public class DynamicLayout
extends Layout
extends Layout

DynamicLayout is a text layout that updates itself as the text is edited.

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 need to call Canvas.drawText() directly.

Constructor Summary
`DynamicLayout(CharSequence base, CharSequence display, TextPaint paint, int width, Layout.Alignment align, float spacingmult, float spacingadd, boolean includepad)` Make a layout for the transformed text (password transformation being the primary example of a transformation) that will be updated as the base text is changed.
`DynamicLayout(CharSequence base, CharSequence display, TextPaint paint, int width, Layout.Alignment align, float spacingmult, float spacingadd, boolean includepad, TextUtils.TruncateAt ellipsize, int ellipsizedWidth)` Make a layout for the transformed text (password transformation being the primary example of a transformation) that will be updated as the base text is changed.
`DynamicLayout(CharSequence base, TextPaint paint, int width, Layout.Alignment align, float spacingmult, float spacingadd, boolean includepad)` Make a layout for the specified text that will be updated as the text is changed.

Method Summary
`int`	`getBottomPadding()` Returns the number of extra pixels of descent padding in the bottom line of the Layout.
`int`	`getEllipsisCount(int line)` Returns the number of characters to be ellipsized away, or 0 if no ellipsis is to take place.
`int`	`getEllipsisStart(int line)` Return the offset of the first character to be ellipsized away, relative to the start of the line.
`int`	`getEllipsizedWidth()` Return the width to which this Layout is ellipsizing, or `Layout.getWidth()` if it is not doing anything special.
`boolean`	`getLineContainsTab(int line)` Returns whether the specified line contains one or more tabs.
`int`	`getLineCount()` Return the number of lines of text in this layout.
`int`	`getLineDescent(int line)` Return the descent of the specified line.
`Layout.Directions`	`getLineDirections(int line)` Returns an array of directionalities for the specified line.
`int`	`getLineStart(int line)` Return the text offset of the beginning of the specified line.
`int`	`getLineTop(int line)` Return the vertical position of the top of the specified line.
`int`	`getParagraphDirection(int line)` Returns the primary directionality of the paragraph containing the specified line.
`int`	`getTopPadding()` Returns the (negative) number of extra pixels of ascent padding in the top line of the Layout.

                     float spacingadd,
                     boolean includepad)

Make a layout for the specified text that will be updated as the text is changed.

                     TextUtils.TruncateAt ellipsize,
                     int ellipsizedWidth)

Make a layout for the transformed text (password transformation being the primary example of a transformation) that will be updated as the base text is changed. If ellipsize is non-null, the Layout will ellipsize the text down to ellipsizedWidth.
