public static final int POSITION_BOTTOM_LEFT
The rounded corner is at the bottom-left of the screen.
Constant Value: 3 (0x00000003)
public static final int POSITION_BOTTOM_RIGHT
The rounded corner is at the bottom-right of the screen.
Constant Value: 2 (0x00000002)
public static final int POSITION_TOP_LEFT
The rounded corner is at the top-left of the screen.
Constant Value: 0 (0x00000000)
public static final int POSITION_TOP_RIGHT
The rounded corner is at the top-right of the screen.
Constant Value: 1 (0x00000001)
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 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 |
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:
x, x.equals(x) should return
true.
x and y, x.equals(y)
should return true if and only if
y.equals(x) returns true.
x, y, and z, if
x.equals(y) returns true and
y.equals(z) returns true, then
x.equals(z) should return true.
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.
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. |
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. |
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 |
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. |
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:
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.
equals(Object)
method, then calling the hashCode method on each of
the two objects must produce the same integer result.
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. |
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. |
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 |
