class
android.text.StaticLayout
StaticLayout is a Layout for text that will not be edited after it
is laid out. Use DynamicLayout for text that may change.
This is used by widgets to control text layout. You should not need
to use this class directly unless you are implementing your own widget
or custom display object, or would be tempted to call
Canvas.drawText() directly.

StaticLayout(CharSequence source, int bufstart, int bufend, TextPaint paint, int outerwidth, Layout.Alignment align, float spacingmult, float spacingadd, boolean includepad, TextUtils.TruncateAt ellipsize, int ellipsizedWidth)
Public Methods
public
int
getBottomPadding()
Returns the number of extra pixels of descent padding in the
bottom line of the Layout.
public
int
getEllipsisCount(int line)
Returns the number of characters to be ellipsized away, or 0 if
no ellipsis is to take place.
public
int
getEllipsisStart(int line)
Return the offset of the first character to be ellipsized away,
relative to the start of the line. (So 0 if the beginning of the
line is ellipsized, not getLineStart().)
public
int
getEllipsizedWidth()
Return the width to which this Layout is ellipsizing, or
getWidth() if it is not doing anything special.
public
boolean
getLineContainsTab(int line)
Returns whether the specified line contains one or more tabs.
public
int
getLineCount()
Return the number of lines of text in this layout.
public
int
getLineDescent(int line)
Return the descent of the specified line.
public
final
Layout.Directions
getLineDirections(int line)
Returns an array of directionalities for the specified line.
The array alternates counts of characters in left-to-right
and right-to-left segments of the line.
public
int
getLineForVertical(int vertical)
Get the line number corresponding to the specified vertical position.
If you ask for a position above 0, you get 0; if you ask for a position
below the bottom of the text, you get the last line.
public
int
getLineStart(int line)
Return the text offset of the beginning of the specified line.
If the specified line is one beyond the last line, returns the
end of the last line.
public
int
getLineTop(int line)
Return the vertical position of the top of the specified line.
If the specified line is one beyond the last line, returns the
bottom of the last line.
public
int
getParagraphDirection(int line)
Returns the primary directionality of the paragraph containing
the specified line.
public
int
getTopPadding()
Returns the (negative) number of extra pixels of ascent padding in the
top line of the Layout.
