Class CardFrame

  ViewGroup
      android.support.wearable.view.CardFrame

public class CardFrame
extends ViewGroup

Wraps a view in a card-styled frame with a white background, rounded corners and a light drop-shadow. This layout is designed to be given a height of wrap_content within a container with a fixed height.

In most cases, developers will contain this view within a CardScrollView, or use a CardFragment which provides a CardFrame inside a CardScrollView.

Constructor Detail

CardFrame

CardFrame

public CardFrame(Context context,
                 AttributeSet attrs,
                 int defStyle)

Method Detail

setExpansionEnabled

public void setExpansionEnabled(boolean enabled)

Enables support contents which maybe be larger than the card's container. When expansion is enabled, and the contents are larger than the card, the top or bottom edge will fade to indicate this. The expansion factor must also be increased to allow the card to increase in height.

setExpansionDirection

public void setExpansionDirection(int direction)

Sets the direction in which content expands. Determines whether the top or bottom edge receives the fading edge appearance and whether more content is viewed by scrolling up or down, after increasing the expansion factor.

setExpansionFactor

public void setExpansionFactor(float expansionFactor)

Sets the allowed expansion amount as a multiple of the parent height. If expansion is enabled, the card will grow up to this height as needed to accommodate content.

getExpansionDirection

public int getExpansionDirection()

Returns the current expansion direction, either EXPAND_UP or EXPAND_DOWN.

isExpansionEnabled

public boolean isExpansionEnabled()

Indicates whether expansion is on. A CardFrame will increase in height up to expansionFactor times the parent view's height. When expansion is enabled, content which is taller than this will have a fading effect applied to the expanding edge, otherwise content is simply clipped.

getExpansionFactor

public float getExpansionFactor()

Returns the current expansionFactor which is the maximum height of this view as a multiple of the parent view's height.

onAttachedToWindow

protected void onAttachedToWindow()

onApplyWindowInsets

public WindowInsets onApplyWindowInsets(WindowInsets insets)

onMeasure

protected void onMeasure(int widthMeasureSpec,

getDefaultSize

                                    boolean greedy)

Get a default size, will be as small as possible unless forced by the parent, or greedy is specified.

onLayout

protected void onLayout(boolean changed,
                        int left,
                        int top,
