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 FILL_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.

ViewGroup.generateDefaultLayoutParams()

addView

public void addView(View child,
                    int index)

Parameters:

child - the child view to add

index - the position at which to add the child

See Also:

ViewGroup.generateDefaultLayoutParams()

addView

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

Adds a child view with the specified layout parameters.

Parameters:

child - the child view to add

params - the layout parameters to set on the child

addView

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

Adds a child view with the specified layout parameters.

Overrides:

addView in class ViewGroup

Parameters:

child - the child view to add

index - the position at which to add the child

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 overriden 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 the superclass' View.onMeasure(int, int) 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 View.onMeasure(int, int) to provide better measurements of their content.

If this method is overridden, it is the subclass's responsibility to make sure the measured height and width are at least the view's minimum height and width (View.getSuggestedMinimumHeight() and View.getSuggestedMinimumWidth()).

Overrides:

onMeasure in class LinearLayout

Parameters:

widthMeasureSpec - horizontal space requirements as imposed by the parent. The requirements are encoded with View.MeasureSpec.

heightMeasureSpec - vertical space requirements as imposed by the parent. The requirements are encoded with View.MeasureSpec.

See Also:

View.getMeasuredWidth(), View.getMeasuredHeight(), View.setMeasuredDimension(int, int), View.getSuggestedMinimumHeight(), View.getSuggestedMinimumWidth(), View.MeasureSpec.getMode(int), View.MeasureSpec.getSize(int)

onLayout

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

Called from layout 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 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

measureChildBeforeLayout

void measureChildBeforeLayout(View child,
                              int childIndex,
                              int widthMeasureSpec,
                              int totalWidth,
                              int heightMeasureSpec,
                              int totalHeight)

Measure the child according to the parent's measure specs. This method should be overriden by subclasses to force the sizing of children. This method is called by LinearLayout.measureVertical(int, int) and LinearLayout.measureHorizontal(int, int).

Overrides:

measureChildBeforeLayout in class LinearLayout

Parameters:

child - the child to measure

childIndex - the index of the child in this view

widthMeasureSpec - horizontal space requirements as imposed by the parent

totalWidth - extra space that has been used up by the parent horizontally

heightMeasureSpec - vertical space requirements as imposed by the parent

totalHeight - extra space that has been used up by the parent vertically

measureVertical

void measureVertical(int widthMeasureSpec,
                     int heightMeasureSpec)

Measures the children when the orientation of this LinearLayout is set to LinearLayout.VERTICAL.

Overrides:

measureVertical in class LinearLayout

Parameters:

widthMeasureSpec - Horizontal space requirements as imposed by the parent.

heightMeasureSpec - Vertical space requirements as imposed by the parent.

See Also:

LinearLayout.getOrientation(), LinearLayout.setOrientation(int), LinearLayout.onMeasure(int, int)

generateLayoutParams

public TableLayout.LayoutParams generateLayoutParams(AttributeSet attrs)

Returns a new set of layout parameters based on the supplied attributes set.

Overrides:

generateLayoutParams in class LinearLayout

Parameters:

attrs - the attributes to build the layout parameters from

Returns:

an instance of ViewGroup.LayoutParams or one of its descendants

checkLayoutParams

protected boolean checkLayoutParams(ViewGroup.LayoutParams p)

Overrides:

checkLayoutParams in class LinearLayout

generateLayoutParams

protected LinearLayout.LayoutParams generateLayoutParams(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(android.view.ViewGroup.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
