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 main axis.
FLEX_END	The components are aligned with the end edge of the main axis (main-end).
FLEX_START	The components are aligned with the start edge along the main axis (main-start).
SPACE_AROUND	The components are evenly distributed along the main axis, with a half-size space on either end.
SPACE_BETWEEN	The components are evenly distributed along the main axis.
SPACE_EVENLY	The components are evenly distributed along the main axis.

方法概要

限定符和类型	方法	说明
static JustifyContent	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 JustifyContent[]	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 (JustifyContent c : JustifyContent.values()) System.out.println(c);

枚举常量详细资料

FLEX_START

public static final JustifyContent FLEX_START

The components are aligned with the start edge along the main axis (main-start).

FLEX_END

public static final JustifyContent FLEX_END

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

CENTER

public static final JustifyContent CENTER

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

SPACE_BETWEEN

public static final JustifyContent SPACE_BETWEEN

The components are evenly distributed along the main axis. The first component is aligned with the main-start, the last component is aligned with the main-end, and the remaining components are distributed so that the space between any two adjacent components is the same.

SPACE_AROUND

public static final JustifyContent SPACE_AROUND

The components are evenly distributed along the main axis, with a half-size space on either end. The space between any two adjacent components is the same. The space between the first component and main-start, and that between the last component and main-end are both half the size of the space between two adjacent components.

SPACE_EVENLY

public static final JustifyContent SPACE_EVENLY

The components are evenly distributed along the main axis. The space between any two adjacent components, the first component and main-start, and the last component and main-end, are all the same.

方法详细资料

values

public static JustifyContent[] 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 (JustifyContent c : JustifyContent.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 JustifyContent 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
