This property is intended only for use because of the Fade changeover, which animates it to provide a visual translucency that doesn't facet-outcome (or get affected by) the true alpha house.
Extra choice which might be established to hold the best and/or base edges of the child clipped to its container's bounds. The clip might be according to the vertical gravity: a leading gravity will clip The underside edge, a bottom gravity will clip the very best edge, and neither will clip equally edges.
') of the subsequent continual values.
Specifies no matter if to filter touches in the event the view's window is obscured by A different seen window. android:fitsSystemWindows origin from which the y-coordinate is calculated. In a number of-display eventualities, the coordinate House can span screens.
String: A important specifying the kind of added information to add to the info. The additional data should be included into the Bundle returned by the information's AccessibilityNodeInfo#getExtras method. Never null.
This process was deprecated in API degree 28. The view drawing cache was mostly created obsolete Using the introduction of hardware-accelerated rendering in API 11. With hardware-acceleration, intermediate cache levels are mostly unneeded and can easily end in a Web decline in performance on account of the price of creating and updating the layer. In the uncommon scenarios in which caching levels are valuable, like for alpha animations, setLayerType(int, android.graphics.
Request to apply the given window insets to this view or A different view in its subtree. This method really should be identified as by consumers wishing to use insets equivalent to places obscured by window decorations or overlays.
Returns the presently configured Drawable for the thumb with the vertical scroll bar if it exists, null or else.
This consistent was deprecated in API level 28. The view drawing cache was largely produced obsolete Along with the introduction of components-accelerated rendering in API 11. With hardware-acceleration, intermediate cache layers are largely needless and can certainly cause a Web decline in functionality due to the cost of generating and updating the layer. In the scarce situations where by caching layers are beneficial, such as for alpha animations, setLayerType(int, android.graphics.
Structure is often a two move process: a measure go and also a format pass. The measuring go is carried out in measure(int, int) and is particularly a major-down traversal of your view tree. Just about every view pushes dimension requirements down the tree through the recursion. At the end of the evaluate move, each view has saved its measurements. The 2nd go takes place in layout(int, int, int, int) and is also major-down. For the duration of this pass Each individual guardian is answerable for positioning all of its kids utilizing the sizes computed during the measure go. Each time a view's measure() system returns, its getMeasuredWidth() and getMeasuredHeight() values should be established, in addition to Those people for all of that view's descendants. A view's measured width and calculated height values have to regard the constraints imposed by the view's moms and dads. This guarantees that at the conclusion of the measure pass, all mom and dad acknowledge all of their children's measurements. A dad or mum more info view could connect with measure() in excess of as soon as on its little ones. For instance, the mum or dad may measure Just about every child after with unspecified Proportions to find out how huge they wish to be, then call measure() on them once again with precise numbers In the event the sum of all the youngsters's unconstrained dimensions is too huge or far too small. The measure move works by using two lessons to speak dimensions. The MeasureSpec class is utilized by views to inform their moms and dads how they wish to be measured and positioned.
This class signifies a delegate that could be registered in the View to reinforce accessibility assistance by way of composition instead through inheritance. class
Views should also not provide fling velocities to nested mother or father views along an axis exactly where scrolling isn't now supported; a ScrollView shouldn't provide a horizontal fling velocity to its moms and dads considering that scrolling together that axis is not really permitted and carrying velocity alongside that motion will not seem sensible.
Buyer: accepts potential scroll capture targets; final results.take could possibly be referred to as zero or more instances on the contacting thread right before onScrollCaptureSearch returns This value cannot be null.
Rect: the obvious space of this ViewGroup in neighborhood coordinates, based on the guardian This benefit can not be null.}
