Field Detail

DIMEN_UNSET

public static final float DIMEN_UNSET

An unset position or width.

Constant Field Values

TYPE_UNSET

public static final int TYPE_UNSET

An unset anchor or line type value.

Constant Field Values

ANCHOR_TYPE_START

public static final int ANCHOR_TYPE_START

Anchors the left (for horizontal positions) or top (for vertical positions) edge of the cue box.

Constant Field Values

ANCHOR_TYPE_MIDDLE

public static final int ANCHOR_TYPE_MIDDLE

Anchors the middle of the cue box.

Constant Field Values

ANCHOR_TYPE_END

public static final int ANCHOR_TYPE_END

Anchors the right (for horizontal positions) or bottom (for vertical positions) edge of the cue box.

See Also:

Constant Field Values

LINE_TYPE_FRACTION

public static final int LINE_TYPE_FRACTION

Value for lineType when line is a fractional position.

See Also:

Constant Field Values

LINE_TYPE_NUMBER

public static final int LINE_TYPE_NUMBER

Value for lineType when line is a line number.

See Also:

Constant Field Values

text

public final java.lang.CharSequence text

The cue text. Note the CharSequence may be decorated with styling spans.

textAlignment

public final android.text.Layout.Alignment textAlignment

The alignment of the cue text within the cue box, or null if the alignment is undefined.

line

public final float line

The position of the lineAnchor of the cue box within the viewport in the direction orthogonal to the writing direction, or DIMEN_UNSET. When set, the interpretation of the value depends on the value of lineType.

For horizontal text and lineType equal to LINE_TYPE_FRACTION, this is the fractional vertical position relative to the top of the viewport.

lineType

public final int lineType

The type of the line value.

LINE_TYPE_FRACTION indicates that line is a fractional position within the viewport.

LINE_TYPE_NUMBER indicates that line is a line number, where the size of each line is taken to be the size of the first line of the cue. When line is greater than or equal to 0, lines count from the start of the viewport (the first line is numbered 0). When line is negative, lines count from the end of the viewport (the last line is numbered -1). For horizontal text the size of the first line of the cue is its height, and the start and end of the viewport are the top and bottom respectively.

lineAnchor

public final int lineAnchor

The cue box anchor positioned by line. 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 top, middle and bottom of the cue box respectively.

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.

For horizontal text, 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.

positionAnchor

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.

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.
