Constructors

RectF()

Create a new empty RectF.

RectF(IntPtr, JniHandleOwnership)

A constructor used when creating managed representations of JNI objects; called by the runtime.

RectF(Rect)
RectF(RectF)

Create a new rectangle, initialized with the values in the specified rectangle (which is left unmodified).

RectF(Single, Single, Single, Single)

Create a new rectangle with the specified coordinates.

Methods

CenterX()
CenterY()
Clone()

Creates and returns a copy of this Object.

(Inherited from Object)
Contains(RectF)

Returns true iff the specified rectangle r is inside or equal to this rectangle.

Contains(Single, Single)

Returns true if (x,y) is inside the rectangle.

Contains(Single, Single, Single, Single)

Returns true iff the 4 specified sides of a rectangle are inside or equal to this rectangle. i.e. is this rectangle a superset of the specified rectangle.

DescribeContents()

Parcelable interface methods

Dispose() (Inherited from Object)
Dispose(Boolean) (Inherited from Object)
Equals(Object)

Compares this instance with the specified object and indicates if they are equal.

(Inherited from Object)
GetHashCode()

Returns an integer hash code for this object.

(Inherited from Object)
Height()
Inset(Single, Single)

Inset the rectangle by (dx,dy).

Intersect(RectF)

If the specified rectangle intersects this rectangle, return true and set this rectangle to that intersection, otherwise return false and do not change this rectangle.

Intersect(Single, Single, Single, Single)

If the rectangle specified by left,top,right,bottom intersects this rectangle, return true and set this rectangle to that intersection, otherwise return false and do not change this rectangle.

Intersects(RectF, RectF)

Returns true iff the two specified rectangles intersect.

Intersects(Single, Single, Single, Single)

Returns true if this rectangle intersects the specified rectangle.

JavaFinalize()

Invoked when the garbage collector has detected that this instance is no longer reachable.

(Inherited from Object)
Notify()

Causes a thread which is waiting on this object's monitor (by means of calling one of the wait() methods) to be woken up.

(Inherited from Object)
NotifyAll()

Causes all threads which are waiting on this object's monitor (by means of calling one of the wait() methods) to be woken up.

(Inherited from Object)
Offset(Single, Single)

Offset the rectangle by adding dx to its left and right coordinates, and adding dy to its top and bottom coordinates.

OffsetTo(Single, Single)

Offset the rectangle to a specific (left, top) position, keeping its width and height the same.

ReadFromParcel(Parcel)

Set the rectangle's coordinates from the data stored in the specified parcel.

Round(Rect)

Set the dst integer Rect by rounding this rectangle's coordinates to their nearest integer values.

RoundOut(Rect)

Set the dst integer Rect by rounding "out" this rectangle, choosing the floor of top and left, and the ceiling of right and bottom.

Set(Rect)

Copy the coordinates from src into this rectangle.

Set(RectF)

Copy the coordinates from src into this rectangle.

Set(Single, Single, Single, Single)

Set the rectangle's coordinates to the specified values.

SetEmpty()

Set the rectangle to (0,0,0,0)

SetHandle(IntPtr, JniHandleOwnership)

Sets the Handle property.

(Inherited from Object)
SetIntersect(RectF, RectF)

If rectangles a and b intersect, return true and set this rectangle to that intersection, otherwise return false and do not change this rectangle.

Sort()

Swap top/bottom or left/right if there are flipped (i.e. left > right and/or top > bottom).

ToArray<T>() (Inherited from Object)
ToShortString()

Return a string representation of the rectangle in a compact form.

ToString()

Returns a string containing a concise, human-readable description of this object.

(Inherited from Object)
Union(RectF)

Update this Rect to enclose itself and the specified rectangle.

Union(Single, Single)

Update this Rect to enclose itself and the [x,y] coordinate.

Union(Single, Single, Single, Single)

Update this Rect to enclose itself and the specified rectangle.

UnregisterFromRuntime() (Inherited from Object)
Wait()

Causes the calling thread to wait until another thread calls the notify() or notifyAll() method of this object.

(Inherited from Object)
Wait(Int64)

Causes the calling thread to wait until another thread calls the notify() or notifyAll() method of this object or until the specified timeout expires.

(Inherited from Object)
Wait(Int64, Int32)

Causes the calling thread to wait until another thread calls the notify() or notifyAll() method of this object or until the specified timeout expires.

(Inherited from Object)
Width()
WriteToParcel(Parcel, ParcelableWriteFlags)

Write this rectangle to the specified parcel.
