Question

I am newbie in android, in my android app, a main Activity class, which contains a TextView for displaying various status message from other classes. I want to update TextView of main Activity with status values from other classes. There is no direct connection between main activity class and other class. Is it possible in android ? if yes i am not aware to do it. Kindly provide solution to do it

code snippets

//main activity
public class MainMenu extends Activity {

    static String status = "Hello Friends";

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

    TextView tv = (TextView)findViewById(R.id.mytext);
    tv.setText(status);

        MyOtherClass myclass = new MyOtherClass();
        myclass.connect();
}

Other class is not an activity class

 // Other class
 public class MyOtherClass {
  public MyOtherClass(){
  }

   public void connect(){
    String strIP = Mtx.confRead("IPAddress");
    String strPort = Mtx.confRead("Port");

            String msg = "Connecting...";
            // i want to show value of msg varible in Textview of main activity from here
   }

thanking you

Make a status instance field in your main activity

public static status = "initial status";

set it to the TextView

TextView tv = (TextView) findViewById(R.id.youtTextViewId);

tv.setText(status);

and update it using values in other activities when they are called.
