안드로이드 퀴즈 논리/코딩

Question

나는 actionscript를 사용하여 퀴즈를 만들었습니다. 나는 안드로이드 (완전한 초보자)에서 퀴즈에 대한 작업을 시작했고, 논리를 중심으로 내 머리를 쓰지 않는 액션 스크립트를 따라 갔다.

나는 change_question 기능, 특히 첫 번째 덩어리를 접근하는 방법을 모르겠어요. 이하.

function change_question(){ 
    if(tick.visible){ 
    right_answers++; 
    } 
    if(cross.visible){ 
    wrong_answers++; 
    } 
    if(qno==questions.length){ 
     gotoAndPlay(2); 
    }else{ 
    tick.visible=false; 
    cross.visible=false; 
    rnd1=Math.ceil(Math.random()*3); 
    rnd2=Math.ceil(Math.random()*questions.length)-1; 
    q.text=questions[rnd2]; 
    if(questions[rnd2]=="x"){ 
    change_question(); 
    } 
    questions[rnd2]="x"; 
    enable_disable(1); 

모든 안내를 받으실 수 있습니다. 미리 감사드립니다.

나는 (내가 전혀 논리적 인 순서로, 가서 내가이 답변으로 그들을 편집 할 수 있습니다) 당신에게 몇 점을 줄 것이다.

• 당신이 당신의 개인 rnd의 정의

  는 회원 TextView[]에 질문을 설정합니다. 이 방법을 사용하면 많은 사람들이 findViewById()을 호출하는 방법을 알지 못하며 java에서 enhanced for-loop을 알게되면 많은 코드가 저장됩니다.

• shade1.addEventListener(MouseEvent.CLICK, ButtonAction2);는 setVisibilty() 및 getVisibility(), 당신은 단순히 다른 요소에 온 클릭 이벤트를 사용하지 않으려면 당신을 이동하는 데 도움이 setEnabled(true | false)

희망을 사용할 수 있습니다 발견

shade1.setOnClickListener(new OnClickListener() { 
    public void onClick(View view) { 
     buttonAction2(); 
    } 
}; 

될 것입니다 을 따라서.
