How to create Context Menu using XML file?
提问by Vasu
I am using XML file for creating Context Menu for my ListView. (Please see below). I also want to set a header for this Context Menu. I read (at http://www.mail-archive.com/[email protected]/msg43062.html)that I can use menu.setHeaderTitle(myContextMenuTitle) in onCreateContextMenu Method. But I need to set this in XML file. How can I accomplish this?
我正在使用 XML 文件为我的 ListView 创建上下文菜单。（请参阅下文）。我还想为此上下文菜单设置标题。我读到（在http://www.mail-archive.com/[email protected]/msg43062.html）我可以在 onCreateContextMenu 方法中使用 menu.setHeaderTitle(myContextMenuTitle) 。但我需要在 XML 文件中设置它。我怎样才能做到这一点？
Following is code for onCreateContextMenu Method, correct me if I am doing anything wrong.. This is my context_menu.xml file:
以下是 onCreateContextMenu 方法的代码，如果我做错了什么，请纠正我.. 这是我的 context_menu.xml 文件：
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="@+id/open" android:title="Open"/>
</menu>
This is my onCreateContextMenuMethod:
这是我的onCreateContextMenu方法：
@Override
public void onCreateContextMenu(ContextMenu menu, View v,
ContextMenuInfo menuInfo) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.context_menu, menu);
super.onCreateContextMenu(menu, v, menuInfo);
}
This is my onCreateMethod:
这是我的onCreate方法：
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
// extras = getIntent().getExtras();
registerForContextMenu(getListView());
...
}

You have to do it the way you are currently doing it.
你必须按照你目前的方式去做。

You can call setHeaderTitle("mytitle")method in ,menu object .
In override method you get menu object as paramrter of OnCreateContextMenumethod.
like this:
您可以setHeaderTitle("mytitle")在 ,menu 对象中调用方法。在覆盖方法中，您将菜单对象作为OnCreateContextMenu方法的参数。像这样：
@Override
public void onCreateContextMenu(ContextMenu menu, View v, ContextMenuInfo menuInfo) {
super.onCreateContextMenu(menu, v, menuInfo);
menu.setHeaderIcon(R.drawable.icon);
menu.setHeaderTitle("Share Menu.");
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.contextmenu, menu);
}
