组和子视图setTouchable（假）后，一切工作像预想的那样。

I finally figured it out... It's not working to set touchable=false in the xml. After calling setTouchable(false) in the adapter's getView-methods for group and child view, everything is working as supposed.
