Question

I got this dialog snipet:

String message="This will be my message";

    AlertDialog.Builder alt_bld = new AlertDialog.Builder(this);
    alt_bld.setMessage(message)
    .setCancelable(false)
    .setPositiveButton("OK", new DialogInterface.OnClickListener() 
    {
        public void onClick(DialogInterface dialog, int id) 
        {


             ProgressDialog dialog1 = ProgressDialog.show(CombatActivity.this, "Loading", 
                     "Pushing OK...", true);


        Intent i = new Intent();
        i.setClass(MyFirstActivity.this, MySecondActivity.class);
        startActivity(i);
        finish();



        }
    });

    AlertDialog alert = alt_bld.create();
    // Title for AlertDialog
    alert.setTitle("Nyertél.");
    // Icon for AlertDialog
    alert.setIcon(R.drawable.icon);
    alert.show();

My question is:
Should i call .hide() or .dismiss() in any of these ?
The message text will be dynamicly read, and I dont want a separate instance for every shown dialog. I just want only one with updated messages.

So how and when should i call remove or dismiss ?

Answer 1

Yeah, you have to call dismiss() before you call finish(), otherwise the dialog will remain in the background and can cause problem when you try to start other activities.
