java安卓获取mac_如何使用Java代码获取Android移动终端Mac地址 (How to use Java code to obtain the Mac address of Android ...

要使用Java代码获取Android移动终端的Mac地址，可以使用以下代码：

WifiManager wifiManager = (WifiManager) getApplicationContext().getSystemService(Context.WIFI_SERVICE);
WifiInfo wifiInfo = wifiManager.getConnectionInfo();
String macAddress = wifiInfo.getMacAddress();

首先，获取WifiManager实例，并使用该实例获取WifiInfo对象。然后，通过调用getMacAddress()方法获取Mac地址。

需要注意的是，为了获取Mac地址，应用程序必须声明以下权限：

<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.INTERNET" />

这样就可以在Android移动终端上使用Java代码获取Mac地址了。

how to Adding Functions to NX Menus

To add custom functions to the NX menu, you can use the NXOpen.MenuBar class in NXOpen.NET API. Here is an example code that demonstrates how to add a custom function to the NX menu:

Imports System
Imports NXOpen

Module Module1
    Sub Main()
        ' Get the NX session
        Dim theSession As Session = Session.GetSession()

        ' Get the UI work part
        Dim theUI As UI = theSession.UI
        Dim lw As ListingWindow = theSession.ListingWindow

        ' Get the menu bar
        Dim menuBar As MenuBar = theUI.MenuBar

        ' Get the File menu
        Dim fileMenu As Menu = menuBar.GetMenu("File")

        ' Add a separator to the File menu
        fileMenu.AddSeparator()

        ' Add a custom function to the File menu
        Dim menuItem As MenuItem = fileMenu.AddMenuItem("Custom Function", AddressOf CustomFunction)

        ' Show a message box when the custom function is clicked
        Sub CustomFunction(ByVal item As MenuItem)
            lw.Open()
            lw.WriteLine("Custom function is clicked!")
            lw.Close()
        End Sub

        ' Start the NX message loop to display the menu
        theUI.NXMessageBox.Show("Menu Example", NXMessageBox.DialogType.Information, "Click OK to display the menu")
        theUI.NXMessageBox.GetMessage()

        ' Remove the custom function from the menu
        fileMenu.RemoveMenuItem(menuItem)
    End Sub
End Module

In the above code, we first obtain the NX session and UI work part. Then, we get the MenuBar object using `theUI.MenuBar`. Next, we retrieve the desired menu (e.g., "File") using `GetMenu()` method. We can add a separator using `AddSeparator()` method and add a custom function using `AddMenuItem()` method, specifying the function to be called when the menu item is clicked.

In the example above, the `CustomFunction` is a sub that will be executed when the custom function menu item is clicked. You can customize the behavior of this function to perform your desired actions.

After adding the custom function, we start the NX message loop using `theUI.NXMessageBox.Show()` and `theUI.NXMessageBox.GetMessage()` to display the menu. Finally, we remove the custom function from the menu using `RemoveMenuItem()` method.

Please note that above code is just an example, and you may need to adjust it based on your specific requirements and menu structure in NX.
