* AttachedSurfaceControl: Respond to API feedback.Robert Carr2021-05-051-53/+0
| | | | | | | | | | | "Root" is eliminated from the interface name as it is a property of the object and not the interface, but remains highlighted in the getters to express the relationship between the called and returned object. Bug: 185365821 Test: Existing tests pass Change-Id: I163fc23f2c37c984ef3ffeb7514c4d8c1c1a3f90
* Expose API for using SurfaceControl with ViewRootImplRobert Carr2021-03-301-0/+53
| | | | | | | | | | | | This API is appropriately called "ViewRoot". So far we just expose an API surface to reparent SurfaceControl to the ViewRoot (but without exposing the ViewRoot's SurfaceControl, to encourage developers not to shoot themselves in the foot) and to synchronize with the drawing of the ViewRoot SurfaceControl.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Multiple threads are adding messages about the current state of the views to the main looper. This can cause onDetachedFromWindow to be posted on the looper before onAttachedToWindow. This change will make sure to only dispatch onDetachedFromWindow if we have previously dispatched onAttachToWindow. Change-Id: Ibc7cbcafb098bc000d2ef5480d2110d3fff4d55a
* | | Touch exploration feature, event bubling, refactorSvetoslav Ganov2011-04-221-0/+8

Added an Input Filter that interprets the touch screen motion events to perfrom accessibility exploration. One finger explores. Tapping within a given time and distance slop on the last exlopred location does click and long press, respectively. Two fingers close and in the same diretion drag. Multiple finglers or two fingers in different directions or two fingers too far away are delegated to the view hierarchy. Non moving fingers "accidentally grabbed the device for the scrren" are ignored. 2. Added accessibility events for hover enter, hover exit, touch exoloration gesture start, and end. Accessibility hover events are fired by the hover pipeline. An accessibility event is dispatched up the view tree and the topmost view fires it. Thus predecessors can augment the fired event. An accessibility event has several records and a predecessor can optionally modify, delete, and add such to the event. 3. Added onPopulateAccessibilityEvent and refactored the existing accessibility code to use it. 4. Added API for querying the currently enabled accessibility services by feedback type.

* | | Coalesce input events that arrive faster than 333Hz.Jeff Brown2011-04-071-10/+124
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some drivers report individual finger updates one at a time instead of all at once. When 10 fingers are down, this can cause the framework to have to handle 10 times as many events each with 10 times as much data. Applications like PointerLocation would get significantly bogged down by all of the redundant samples. This change coalesces samples that are closely spaced in time, before they are dispatched, as part of the motion event batching protocol. Increased the size of the InputChannel shared memory buffer so that applications can catch up faster if they accumulate a backlog of samples. Added logging code to help measure input dispatch and drawing latency issues in the view hierarchy. See ViewDebug.DEBUG_LATENCY. Change-Id: Ia5898f781f19901d2225c529a910c32bdf4f504f

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is due to the window doing a relayout after its activity is stopped, at which point it may need to interact with the adapter to load data. The fix here is to tell ViewRoot about an activity being stopped and, if in this state, hold off on doing any new measurements and layouts of the hierarchy until it is no longer stopped. In this case the relayout was happening due to the cursor being deactivated, with causes the adapter to invalidate its data. Because this is now in a dialog window, this allows the window to actually be resized smaller (unlike when in a full screen activity), and boom. Change-Id: I26442b4679819b4a4e6bc56289afd3445526750b
* | Add support for mouse hover and scroll wheel.Jeff Brown2011-02-251-31/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Dispatch ACTION_HOVER_MOVE and ACTION_SCROLL through the View hierarchy as onGenericTouchEvent. Pointer events dispatched this way are delivered to the view under the pointer. Non-pointer events continue to be delivered to the focused view. Added scroll wheel support to AbsListView, ScrollView, HorizontalScrollView and WebView. Shift+VSCROLL is translated to HSCROLL as appropriate. Added logging of new pointer events in PointerLocationView. Fixed a problem in EventHub when a USB device is removed that resulted in a long stream of ENODEV errors being logged until INotify noticed the device was gone. Note that the new events are not supported by wallpapers at this time because the wallpaper engine only delivers touch events. Make all mouse buttons behave identically. (Effectively we only support one button.) Change-Id: I9ab445ffb63c813fcb07db6693987b02475f3756

Added a new "axis" element to key layout files to specify the mapping between raw absolute axis values and motion axis ids. Expanded the axis bitfield to 64bits to allow for future growth. Modified the Makefile for keyboard prebuilts to run the keymap validation tool during the build. Added layouts for two game controllers. Added default actions for game pad button keys. Added more tests. Fixed a bunch of bugs. Change-Id: I73f9166c3b3c5bcf4970845b58088ad467525525

This broke an optimization in the ImageWallpaper. The old code happened to work because calling lockCanvas on the SurfaceHolder with a null dirty rectangle happened to have the side-effect of updating the SurfaceHolder's surface frame size field because it passed mSurfaceFrame as the dirty rect, causing mSurfaceFrame to be set to the size of the region to be drawn. However, relying on this side-effect is wrong. Among other things, the dirty region could actually be smaller than the surface frame. This patch fixes WallpaperService, SurfaceView and ViewRoot to ensure that the surface frame size is always set explicitly and is not modified by calls to lockCanvas.

This change makes the framework use display lists for all views in an application if hardware acceleration is enabled. In addition, display list renderering has been optimized so that any view's recreation of its own display list (which is necessary whenever the visuals of that view change) will not cause any other display list in its parent hierarchy to change. Instead, when there are any visual changes in the hierarchy, only those views which need to have new display list content will recreate their display lists. This optimization works by caching display list references in each parent display list (so the container of some child will refer to its child's display list by a reference to the child's display list). Then when a view needs to recreate its display list, it will do so inside the same display list object. This will cause the content to get refreshed, but not the reference to that content. Then when the view hierarchy is redrawn, it will automatically pick up the new content from the old reference. This optimization will not necessarily improve performance when applications need to update the entire view hierarchy or redraw the entire screen, but it does show significant improvements when redrawing only a portion of the screen, especially when the regions that are not refreshed are complex and time- consuming to redraw.
