java - 从按钮中选择多个正确答案

Question

我的应用程序的游戏屏幕。

大家好，我目前正在开发我的问答应用游戏，其主要机制是每个问题都可能有一个或多个可能的正确答案。到目前为止，我只能从给出的选项中选择一个正确答案。

private Answer getAnswerFromCursor (Cursor cursor){
    Answer answer = new Answer();
    answer.setAnswerId(cursor.getInt(FIELD_ID_ID));
    answer.setQuestionId(cursor.getInt(FIELD_ID_QUESTIONID));
    answer.setText(cursor.getString(FIELD_ID_TEXT));

    boolean correct = (cursor.getInt(FIELD_ID_CORRECT)==1);
    answer.setCorrect(correct);

    return answer;
}

boolean 正确值用于设置数据库中的正确答案，其值为 true 设置为 1。

数据库中的正确答案，设为1。

private void displayQuestion(Question question) {

    if (question != null) {
        answers = answerData.getAnswersbyQuestionId(question.getQuestionId());
        List<Integer> myAnswersIndexList = new ArrayList<Integer>();
        for (int answerId : answers.keySet()) {
            myAnswersIndexList.add(answerId);
        }
        Collections.shuffle(myAnswersIndexList);
        answersFrame.removeAllViews();
        questionText.setText(question.getText());

        if(answers!=null){
            answersButtonsList = new ArrayList<Button>();
            Answer answer = null;


            for(int answerId : myAnswersIndexList) {

                Log.i("Captchabuster", "Adding question with Id " + answerId);
                answer = answers.get(answerId);
                Button answerButton = new Button(this);
                answerButton.setId(answer.getAnswerId());
                answerButton.setText(answer.getText());

                //handle the button-clicker
                answerButton.setOnClickListener(new View.OnClickListener()
                {
                    public void onClick(View v)
                    {
                        //timer.cancel();
                        disableAnswerButtons();
                        answerButtonClickHandler(v);

                    }

                });

                answersButtonsList.add(answerButton);
                answersFrame.addView(answerButton, answerButtonLayout);

            }
        }
    }
}

如果选择了选项中的答案并调用answerButtonClickHandler，则 onClick 方法将禁用剩余待回答的答案。

else if(questionId == 8){

    importAnswersData(db, questionId, recordData[4], false);
    importAnswersData(db, questionId, recordData[6], true);
    importAnswersData(db, questionId, recordData[5], false);
    importAnswersData(db, questionId, recordData[7], true);
    importAnswersData(db, questionId, recordData[8], true);
    importAnswersData(db, questionId, recordData[9], true);

}  

上面的代码 fragment 展示了如何将答案导入数据库。

public void answerButtonClickHandler(View v)
{
    Answer answer = answers.get(v.getId());
    if (answer != null) {
        questionAnswered++;
        if (answer.isCorrect()) {
            correctlyAnswered++;

        }
        /*    add template here
            v.setBackgroundResource(R.drawable.answer_button_correct);
         else{
            v.setBackgroundResource(R.drawable.answer_button_wrong);
        }*/
        questionDescriptionText.setText(question.getDescription());
        questionDescriptionText.setVisibility(View.VISIBLE);

        if (nextQuestionIndex < questionsIndexList.size()) {
            nextBtn.setVisibility(View.VISIBLE);
        } else{
            completeBtn.setVisibility(View.VISIBLE);
        }

    }
}

我想不出如何将用户选择的答案与我插入数据库的答案进行比较。

Answer 1

我认为您可以使用 CHeckBoxes 而不是使用按钮，并在某个数组中获取二进制值并将其与数据库值进行比较，我认为从 UI 角度来看这可能更容易、更干净。
