#16608 — Accessing a thread

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();
         lanSendThread.start();
...}

__________

File2

public class LanSendThread extends Thread{
	public static Handler lanSendHandler;

     @Override
     public void run(){
            Looper.prepare();

            lanSendHandler = new Handler() {
//stuff}

___________

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.

// 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.
