  • shouldDelayChildPressedState

    public boolean shouldDelayChildPressedState()

    Description copied from class: ViewGroup
    Return true if the pressed state should be delayed for children or descendants of this ViewGroup. Generally, this should be done for containers that can scroll, such as a List. This prevents the pressed state from appearing when the user is actually trying to scroll the content. The default implementation returns true for compatibility reasons. Subclasses that do not scroll should generally override this method and return false.

    Overrides:

    shouldDelayChildPressedState in class ViewGroup

    true when widgets are baseline-aligned, false otherwise

  • setBaselineAligned

    public void setBaselineAligned(boolean baselineAligned)

    Defines whether widgets contained in this layout are baseline-aligned or not.

    Parameters:

    baselineAligned - true to align widgets on their baseline, false otherwise

  • isMeasureWithLargestChildEnabled

    public boolean isMeasureWithLargestChildEnabled()

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

    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.

  • setBaselineAlignedChildIndex

    public void setBaselineAlignedChildIndex(int i)

    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

  • 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 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 View

    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)

  • 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 l,
                int t,
                int r,
                int b)

    Description copied from class: ViewGroup
    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 children.

    Specified by:

    onLayout in class ViewGroup

    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

  • setOrientation

    public void setOrientation(int orientation)

    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)

    Parameters:

    gravity - See Gravity

  • setHorizontalGravity

    public void setHorizontalGravity(int horizontalGravity)

  • setVerticalGravity

    public void setVerticalGravity(int verticalGravity)

  • generateLayoutParams

    public LinearLayout.LayoutParams generateLayoutParams(AttributeSet attrs)

    Description copied from class: ViewGroup
    Returns a new set of layout parameters based on the supplied attributes set.

    Overrides:

    generateLayoutParams in class ViewGroup

    Parameters:

    attrs - the attributes to build the layout parameters from

    Returns:

    an instance of ViewGroup.LayoutParams or one of its descendants

  • generateDefaultLayoutParams

    protected LinearLayout.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 or null

  • generateLayoutParams

    protected LinearLayout.LayoutParams generateLayoutParams(ViewGroup.LayoutParams p)

    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(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 ViewGroup

    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

  • checkLayoutParams

    protected boolean checkLayoutParams(ViewGroup.LayoutParams p)

    Description copied from class: ViewGroup

    Overrides:

    checkLayoutParams in class ViewGroup

  • onInitializeAccessibilityEvent

    public void onInitializeAccessibilityEvent(AccessibilityEvent event)

    Description copied from class: View
    Initializes an AccessibilityEvent with information about this View which is the event source. In other words, the source of an accessibility event is the view whose state change triggered firing the event.

    Example: Setting the password property of an event in addition to properties set by the super implementation:

     public void onInitializeAccessibilityEvent(AccessibilityEvent event) {
         super.onInitializeAccessibilityEvent(event);
         event.setPassword(true);
     }

    If an View.AccessibilityDelegate has been specified via calling View.setAccessibilityDelegate(AccessibilityDelegate) its View.AccessibilityDelegate.onInitializeAccessibilityEvent(View, AccessibilityEvent) is responsible for handling this call.

    Note: Always call the super implementation before adding information to the event, in case the default implementation has basic information to add.

    Overrides:

    onInitializeAccessibilityEvent in class View

    Parameters:

    event - The event to initialize.

    See Also:

    View.sendAccessibilityEvent(int), View.dispatchPopulateAccessibilityEvent(AccessibilityEvent)

  • onInitializeAccessibilityNodeInfo

    public void onInitializeAccessibilityNodeInfo(AccessibilityNodeInfo info)

    Description copied from class: View
    Initializes an AccessibilityNodeInfo with information about this view. The base implementation sets:

    • AccessibilityNodeInfo.setParent(View),
    • AccessibilityNodeInfo.setBoundsInParent(Rect),
    • AccessibilityNodeInfo.setBoundsInScreen(Rect),
    • AccessibilityNodeInfo.setPackageName(CharSequence),
    • AccessibilityNodeInfo.setClassName(CharSequence),
    • AccessibilityNodeInfo.setContentDescription(CharSequence),
    • AccessibilityNodeInfo.setEnabled(boolean),
    • AccessibilityNodeInfo.setClickable(boolean),
    • AccessibilityNodeInfo.setFocusable(boolean),
    • AccessibilityNodeInfo.setFocused(boolean),
    • AccessibilityNodeInfo.setLongClickable(boolean),
    • AccessibilityNodeInfo.setSelected(boolean),

    Subclasses should override this method, call the super implementation, and set additional attributes.

    If an View.AccessibilityDelegate has been specified via calling View.setAccessibilityDelegate(AccessibilityDelegate) its View.AccessibilityDelegate.onInitializeAccessibilityNodeInfo(View, AccessibilityNodeInfo) is responsible for handling this call.

    Overrides:

    onInitializeAccessibilityNodeInfo in class View

    Parameters:

    info - The instance to initialize.
