使用android将radioGroup值保存到MYSQL中

// 1. 在布局文件中添加一个RadioGroup组件
<RadioGroup
    android:id="@+id/radioGroup"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content">

    <RadioButton
        android:id="@+id/option1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Option 1" />

    <RadioButton
        android:id="@+id/option2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Option 2" />

    <RadioButton
        android:id="@+id/option3"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Option 3" />

</RadioGroup>

// 2. 在代码中获取用户选择的选项值，并发送到后端API接口
RadioGroup radioGroup = findViewById(R.id.radioGroup);
int selectedId = radioGroup.getCheckedRadioButtonId();
RadioButton selectedRadioButton = findViewById(selectedId);
String selectedOption = selectedRadioButton.getText().toString();

// 使用网络请求库发送数据到后端API接口
String url = "http://your-backend-api.com/save-option";
StringRequest request = new StringRequest(Request.Method.POST, url,
    new Response.Listener<String>() {
        @Override
        public void onResponse(String response) {
            // 处理响应结果
        }
    },
    new Response.ErrorListener() {
        @Override
        public void onErrorResponse(VolleyError error) {
            // 处理错误
        }
    }) {
    @Override
    protected Map<String, String> getParams() {
        Map<String, String> params = new HashMap<>();
        params.put("option", selectedOption);
        return params;
    }
};

RequestQueue queue = Volley.newRequestQueue(this);
queue.add(request);

// 1. 创建一个API接口，用于接收Android应用程序发送的数据
@PostMapping("/save-option")
public ResponseEntity<String> saveOption(@RequestParam("option") String option) {
    // 2. 使用MySQL的Java连接器将数据插入到数据库中
    try {
        Connection connection = DriverManager.getConnection("jdbc:mysql://your-mysql-server:3306/your-database", "username", "password");
        Statement statement = connection.createStatement();
        String query = "INSERT INTO options (option) VALUES ('" + option + "')";
        statement.executeUpdate(query);
        connection.close();
        return ResponseEntity.ok("Option saved successfully");
    } catch (SQLException e) {
        e.printStackTrace();
        return ResponseEntity.status(HttpStatus.INTERNAL_SERVER_ERROR).body("Failed to save option");
    }
}
