枚举 Component.LayoutDirection

java.lang.Object

java.lang.Enum<Component.LayoutDirection>

ohos.agp.components.Component.LayoutDirection

所有已实现的接口:

Serializable, Comparable<Component.LayoutDirection>

封闭类:

Component

public static enum Component.LayoutDirection
extends Enum<Component.LayoutDirection>

Enumerates horizontal layout directions. The layout direction can be LTR or RTL. It can also be inherited (INHERIT) from a parent component or deduced from the locale settings (LOCALE).

从以下版本开始:

枚举常量概要

枚举常量

枚举常量	说明
INHERIT	Indicates that the horizontal layout direction is inherited.
LOCALE	Indicates that the horizontal layout direction is deduced from the locale settings.
LTR	Indicates that the horizontal layout direction is from left to right.
RTL	Indicates that the horizontal layout direction is from right to left.

方法概要

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

枚举常量详细资料

LTR

public static final Component.LayoutDirection LTR

Indicates that the horizontal layout direction is from left to right.

RTL

public static final Component.LayoutDirection RTL

Indicates that the horizontal layout direction is from right to left.

INHERIT

public static final Component.LayoutDirection INHERIT

Indicates that the horizontal layout direction is inherited.

LOCALE

public static final Component.LayoutDirection LOCALE

Indicates that the horizontal layout direction is deduced from the locale settings.

方法详细资料

values

public static Component.LayoutDirection[] 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 (Component.LayoutDirection c : Component.LayoutDirection.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 Component.LayoutDirection 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
