File1

public class controller extends Activity {


/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);

final LanSendThread lanSendThread = new LanSendThread();

File2

public class LanSendThread extends Thread{

How do I access the thread lanSendThread from another class in another file?

The same way you'd access it if it were an ArrayList or
a JButton or a File: You save the reference somewhere and dish it out to
interested parties. There must be two or three jillion ways to do this; a few
of them are

- Make `lanSendThread' a public member of the controller
class (poor choice of name, by the way). You may or may
not want to make that member `final'.

- Make `lanSendThread' a private member of the controller
class, and write a public getThread() method to return it.

- Stash the value of `lanSendThread' in a Map or other data
structure, and "publicize" the data structure and/or
accessors for it.

Thanks. It's obvious now!

How do I access the thread lanSendThread from another class in another file?

// execute InParallel.run()
// in parallel to this thread on a new thread.
Thread t = new Thread ( new InParallel() );

// Note we call t.start(), not t.run()
// t.run() would just call run in the ordinary way.

// Get reference to the thread running this
// code right now.
Thread runningNow = Thread.currentThread();

Keep in mind a thread is busy running its own code. Pretty well anything you
run on that thread is going to be highly disruptive.

I still don't see how this solves my problem.
In "main" (controller) I have:

public static Thread txToLanThreadRef;

TxToLanThread txToLanThread = new TxToLanThread();
txToLanThread.start();
txToLanThreadRef = txToLanThread.runningNow;

However, when I try to access it elsewhere, this does not work

controller.txToLanThreadRef.

I need to access the handler in the thread so I can send it a message

 

[markspace]

public static Thread txToLanThreadRef;

Static variables like this are not considered best practice. Consider
some alternatives, including factories, a context object, or some sort
of generic message system.

However, when I try to access it elsewhere, this does not work

controller.txToLanThreadRef.

"Does not work" is a little unspecific. What error/problem do you get?
Can you make a short, complete, compilable example that duplicates the
problem?

It should work, must work, even, according to the Java programming
language. If there's an issue, it must be with the way you are using
it. Please show us.
