ItemAlignmentFacet.ItemAlignmentDef ()

Public methods

getItemAlignmentFocusViewId

added in version 24.1.0
int getItemAlignmentFocusViewId ()

Returns Id of which child view take focus for alignment. When not set, it will use use same id of getItemAlignmentViewId()

Returns
int

getItemAlignmentOffset

added in version 24.1.0
int getItemAlignmentOffset ()

Returns number of pixels to the end of low edge. Supports right to left layout direction. In left to right or vertical case, it's the offset added to left/top edge. In right to left case, it's the offset subtracted from right edge.

Returns
int Number of pixels to the end of low edge.

getItemAlignmentOffsetPercent

added in version 24.1.0
float getItemAlignmentOffsetPercent ()

Gets the offset percent for item alignment in addition to offset. E.g., 40 means 40% of the width from the low edge. In the right to left case, it's the 40% from right edge. Use ITEM_ALIGN_OFFSET_PERCENT_DISABLED to disable.

Returns
float

getItemAlignmentViewId

added in version 24.1.0
int getItemAlignmentViewId ()

Returns Id of which child view to be aligned. View.NO_ID refers to root view and should be only used in first one. Different view ids of #getAlignmentDefs() define multiple alignment steps within one itemView, e.g. there are two child views R.id.child1 and R.id.child2. App may allocated two ItemAlignmentFacet.ItemAlignmentDefs, one with view id R.id.child1, the other with view id R.id.child2. Note this id may or may not be same as the child view that takes focus.

Returns
int

isAlignedToTextViewBaseLine

added in version 24.1.0
boolean isAlignedToTextViewBaseLine ()

Returns true when View should be aligned to getBaseline()

Returns
boolean

isItemAlignmentOffsetWithPadding

added in version 24.1.0
boolean isItemAlignmentOffsetWithPadding ()

Returns true if applies padding to item alignment when getItemAlignmentOffsetPercent() is 0 or 100; returns false otherwise.

When true: Applies start/top padding when getItemAlignmentOffsetPercent() is 0. Applies end/bottom padding when getItemAlignmentOffsetPercent() is 100. Does not apply padding if getItemAlignmentOffsetPercent() is neither 0 nor 100.

When false: does not apply padding

Returns
boolean

setAlignedToTextViewBaseline

added in version 24.1.0
void setAlignedToTextViewBaseline (boolean alignToBaseline)

When true, align to getBaseline() for the view of with id equals getItemAlignmentViewId(); false otherwise.

Parameters
alignToBaseline boolean: Boolean indicating whether to align to view baseline.

setItemAlignmentFocusViewId

added in version 24.1.0
void setItemAlignmentFocusViewId (int viewId)

Sets Id of which child view take focus for alignment. When not set, it will use use same id of getItemAlignmentViewId().

Parameters
viewId int: The id of child view that will be focused to.

setItemAlignmentOffset

added in version 24.1.0
void setItemAlignmentOffset (int offset)

Sets number of pixels to the end of low edge. Supports right to left layout direction.

Parameters
offset int: In left to right or vertical case, it's the offset added to left/top edge. In right to left case, it's the offset subtracted from right edge.

setItemAlignmentOffsetPercent

added in version 24.1.0
void setItemAlignmentOffsetPercent (float percent)

Sets the offset percent for item alignment in addition to offset. E.g., 40 means 40% of width/height from the low edge. In the right to left case, it's the 40% width from right edge. Use ITEM_ALIGN_OFFSET_PERCENT_DISABLED to disable.

Parameters
percent float

setItemAlignmentOffsetWithPadding

added in version 24.1.0
void setItemAlignmentOffsetWithPadding (boolean withPadding)

Sets whether applies padding to item alignment when getItemAlignmentOffsetPercent() is 0 or 100.

When true: Applies start/top padding if getItemAlignmentOffsetPercent() is 0. Applies end/bottom padding if getItemAlignmentOffsetPercent() is 100. Does not apply padding if getItemAlignmentOffsetPercent() is neither 0 nor 100.

When false: does not apply padding

Parameters
withPadding boolean

setItemAlignmentViewId

added in version 24.1.0
void setItemAlignmentViewId (int viewId)

Sets Id of which child view to be aligned. View.NO_ID refers to root view and should be only used in first one. Different view ids of #getAlignmentDefs() define multiple alignment steps within one itemView, e.g. there are two child views R.id.child1 and R.id.child2. App may allocated two ItemAlignmentFacet.ItemAlignmentDefs, one with view id R.id.child1, the other with view id R.id.child2. Note this id may or may not be same as the child view that takes focus.

Parameters
viewId int: The id of child view that will be aligned to.
