RoundedCorner
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
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
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 returntrue
. - It is symmetric: for any non-null reference values
x
andy
,x.equals(y)
should returntrue
if and only ify.equals(x)
returnstrue
. - It is transitive: for any non-null reference values
x
,y
, andz
, ifx.equals(y)
returnstrue
andy.equals(z)
returnstrue
, thenx.equals(z)
should returntrue
. - It is consistent: for any non-null reference values
x
andy
, multiple invocations ofx.equals(y)
consistently returntrue
or consistently returnfalse
, provided no information used inequals
comparisons on the objects is modified. - For any non-null reference value
x
,x.equals(null)
should returnfalse
.
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
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
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 |
getRadius
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
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 inequals
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 thehashCode
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 thehashCode
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
public String toString ()
Returns a string representation of the object.
Returns | |
---|---|
String |
a string representation of the object. |
writeToParcel
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 |
