알림 대화 상자는 다음과 같이 builder를 이용하여 설정해주고
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("안내");
builder.setMessage("종료하시겠습니까?");
builder.setIcon(android.R.drawable.ic_dialog_alert);
builder.setPositiveButton("예", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialogInterface, int i) {
Snackbar.make(text, "예 버튼이 눌렸습니다.", Snackbar.LENGTH_LONG).show();
}
});
builder.setNegativeButton("아니오", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialogInterface, int i) {
Snackbar.make(text, "아니오 버튼이 눌렸습니다.", Snackbar.LENGTH_LONG).show();
}
});
마지막에
AlertDialog alertDialog = builder.create();
alertDialog.show();
create하여 show해주면 된다.
