View.MeasureSpec

public static class View.MeasureSpec
extends Object

java.lang.Object
↳	android.view.View.MeasureSpec

A MeasureSpec encapsulates the layout requirements passed from parent to child. Each MeasureSpec represents a requirement for either the width or the height. A MeasureSpec is comprised of a size and a mode. There are three possible modes:

UNSPECIFIED: The parent has not imposed any constraint on the child. It can be whatever size it wants.
EXACTLY: The parent has determined an exact size for the child. The child is going to be given those bounds regardless of how big it wants to be.
AT_MOST: The child can be as large as it wants up to the specified size.

MeasureSpecs are implemented as ints to reduce object allocation. This class is provided to pack and unpack the <size, mode> tuple into the int.

Summary

Constants
`int`	`AT_MOST` Measure specification mode: The child can be as large as it wants up to the specified size.
`int`	`EXACTLY` Measure specification mode: The parent has determined an exact size for the child.
`int`	`UNSPECIFIED` Measure specification mode: The parent has not imposed any constraint on the child.

Public constructors
`View.MeasureSpec()`

Public methods
`static int`	`getMode(int measureSpec)` Extracts the mode from the supplied measure specification.
`static int`	`getSize(int measureSpec)` Extracts the size from the supplied measure specification.
`static int`	`makeMeasureSpec(int size, int mode)` Creates a measure specification based on the supplied size and mode.
`static String`	`toString(int measureSpec)` Returns a String representation of the specified measure specification.

Inherited methods

From class


  
    java.lang.Object

`Object`	`clone()` Creates and returns a copy of this object.
`boolean`	`equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void`	`finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>`	`getClass()` Returns the runtime class of this `Object`.
`int`	`hashCode()` Returns a hash code value for the object.
`final void`	`notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void`	`notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String`	`toString()` Returns a string representation of the object.
`final void`	`wait(long millis, int nanos)` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed.
`final void`	`wait(long millis)` Causes the current thread to wait until either another thread invokes the `notify()` method or the `notifyAll()` method for this object, or a specified amount of time has elapsed.
`final void`	`wait()` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object.
