如何创建动态变量名？Android Studio id名称问题

import java.lang.reflect.Field;

public class MainActivity extends AppCompatActivity {
    
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        String dynamicVariableName = "dynamicVariable";
        int dynamicVariableValue = 10;

        try {
            // 获取类的引用
            Class<?> cls = R.id.class;
            // 获取字段的引用
            Field field = cls.getDeclaredField(dynamicVariableName);
            // 设置字段可访问
            field.setAccessible(true);
            // 为字段赋值
            field.set(this, dynamicVariableValue);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
