Question

我正在做4种选择的多项选择。我已经下载了一个代码。但是如果答案是错误答案（同时），如何提示用户正确答案。这是代码的一个示例。正确答案是绿色的。错误的答案是红色的。

    optionOne.setOnClickListener(this);     //On First Option selection
    optionTwo.setOnClickListener(this);     //On Second Option selection
    optionThree.setOnClickListener(this);   //On Third Option selection
    optionFour.setOnClickListener(this);    //On Forth Option selection

public void onClick(View v) {
    if(v.getId() == optionOne.getId()){
        onOptionSelected(optionOne.getText().toString(), v);
        optionOne.setBackgroundColor(Color.RED);
    }else if(v.getId() == optionTwo.getId()){
        onOptionSelected(optionTwo.getText().toString(), v);
        optionTwo.setBackgroundColor(Color.RED);
    }else if(v.getId() == optionThree.getId()){
        onOptionSelected(optionThree.getText().toString(), v);
        optionThree.setBackgroundColor(Color.RED);
    }else if(v.getId() == optionFour.getId()){
        onOptionSelected(optionFour.getText().toString(), v);
        optionFour.setBackgroundColor(Color.RED);
    }else if(v.getId() == pause.getId()){   //True when Game is Paused 

//When an option of a question is selected
private void onOptionSelected(String option, View v){
    if(!isGamePaused && !isGameEnded) { //true when game is being played
        ATriviaQuestion tTQuestion = myListOfTriviaQuestions.get(currentQuestionNumber);
        if(option.equals(tTQuestion.GetOptions().get(tTQuestion.GetAnswer() - 1))) {
            correct += 1;
            v.setBackgroundColor(Color.GREEN);

        }
        else{
            incorrect += 1;
            totalPoints -= pointsPerWrongAnswer;
        }

我需要在此部分插入代码，以便在绿色背景中显示正确答案，如果用户答案不正确但我不知道如何。

else{
incorrect += 1;
totalPoints -= pointsPerWrongAnswer;

数据库问题在.plist

中

<question>
<key>Question</key>
<string>What is the ....</string>
<key>Options</key>
<array>
<string>option 1</string>
<string>option 2</string>
<string>option 3</string>
<string>option 4</string>
</array>
<key>Answer</key>
<integer>2</integer>
</question>

这是我的其他代码

public ATriviaQuestion(){
isThisQuestionAsked = false;
answer = -1;
answered = "";
}

public String GetQuestion()
{ return this.question; }

public void SetQuestion(String _question)
{ this.question=_question; }

public ArrayList<String> GetOptions()
{ return this.options; }

public void SetOptions(ArrayList<String> _options)
{ this.options = _options; }

public int GetAnswer()
{ return this.answer; }

public void SetAnswer(int _answer)
{ this.answer = _answer; }

Answer 1

我无法完全按照此处的内容进行操作，但您可以遍历options，直到文本等于tTQuestion.GetOptions().get(tTQuestion.GetAnswer() - 1)（这似乎是您获得正确答案的方式）然后设置View的背景颜色为绿色。
