public class MyDailogTestActivity extends Activity {
    /** Called when the activity is first created. */
    String Xvalue,Yvalue;
    TextView TextViewString;    
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        Button ShowDialog = (Button) findViewById(R.id.ShowDialog);
        TextViewString = (TextView) findViewById(R.id.ShowDialogText);      
        ShowDialog.setOnClickListener(new OnClickListener(){
            public void onClick(View arg0) {
                // TODO Auto-generated method stub
                Dialog MyDialog = MyDailog();
                MyDialog.show();
                // I WANT THIS TO EXECUTE AFTER BELOW MENTIONED CODE
                TextViewString.setText(Xvalue + Yvalue);
            }

        });
    }

    private Dialog MyDailog(){
        LayoutInflater factory = LayoutInflater.from(this);
        final View textEntryView = factory.inflate(R.layout.my_dialog, null);
        return new AlertDialog.Builder(MyDailogTestActivity.this)
        .setTitle("Enter Value")
        .setView(textEntryView)
        .setPositiveButton("Oky", new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialog, int whichButton) {
                // THIS TO BE EXECUTE FIRST       
                Xvalue = "This ";
                Yvalue = "and That";                
                /* User clicked OK so do some stuff */
            }
        })
        .setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialog, int whichButton) {
                /* User clicked cancel so do some stuff */
            }
        })
        .create();        
    }

}

Now in this image. When I hit show dialog it carry on executing the next code TextViewString.setText(Xvalue + Yvalue);
in which it shows the value null
now I want it to wait for dialog box to finish code in which Xvalue and Yvalue will have the value “This n That” by this code

Xvalue = "This ";
Yvalue = "and That";

Move this line:

TextViewString.setText(Xvalue + Yvalue);

to your positive button click listener like this:

public void onClick(DialogInterface dialog, int whichButton) {
    // THIS TO BE EXECUTE FIRST    
    Xvalue = "This ";
    Yvalue = "and That";                
    /* User clicked OK so do some stuff */
    TextViewString.setText(Xvalue + Yvalue);
}
