Android ListItem的item弹出提醒对话框

我对在这里看到的一个常见问题有一个转折，我很困惑。

我需要的只是列表项的每个子项的对话框。我看到了一个列表项的对话框，但我需要它到列表项的项目。目前，我已经尝试在 getView() 方法内的适配器内执行此操作。

例如：

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

    if (v == null)
    {
        LayoutInflater li = (LayoutInflater) _context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        v = li.inflate(_resourceId, null);
    }

    string description = "howdy Test";

    TextView description = (TextView) v.findViewById(R.id.description);
    description.setText(description );
    description.setOnClickListener(new View.OnClickListener()
    {
        public void onClick(View view)
        {
            AlertDialog.Builder dia = new AlertDialog.Builder(view.getContext());
            dia.setTitle(view.getContext().getResources().getString(R.string.DESCRIPTION_TITLE));
            dia.create();
        }
    });
}

在上面的示例中，它确实进入了 onClick() 方法，但 AlertDialog 没有任何反应。还有其他人尝试过这个吗？有更好的办法吗？更好的是我做错了什么？

谢谢，凯莉

I have a twist on a common question I've seen in here, and I'm puzzled.

What I need is simply a dialog box for each sub item of a list item. I have seen a dialog for a list item, but I need it down to the list item's item. Currently I've tried doing that within the adapter when inside the getView() method.

For example:

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

    if (v == null)
    {
        LayoutInflater li = (LayoutInflater) _context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        v = li.inflate(_resourceId, null);
    }

    string description = "howdy Test";

    TextView description = (TextView) v.findViewById(R.id.description);
    description.setText(description );
    description.setOnClickListener(new View.OnClickListener()
    {
        public void onClick(View view)
        {
            AlertDialog.Builder dia = new AlertDialog.Builder(view.getContext());
            dia.setTitle(view.getContext().getResources().getString(R.string.DESCRIPTION_TITLE));
            dia.create();
        }
    });
}

With that example above, it does go into the onClick() method, but nothing happens with the AlertDialog. Has anyone else tried this? is there a better way? Even better what am I doing wrong?

Thanks,
Kelly

您必须在 dia 对象上调用 show() 方法。此处链接到 Android 文档！

为什么不向列表视图本身添加一个 OnClickListener，而不是向列表视图中的每一项添加一个 OnClickListener？

myListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {

    public void onItemClick(AdapterView parent, View v, int position, long id){

        // Create and show dialog here

    }
});

Instead of adding a OnClickListener to each item in the list view why don't you add one to the listview itself?

myListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {

    public void onItemClick(AdapterView parent, View v, int position, long id){

        // Create and show dialog here

    }
});
