CollapsingToolbarLayout与GridView的问题

Question

CollapsingToolbarLayout只有有工作RecyclerView但不与工作ListView和GridView.

下面是我的XML文件:

<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.design.widget.AppBarLayout
        android:id="@+id/appbar"
        android:layout_width="match_parent"
        android:layout_height="192dp"
        android:fitsSystemWindows="true"
        android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">

        <android.support.design.widget.CollapsingToolbarLayout
            android:id="@+id/collapsing_toolbar"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:fitsSystemWindows="true"
            app:contentScrim="?attr/colorPrimary"
            app:expandedTitleMarginBottom="32dp"
            app:expandedTitleMarginEnd="64dp"
            app:expandedTitleMarginStart="48dp"
            app:layout_scrollFlags="scroll|exitUntilCollapsed">

            <ImageView
                android:id="@+id/restaurant_image"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:src="@drawable/gradiant"
                app:layout_collapseMode="parallax" />

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

    <android.support.v4.widget.NestedScrollView 
       android:layout_width="match_parent"
       android:layout_height="match_parent"
       android:animateLayoutChanges="true"
       app:layout_behavior="@string/appbar_scrolling_view_behavior"
       android:fillViewport="true">


    <GridView
        android:id="@+id/restaurant_items"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_marginLeft="20dp"
        android:layout_marginRight="20dp"
        android:layout_marginTop="5dp"
        app:layout_behavior="@string/appbar_scrolling_view_behavior"
        android:gravity="center"
        android:numColumns="2"
        android:verticalSpacing="20dp" />

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

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

这个是我的Activity档案:

        Toolbar toolbar = (Toolbar) findViewById(R.id.anim_toolbar);
        setSupportActionBar(toolbar);
        getSupportActionBar().setDisplayHomeAsUpEnabled(true);
        CollapsingToolbarLayout collapsingToolbar = (CollapsingToolbarLayout) findViewById(R.id.collapsing_toolbar);
        collapsingToolbar.setTitle("Resturant Name");
        ImageView header = (ImageView) findViewById(R.id.restaurant_image);

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
            ViewCompat.setNestedScrollingEnabled(mGrid,true);
        }

        mGrid.setAdapter(new ResturantItemsAdapter(this, images, name));//images and name is array with size 10....

注意:-Scrolling工作正常但是在一些网格视图列表滚动之后它会卡住而不是滚动更多,即使网格视图中有更多行.它仅滚动网格视图的第8项,第9项和第10项未显示...

我搜索了许多链接,有人说它只能在上面和Lollipop版本中工作.下面的版本有一些问题.

是否可以在棒棒糖版本下运行折叠工具栏？

谢谢大家 ....

CoordinatorLayout用RecyclerView或更好地工作NestedScrollView.为了您的要求,您可以使用RecyclerView与GridLayoutManger.

<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.design.widget.AppBarLayout
        android:id="@+id/appbar"
        android:layout_width="match_parent"
        android:layout_height="192dp"
        android:fitsSystemWindows="true"
        android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">

        <android.support.design.widget.CollapsingToolbarLayout
            android:id="@+id/collapsing_toolbar"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:fitsSystemWindows="true"
            app:contentScrim="?attr/colorPrimary"
            app:expandedTitleMarginBottom="32dp"
            app:expandedTitleMarginEnd="64dp"
            app:expandedTitleMarginStart="48dp"
            app:layout_scrollFlags="scroll|exitUntilCollapsed">

            <ImageView
                android:id="@+id/restaurant_image"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:src="@drawable/gradiant"
                app:layout_collapseMode="parallax" />

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

  <android.support.v7.widget.RecyclerView
    android:id="@+id/my_recycler_view"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    app:layout_behavior="@string/appbar_scrolling_view_behavior"
    android:scrollbars="vertical" />

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

RecyclerView.LayoutManager mLayoutManager = new GridLayoutManager(this, 2); recyclerView.setLayoutManager(mLayoutManager);

以下示例演示了以下内容的使用GridLayoutManger:http: //www.androidhive.info/2016/05/android-working-with-card-view-and-recycler-view/

您需要将GridView和ListView包装在NestedScrollView中并添加正确的行为,如下所示:

<android.support.v4.widget.NestedScrollView 
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:animateLayoutChanges="true"
    app:layout_behavior="@string/appbar_scrolling_view_behavior"
    android:fillViewport="true">
