Question

First of all please bear with me because I’m new in Android.

I would like to write an application that can pop up a dialog box if a condition is met

example :

public class TestMax {

       public void main(String[] args) {
          int i = 5;
          int j = 5;
          int sum = i + j;

                   if (sum == 10) {


                // alert dialog box will appear and show the message -  "Answer is 10"

               }


    }

Appreciate your help. Thank you.

Add this when your condition is met:

AlertDialog alertDialog = new AlertDialog.Builder(this).create();
alertDialog.setTitle("Title");
alertDialog.setMessage("Message");
alertDialog.setButton("OK", new DialogInterface.OnClickListener() {
  public void onClick(DialogInterface dialog, int which) {
  // TODO Add your code for the button here.   }
});
// Set the Icon for the Dialog
alertDialog.setIcon(R.drawable.icon);
alertDialog.show();
