数据结构具体代码实现
好的,我可以提供一个简单的代码示例来帮助你实现这个判断题题库 Android APP。由于篇幅限制,以下代码可能不是完整的,但应该可以让你了解如何实现该应用的基本功能。
首先,我们定义一个 Question 类来保存每个判断题的信息:
```java
public class Question {
private String content;
private boolean answer;
private boolean userAnswer;
public Question(String content, boolean answer) {
this.content = content;
this.answer = answer;
this.userAnswer = false;
}
public String getContent() {
return content;
}
public boolean getAnswer() {
return answer;
}
public boolean getUserAnswer() {
return userAnswer;
}
public void setUserAnswer(boolean userAnswer) {
this.userAnswer = userAnswer;
}
}
```
接下来,我们创建一个 MainActivity 类来实现主界面的逻辑:
```java
public class MainActivity extends AppCompatActivity {
private List<Question> questionList;
private int currentQuestionIndex;
private List<Boolean> userAnswers;
private TextView questionTextView;
private Button trueButton;
private Button falseButton;
private Button nextButton;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// 初始化题库
initQuestionList();
// 初始化界面组件
questionTextView = findViewById(R.id.questionTextView);
trueButton = findViewById(R.id.trueButton);
falseButton = findViewById(R.id.falseButton);
nextButton = findViewById(R.id.nextButton);
// 显示第一道题目
showQuestion(0);
// 设置“正确”按钮的点击事件
trueButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
answerQuestion(true);
}
});
// 设置“错误”按钮的点击事件
falseButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
answerQuestion(false);
}
});
// 设置“下一个”按钮的点击事件
nextButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
showNextQuestion();
}
});
}
// 初始化题库
private void initQuestionList() {
questionList = new ArrayList<>();
questionList.add(new Question("1 + 1 = 2", true));
questionList.add(new Question("2 + 2 = 5", false));
questionList.add(new Question("3 + 3 = 7", false));
questionList.add(new Question("4 + 4 = 8", true));
userAnswers = new ArrayList<>();
}
// 显示指定索引的题目
private void showQuestion(int index) {
Question question = questionList.get(index);
questionTextView.setText(question.getContent());
}
// 回答当前题目
private void answerQuestion(boolean answer) {
Question question = questionList.get(currentQuestionIndex);
question.setUserAnswer(answer);
}
// 显示下一个题目
private void showNextQuestion() {
if (currentQuestionIndex < questionList.size() - 1) {
currentQuestionIndex++;
showQuestion(currentQuestionIndex);
} else {
// 进入结果页面
Intent intent = new Intent(this, ResultActivity.class);
intent.putExtra("userAnswers", (Serializable) userAnswers);
startActivity(intent);
}
}
}
```
最后,我们创建一个 ResultActivity 类来实现结果页面的逻辑:
```java
public class ResultActivity extends AppCompatActivity {
private List<Boolean> userAnswers;
private TextView scoreTextView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_result);
// 获取用户答案列表
userAnswers = (List<Boolean>) getIntent().getSerializableExtra("userAnswers");
// 初始化界面组件
scoreTextView = findViewById(R.id.scoreTextView);
// 计算得分并显示
int score = calculateScore();
scoreTextView.setText("您的得分为:" + score);
}
// 计算得分
private int calculateScore() {
int score = 0;
for (int i = 0; i < userAnswers.size(); i++) {
if (userAnswers.get(i) == questionList.get(i).getAnswer()) {
score++;
}
}
return score;
}
}
```
以上就是一个简单的判断题题库 Android APP 的实现代码,希望可以帮助到你。
