我想将 CollapsingToolbarLayoutRecyclerView 一起使用,例如 Whatsapp

这是捕获的视频:https://sendvid.com/0oi2lxx5

所以当我向上滚动时还可以,但是当我向下滚动时它就不流畅了。我想用 RecyclerView 平滑地滚动它。

这是我的 profile_activity.xml:

    <?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout
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:fitsSystemWindows="true">
<android.support.v7.widget.RecyclerView
android:layout_width="match_parent"
android:id="@+id/profile_recyclerview"
android:layout_height="match_parent"
app:layout_behavior="@string/appbar_scrolling_view_behavior"
android:layout_below="@+id/profileactivity_appbar" />

<android.support.design.widget.AppBarLayout
android:id="@+id/profileactivity_appbar"
android:layout_width="match_parent"
android:layout_height="400dp"
android:fitsSystemWindows="true"
android:theme="@style/AppTheme3.AppBarOverlay">

<android.support.design.widget.CollapsingToolbarLayout
android:id="@+id/profileactivity_collapsing_toolbar"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_scrollFlags="scroll|exitUntilCollapsed"
android:fitsSystemWindows="true"
app:contentScrim="?attr/colorPrimary"
app:expandedTitleMarginStart="48dp"
app:expandedTitleMarginEnd="64dp">

<ImageView
android:id="@+id/profileactivity_fullimage"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scaleType="centerCrop"
android:fitsSystemWindows="true"
app:layout_collapseMode="parallax"
app:layout_scrollFlags="scroll|enterAlways|enterAlwaysCollapsed" />

<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:popupTheme="@style/ThemeOverlay.AppCompat.Light"
app:layout_collapseMode="pin" />

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

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




<android.support.design.widget.FloatingActionButton
android:id="@+id/fab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="@dimen/fab_margin"
app:layout_anchor="@id/profileactivity_appbar"
app:layout_anchorGravity="bottom|right|end"
app:backgroundTint="@color/ColorPrimary"
android:src="@drawable/ic_create_white_48dp"/>

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

我正在使用:

compile 'com.android.support:appcompat-v7:23.4.0'
compile 'com.android.support:support-v4:23.4.0'
compile 'com.android.support:recyclerview-v7:23.4.0'
compile 'com.android.support:design:23.4.0'

我该如何解决这个问题?

最佳答案

好吧,我将解释如何解决问题,现在我的布局非常流畅;

Actually i dont know how its solved , but ;

  • 我删除了所有 android:fitsSystemWindows="true" 属性。
  • 然后将 app:layout_scrollFlags="scroll|enterAlways" 属性添加到 CollapsingToolbarLayoutImageViewToolbar
  • 并在 xml 中将所有元素移动到我的 AppBarLayout 之前。

我的 activity_profile.xml 喜欢:

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

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

content_profile_edit.xml 如下:

<!-- other views -->

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