From 3e6e72d4b839fcb1e55e03ea701257df98e3129a Mon Sep 17 00:00:00 2001 From: Mugurell Date: Tue, 6 Jul 2021 15:58:13 +0300 Subject: [PATCH] For #10555 - Use INPUT_HANDLING_UNKNOWN as the default of InputResultDetail We need to wait until having a response from GeckoView on how it handled the touch only after which we'll know whether to animate the toolbar or not. The edgecase scenario of having pull to refresh enabled even before having a response from GeckoView will still work because "canOverscrollTop()" only checks for the touch to not be handled by the browser to pan the page. --- .../behavior/BrowserToolbarBehavior.kt | 2 +- .../concept/engine/InputResultDetail.kt | 17 +++++- .../concept/engine/InputResultDetailTest.kt | 59 ++++++++++++++----- docs/changelog.md | 3 + 4 files changed, 63 insertions(+), 18 deletions(-) diff --git a/components/browser/toolbar/src/main/java/mozilla/components/browser/toolbar/behavior/BrowserToolbarBehavior.kt b/components/browser/toolbar/src/main/java/mozilla/components/browser/toolbar/behavior/BrowserToolbarBehavior.kt index b00ce2a653c..167cd030773 100644 --- a/components/browser/toolbar/src/main/java/mozilla/components/browser/toolbar/behavior/BrowserToolbarBehavior.kt +++ b/components/browser/toolbar/src/main/java/mozilla/components/browser/toolbar/behavior/BrowserToolbarBehavior.kt @@ -201,7 +201,7 @@ class BrowserToolbarBehavior( browserToolbar?.let { toolbar -> if (shouldScroll && startedScroll) { yTranslator.translate(toolbar, distance) - } else { + } else if (engineView?.getInputResultDetail()?.isTouchHandlingUnknown() == false) { // Force expand the toolbar if the user scrolled up, it is not already expanded and // an animation to expand it is not already in progress, // otherwise the user could get stuck in a state where they cannot show the toolbar diff --git a/components/concept/engine/src/main/java/mozilla/components/concept/engine/InputResultDetail.kt b/components/concept/engine/src/main/java/mozilla/components/concept/engine/InputResultDetail.kt index 6cf982a94e8..f84dfec221e 100644 --- a/components/concept/engine/src/main/java/mozilla/components/concept/engine/InputResultDetail.kt +++ b/components/concept/engine/src/main/java/mozilla/components/concept/engine/InputResultDetail.kt @@ -7,8 +7,12 @@ package mozilla.components.concept.engine import android.view.MotionEvent import androidx.annotation.VisibleForTesting -// The below top-level values are following the same from [org.mozilla.geckoview.PanZoomController] +/** + * Don't yet have a response from the browser about how the touch was handled. + */ +const val INPUT_HANDLING_UNKNOWN = -1 +// The below top-level values are following the same from [org.mozilla.geckoview.PanZoomController] /** * The content has no scrollable element. * @@ -99,7 +103,7 @@ internal const val OVERSCROLL_DIRECTIONS_VERTICAL = 1 shl 1 * - whether the event can overscroll the page and in what direction. * * @param inputResult Indicates who will use the current [MotionEvent]. - * Possible values: [[INPUT_UNHANDLED], [INPUT_HANDLED], [INPUT_HANDLED_CONTENT]]
