Java Android问答逻辑/编码

我用actionscript做了一个测验。我已经开始在android（完全的新手）上做测验，跟随动作脚本，以便让我的头脑绕过逻辑

我不知道如何处理change\u question函数，尤其是第一块。下面

  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);

任何指导都将不胜感激。提前谢谢

              "What car part is considered the biggest performance variable?",

这是我用来帮助理解逻辑的动作脚本模型

  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}}
 function ButtonAction3(eventObject:MouseEvent){enable_disable(0);if(rnd1==2){tick.visible=true;tick.y=shade2.y}else{cross.visible=true;cross.y=shade2.y}}
 function ButtonAction4(eventObject:MouseEvent){enable_disable(0);if(rnd1==3){tick.visible=true;tick.y=shade3.y}else{cross.visible=true;cross.y=shade3.y}}
 function ButtonAction5(eventObject:MouseEvent){enable_disable(0);if(rnd1==4){tick.visible=true;tick.y=shade4.y}else{cross.visible=true;cross.y=shade4.y}}


stop();

我会给你几点意见（我会在我做的时候把它们编辑成这个答案，绝对没有逻辑顺序）

• 定义个人

  rnd

  s时，请在成员

  TextView[]

  中设置问题。通过这种方式，您不需要调用多少

  findViewById（）

  ，如果您了解java中的函数，这将为您节省大量代码

• shade1.addEventListener（MouseEvent.CLICK，ButtonAction2）将成为
  
  shade1.setOnClickListener(new OnClickListener() {
      public void onClick(View view) {
          buttonAction2();
      }
  };
  
  

• 您找到了

  setVisibility（）

  和

  getVisibility（）

  ，如果您只想在其他元素上禁用onClick事件，可以使用

  setEnabled（true | false）

希望这能帮助你前进。

哦，天哪！你总是这样写代码吗？换行和缩进怎么样？对不起，我做了一些修改。希望这能让它更容易阅读。很难全部复制。谢谢sam，我又开始编写代码了。我很快会在主要问题中公布我所做的事情。谢谢
