申请文本菜单自定义标题 [英] Applying a custom header for ContextMenu

问题描述

我想自定义标题适用于文本菜单 A 的ListView 的。这里的code。

I'm trying to apply a custom header to the ContextMenu of a ListView. Here's the code.

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

    View header = View.inflate(getSherlockActivity(),
            R.id.context_menu_header, (ViewGroup) v);
    TextView title = (TextView) header
            .findViewById(R.id.context_menu_title);
    title.setText(cursor.getString(1));
    menu.setHeaderView(header);

    android.view.MenuInflater inflater = getActivity().getMenuInflater();
    inflater.inflate(R.menu.context_menu, menu);
}

这code不能与资源$ NotFoundException：资源ID＃0x7f050038键入＃12H处无效。在行查看标题= View.inflate（getSherlockActivity（），R.id.context_menu_header，（一个ViewGroup）V）; 。我猜可能是因为参数（ViewGroup中）V 的。我怎样才能解决这个错误得到什么？

This code fails with a Resources$NotFoundException: Resource ID #0x7f050038 type #0x12 is not valid. In the line View header = View.inflate(getSherlockActivity(), R.id.context_menu_header, (ViewGroup) v);. I'm guessing probably because of param (ViewGroup) v. How can I get around this error?

推荐答案

我用 R.id.context_menu_header ，而不是 R.layout .layout_file ，我不得不传递null为View.inflate方法的最后一个参数。

I was using R.id.context_menu_header instead of a R.layout.layout_file and I had to pass null for the last parameter of the View.inflate method.
