사용자 지정 대화 작성기 충돌 작업

사용자 지정 대화 상자를 사용하여 사용자 지정 대화 상자를 만들려고합니다. 대화 상자가 단추없이 단독으로 작동하고 버튼을 조사한 후에 대화 작성기가 필요했습니다. 나는 이런 식으로 시도 :

Answer 1

이 line 62 가정하면

입니다

AlertDialog.Builder builder = new AlertDialog.Builder(this); 

잘못된 장소에서 대화를 인스턴스화 할 가능성이 있습니다.

AlertDialog.Builder builder; 

로 선언 시도하고 onCreate 방법 내부를 인스턴스화합니다.

protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.beer_page); 

    builder = new AlertDialog.Builder(this); 

    // The rest of your stuff 
    // ... 
}
