我用actionscript做了一个测验。我已经开始在android(完整的新手)中进行测验,遵循动作脚本,以免让我的逻辑陷入困境。

我不知道如何处理 change_question 函数,尤其是第一块。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);

任何指导将不胜感激。提前致谢。


到目前为止,这是我的 android 代码!

package ks3.mathsapp.project;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.ImageView;
import android.widget.TextView;

public class MathsMultiplicationActivity extends Activity {


TextView quesnum;
TextView ques;
TextView anst;
TextView ans1;
TextView ans2;
TextView ans3;
TextView ans4;
ImageView cross;
ImageView tick;


    int qno = 0;
    int right_answers = 0;
    int wrong_answers = 0;
    int rnd1;
    int rnd2;

    String [] questions = {"How much mph does the F-Duct add to the car?",
              "What car part is considered the biggest performance variable?",
              "What car part is designed to speed up air flow at the car rear?",
              "In seconds, how long does it take for a F1 car to stop when travelling at 300km/h?",
              "How many litres of air does an F1 car consume per second?",
              "What car part can heavily influence oversteer and understeer?",
              "A third of the cars downforce can come from what?",
              "Around how much race fuel would be consumed per 100km?","The first high nose cone was introduced when?",
              "An increase in what, has led to the length of exhaust pipes being shortened drastically?"};

    String [] [] answers = {{"3","5","8","9"},
    {"Tyres","Front Wing","F-Duct","Engine"},
    {"Diffuser","Suspension","Tyres","Exhaust"},
    {"4","6","8","10"},
    {"650","10","75","450"},
    {"Suspension","Tyres","Cockpit","Chassis"},
    {"Rear Wing","Nose Cone","Chassis","Engine"},
    {"75 Litres","100 Litres","50 Litres","25 Litres"},
    {"1990","1989","1993","1992"},
    {"Engine RPM","Nose Cone Lengths","Tyre Size","Number of Races"}};

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.multiplechoice);


    // Importing all assets like buttons, text fields
    quesnum = (TextView) findViewById(R.id.questionNum);
    ques = (TextView) findViewById(R.id.question);
    anst = (TextView) findViewById(R.id.answertit);
    ans1 = (TextView) findViewById(R.id.answer1);
    ans2 = (TextView) findViewById(R.id.answer2);
    ans3 = (TextView) findViewById(R.id.answer3);
    ans4 = (TextView) findViewById(R.id.answer4);
    cross = (ImageView) findViewById(R.id.cross);
    tick = (ImageView) findViewById(R.id.tick);

    cross.setVisibility(View.GONE); 
    tick.setVisibility(View.GONE); 



        if(rnd1==1){
            TextView quesAns1 = (TextView) findViewById(R.id.answer1); 
            quesAns1.setText("1) " + answers[0]) ;            

            TextView quesAns2 = (TextView) findViewById(R.id.answer2); 
            quesAns2.setText("2) " + answers[1]) ;   

            TextView quesAns3 = (TextView) findViewById(R.id.answer3); 
            quesAns3.setText("3) " + answers[2]) ;   

            TextView quesAns4 = (TextView) findViewById(R.id.answer4); 
            quesAns4.setText("4) " + answers[3]) ;   
        }

        if(rnd1==2){
            TextView quesAns1 = (TextView) findViewById(R.id.answer1); 
            quesAns1.setText("1) " + answers[2]) ;            

            TextView quesAns2 = (TextView) findViewById(R.id.answer2); 
            quesAns2.setText("2) " + answers[0]) ;   

            TextView quesAns3 = (TextView) findViewById(R.id.answer3); 
            quesAns3.setText("3) " + answers[1]) ;   

            TextView quesAns4 = (TextView) findViewById(R.id.answer4); 
            quesAns4.setText("4) " + answers[3]) ;  
        }
        if(rnd1==3){
            TextView quesAns1 = (TextView) findViewById(R.id.answer1); 
            quesAns1.setText("1) " + answers[1]) ;            

            TextView quesAns2 = (TextView) findViewById(R.id.answer2); 
            quesAns2.setText("2) " + answers[2]) ;   

            TextView quesAns3 = (TextView) findViewById(R.id.answer3); 
            quesAns3.setText("3) " + answers[0]) ;   

            TextView quesAns4 = (TextView) findViewById(R.id.answer4); 
            quesAns4.setText("4) " + answers[3]) ;  
        }


    }


    }   

这是我一直用来帮助处理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(我会随时将它们编辑成这个答案,绝对没有逻辑顺序)。

  • 当您定义您的个人时rnd,请在成员中设置您的问题TextView[]。这样你就不需要多少调用findViewById(),如果了解java中增强的for循环,这将为你节省大量代码。

  • shade1.addEventListener(MouseEvent.CLICK, ButtonAction2);会变成

    shade1.setOnClickListener(new OnClickListener() {
        public void onClick(View view) {
            buttonAction2();
        }
    };
    
  • 你找到了setVisibilty()and getVisibility(),如果你只是想在其他元素上禁用 onClick 事件,你可以使用setEnabled(true | false)

希望这有助于推动你前进。
