25.1.0 Android支援lib正在破壞晶圓廠的行為

我升級到最新的支援庫版本,滾動FAB行為不起作用.當在RecyclerView上向下滾動時,它正確地向下滾動,但是當再次向上滾動時不是.它保持隱藏降級到25.0.1似乎減輕了這個問題.這裡提供的程式碼是我使用的程式碼.

<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"

android:layout_width="match_parent"
android:layout_height="match_parent"
android:animateLayoutChanges="true"
android:fitsSystemWindows="true"
tools:context=".mainhost.MainActivity"
tools:openDrawer="start">

<android.support.design.widget.CoordinatorLayout xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/activity_main_coordinator_layout_root_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".mainhost.MainActivity">

<android.support.design.widget.AppBarLayout
android:id="@+id/appbar_layout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="@style/AppTheme.AppBarOverlay">

<android.support.design.widget.CollapsingToolbarLayout
android:id="@+id/collapsing_toolbar_layout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:fitsSystemWindows="true"
app:contentScrim="?attr/colorPrimary"
app:layout_scrollFlags="scroll|enterAlways|snap">

<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
android:focusableInTouchMode="true"
app:layout_collapseMode="pin"
app:popupTheme="@style/AppTheme.PopupOverlay" />

</android.support.design.widget.CollapsingToolbarLayout>

</android.support.design.widget.AppBarLayout>

<!-- Layout for content is here. This can be a RelativeLayout-->

<FrameLayout
android:id="@+id/content_main"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginLeft="-3dp"
android:layout_marginRight="-3dp"
app:layout_behavior="@string/appbar_scrolling_view_behavior"
tools:context="com.globyworks.citykey.mainhost.MainActivity" />


<android.support.design.widget.FloatingActionButton
android:id="@+id/fab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom|end"
android:layout_margin="@dimen/fab_margin"
app:layout_behavior="com.globyworks.citykey.helpers.ScrollingFABBehavior"
android:src="@drawable/drawer_new_report_white" />

</android.support.design.widget.CoordinatorLayout>


<android.support.design.widget.NavigationView
android:id="@+id/navigation_view"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
android:background="@android:color/white"
app:menu="@menu/menu_drawer">

</android.support.design.widget.NavigationView>


</android.support.v4.widget.DrawerLayout>

和滾動類：

public class ScrollingFABBehavior extends FloatingActionButton.Behavior {


public ScrollingFABBehavior(Context context, AttributeSet attrs) {
super();
}

public boolean onStartNestedScroll(CoordinatorLayout parent, FloatingActionButton child, View directTargetChild, View target, int nestedScrollAxes) {

return true;
}

@Override
public boolean layoutDependsOn(CoordinatorLayout parent, FloatingActionButton child, View dependency) {
if (dependency instanceof RecyclerView) {
return true;
}

return false;
}

@Override
public void onNestedScroll(CoordinatorLayout coordinatorLayout,
FloatingActionButton child, View target, int dxConsumed,
int dyConsumed, int dxUnconsumed, int dyUnconsumed) {
super.onNestedScroll(coordinatorLayout, child, target, dxConsumed, dyConsumed,
dxUnconsumed, dyUnconsumed
);
if (dyConsumed > 0 && child.getVisibility() == View.VISIBLE) {
child.hide();
} else if (dyConsumed < 0 && child.getVisibility() != View.VISIBLE) {
child.show();
}
}
}

這裡的一個快速解決方法是在ofollow,noindex" target="_blank">end of the FAB’s hide animation 將FAB的可見性設定為INVISIBLE.

if (dyConsumed > 0 && child.getVisibility() == View.VISIBLE) {
child.hide(new FloatingActionButton.OnVisibilityChangedListener() {
@Override
public void onHidden(FloatingActionButton fab) {
super.onHidden(fab);
fab.setVisibility(View.INVISIBLE);
}
});
} else if (dyConsumed < 0 && child.getVisibility() != View.VISIBLE) {
child.show();
}
