在CoordinatorLayout

Question

我在下面的代码中使用了CoordinatorLayout，这里我需要添加一个固定的页脚按钮，我尝试了但是在滚动按钮时也滚动到顶部。

<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.CardView xmlns:card_view="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    app:layout_behavior="@string/appbar_scrolling_view_behavior"
    card_view:cardElevation="@dimen/base_five_dp">

    <android.support.v7.widget.RecyclerView
        android:id="@+id/rvProperties"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />
</android.support.v7.widget.CardView>


<android.support.design.widget.AppBarLayout
    android:id="@+id/appBarLayout"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    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"
        app:contentScrim="?attr/colorPrimary"
        app:layout_scrollFlags="scroll|exitUntilCollapsed">

        <include layout="@layout/layout_visit_details" />

        <include layout="@layout/layout_tool_bar" />

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

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

尝试将按钮放在AppBarLayout之外和CoordinatorLayout内，如下所示：

<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.CardView xmlns:card_view="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    app:layout_behavior="@string/appbar_scrolling_view_behavior"
    card_view:cardElevation="@dimen/base_five_dp">

    <android.support.v7.widget.RecyclerView
        android:id="@+id/rvProperties"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />
</android.support.v7.widget.CardView>


<android.support.design.widget.AppBarLayout
    android:id="@+id/appBarLayout"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    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"
        app:contentScrim="?attr/colorPrimary"
        app:layout_scrollFlags="scroll|exitUntilCollapsed">

        <include layout="@layout/layout_visit_details" />

        <include layout="@layout/layout_tool_bar" />

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

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

<Button
    android:text="CIAOO"
    android:background="@color/colorAccent"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_gravity="bottom"/>

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

我认为这应该有用

您需要在关闭协调器布局标记之前添加布局！

   <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_weight="0">
        <Button
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:textColor="@android:color/white"
            android:layout_alignParentBottom="true"
            />
</RelativeLayout>

android:layout_height="match_parent"
android:fitsSystemWindows="true">

<RelativeLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_above="@+id/btn_bottom">

        <android.support.v7.widget.CardView xmlns:card_view="http://schemas.android.com/apk/res-auto"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            app:layout_behavior="@string/appbar_scrolling_view_behavior"
            card_view:cardElevation="@dimen/base_five_dp">

            <android.support.v7.widget.RecyclerView

                android:layout_height="match_parent" />
        </android.support.v7.widget.CardView>


        <android.support.design.widget.AppBarLayout
            android:id="@+id/appBarLayout"

            android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">

            <android.support.design.widget.CollapsingToolbarLayout

                 <include layout="@layout/layout_tool_bar" />

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

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

    <Button

        android:text="BUTTON" />
</RelativeLayout>
</android.support.design.widget.CoordinatorLayout>
