好的,我知道这是重复的,但是我发现没有解决方案没有用。我不知道问题是什么,为什么它不起作用。我希望BottomNavigationView在向下滚动gridv时隐藏,而在向上滚动时显示。有人可以帮忙吗?
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".layout.HomeActivity">
<androidx.swiperefreshlayout.widget.SwipeRefreshLayout
android:id="@+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent">
<GridView
android:id="@+id/gridLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:numColumns="2"
android:scrollbars="none" />
</androidx.swiperefreshlayout.widget.SwipeRefreshLayout>
<com.google.android.material.bottomnavigation.BottomNavigationView
android:layout_alignParentBottom="true"
app:layout_behavior="@string/hide_bottom_view_on_scroll_behavior"
android:id="@+id/bottom_menu"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:itemIconTint="@drawable/clicl_menu"
app:itemTextColor="@drawable/clicl_menu"
app:menu="@menu/bottom_menu"/>
</RelativeLayout>

我会用CoordinatorLayout
和app:layout_scrollFlags
来做到这一点:
<androidx.coordinatorlayout.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".layout.HomeActivity">
<androidx.swiperefreshlayout.widget.SwipeRefreshLayout
android:id="@+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent">
<GridView
android:id="@+id/gridLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:numColumns="2"
android:scrollbars="none" />
</androidx.swiperefreshlayout.widget.SwipeRefreshLayout>
<com.google.android.material.bottomnavigation.BottomNavigationView
android:layout_alignParentBottom="true"
android:id="@+id/bottom_menu"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:layout_scrollFlags="scroll|enterAlways"
app:itemIconTint="@drawable/clicl_menu"
app:itemTextColor="@drawable/clicl_menu"
app:menu="@menu/bottom_menu"/>
</androidx.coordinatorlayout.widget.CoordinatorLayout>
