Retrieve the general visible Display screen sizing wherein the window this view is hooked up to has actually been positioned in. This can take under consideration display screen decorations previously mentioned the window, for the two cases where by the window itself is being situation inside them or maybe the window is being placed below then and lined insets are used for the window to position its written content within.
, or until eventually a certain quantity of authentic time has elapsed. ultimate void wait around() Triggers The present thread to attend till it is actually awakened, normally by being notified
Returns the left padding of this view. If there are actually inset and enabled scrollbars, this benefit may include the Room required to Show the scrollbars likewise.
Return the quantity of offset applied to the remaining edge of the view's handwriting bounds, from the device of pixel.
Each time a person is navigating a consumer interface through directional keys such as a D-pad, it is necessary to give emphasis to actionable things for instance buttons Therefore the person can see what's going to just take enter. When the machine has touch capabilities, nevertheless, as well as person commences interacting Together with the interface by touching it, it's no longer necessary to often highlight, or give emphasis to, a specific view. This motivates a manner for interaction named 'touch mode'. For your touch able system, as soon as the consumer touches the display, the system will enter touch manner.
A Layout in which the positions of the youngsters might be described in relation to one another or to the mum or dad. ScrollView
Layout is often a two go course of action: a measure go along with a layout pass. The measuring go is implemented in evaluate(int, int) which is a leading-down traversal on the view tree. Each view pushes dimension specifications down the tree through the recursion. At the conclusion of the evaluate go, each and every view has saved its measurements. The 2nd go comes about in format(int, int, int, int) and is also top-down. Through this move each parent is chargeable for positioning all of its little ones utilizing the sizes computed in the evaluate go. Each time a view's measure() technique returns, its getMeasuredWidth() and getMeasuredHeight() values has to be set, together with Those people for all of that view's descendants. A view's calculated width and measured height values must respect the constraints imposed by the view's mom and dad. This ensures that at the conclusion of the evaluate move, all mom and dad settle for all in their children's measurements. A parent view may perhaps contact evaluate() a lot more than as soon as on its little ones. One example is, the guardian may evaluate Each individual kid as soon as with unspecified dimensions to Discover how massive they want to be, then simply call evaluate() on them yet again with precise numbers When the sum of all the children's unconstrained measurements is just too significant or also compact. The evaluate go employs two courses to speak Proportions. The MeasureSpec course is utilized by views to inform their mother and father how they wish to be calculated and positioned.
The view drawing cache was largely created out of date with the introduction of components-accelerated rendering in API 11. With components-acceleration, intermediate cache layers are largely avoidable and can easily end in a Internet reduction in efficiency due to the price of producing and updating the layer. Inside the exceptional conditions the place caching levels are helpful, which include for alpha animations, setLayerType(int, android.graphics.Paint) handles this with components rendering.
Dispatch a fling to a nested scrolling parent right before it truly is processed by this view. Nested pre-fling functions are to nested fling functions what touch intercept is to the touch and what nested pre-scroll should be to nested scroll.
Defines whether the horizontal scrollbar observe really should often be drawn. Could be a boolean price, like "genuine" or "Phony".
You'll want to steer clear of contacting this method when hardware acceleration is enabled. If you don't need to have the drawing cache bitmap, calling this technique will improve memory check here usage and result in the view to become rendered in computer software when, Consequently negatively impacting effectiveness.}
