Class StaticLayout

java.lang.Object
icyllis.modernui.text.Layout
icyllis.modernui.text.StaticLayout

public class StaticLayout extends Layout
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.

    • builder

      @NonNull public static StaticLayout.Builder builder(@NonNull CharSequence source, @IntRange(from=0L) int start, @IntRange(from=0L) int end, @NonNull TextPaint paint, @IntRange(from=0L) int width)
      Obtain a builder for constructing StaticLayout objects.
      Parameters:
      source - The text to be laid out, optionally with spans
      start - The start index (inclusive) of the text
      end - The end index (exclusive) of the text
      paint - The base (default) paint used for layout
      width - The width in pixels for each line
      Returns:
      a builder object used for constructing the StaticLayout
    • getLineForVertical

      public int getLineForVertical(int vertical)
      Description copied from class: Layout
      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.
      Overrides:
      getLineForVertical in class Layout
    • getLineCount

      public int getLineCount()
      Description copied from class: Layout
      Return the number of lines of text in this layout.
      Specified by:
      getLineCount in class Layout
    • getLineTop

      public int getLineTop(int line)
      Description copied from class: Layout
      Return the vertical position of the top of the specified line (0…getLineCount()). If the specified line is equal to the line count, returns the bottom of the last line.
      Specified by:
      getLineTop in class Layout
    • getLineDescent

      public int getLineDescent(int line)
      Description copied from class: Layout
      Return the descent of the specified line(0…getLineCount() - 1).
      Specified by:
      getLineDescent in class Layout
    • getLineStart

      public int getLineStart(int line)
      Description copied from class: Layout
      Return the text offset of the beginning of the specified line ( 0…getLineCount()). If the specified line is equal to the line count, returns the length of the text.
      Specified by:
      getLineStart in class Layout
    • getParagraphDirection

      public int getParagraphDirection(int line)
      Description copied from class: Layout
      Returns the primary directionality of the paragraph containing the specified line, either 1 for left-to-right lines, or -1 for right-to-left lines (see Layout.DIR_LEFT_TO_RIGHT, Layout.DIR_RIGHT_TO_LEFT).
      Specified by:
      getParagraphDirection in class Layout
    • getLineContainsTab

      public boolean getLineContainsTab(int line)
      Description copied from class: Layout
      Returns whether the specified line contains one or more characters that need to be handled specially, like tabs.
      Specified by:
      getLineContainsTab in class Layout
    • getLineDirections

      public final Directions getLineDirections(int line)
      Description copied from class: Layout
      Returns the directional run information for the specified line. The array alternates counts of characters in left-to-right and right-to-left segments of the line.

      NOTE: this is inadequate to support bidirectional text, and will change.

      Specified by:
      getLineDirections in class Layout
    • getTopPadding

      public int getTopPadding()
      Description copied from class: Layout
      Returns the (negative) number of extra pixels of ascent padding in the top line of the Layout.
      Specified by:
      getTopPadding in class Layout
    • getBottomPadding

      public int getBottomPadding()
      Description copied from class: Layout
      Returns the number of extra pixels of descent padding in the bottom line of the Layout.
      Specified by:
      getBottomPadding in class Layout
    • getIndentAdjust

      public int getIndentAdjust(int line, Layout.Alignment align)
      Description copied from class: Layout
      Returns the left indent for a line.
      Overrides:
      getIndentAdjust in class Layout
    • getEllipsisCount

      public int getEllipsisCount(int line)
      Description copied from class: Layout
      Returns the number of characters to be ellipsized away, or 0 if no ellipsis is to take place.
      Specified by:
      getEllipsisCount in class Layout
    • getEllipsisStart

      public int getEllipsisStart(int line)
      Description copied from class: Layout
      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().)
      Specified by:
      getEllipsisStart in class Layout
    • getEllipsizedWidth

      public int getEllipsizedWidth()
      Description copied from class: Layout
      Return the width to which this Layout is ellipsizing, or Layout.getWidth() if it is not doing anything special.
      Overrides:
      getEllipsizedWidth in class Layout
    • getHeight

      public int getHeight(boolean cap)
      Return the total height of this layout.
      Overrides:
      getHeight in class Layout
      Parameters:
      cap - if true and max lines is set, returns the height of the layout at the max lines.
