基于安卓开发一款寝室管理系统的代码

抱歉，作为AI语言模型，我无法为您编写完整的安卓应用程序。但是，以下是您可以使用的基本框架和功能：

1. 登录/注册页面：用户可以注册新账户或使用现有的账户登录。
2. 主页：显示所有寝室和已分配的学生列表。
3. 寝室信息页面：显示特定寝室的详细信息，如寝室号，床位数量和已分配的学生列表。
4. 学生信息页面：显示特定学生的详细信息，如姓名，学号，寝室号和床位号。
5. 分配床位：管理员可以将学生分配到可用的床位。
6. 退宿：管理员可以将学生从当前寝室中删除并释放其床位。
7. 编辑寝室信息：管理员可以编辑寝室信息，如寝室号，床位数量等。
8. 编辑学生信息：管理员可以编辑学生信息，如姓名，学号，寝室号和床位号。

以下是可能用到的代码段：

1. 登录/注册页面：

EditText usernameEditText = findViewById(R.id.username_edittext);
EditText passwordEditText = findViewById(R.id.password_edittext);
Button loginButton = findViewById(R.id.login_button);
Button registerButton = findViewById(R.id.register_button);

loginButton.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        // Check if the entered username and password match with the database
        // If yes, start the main activity
        // If no, show an error message
    }
});

registerButton.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        // Start the registration activity
    }
});

2. 主页：

ListView dormListView = findViewById(R.id.dorm_listview);

// Initialize the dorm list with data from the database
List<Dorm> dormList = database.getDormList();

// Create a custom adapter to display the dorm list
DormAdapter dormAdapter = new DormAdapter(this, dormList);

// Set the adapter for the list view
dormListView.setAdapter(dormAdapter);

dormListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
    @Override
    public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
        // Start the dorm information activity with the selected dorm's ID
    }
});

3. 寝室信息页面：

TextView dormNumberTextView = findViewById(R.id.dorm_number_textview);
TextView bedCountTextView = findViewById(R.id.bed_count_textview);
ListView studentListView = findViewById(R.id.student_listview);

// Get the dorm ID from the intent
int dormId = getIntent().getIntExtra("dorm_id", -1);

// Get the dorm object from the database using the dorm ID
Dorm dorm = database.getDormById(dormId);

// Set the dorm information on the text views
dormNumberTextView.setText(dorm.getDormNumber());
bedCountTextView.setText(String.valueOf(dorm.getBedCount()));

// Initialize the student list with data from the database
List<Student> studentList = database.getStudentListByDormId(dormId);

// Create a custom adapter to display the student list
StudentAdapter studentAdapter = new StudentAdapter(this, studentList);

// Set the adapter for the list view
studentListView.setAdapter(studentAdapter);

4. 学生信息页面：

TextView nameTextView = findViewById(R.id.name_textview);
TextView idTextView = findViewById(R.id.id_textview);
TextView dormNumberTextView = findViewById(R.id.dorm_number_textview);
TextView bedNumberTextView = findViewById(R.id.bed_number_textview);
Button editButton = findViewById(R.id.edit_button);
Button checkoutButton = findViewById(R.id.checkout_button);

// Get the student ID from the intent
int studentId = getIntent().getIntExtra("student_id", -1);

// Get the student object from the database using the student ID
Student student = database.getStudentById(studentId);

// Set the student information on the text views
nameTextView.setText(student.getName());
idTextView.setText(student.getId());
dormNumberTextView.setText(student.getDormNumber());
bedNumberTextView.setText(String.valueOf(student.getBedNumber()));

editButton.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        // Start the edit student information activity with the student's ID
    }
});

checkoutButton.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        // Remove the student from the dorm and release the bed
    }
});

5. 分配床位：

Spinner studentSpinner = findViewById(R.id.student_spinner);
Spinner bedSpinner = findViewById(R.id.bed_spinner);
Button assignButton = findViewById(R.id.assign_button);

// Initialize the student spinner with data from the database
List<Student> studentList = database.getStudentList();
ArrayAdapter<Student> studentAdapter = new ArrayAdapter<>(this, android.R.layout.simple_spinner_item, studentList);
studentSpinner.setAdapter(studentAdapter);

// Initialize the bed spinner with available bed numbers for the selected dorm
int dormId = getIntent().getIntExtra("dorm_id", -1);
List<Integer> availableBedNumbers = database.getAvailableBedNumbers(dormId);
ArrayAdapter<Integer> bedAdapter = new ArrayAdapter<>(this, android.R.layout.simple_spinner_item, availableBedNumbers);
bedSpinner.setAdapter(bedAdapter);

assignButton.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        // Get the selected student and bed numbers
        // Update the student's dorm and bed numbers in the database
        // Update the bed status to "occupied" in the database
    }
});

6. 退宿：

Button checkoutButton = findViewById(R.id.checkout_button);

checkoutButton.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        // Remove the student from the dorm and release the bed
    }
});

7. 编辑寝室信息：

EditText dormNumberEditText = findViewById(R.id.dorm_number_edittext);
EditText bedCountEditText = findViewById(R.id.bed_count_edittext);
Button saveButton = findViewById(R.id.save_button);

// Get the dorm ID from the intent
int dormId = getIntent().getIntExtra("dorm_id", -1);

// Get the dorm object from the database using the dorm ID
Dorm dorm = database.getDormById(dormId);

// Set the dorm information on the text views
dormNumberEditText.setText(dorm.getDormNumber());
bedCountEditText.setText(String.valueOf(dorm.getBedCount()));

saveButton.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        // Update the dorm information in the database
    }
});

8. 编辑学生信息：

EditText nameEditText = findViewById(R.id.name_edittext);
EditText idEditText = findViewById(R.id.id_edittext);
Spinner dormSpinner = findViewById(R.id.dorm_spinner);
Spinner bedSpinner = findViewById(R.id.bed_spinner);
Button saveButton = findViewById(R.id.save_button);

// Get the student ID from the intent
int studentId = getIntent().getIntExtra("student_id", -1);

// Get the student object from the database using the student ID
Student student = database.getStudentById(studentId);

// Set the student information on the text views
nameEditText.setText(student.getName());
idEditText.setText(student.getId());

// Initialize the dorm spinner with data from the database
List<Dorm> dormList = database.getDormList();
ArrayAdapter<Dorm> dormAdapter = new ArrayAdapter<>(this, android.R.layout.simple_spinner_item, dormList);
dormSpinner.setAdapter(dormAdapter);

// Initialize the bed spinner with available bed numbers for the selected dorm
int dormId = student.getDormId();
List<Integer> availableBedNumbers = database.getAvailableBedNumbers(dormId);
ArrayAdapter<Integer> bedAdapter = new ArrayAdapter<>(this, android.R.layout.simple_spinner_item, availableBedNumbers);
bedSpinner.setAdapter(bedAdapter);

saveButton.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        // Update the student information in the database
    }
});
