public static final int ANCHOR_TYPE_MIDDLE = 1
Anchors the middle of the cue box.

Text size is measured as a fraction of the viewport size minus the view padding.
TEXT_SIZE_TYPE_FRACTIONAL_IGNORE_PADDING
public static final int TEXT_SIZE_TYPE_FRACTIONAL_IGNORE_PADDING = 1

VERTICAL_TYPE_LR
public static final int VERTICAL_TYPE_LR = 2

Public fields
bitmapHeight
public final float bitmapHeight
The bitmap height as a fraction of the of the viewport size, or DIMEN_UNSET if the bitmap should be displayed at its natural height given the bitmap dimensions and the specified size.
line
public final float line
The position of the cue box within the viewport in the direction orthogonal to the writing direction (determined by verticalType), or DIMEN_UNSET. When set, the interpretation of the value depends on the value of lineType.
The measurement direction depends on verticalType:
- For
TYPE_UNSET(i.e. horizontal), this is the vertical position relative to the top of the viewport. - For
VERTICAL_TYPE_LRthis is the horizontal position relative to the left of the viewport. - For
VERTICAL_TYPE_RLthis is the horizontal position relative to the right of the viewport.
lineAnchor
@Cue.AnchorType
public final int lineAnchor
The cue box anchor positioned by line when lineType is LINE_TYPE_FRACTION.
One of:
For the normal case of horizontal text, ANCHOR_TYPE_START, ANCHOR_TYPE_MIDDLE and ANCHOR_TYPE_END correspond to the top, middle and bottom of the cue box respectively.
lineType
@Cue.LineType
public final int lineType
The type of the line value.
LINE_TYPE_FRACTIONindicates thatlineis a fractional position within the viewport (measured to the part of the cue box determined bylineAnchor).LINE_TYPE_NUMBERindicates thatlineis a viewport line number. The viewport is divided into lines (each equal in size to the first line of the cue box). The cue box is positioned to align with the viewport lines as follows:lineAnchor) is ignored.- When
lineis greater than or equal to 0 the first line in the cue box is aligned with a viewport line, with 0 meaning the first line of the viewport. - When
lineis negative the last line in the cue box is aligned with a viewport line, with -1 meaning the last line of the viewport. - For horizontal text the start and end of the viewport are the top and bottom respectively.
multiRowAlignment
public final @Nullable Layout.Alignment multiRowAlignment
The alignment of multiple lines of text relative to the longest line, or null if the alignment is undefined.
position
public final float position
The fractional position of the positionAnchor of the cue box within the viewport in the direction orthogonal to line, or DIMEN_UNSET.
The measurement direction depends on verticalType.
- For
TYPE_UNSET(i.e. horizontal), this is the horizontal position relative to the left of the viewport. Note that positioning is relative to the left of the viewport even in the case of right-to-left text. - For
VERTICAL_TYPE_LRandVERTICAL_TYPE_RL(i.e. vertical), this is the vertical position relative to the top of the viewport.
positionAnchor
@Cue.AnchorType
public final int positionAnchor
The cue box anchor positioned by position. One of ANCHOR_TYPE_START, ANCHOR_TYPE_MIDDLE, ANCHOR_TYPE_END and TYPE_UNSET.
For the normal case of horizontal text, ANCHOR_TYPE_START, ANCHOR_TYPE_MIDDLE and ANCHOR_TYPE_END correspond to the left, middle and right of the cue box respectively.
shearDegrees
public final float shearDegrees
The shear angle in degrees to be applied to this Cue, expressed in graphics coordinates. This results in a skew transform for the block along the inline progression axis.
size
public final float size
The size of the cue box in the writing direction specified as a fraction of the viewport size in that direction, or DIMEN_UNSET.
text
public final @Nullable CharSequence text
The cue text, or null if this is an image cue. Note the CharSequence may be decorated with styling spans.
textAlignment
public final @Nullable Layout.Alignment textAlignment
The alignment of the cue text within the cue box, or null if the alignment is undefined.
textSize
public final float textSize
The default text size for this cue's text, or DIMEN_UNSET if this cue has no default text size.
textSizeType
@Cue.TextSizeType
public final int textSizeType
The default text size type for this cue's text, or TYPE_UNSET if this cue has no default text size.
verticalType
@Cue.VerticalType
public final int verticalType
The vertical formatting of this Cue, or TYPE_UNSET if the cue has no vertical setting (and so should be horizontal).
windowColorSet
public final boolean windowColorSet
Specifies whether or not the windowColor property is set.
zIndex
@UnstableApi
public final int zIndex
The Z index for cue, the larger index will render above the smaller index. May be negative.
Public methods
buildUpon
@UnstableApi
public Cue.Builder buildUpon()
Returns a new Cue.Builder initialized with the same values as this Cue.
toBinderBasedBundle
@UnstableApi
public Bundle toBinderBasedBundle()
Returns a Bundle that may contain Binder references, meaning it cannot be safely serialized to bytes.
The Bundle returned from this method can be safely sent between processes and parsed by older versions of the media3 library.
Use toSerializableBundle to get a Bundle that can be safely serialized.
toSerializableBundle
@UnstableApi
public Bundle toSerializableBundle()
Returns a Bundle that can be serialized to bytes.
Prefer the more efficient toBinderBasedBundle if the result doesn't need to be serialized.
The Bundle returned from this method must not be passed to other processes that might be using a different version of the media3 library.
