java - Androidクイズのロジック/コーディング

Question

actionscriptを使用してクイズを作成しました。ロジックに頭を悩ませることなく、アクションスクリプトに従って、Android（完全な初心者）でクイズに取り組み始めました。

change_question関数、特にこの最初のチャンクにアプローチする方法がわかりません。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);

任意のガイダンスをいただければ幸いです。前もって感謝します。

これが私のAndroidコードです！

これは、ロジックを支援するために使用し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(rnd1==2){opt1.text=answers[rnd2][2];opt2.text=answers[rnd2][0];opt3.text=answers[rnd2][1];opt4.text=answers[rnd2][3];} 
  if(rnd1==3){opt1.text=answers[rnd2][1];opt2.text=answers[rnd2][2];opt3.text=answers[rnd2][0];opt4.text=answers[rnd2][3];} }} 

  function enable_disable(a){ 
  if(a==0)   {shade1.mouseEnabled=false;shade2.mouseEnabled=false;shade3.mouseEnabled=false;shade4.mouseEnabled=false;} 
  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); 
shade2.addEventListener(MouseEvent.CLICK, ButtonAction3); 
shade3.addEventListener(MouseEvent.CLICK, ButtonAction4);
shade4.addEventListener(MouseEvent.CLICK, ButtonAction5);

 function ButtonAction2(eventObject:MouseEvent){enable_disable(0);if(rnd1==1){      tick.visible=true;tick.y=shade1.y}else{cross.visible=true;cross.y=shade1.y}}

私はあなたにいくつかのポイントを与えます（私は行くにつれて、論理的な順序ではなく、これらをこの答えに編集します）。

個人を定義するときrndは、メンバーに質問を設定しますTextView[]。このように、多くの呼び出しを行う必要はありません。Javaで拡張されたforループfindViewById()を理解すれば、多くのコードを節約できます。

shade1.addEventListener(MouseEvent.CLICK, ButtonAction2);となります

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

setVisibilty()とを見つけましたgetVisibility()。他の要素でonClickイベントを無効にするだけの場合は、setEnabled(true | false)

それがあなたを動かすのに役立つことを願っています。
