枚举 AlignItems

java.lang.Object

java.lang.Enum<AlignItems>

ohos.agp.components.flex.AlignItems

所有已实现的接口:

Serializable, Comparable<AlignItems>

public enum AlignItems
extends Enum<AlignItems>

Enumerates the alignment modes for all components in a single-line FlexLayout along the cross axis.

枚举常量概要

枚举常量

枚举常量	说明
CENTER	The components are aligned in the center of the cross axis.
FLEX_END	The components are aligned with the end edge of the cross axis (cross-end).
FLEX_START	The components are aligned with the start edge of the cross axis (cross-start).
STRETCH	The components are stretched along the cross axis to fill the line.

方法概要

限定符和类型	方法	说明
static AlignItems	valueOf(String name)	返回带有指定名称的该类型的枚举常量。 字符串必须与用于声明该类型的枚举常量的 标识符完全匹配。(不允许有多余 的空格字符。)
static AlignItems[]	values()	按照声明该枚举类型的常量的顺序, 返回 包含这些常量的数组。该方法可用于迭代 常量, 如下所示: for (AlignItems c : AlignItems.values()) System.out.println(c);

枚举常量详细资料

FLEX_START

public static final AlignItems FLEX_START

The components are aligned with the start edge of the cross axis (cross-start).

FLEX_END

public static final AlignItems FLEX_END

The components are aligned with the end edge of the cross axis (cross-end).

CENTER

public static final AlignItems CENTER

The components are aligned in the center of the cross axis.

STRETCH

方法详细资料

values

public static AlignItems[] values()

按照声明该枚举类型的常量的顺序, 返回 包含这些常量的数组。该方法可用于迭代 常量, 如下所示:

for (AlignItems c : AlignItems.values())
    System.out.println(c);

返回:

按照声明该枚举类型的常量的顺序返回的包含这些常量的数组

valueOf

public static AlignItems valueOf(String name)

返回带有指定名称的该类型的枚举常量。 字符串必须与用于声明该类型的枚举常量的 标识符完全匹配。(不允许有多余 的空格字符。)

参数:

name - 要返回的枚举常量的名称。

返回:

返回带有指定名称的枚举常量

抛出:

IllegalArgumentException - 如果该枚举类型没有带有指定名称的常量

NullPointerException - 如果参数为空值
