내 alertdialog에 문제가 있습니다

Question

두 가지 작업을 만들었습니다. 첫 번째 작업에는 구인 정보가 포함되어 있으며 다음 작업 제안은이 작업에 대한 것입니다. 작업 신청 후, 경고 대화 상자가 나타나 작업의 성공 여부를 확인합니다. 그러나이 경고 대화 상자는 값이없는 작업 세부 정보의 관점에서 나타납니다! 어떻게 관리 할 수 ​​있습니까 ??

가 경고 대화 상자에 대해 다음 사용 이 활동 1입니다. 요구 사항을 이해하는 데 필요한 세부 정보를 제공하십시오.

public void Alert(String text, String title) 
    { 
     AlertDialog dialog=new AlertDialog.Builder(context).create(); 
     dialog.setTitle(title); 
     dialog.setMessage(text);
