枚举 TextLayout.FontPaddingStrategy

java.lang.Object

java.lang.Enum<TextLayout.FontPaddingStrategy>

ohos.agp.text.TextLayout.FontPaddingStrategy

所有已实现的接口:

Serializable, Comparable<TextLayout.FontPaddingStrategy>

封闭类:

TextLayout

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

Enumerates the font padding strategies.

Font padding is the space between the ascent and top, or between the descent and bottom. Font designers don't guarantee that all glyphs are constrained between ascent and decent, so using padding can guarantee that the upper and lower edges of the text are not clipped.

枚举常量概要

枚举常量

枚举常量	说明
EVERY_LINE	Indicates that padding is added to every line.
NONE	Indicates no padding.
ONLY_FIRST_AND_LAST_LINE	Indicates that padding is added only to the first line and the last line.

方法概要

限定符和类型	方法	说明
static TextLayout.FontPaddingStrategy	getByInt(int enumInt)	Obtains the enumeration object according to the value.
int	getValue()	Obtains the value of the FontPaddingStrategy type.
static TextLayout.FontPaddingStrategy	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.FontPaddingStrategy[]	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.FontPaddingStrategy c : TextLayout.FontPaddingStrategy.values()) System.out.println(c);

枚举常量详细资料

ONLY_FIRST_AND_LAST_LINE

public static final TextLayout.FontPaddingStrategy ONLY_FIRST_AND_LAST_LINE

Indicates that padding is added only to the first line and the last line. It is the default strategy. This strategy ensures that no clipping will happen and the line height is compact.

EVERY_LINE

public static final TextLayout.FontPaddingStrategy EVERY_LINE

Indicates that padding is added to every line. This strategy ensures that no clipping will happen and the lines will not overlap.

NONE

public static final TextLayout.FontPaddingStrategy NONE

Indicates no padding. In this strategy, clipping may happen, and the line height is smallest.

方法详细资料

values

public static TextLayout.FontPaddingStrategy[] 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.FontPaddingStrategy c : TextLayout.FontPaddingStrategy.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.FontPaddingStrategy 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 the FontPaddingStrategy type.

返回:

Returns the value of the FontPaddingStrategy type.

getByInt

public static TextLayout.FontPaddingStrategy getByInt(int enumInt)

Obtains the enumeration object according to the value.

参数:

enumInt - Indicates the enumeration value of the indicator.

返回:

Returns the enumerated type of the matched enumInt value.
