枚举 TextLayout.LineBreakStrategy

java.lang.Object

java.lang.Enum<TextLayout.LineBreakStrategy>

ohos.agp.text.TextLayout.LineBreakStrategy

所有已实现的接口:

Serializable, Comparable<TextLayout.LineBreakStrategy>

封闭类:

TextLayout

public static enum TextLayout.LineBreakStrategy
extends Enum<TextLayout.LineBreakStrategy>

Enumerates the line breaking strategies.

The time required for text layout depends on whether word wrapping is required. By default, LineBreakStrategy#WORD_WRAP provides better performance.

枚举常量概要

枚举常量

枚举常量	说明
ADVANCED	Indicates the advanced line breaking strategy, which complies with the settings of HyphenationStrategy.
BALANCED	Indicates the balanced line breaking strategy, which complies with the settings of HyphenationStrategy.
WORD_WRAP	Indicates the default line breaking strategy, which is simple and fast.

方法概要

限定符和类型	方法	说明
static TextLayout.LineBreakStrategy	getByInt(int enumInt)	Obtains the LineBreakStrategy object based on the specified enumInt.
int	getValue()	Obtains the value of LineBreakStrategy in this TextLayout.
static TextLayout.LineBreakStrategy	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 TextLayout.LineBreakStrategy[]	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 (TextLayout.LineBreakStrategy c : TextLayout.LineBreakStrategy.values()) System.out.println(c);

枚举常量详细资料

WORD_WRAP

public static final TextLayout.LineBreakStrategy WORD_WRAP

Indicates the default line breaking strategy, which is simple and fast. According to this strategy, HyphenationStrategy applies only when a line has a single word and that word is longer than the line width. This strategy may result in too large blank spaces at the end of a line if long words exist.

ADVANCED

public static final TextLayout.LineBreakStrategy ADVANCED

Indicates the advanced line breaking strategy, which complies with the settings of HyphenationStrategy. This strategy tries to break lines in different places so that each line looks relatively full (except the last line of a paragraph).

BALANCED

public static final TextLayout.LineBreakStrategy BALANCED

Indicates the balanced line breaking strategy, which complies with the settings of HyphenationStrategy. This strategy tries to break lines in different places so that the width of each line looks similar (including the last line of a paragraph).

方法详细资料

values

public static TextLayout.LineBreakStrategy[] 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 (TextLayout.LineBreakStrategy c : TextLayout.LineBreakStrategy.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 TextLayout.LineBreakStrategy 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

getValue

public int getValue()

Obtains the value of LineBreakStrategy in this TextLayout.

返回:

Returns the value of LineBreakStrategy.

从以下版本开始:

7

getByInt

public static TextLayout.LineBreakStrategy getByInt(int enumInt)

Obtains the LineBreakStrategy object based on the specified enumInt.

参数:

enumInt - Indicates the enumeration value.

返回:

Returns the LineBreakStrategy object of the matched enumInt value.

从以下版本开始:
