Remarks
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: <dl> <dt>UNSPECIFIED</dt> <dd> The parent has not imposed any constraint on the child. It can be whatever size it wants. </dd>
<dt>EXACTLY</dt> <dd> 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. </dd>
<dt>AT_MOST</dt> <dd> The child can be as large as it wants up to the specified size. </dd> </dl>
MeasureSpecs are implemented as ints to reduce object allocation. This class is provided to pack and unpack the <size, mode> tuple into the int.

Constructors
| Name | Description |
|---|---|
| View.MeasureSpec() |
Initializes a new instance of View.MeasureSpec. |
| View.MeasureSpec(IntPtr, JniHandleOwnership) |
A constructor used when creating managed representations of JNI objects; called by the runtime. |
Properties
| Name | Description |
|---|---|
| Class |
Returns the runtime class of this |
| Handle |
The handle to the underlying Android instance. (Inherited from Object) |
| JniIdentityHashCode |
Gets the identity hash code assigned to this Java peer by the interop runtime. (Inherited from Object) |
| JniManagedPeerState |
Gets the state flags last assigned by the runtime. (Inherited from JavaObject) |
| JniPeerMembers |
Gets the JNI peer metadata used by the .NET for Android binding runtime. |
| PeerReference |
Gets the JNI object reference for this Java peer. (Inherited from Object) |
| ThresholdClass |
Gets the JNI class handle used by the .NET for Android binding runtime. |
| ThresholdType |
Gets the managed type used by the .NET for Android binding runtime. |
Methods
| Name | Description |
|---|---|
| Clone() |
Creates and returns a copy of this object. (Inherited from Object) |
| Construct(JniObjectReference, JniObjectReferenceOptions) |
Delegates construction of this peer to the runtime's value manager. (Inherited from JavaObject) |
| Dispose() |
Releases the resources held by this Java peer. (Inherited from Object) |
| Dispose(Boolean) |
Releases the resources held by this Java peer. (Inherited from Object) |
| DisposeUnlessReferenced() |
Asks the value manager to dispose this peer unless its mapping retains this same managed instance. (Inherited from JavaObject) |
| Equals(Object) |
Tests whether another managed peer refers to the same Java object. (Inherited from JavaObject) |
| Equals(Object) |
Indicates whether some other object is "equal to" this one. (Inherited from Object) |
| GetHashCode() |
Returns a hash code value for the object. (Inherited from Object) |
| GetMode(Int32) |
Extracts the mode from the supplied measure specification. |
| GetSize(Int32) |
Extracts the size from the supplied measure specification. |
| JavaFinalize() |
Obsolete.
Called by the garbage collector on an object when garbage collection determines that there are no more references to the object. (Inherited from Object) |
| MakeMeasureSpec(Int32, MeasureSpecMode) |
Creates a measure specification based on the supplied size and mode. |
| Notify() |
Wakes up a single thread that is waiting on this object's monitor. (Inherited from Object) |
| NotifyAll() |
Wakes up all threads that are waiting on this object's monitor. (Inherited from Object) |
| SetHandle(IntPtr, JniHandleOwnership) |
Sets the Handle property. (Inherited from Object) |
| SetPeerReference(JniObjectReference, JniObjectReferenceOptions) |
Stores a reference value in the control block without creating a JNI reference copy. (Inherited from JavaObject) |
| ToArray<T>() |
Creates a managed array from this Java array wrapper. (Inherited from Object) |
| ToString() |
Returns a string representation of the object. (Inherited from Object) |
| ToString(Int32) |
Returns a String representation of the specified measure specification. |
| UnregisterFromRuntime() |
Unregisters this Java peer from the interop runtime. (Inherited from Object) |
| Wait() |
Causes the current thread to wait until it is awakened, typically by being <em>notified</em> or <em>interrupted</em>. (Inherited from Object) |
| Wait(Int64, Int32) |
Causes the current thread to wait until it is awakened, typically by being <em>notified</em> or <em>interrupted</em>, or until a certain amount of real time has elapsed. (Inherited from Object) |
| Wait(Int64) |
Causes the current thread to wait until it is awakened, typically by being <em>notified</em> or <em>interrupted</em>, or until a certain amount of real time has elapsed. (Inherited from Object) |
