Question

I have following code for alertdialog:

    AlertDialog.Builder helpBuilder = new AlertDialog.Builder(this);
    helpBuilder.setTitle("Options");
    helpBuilder.setMessage("Choose Your Option");

    LayoutInflater inflater = getLayoutInflater();
    View radioButtonLayout = inflater.inflate(R.layout.popuplayout, null);
    byNameRadioButton = (RadioButton) findViewById(R.id.byname);
    byIdRadioButton = (RadioButton) findViewById(R.id.byid);
    helpBuilder.setView(radioButtonLayout);
    helpBuilder.setPositiveButton("Ok",
            new DialogInterface.OnClickListener() {

                public void onClick(DialogInterface dialog, int which) {
                     Toast.makeText(Tab1Activity.this,
                     "Ok button is clicked", Toast.LENGTH_LONG)
                     .show();


                    }


                }
            });

    AlertDialog helpDialog = helpBuilder.create();
    helpDialog.show();

I want to know which radiobutton was clicked when ok OK button is clicked ??

Why don’t you use the default implementation of Dialog with radio buttons which you can find here : Dialogs . You won’t need to write anything extra as code and you will get what you need! : )
Here is the example :

final CharSequence[] items = {"By Score", "By Name", "By Id"};

AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("Options");
builder.setSingleChoiceItems(items, -1, new DialogInterface.OnClickListener() {
    public void onClick(DialogInterface dialog, int item) {
        Toast.makeText(getApplicationContext(), items[item], Toast.LENGTH_SHORT).show();
    }
});
AlertDialog alert = builder.create();
