Question

除广告外，我想要完整的屏幕滚动功能。但该列表视图显示了一个项目，如果高度是填充内容或包装内容。仅列出该场景中的视图滚动。

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

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

    <LinearLayout
        android:orientation="vertical"
        app:layout_behavior="@string/appbar_scrolling_view_behavior"
        android:layout_width="match_parent"
        android:layout_height="match_parent">

        <ListView
            android:id="@+id/list_view"
            android:layout_width="fill_parent"
            android:layout_height="match_parent"
            app:layout_behavior="@string/appbar_scrolling_view_behavior"/>
    </LinearLayout>
</android.support.design.widget.CoordinatorLayout>

我尝试了填充内容/包装内容，但没有任何效果。

我在列表视图中有超过50个项目，但我也想用线性布局滚动屏幕。

感谢。

在Android中的ScrollView中使用ListLayout的LinearLayout
