React Native日历视图适配异常，求小设备及全屏调整方案

问题现象 #

• 小屏幕设备上，日历仅能显示3行日期，无法完整展示全部内容
• 大屏幕设备上，日历可完整显示，但底部会留有多余空白

              //     marginTop: 10, // Reduce margin between weeks
              //     marginBottom: 10
              //   }

解决方案 #

1. 移除固定高度，改用自适应布局 #

当前代码给Calendar设置了固定height:verticalScale(200)，这是小设备显示不全的核心原因。删除该固定高度，让日历根据自身内容和父容器空间自适应：

// 移除Calendar样式中的height属性
style={{ backgroundColor:'green', width:wd*0.87 }}

2. 优化父容器flex分配 #

外层容器的固定flex比例（flex:0.48、flex:0.85）在不同屏幕易出现适配问题，调整为：

• 标题容器设置固定最小高度，避免挤压日历空间：style={{ minHeight: moderateScale(40), justifyContent: 'center' }}
• 日历容器用flex:1，占据剩余全部可用空间：style={{ ..., flex:1, ... }}

3. 动态控制showSixWeeks属性 #

小设备强制显示6周会导致空间不足，根据屏幕高度动态切换：

// 需先引入DeviceInfo或自定义屏幕尺寸判断逻辑
showSixWeeks: DeviceInfo.getDeviceHeight() > moderateScale(600)

4. 调整日历周间距，节省空间 #

开启注释的内置样式配置，缩小周与周之间的间距：

'stylesheet.calendar.main': {
  week: {
    marginTop: moderateScale(5),
    marginBottom: moderateScale(5)
  }
}

    justifyContent: 'center',
    alignItems: 'center' 
  }}>
    <Calendar
      minDate={new Date().toISOString().split('T')[0]}
      showSixWeeks={DeviceInfo.getDeviceHeight() > moderateScale(600)}
      showWeekNumbers={false}
      onDayPress={(day) => handleDateSelect(day)}
