public class TableLayout
extends LinearLayout

A layout that arranges its children into rows and columns. A TableLayout consists of a number of TableRow objects, each defining a row (actually, you can have other children, which will be explained below). TableLayout containers do not display border lines for their rows, columns, or cells. Each row has zero or more cells; each cell can hold one View object. The table has as many columns as the row with the most cells. A table can leave cells empty. Cells can span columns, as they can in HTML.

The width of a column is defined by the row with the widest cell in that column. However, a TableLayout can specify certain columns as shrinkable or stretchable by calling setColumnShrinkable() or setColumnStretchable(). If marked as shrinkable, the column width can be shrunk to fit the table into its parent object. If marked as stretchable, it can expand in width to fit any extra space. The total width of the table is defined by its parent container. It is important to remember that a column can be both shrinkable and stretchable. In such a situation, the column will change its size to always use up the available space, but never more. Finally, you can hide a column by calling setColumnCollapsed().

The children of a TableLayout cannot specify the layout_width attribute. Width is always MATCH_PARENT. However, the layout_height attribute can be defined by a child; default value is ViewGroup.LayoutParams.WRAP_CONTENT. If the child is a TableRow, then the height is always ViewGroup.LayoutParams.WRAP_CONTENT.

Cells must be added to a row in increasing column order, both in code and XML. Column numbers are zero-based. If you don't specify a column number for a child cell, it will autoincrement to the next available column. If you skip a column number, it will be considered an empty cell in that row. See the TableLayout examples in ApiDemos for examples of creating tables in XML.

Although the typical child of a TableLayout is a TableRow, you can actually use any View subclass as a direct child of TableLayout. The View will be displayed as a single row that spans all the table columns.

Constructor Details

TableLayout

public TableLayout(Context context)

Creates a new TableLayout for the given context.

Parameters:

context - the application environment

Method Details

onViewAdded

protected void onViewAdded(View child)

Description copied from class: ViewGroup

Called when a new child is added to this ViewGroup. Overrides should always call super.onViewAdded.

Overrides:

onViewAdded in class ViewGroup

Parameters:

child - the added child view

requestLayout

public void requestLayout()

Call this when something has changed which has invalidated the layout of this view. This will schedule a layout pass of the view tree. This should not be called while the view hierarchy is currently in a layout pass (View.isInLayout(). If layout is happening, the request may be honored at the end of the current layout pass (and then layout will run again) or after the current frame is drawn and the next layout occurs.

Subclasses which override this method should call the superclass method to handle possible request-during-layout errors correctly.

Specified by:

requestLayout in interface ViewParent

Overrides:

requestLayout in class View

isShrinkAllColumns

public boolean isShrinkAllColumns()

Indicates whether all columns are shrinkable or not.

Returns:

true if all columns are shrinkable, false otherwise

setShrinkAllColumns

public void setShrinkAllColumns(boolean shrinkAllColumns)

Convenience method to mark all columns as shrinkable.

Parameters:

shrinkAllColumns - true to mark all columns shrinkable

isStretchAllColumns

public boolean isStretchAllColumns()

Indicates whether all columns are stretchable or not.

Returns:

true if all columns are stretchable, false otherwise

setStretchAllColumns

public void setStretchAllColumns(boolean stretchAllColumns)

Convenience method to mark all columns as stretchable.

Parameters:

stretchAllColumns - true to mark all columns stretchable

setColumnCollapsed

public void setColumnCollapsed(int columnIndex,
 boolean isCollapsed)

Collapses or restores a given column. When collapsed, a column does not appear on screen and the extra space is reclaimed by the other columns. A column is collapsed/restored only when it belongs to a TableRow.

Calling this method requests a layout operation.

Parameters:

columnIndex - the index of the column

isCollapsed - true if the column must be collapsed, false otherwise

isColumnCollapsed

public boolean isColumnCollapsed(int columnIndex)

Returns the collapsed state of the specified column.

Parameters:

columnIndex - the index of the column

Returns:

true if the column is collapsed, false otherwise

setColumnStretchable

public void setColumnStretchable(int columnIndex,
 boolean isStretchable)

Makes the given column stretchable or not. When stretchable, a column takes up as much as available space as possible in its row.

Calling this method requests a layout operation.

Parameters:

columnIndex - the index of the column

isStretchable - true if the column must be stretchable, false otherwise. Default is false.

isColumnStretchable

public boolean isColumnStretchable(int columnIndex)

Returns whether the specified column is stretchable or not.

Parameters:

columnIndex - the index of the column

Returns:

true if the column is stretchable, false otherwise

setColumnShrinkable

public void setColumnShrinkable(int columnIndex,
 boolean isShrinkable)

Makes the given column shrinkable or not. When a row is too wide, the table can reclaim extra space from shrinkable columns.

Calling this method requests a layout operation.

Parameters:

columnIndex - the index of the column

isShrinkable - true if the column must be shrinkable, false otherwise. Default is false.

isColumnShrinkable

public boolean isColumnShrinkable(int columnIndex)

Returns whether the specified column is shrinkable or not.

Parameters:

columnIndex - the index of the column

Returns:

true if the column is shrinkable, false otherwise. Default is false.

addView

public void addView(@NonNull
 View child)

Adds a child view. If no layout parameters are already set on the child, the default parameters for this ViewGroup are set on the child.

Note: do not invoke this method from View.draw(Canvas), View.onDraw(Canvas), ViewGroup.dispatchDraw(Canvas) or any related method.

Overrides:

addView in class ViewGroup

Parameters:

child - the child view to add

See Also:

• ViewGroup.generateDefaultLayoutParams()

addView

public void addView(@NonNull
 View child,
 int index)

Adds a child view. If no layout parameters are already set on the child, the default parameters for this ViewGroup are set on the child.

Note: do not invoke this method from View.draw(Canvas), View.onDraw(Canvas), ViewGroup.dispatchDraw(Canvas) or any related method.

Overrides:

addView in class ViewGroup

Parameters:

child - the child view to add

index - the position at which to add the child

See Also:

• ViewGroup.generateDefaultLayoutParams()

addView

public void addView(@NonNull
 View child,
 @NonNull
 ViewGroup.LayoutParams params)

Adds a child view with the specified layout parameters.

Note: do not invoke this method from View.draw(Canvas), View.onDraw(Canvas), ViewGroup.dispatchDraw(Canvas) or any related method.

Specified by:

addView in interface ViewManager

Overrides:

addView in class ViewGroup

Parameters:

child - the child view to add

params - the layout parameters to set on the child

addView

public void addView(@NonNull
 View child,
 int index,
 @NonNull
 ViewGroup.LayoutParams params)

Adds a child view with the specified layout parameters.

Note: do not invoke this method from View.draw(Canvas), View.onDraw(Canvas), ViewGroup.dispatchDraw(Canvas) or any related method.

Overrides:

addView in class ViewGroup

Parameters:

child - the child view to add

index - the position at which to add the child or -1 to add last

params - the layout parameters to set on the child

onMeasure

protected void onMeasure(int widthMeasureSpec,
 int heightMeasureSpec)

Measure the view and its content to determine the measured width and the measured height. This method is invoked by View.measure(int, int) and should be overridden by subclasses to provide accurate and efficient measurement of their contents.

CONTRACT: When overriding this method, you must call View.setMeasuredDimension(int, int) to store the measured width and height of this view. Failure to do so will trigger an IllegalStateException, thrown by View.measure(int, int). Calling super.onMeasure() is a valid use.

The base class implementation of measure defaults to the background size, unless a larger size is allowed by the MeasureSpec. Subclasses should override the base one to provide better measurements of their content.

Overrides:

onMeasure in class LinearLayout

Parameters:

widthMeasureSpec - width measure specification imposed by the parent MeasureSpec

heightMeasureSpec - height measure specification imposed by the parent MeasureSpec

onLayout

protected void onLayout(boolean changed,
 int l,
 int t,
 int r,
 int b)

Called from View.layout(int, int, int, int) when this view should assign a size and position to each of its children.

Derived classes with children should override this method and call layout on each of their children.

Overrides:

onLayout in class LinearLayout

Parameters:

changed - This is a new size or position for this view

l - Left position, relative to parent

t - Top position, relative to parent

r - Right position, relative to parent

b - Bottom position, relative to parent

generateDefaultLayoutParams

@NonNull
protected TableLayout.LayoutParams generateDefaultLayoutParams()

Returns a set of layout parameters with a width of ViewGroup.LayoutParams.MATCH_PARENT, and a height of ViewGroup.LayoutParams.WRAP_CONTENT.

Overrides:

generateDefaultLayoutParams in class LinearLayout

Returns:

a set of default layout parameters

checkLayoutParams

protected boolean checkLayoutParams(ViewGroup.LayoutParams p)

Check whether given params fit to this view group.

See also ViewGroup.generateLayoutParams(LayoutParams) See also ViewGroup.generateDefaultLayoutParams()

Overrides:

checkLayoutParams in class LinearLayout

Parameters:

p - layout params to check

Returns:

if params matched to this view group

generateLayoutParams

@NonNull
protected LinearLayout.LayoutParams generateLayoutParams(@NonNull
 ViewGroup.LayoutParams p)

Returns a safe set of layout parameters based on the supplied layout params. When a ViewGroup is passed a View whose layout params do not pass the test of ViewGroup.checkLayoutParams(LayoutParams), this method is invoked. This method should return a new set of layout params suitable for this ViewGroup, possibly by copying the appropriate attributes from the specified set of layout params.

Overrides:

generateLayoutParams in class LinearLayout

Parameters:

p - The layout parameters to convert into a suitable set of layout parameters for this ViewGroup.

Returns:

an instance of ViewGroup.LayoutParams or one of its descendants
