Question

我有一个新的需要点击的东西列表但是这个没有用。永远不会调用onListItemClick。我的应用程序中有另一个已按预期工作，我无法弄清楚有什么区别。我发现可能存在一些冲突，因为他们都使用提供的@id / android：列表，但他们在不同的活动中，我没有发现其他人抱怨同样的问题所以我不确定。< / p>

这是一堆代码。我很感激任何建议。

工作：

@Override
protected void onListItemClick(ListView l, View v, int position, long id)
{
    super.onListItemClick(l, v, position, id);

    // get the item that was clicked
    v_ProjectInvestigatorSiteContact project = (v_ProjectInvestigatorSiteContact) this.getListAdapter().getItem(
            position);

    Intent myIntent = new Intent(this, Details.class);

    myIntent.putExtra(res.getString(R.string.project), project);

    startActivity(myIntent);
}// onListItemClick

不工作：

    @Override
protected void onListItemClick(ListView l, View v, int position, long id)
{
    super.onListItemClick(l, v, position, id);

    // get the item that was clicked
    final v_SitePeople vSitePeople = (v_SitePeople) this.getListAdapter().getItem(
            position);

    AlertDialog.Builder builder = new AlertDialog.Builder(Share.this);
    builder.setTitle(res.getString(R.string.forgot_password_check_dialog_title))
            .setMessage(res.getString(R.string.share_check_dialog_text))
            .setPositiveButton(res.getString(R.string.send), new DialogInterface.OnClickListener()
            {
                @Override
                public void onClick(DialogInterface dialog, int which)
                {
                    sendShareEmail(vSitePeople);
                }
            }).setNegativeButton(res.getString(R.string.cancel), new DialogInterface.OnClickListener()
            {
                @Override
                public void onClick(DialogInterface dialog, int which)
                {
                    // cancelled, so do nothing
                }
            });
    AlertDialog msgBox = builder.create();
    msgBox.show();
}// onListItemClick

非常感谢你的帮助。

根据要求提供更多代码。

使用setListAdapter：

    public void updateDisplay(ArrayList<v_ProjectInvestigatorSiteContact> vProjectInvestigatorSiteContactList)
{
    if (fullAdapter != null)
    {
        if (fullAdapter.isEmpty())
        {
            fullAdapter = new ProjectAdapter(this, R.layout.row, vProjectInvestigatorSiteContactList);
            fullAdapter = reOrder(fullAdapter);
            setListAdapter(fullAdapter);
        }
        else
        {
            filteredAdapter = new ProjectAdapter(this, R.layout.row, vProjectInvestigatorSiteContactList);
            filteredAdapter = reOrder(filteredAdapter);
            setListAdapter(filteredAdapter);
        }
    }
    else
    {
        fullAdapter = new ProjectAdapter(this, R.layout.row, vProjectInvestigatorSiteContactList);
        fullAdapter = reOrder(fullAdapter);
        setListAdapter(fullAdapter);
    }

Answer 1

我明白了。我没有发布相关代码，或者我相信你们会为我发现它。

我从一段代码中复制了一个非工作适配器，如果viewType为0，则返回false。由于我的第二个列表只有一个类型，所以一切都被禁用了。

谢谢大家的努力。我很抱歉我没有给你正确的代码。

使用@id / android：list的Android多个列表
