Android?Material组件库日期选择和时间选择器的使用方法

 implementation 'com.google.android.material:material:1.4.0'

private fun showTimeDialog(startDate: Date? = null) {
    val builder = MaterialTimePicker.Builder()
    //设置时间格式为24小时制
    builder.setTimeFormat(TimeFormat.CLOCK_24H)
    startDate?.let {
        builder.setHour(it.hours)
        builder.setMinute(it.minutes)
    }
    val timePicker = builder.build()
    timePicker.apply {
        // 设置事件监听器（当用户选择日期时触发）
        addOnPositiveButtonClickListener {
            val hour = timePicker.hour
            val mintue = timePicker.minute
            val hourStr = if (hour>9) hour.toString() else "0$hour"
            val mintueStr = if (mintue>9) hour.toString() else "0$mintue"
            val timeStrText = "$hourStr:$mintueStr"
            //todo 选择时间后的操作
        }
    }
    timePicker.show(supportFragmentManager, "DATE_PICKER_TAG")
}

private fun showDateDialog(startDate: Date? = null) {
    // 创建 Material 日历选择器实例
    val builder = MaterialDatePicker.Builder.datePicker()
    //设置默认选择数据
    startDate?.let {
        builder.setSelection(it.time)
    }
    // 构建 Material 日历选择器
    val materialDatePicker = builder.build()
    materialDatePicker.apply {
        // 设置事件监听器（当用户选择日期时触发）
        addOnPositiveButtonClickListener {
            val date = Date(it)
            //todo 选择时间后的操作
        }
    }
    materialDatePicker.show(supportFragmentManager, "DATE_PICKER_TAG")
}

//设置最大行数为1行(在xml中设置也可)
tvPhotoRecovery.maxLines = 1
TextViewCompat.setAutoSizeTextTypeWithDefaults(tvPhotoRecovery, TextViewCompat.AUTO_SIZE_TEXT_TYPE_UNIFORM)
//设置字体大小范围为12sp-22sp
TextViewCompat.setAutoSizeTextTypeUniformWithConfiguration(tvPhotoRecovery, 12, 22, 1, TypedValue.COMPLEX_UNIT_SP)

setAutoSizeTextTypeUniformWithConfiguration(
	TextView textView,
	int autoSizeMinTextSize, //字体最小数值
	int autoSizeMaxTextSize, //字体最大数值
	int autoSizeStepGranularity,//自动适应的步长(简单理解就是在最小和最大范围之间,从最小数值递增步长[n]来计算最符合的字体大小)
	int unit //字体单位,sp就可以
)
