public class LinearLayout
extends ViewGroup

A layout that arranges other views either horizontally in a single column or vertically in a single row.

Set setOrientation(int) to specify whether child views are displayed in a row or column.

To control how linear layout aligns all the views it contains, set a value for setGravity(int). For example, the snippet above sets android:gravity to "center". The value you set affects both horizontal and vertical alignment of all child views within the single row or column.

You can set LinearLayout.LayoutParams.weight on individual child views to specify how linear layout divides remaining space amongst the views it contains. See the Linear Layout guide for an example.

See LinearLayout.LayoutParams to learn about other attributes you can set on a child view to affect its position and size in the containing linear layout.

Returns:

True to measure children with a weight using the minimum size of the largest child, false otherwise.

setMeasureWithLargestChildEnabled

public void setMeasureWithLargestChildEnabled(boolean enabled)

When set to true, all children with a weight will be considered having the minimum size of the largest child. If false, all children are measured normally.

Disabled by default.

Parameters:

enabled - True to measure children with a weight using the minimum size of the largest child, false otherwise.

getBaseline

public int getBaseline()

Description copied from class: View

Return the offset of the widget's text baseline from the widget's top boundary. If this widget does not support baseline alignment, this method returns -1.

Overrides:

getBaseline in class View

Returns:

the offset of the baseline within the widget's bounds or -1 if baseline alignment is not supported

getBaselineAlignedChildIndex

public int getBaselineAlignedChildIndex()

Returns:

The index of the child that will be used if this layout is part of a larger layout that is baseline aligned, or -1 if none has been set.

Parameters:

i - The index of the child that will be used if this layout is part of a larger layout that is baseline aligned.

getWeightSum

public float getWeightSum()

Returns the desired weights sum.

Returns:

A number greater than 0.0f if the weight sum is defined, or a number lower than or equals to 0.0f if not weight sum is to be used.

setWeightSum

public void setWeightSum(float weightSum)

Defines the desired weights sum. If unspecified the weights sum is computed at layout time by adding the layout_weight of each child.

This can be used for instance to give a single child 50% of the total available space by giving it a layout_weight of 0.5 and setting the weightSum to 1.0.

Parameters:

weightSum - a number greater than 0.0f, or a number lower than or equals to 0.0f if the weight sum should be computed from the children's layout_weight

onDraw

protected void onDraw(@Nonnull
 Canvas canvas)

Description copied from class: View

Draw the content of this view, implement this to do your drawing.

Note that (0, 0) will be the top left of the bounds, and (width, height) will be the bottom right of the bounds.

Overrides:

onDraw in class View

Parameters:

canvas - the canvas to draw content

onMeasure

protected void onMeasure(int widthMeasureSpec,
 int heightMeasureSpec)

Description copied from class: View

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 View

Parameters:

widthMeasureSpec - width measure specification imposed by the parent MeasureSpec

heightMeasureSpec - height measure specification imposed by the parent MeasureSpec

hasDividerBeforeChildAt

protected boolean hasDividerBeforeChildAt(int childIndex)

Determines where to position dividers between children.

Parameters:

childIndex - Index of child to check for preceding divider

Returns:

true if there should be a divider before the child at childIndex

onLayout

protected void onLayout(boolean changed,
 int left,
 int top,
 int right,
 int bottom)

Description copied from class: View

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.

Specified by:

onLayout in class ViewGroup

Parameters:

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

left - Left position, relative to parent

top - Top position, relative to parent

right - Right position, relative to parent

bottom - Bottom position, relative to parent

onRtlPropertiesChanged

public void onRtlPropertiesChanged(int layoutDirection)

Description copied from class: View

Called when any RTL property (layout direction or text direction or text alignment) has been changed.

Subclasses need to override this method to take care of cached information that depends on the resolved layout direction, or to inform child views that inherit their layout direction.

The default implementation does nothing.

Overrides:

onRtlPropertiesChanged in class View

Parameters:

layoutDirection - the direction of the layout

See Also:

• View.LAYOUT_DIRECTION_LTR
• View.LAYOUT_DIRECTION_RTL

setOrientation

public void setOrientation(int orientation)

Should the layout be a column or a row.

Parameters:

orientation - Pass HORIZONTAL or VERTICAL. Default value is HORIZONTAL.

getOrientation

public int getOrientation()

Returns the current orientation.

Returns:

either HORIZONTAL or VERTICAL

setGravity

public void setGravity(int gravity)

Describes how the child views are positioned. Defaults to GRAVITY_TOP. If this layout has a VERTICAL orientation, this controls where all the child views are placed if there is extra vertical space. If this layout has a HORIZONTAL orientation, this controls the alignment of the children.

Parameters:

gravity - See Gravity

getGravity

public int getGravity()

Returns the current gravity. See Gravity

Returns:

the current gravity.

See Also:

• setGravity(int)

setHorizontalGravity

public void setHorizontalGravity(int horizontalGravity)

setVerticalGravity

public void setVerticalGravity(int verticalGravity)

generateLayoutParams

@Nonnull
protected ViewGroup.LayoutParams generateLayoutParams(@Nonnull
 ViewGroup.LayoutParams params)

Description copied from class: ViewGroup

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 ViewGroup

Parameters:

params - 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

generateDefaultLayoutParams

@Nonnull
protected ViewGroup.LayoutParams generateDefaultLayoutParams()

Returns a set of layout parameters with a width of ViewGroup.LayoutParams.MATCH_PARENT and a height of ViewGroup.LayoutParams.WRAP_CONTENT when the layout's orientation is VERTICAL. When the orientation is HORIZONTAL, the width is set to ViewGroup.LayoutParams.WRAP_CONTENT and the height to ViewGroup.LayoutParams.WRAP_CONTENT.

Overrides:

generateDefaultLayoutParams in class ViewGroup

Returns:

a set of default layout parameters

checkLayoutParams

protected boolean checkLayoutParams(@Nullable
 ViewGroup.LayoutParams params)

Description copied from class: ViewGroup

Check whether given params fit to this view group.

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

Overrides:

checkLayoutParams in class ViewGroup

Parameters:

params - layout params to check

Returns:

if params matched to this view group
