WindowInsets

public final class WindowInsets
extends Object

java.lang.Object
   ↳ android.view.WindowInsets


Describes a set of insets for window content.

WindowInsets are immutable and may be expanded to include more inset types in the future. To adjust insets, use one of the supplied clone methods to obtain a new WindowInsets instance with the adjusted properties.

Note: Before P, WindowInsets instances were only immutable during a single layout pass (i.e. would return the same values between View.onApplyWindowInsets(WindowInsets) and View.onLayout(boolean, int, int, int, int), but could return other values otherwise). Starting with P, WindowInsets are always immutable and implement equality.

equals

added in API level 20
public boolean equals (Object o)

Indicates whether some other object is "equal to" this one.

The equals method implements an equivalence relation on non-null object references:

  • It is reflexive: for any non-null reference value x, x.equals(x) should return true.
  • It is symmetric: for any non-null reference values x and y, x.equals(y) should return true if and only if y.equals(x) returns true.
  • It is transitive: for any non-null reference values x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.
  • It is consistent: for any non-null reference values x and y, multiple invocations of x.equals(y) consistently return true or consistently return false, provided no information used in equals comparisons on the objects is modified.
  • For any non-null reference value x, x.equals(null) should return false.

The equals method for class Object implements the most discriminating possible equivalence relation on objects; that is, for any non-null reference values x and y, this method returns true if and only if x and y refer to the same object (x == y has the value true).

Note that it is generally necessary to override the hashCode method whenever this method is overridden, so as to maintain the general contract for the hashCode method, which states that equal objects must have equal hash codes.

Parameters
o Object: the reference object with which to compare.

Returns
boolean true if this object is the same as the obj argument; false otherwise.

getStableInsetBottom

added in API level 21
public int getStableInsetBottom ()

Returns the bottom stable inset in pixels.

The stable inset represents the area of a full-screen window that may be partially or fully obscured by the system UI elements. This value does not change based on the visibility state of those elements; for example, if the status bar is normally shown, but temporarily hidden, the stable inset will still provide the inset associated with the status bar being shown.

Returns
int The bottom stable inset

getStableInsetLeft

added in API level 21
public int getStableInsetLeft ()

Returns the left stable inset in pixels.

The stable inset represents the area of a full-screen window that may be partially or fully obscured by the system UI elements. This value does not change based on the visibility state of those elements; for example, if the status bar is normally shown, but temporarily hidden, the stable inset will still provide the inset associated with the status bar being shown.

Returns
int The left stable inset

getStableInsetRight

added in API level 21
public int getStableInsetRight ()

Returns the right stable inset in pixels.

The stable inset represents the area of a full-screen window that may be partially or fully obscured by the system UI elements.

added in API level 20
public boolean hasInsets ()

Returns true if this WindowInsets has any nonzero insets.

Returns
boolean true if any inset values are nonzero

hasStableInsets

added in API level 21
public boolean hasStableInsets ()

Returns true if this WindowInsets has nonzero stable insets.

The stable inset represents the area of a full-screen window that may be partially or fully obscured by the system UI elements. This value does not change based on the visibility state of those elements; for example, if the status bar is normally shown, but temporarily hidden, the stable inset will still provide the inset associated with the status bar being shown.

Returns
boolean true if any of the stable inset values are nonzero

hasSystemWindowInsets

added in API level 20
public boolean hasSystemWindowInsets ()

Returns
boolean true if any of the system window inset values are nonzero

hashCode

added in API level 20
public int hashCode ()

Returns a hash code value for the object. This method is supported for the benefit of hash tables such as those provided by HashMap.

The general contract of hashCode is:

  • Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equals comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
  • If two objects are equal according to the equals(Object) method, then calling the hashCode method on each of the two objects must produce the same integer result.
  • It is not required that if two objects are unequal according to the equals(java.lang.Object) method, then calling the hashCode method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.

As much as is reasonably practical, the hashCode method defined by class Object does return distinct integers for distinct objects. (This is typically implemented by converting the internal address of the object into an integer, but this implementation technique is not required by the Java™ programming language.)

Returns
int a hash code value for this object.

isConsumed

added in API level 21
public boolean isConsumed ()

Check if these insets have been fully consumed.

Insets are considered "consumed" if the applicable consume* methods have been called such that all insets have been set to zero. This affects propagation of insets through the view hierarchy; insets that have not been fully consumed will continue to propagate down to child views.

The result of this method is equivalent to the return value of View.fitSystemWindows(android.graphics.Rect).

Returns
boolean true if the insets have been fully consumed.

isRound

added in API level 20
public boolean isRound ()

Returns true if the associated window has a round shape.

A round window's left, top, right and bottom edges reach all the way to the associated edges of the window but the corners may not be visible. Views responding to round insets should take care to not lay out critical elements within the corners where they may not be accessible.

Returns
boolean True if the window is round

replaceSystemWindowInsets

added in API level 20
public WindowInsets replaceSystemWindowInsets (int left, 
                int top, 
                int right, 
                int bottom)

Returns a copy of this WindowInsets with selected system window insets replaced with new values.

Parameters
left int: New left inset in pixels

top int: New top inset in pixels

right int: New right inset in pixels

bottom int: New bottom inset in pixels

Returns
WindowInsets A modified copy of this WindowInsets

replaceSystemWindowInsets

added in API level 21
public WindowInsets replaceSystemWindowInsets (Rect systemWindowInsets)

Returns a copy of this WindowInsets with selected system window insets replaced with new values.

Parameters
systemWindowInsets Rect: New system window insets. Each field is the inset in pixels for that edge

Returns
WindowInsets A modified copy of this WindowInsets

toString

added in API level 20
public String toString ()

Returns a string representation of the object. In general, the toString method returns a string that "textually represents" this object. The result should be a concise but informative representation that is easy for a person to read. It is recommended that all subclasses override this method.

The toString method for class Object returns a string consisting of the name of the class of which the object is an instance, the at-sign character `@', and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of:

 getClass().getName() + '@' + Integer.toHexString(hashCode())
 

Returns
String a string representation of the object.
