已过时。

This change is effective since API version 6. Replaced by EstimateSpec

@Deprecated
public static class Component.MeasureSpec
extends Object

Defines the measure specifications of a component.

A MeasureSpec encapsulates the layout requirements a child inherits from the parent. Each MeasureSpec indicates the requirement for either the width or height as well as a mode. There are three possible modes for MeasureSpec: UNCONSTRAINT, PRECISE, and NOT_EXCEED.

NOT_EXCEED

@Deprecated
public static final int NOT_EXCEED

已过时。

In this mode, the maximum size has been specified for the child. The child cannot exceed the specified size.

PRECISE

@Deprecated
public static final int PRECISE

已过时。

In this mode, the parent has determined the exact size of the child.

常量字段值

UNCONSTRAINT

@Deprecated
public static final int UNCONSTRAINT

已过时。

In this mode, the parent has no constraint on the child, meaning that the child can be whatever size it wants.

getMeasureSpec

@Deprecated
public static int getMeasureSpec(int size,
                                 int mode)

已过时。

Creates a measure specification based on the specified size and mode.

参数:

size - Indicates the size contained in the measure specification. The value ranges from 0 to (1 shifted left by shifting MeasureSpec.MODE_SHIFT bits), including 1.

mode - Indicates the mode contained in the measure specification. The value must be UNCONSTRAINT, PRECISE, or NOT_EXCEED.

返回:

Returns the new measure specification.

getMode

@Deprecated
public static int getMode(int measureSpec)

已过时。

Obtains the showing mode of this component.

参数:

measureSpec - Indicates the measure specification.

返回:

Returns the showing mode of this component.

getSize

@Deprecated
public static int getSize(int measureSpec)

已过时。

Extracts the size from the provided measure specification.

参数:

measureSpec - Indicates the measure specification.

返回:

Returns the size of the measure specification.

getSizeAndConfig

@Deprecated
public static int getSizeAndConfig(int size,
                                   int estimatedConfig,
                                   int childEstimatedConfig)

已过时。

Utility to set a desired size and state in coordination with the constraints set by MeasureSpec

参数:

size - The size how big the component wants to be.

estimatedConfig - Constraints set by the parent.

childEstimatedConfig - Size information bit mask for the component's children.

返回:

bit mask for size
