Fields

CREATOR

Added in API level 31

public static final Creator<RoundedCorner> CREATOR

Public constructors

RoundedCorner

Added in API level 31

public RoundedCorner (int position, 
                int radius, 
                int centerX, 
                int centerY)

Creates a RoundedCorner.

Note that this is only useful for tests. For production code, developers should always use a RoundedCorner obtained from the system via WindowInsets#getRoundedCorner or Display#getRoundedCorner.

Parameters
`position`	`int`: the position of the rounded corner. Value is `POSITION_TOP_LEFT`, `POSITION_TOP_RIGHT`, `POSITION_BOTTOM_RIGHT`, or `POSITION_BOTTOM_LEFT`
`radius`	`int`: the radius of the rounded corner.
`centerX`	`int`: the x of center point of the rounded corner.
`centerY`	`int`: the y of center point of the rounded corner.

Public methods

describeContents

Added in API level 31

public int describeContents ()

Describe the kinds of special objects contained in this Parcelable instance's marshaled representation. For example, if the object will include a file descriptor in the output of writeToParcel(android.os.Parcel, int), the return value of this method must include the CONTENTS_FILE_DESCRIPTOR bit.

Returns
`int`	a bitmask indicating the set of special object types marshaled by this Parcelable object instance. Value is either `0` or `CONTENTS_FILE_DESCRIPTOR`

equals

Added in API level 31

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.

An equivalence relation partitions the elements it operates on into equivalence classes; all the members of an equivalence class are equal to each other. Members of an equivalence class are substitutable for each other, at least for some purposes.

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.

getCenter

Added in API level 31

public Point getCenter ()

Returns the circle center of a quarter circle approximation of this RoundedCorner.

Returns
`Point`	the center point of this `RoundedCorner` in the application's coordinate. This value cannot be `null`.

getPosition

Added in API level 31

public int getPosition ()

Get the position of this RoundedCorner.

Returns
`int`	Value is `POSITION_TOP_LEFT`, `POSITION_TOP_RIGHT`, `POSITION_BOTTOM_RIGHT`, or `POSITION_BOTTOM_LEFT`

See also:

getRadius

Added in API level 31

public int getRadius ()

Returns the radius of a quarter circle approximation of this RoundedCorner.

Returns
`int`	the rounded corner radius of this `RoundedCorner`. Returns 0 if there is no rounded corner.

hashCode

Added in API level 31

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 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 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.

Returns
`int`	a hash code value for this object.

toString

Added in API level 31

public String toString ()

Returns a string representation of the object.

Returns
`String`	a string representation of the object.

writeToParcel

Added in API level 31

public void writeToParcel (Parcel out, 
                int flags)

Flatten this object in to a Parcel.

Parameters
`out`	`Parcel`: This value cannot be `null`.
`flags`	`int`: Additional flags about how the object should be written. May be 0 or `Parcelable.PARCELABLE_WRITE_RETURN_VALUE`. Value is either `0` or a combination of `Parcelable.PARCELABLE_WRITE_RETURN_VALUE`, and android.os.Parcelable.PARCELABLE_ELIDE_DUPLICATES
