Just use focus on positive

add this line in your positive button

 alertDialog.setOnShowListener(new DialogInterface.OnShowListener(){

        @Override
        public void onShow(DialogInterface dialog) {

            Button positive= alertDialog.getButton(AlertDialog.BUTTON_POSITIVE);
            positive.setFocusable(true);
            positive.setFocusableInTouchMode(true);
            positive.requestFocus();
        }
    });

For Kotlin(in Android)

       AlertDialog.Builder(this)
            .setTitle("Title")
            .setMessage("Do you want to cancel the Transaction?")
            .setCancelable(false)
            .setPositiveButton(
                "Yes"
            ) { dialog: DialogInterface, which: Int ->
                dialog.dismiss()
                // for sending data to previous activity use
                // setResult(response code, data)
                finish()
            }
            .setNegativeButton(
                "No"
            ) { dialog: DialogInterface, which: Int -> dialog.dismiss() }
            .show()
