Retuns the layout direction.

int getMarginEnd()

Returns the end margin in pixels.

int getMarginStart()

Returns the start margin in pixels.

boolean isMarginRelative()

Check if margins are relative.

void resolveLayoutDirection(int layoutDirection)

This will be called by View.requestLayout().

void setLayoutDirection(int layoutDirection)

Set the layout direction

void setMarginEnd(int end)

Sets the relative end margin.

void setMarginStart(int start)

Sets the relative start margin.

void setMargins(int left, int top, int right, int bottom)

Sets the margins, in pixels.

Object clone()

Creates and returns a copy of this object.

boolean equals(Object obj)

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

void finalize()

Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.

final Class<?> getClass()

Returns the runtime class of this Object.

int hashCode()

Returns a hash code value for the object.

final void notifyAll()

Wakes up all threads that are waiting on this object's monitor.

String toString()

Returns a string representation of the object.

final void wait(long timeoutMillis, int nanos)

Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.

final void wait(long timeoutMillis)

Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.

final void wait()

Causes the current thread to wait until it is awakened, typically by being notified or interrupted.

XML attributes

android:layout_gravity

Standard gravity constant that a child supplies to its parent. Defines how the child view should be positioned, on both the X and Y axes, within its enclosing layout.

Must be one or more (separated by '|') of the following constant values.

ConstantValueDescription
bottom50Push object to the bottom of its container, not changing its size.
center11Place the object in the center of its container in both the vertical and horizontal axis, not changing its size.
center_horizontal1Place object in the horizontal center of its container, not changing its size.
center_vertical10Place object in the vertical center of its container, not changing its size.
clip_horizontal8Additional option that can be set to have the left and/or right edges of the child clipped to its container's bounds. The clip will be based on the horizontal gravity: a left gravity will clip the right edge, a right gravity will clip the left edge, and neither will clip both edges.
clip_vertical80Additional option that can be set to have the top and/or bottom edges of the child clipped to its container's bounds. The clip will be based on the vertical gravity: a top gravity will clip the bottom edge, a bottom gravity will clip the top edge, and neither will clip both edges.
end800005Push object to the end of its container, not changing its size.
fill77Grow the horizontal and vertical size of the object if needed so it completely fills its container.
fill_horizontal7Grow the horizontal size of the object if needed so it completely fills its container.
fill_vertical70Grow the vertical size of the object if needed so it completely fills its container.
left3Push object to the left of its container, not changing its size.
right5Push object to the right of its container, not changing its size.
start800003Push object to the beginning of its container, not changing its size.
top30Push object to the top of its container, not changing its size.

Constants

UNSPECIFIED_GRAVITY

Added in API level 24
public static final int UNSPECIFIED_GRAVITY

Value for gravity indicating that a gravity has not been explicitly specified.

Constant Value: -1 (0xffffffff)

Fields

gravity

Added in API level 1
public int gravity

The gravity to apply with the View to which these layout parameters are associated.

The default value is UNSPECIFIED_GRAVITY, which is treated by FrameLayout as Gravity.TOP | Gravity.START.
