You can use the UserProfile class to access the current user's BlackBerry Messenger profile and retrieve or change the user's display name, display picture, status, and personal message.

You can retrieve a reference to the current user's profile by invoking the BBMPlatformContext.getUserProfile() method.

The UserProfile class also provides retrieval methods for the current user's UserProfileBox and UserProfileLocation instances.

Retrieve the user's profile

Before you begin: Make sure that you have completed the task, Register your application with the BlackBerry Messenger platform, and that the class that displays the MyUserProfileScreen screen passes in a reference to the BBMPlatformContext object associated with your application.

Import the required classes and interfaces.

import net.rim.blackberry.api.bbm.platform.*;
import net.rim.blackberry.api.bbm.platform.profile.*;
import net.rim.device.api.system.*;
import java.util.*;

Create a class that extends MainScreen. In the constructor for this screen class, pass in the application's associated BBMPlatformContext object.
```
public class MyUserProfileScreen extends MainScreen
{
    public MyUserProfileScreen(BBMPlatformContext platformContext) 
    {

    }
}
```
In the constructor, invoke BBMPlatformContext.getUserProfile() to retrieve a reference to the UserProfile object associated with this BBMPlatformContext. This returned instance is the current user's profile.
```
UserProfile userProfile = platformContext.getUserProfile();
```

In the constructor, retrieve the user's display name, display picture, status, status message, and personal message. Assign these values to the variables.

String displayName = userProfile.getDisplayName();
Bitmap displayPicture = userProfile.getDisplayPicture();
String personalMsg = userProfile.getPersonalMessage();
int status = userProfile.getStatus();
String statusMsg = userProfile.getStatusMessage();

Code sample: Retrieving the user's profile

The following code sample assumes that the class that displayed the MyUserProfileScreen has passed a reference to the application's associated BBMPlatformContext object into the MyUserProfileScreen constructor.

import net.rim.blackberry.api.bbm.platform.*;
import net.rim.blackberry.api.bbm.platform.profile.*;
import net.rim.device.api.ui.container.*;
import java.util.*;

public class MyUserProfileScreen extends MainScreen 
{    
    public MyUserProfileScreen(BBMPlatformContext platformContext) 
    {
        UserProfile userProfile = platformContext.getUserProfile();
        
        String displayName = userProfile.getDisplayName();
        Bitmap displayPicture = userProfile.getDisplayPicture();
        String personalMsg = userProfile.getPersonalMessage();
        int status = userProfile.getStatus();
        String statusMsg = userProfile.getStatusMessage();
    }
}

Update the user's profile

Before you begin: Make sure that you have registered your application with the BlackBerry Messenger platform, and that the class that displays the screen passes in a reference to the BBMPlatformContext object that is associated with this application.

Import the required classes and interfaces.

import net.rim.blackberry.api.bbm.platform.*;
import net.rim.blackberry.api.bbm.platform.profile.*;
import net.rim.device.api.system.*;
import net.rim.device.api.ui.component.*;
import java.util.*;

Create a class that extends MainScreen. In the constructor for this screen class, pass in the BBMPlatformContext object that is associated with this application.
```
public class MyUserProfileScreen extends MainScreen
{
    public MyUserProfileScreen(BBMPlatformContext platformContext) 
    {

    }
}
```
In the constructor, invoke BBMPlatformContext.getUserProfile() to retrieve a reference to the UserProfile object that is associated with BBMPlatformContext. The instance that is returned is the current user's profile.
```
UserProfile userProfile = platformContext.getUserProfile();
```

Invoke UserProfile.setStatus(), and pass in a status and message. A confirmation dialog is displayed when you invoke this method. The following code sample updates the user's status to busy. You can also update the personal message and display picture by invoking setPersonalMessage() and setDisplayPicture(), respectively.

boolean allowed = userProfile.setStatus(Presence.STATUS_BUSY, "I am busy.");

if(! allowed)
    {
        int result = Dialog.ask(Dialog.D_YES_NO, "Would you like CoolApp to stop
                     updating your profile status?");
        if(result == Dialog.YES) 
        {
            // Optional code to prevent the application from asking to update the
            // user's status
        }
     }

Code sample: Updating the user's profile

import net.rim.blackberry.api.bbm.platform.*;
import net.rim.blackberry.api.bbm.platform.profile.*;
import net.rim.device.api.system.*;
import net.rim.device.api.ui.component.*;
import java.util.*;

public class MyUserProfileScreen extends MainScreen 
{    
    public MyUserProfileScreen(BBMPlatformContext platformContext) 
    {
        UserProfile userProfile = platformContext.getUserProfile();
        boolean allowed = userProfile.setStatus(Presence.STATUS_BUSY, "I am busy.");
        if(! allowed) 
        {
            int result = Dialog.ask(Dialog.D_YES_NO, "Would you like CoolApp to
                         stop updating your profile status?");
            if(result == Dialog.YES) 
            {
                // Optional code to prevent the application from asking to update
                // the user's status
            }
         }
    }

}
