On last note :

I finally found the Id of this button : android.R.id.button1.
here's my try (succesfull ):
public void onClick(DialogInterface dialog, int whichButton)
{
Dialog curDialog = (Dialog) dialog;
Button curButton = (Button) curDialog.findViewById
( android.R.id.button1 );
curButton.setText("Coucou");
}

R.string.btn_yes is the string that appear on your button.
Not the id !

findVienwById wants an id !

[android-developers] Re: How to use findViewById() in a dialog

[Al]

setPositiveButton() is for setting the button text and listener. To
use findViewById, you need to set your own custom layout, but this
won't work with AlertDialog.Builder (iirc), you need to use the Dialog
class. Here is some code I use for this in my application:

mDialog = new Dialog(this);
mDialog.setCancelable(true);
mDialog.setContentView(R.layout.dialoginput); //set the custom layout

mBtn_DialogOK = (Button) mDialog.findViewById(R.id.btn_ok); //From our
custom layout
mBtn_DialogOK.setTag(BUTTON_OK_ID);
mBtn_DialogOK.setOnClickListener(this);

Also, findViewById is for R.id., not for Strings.
