Androidクイズロジック/コーディング

Question

私はアクションスクリプトを使用してクイズを作成しました。私はアンドロイド（完全な初心者）のクイズに取り組み始め、ロジックの周りに頭を浮かべるようなアクションスクリプトに従っています。

私はchange_question関数にアプローチする方法、特にこの最初のチャンクを知りません。以下。

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); 

任意の指針が認められます。前もって感謝します。

これは私がロジックを支援するために使用されているアクションスクリプトモデルです。

var qno=0;var rnd1; var rnd2; 
    tick.visible=false;cross.visible=false; 
    var right_answers=0;var wrong_answers=0; 

    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); 

    if(rnd1==1){opt1.text=answers[rnd2][0];opt2.text=answers[rnd2][1];opt3.text=answers[rnd2][2];opt4.text=answers[rnd2][3];}

    if(a==1){shade1.mouseEnabled=true;shade2.mouseEnabled=true;shade3.mouseEnabled=true;shade4.mouseEnabled=true;}} 

change_question(); 

next_b.addEventListener(MouseEvent.CLICK, ButtonAction1); 
function ButtonAction1(eventObject:MouseEvent) {qno++;change_question();} 

shade1.addEventListener(MouseEvent.CLICK, ButtonAction2);

Answer 1

私はあなたにいくつかのポイントを与えます（私はこの答えに私は絶対に論理的な順序で編集しません）。

• あなたは、個々のrnd Sを定義

  は、メンバーTextView[]であなたの質問を設定します。このようにして、多くの人がfindViewById()を呼び出すのではなく、javaのenhanced for-loopを知ることができれば、多くのコードを節約できます。

• shade1.addEventListener(MouseEvent.CLICK, ButtonAction2);あなたはsetVisibilty()とgetVisibility()、あなたは、単に他の要素上のonClickイベントを無効にしたい場合は、あなたを動かすことができますsetEnabled(true | false)

希望を使用することができますを発見した

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

になります一緒に。
