java.lang.Object
icyllis.modernui.view.ViewConfiguration
public class ViewConfiguration extends Object
Contains methods to standard constants used in the UI for timeouts, sizes, and distances.

  • Method Details

    • get

      @NonNull public static ViewConfiguration get(@NonNull Context context)
      Returns a configuration for the specified visual Context. The configuration depends on various parameters of the Context, like the dimension of the display or the density of the display.
      Returns:
      the view configuration

    • getScrollBarFadeDuration

      public static int getScrollBarFadeDuration()
      Returns:
      Duration of the fade when scrollbars fade away in milliseconds

    • getScrollDefaultDelay

      public static int getScrollDefaultDelay()
      Returns:
      Default delay before the scrollbars fade in milliseconds

    • getPressedStateDuration

      public static int getPressedStateDuration()
      Returns:
      the duration in milliseconds of the pressed state in child components.

    • getLongPressTimeout

      public static int getLongPressTimeout()
      Returns:
      the duration in milliseconds before a press turns into a long press

    • getTapTimeout

      public static int getTapTimeout()
      Returns:
      the duration in milliseconds we will wait to see if a touch event is a tap or a scroll. If the user does not move within this interval, it is considered to be a tap.

    • getScaledScrollbarSize

      public int getScaledScrollbarSize()
      Returns:
      The height of the horizontal scrollbar and the width of the vertical scrollbar in pixels

    • getScaledEdgeSlop

      public int getScaledEdgeSlop()
      Returns:
      Inset in pixels to look for touchable content when the user touches the edge of the screen

    • getScaledFadingEdgeLength

      public int getScaledFadingEdgeLength()
      Returns:
      the length of the fading edges in pixels

    • getScaledTouchSlop

      public int getScaledTouchSlop()
      Returns:
      Distance in pixels a touch can wander before we think the user is scrolling

    • getScaledHoverSlop

      public int getScaledHoverSlop()
      Returns:
      Distance in pixels a hover can wander while it is still considered "stationary".

    • getScaledMinScrollbarTouchTarget

      public int getScaledMinScrollbarTouchTarget()
      Returns:
      the minimum size of the scrollbar thumb's touch target in pixels

    • getScaledPagingTouchSlop

      public int getScaledPagingTouchSlop()
      Returns:
      Distance in pixels a touch can wander before we think the user is scrolling a full page

    • getScaledMinimumFlingVelocity

      public int getScaledMinimumFlingVelocity()
      Returns:
      Minimum velocity to initiate a fling, as measured in pixels per second.

    • getScaledMaximumFlingVelocity

      public int getScaledMaximumFlingVelocity()
      Returns:
      Maximum velocity to initiate a fling, as measured in pixels per second.

    • getScaledOverscrollDistance

      public int getScaledOverscrollDistance()
      Returns:
      The maximum distance a View should overscroll by when showing edge effects (in pixels).

    • getScaledOverflingDistance

      public int getScaledOverflingDistance()
      Returns:
      The maximum distance a View should overfling by when showing edge effects (in pixels).

    • getScaledVerticalScrollFactor

      public float getScaledVerticalScrollFactor()
      Returns:
      Amount to scroll in response to a vertical MotionEvent.ACTION_SCROLL event. Multiply this by the event's axis value to obtain the number of pixels to be scrolled.

    • getScaledHorizontalScrollFactor

      public float getScaledHorizontalScrollFactor()
      Returns:
      Amount to scroll in response to a horizontal MotionEvent.ACTION_SCROLL event. Multiply this by the event's axis value to obtain the number of pixels to be scrolled.

    • getScrollFriction

      public static float getScrollFriction()
      The amount of friction applied to scrolls and flings.
      Returns:
      A scalar dimensionless value representing the coefficient of friction.

    • getLongPressTooltipHideTimeout

      @Internal public static int getLongPressTooltipHideTimeout()
      Returns:
      the duration in milliseconds before an end of a long press causes a tooltip to be hidden

    • getHoverTooltipShowTimeout

      @Internal public static int getHoverTooltipShowTimeout()
      Returns:
      the duration in milliseconds before a hover event causes a tooltip to be shown

    • getHoverTooltipHideTimeout

      @Internal public static int getHoverTooltipHideTimeout()
      Returns:
      the duration in milliseconds before mouse inactivity causes a tooltip to be hidden.
