| ↳ | android.view.WindowId |
Safe identifier for a window. This currently allows you to retrieve and observe
the input focus state of the window. Most applications will
not use this, instead relying on the simpler (and more efficient) methods available
on View. This classes is useful when window input interactions need to be
done across processes: the class itself is a Parcelable that can be passed to other
processes for them to interact with your window, and it provides a limited safe API
that doesn't allow the other process to negatively harm your window.

true if the specified object is equal to this Object; false otherwise.Returns an integer hash code for this object. By contract, any two
objects for which equals(Object) returns true must return
the same hash code value. This means that subclasses of Object
usually override both methods or neither method.
Note that hash values must not change over time unless information used in equals comparisons also changes.

Retrieve the current focus state of the associated window.
Start monitoring for changes in the focus state of the window.
Returns a string containing a concise, human-readable description of this object. Subclasses are encouraged to override this method and provide an implementation that takes into account the object's type and data. The default implementation is equivalent to the following expression:
getClass().getName() + '@' + Integer.toHexString(hashCode())
