工具栏显示在顶部而不是底部

Question

我正在尝试 2个工具栏，一个位于顶部，另一个位于屏幕底部。目前最底层的仍显示在顶部。我该如何解决？

activity_main.xml中

         <?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"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:context="com.example.x.fresh.MainActivity">

<android.support.design.widget.AppBarLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:theme="@style/AppTheme.AppBarOverlay">

    <android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"
        android:background="?attr/colorPrimary"
        app:popupTheme="@style/AppTheme.PopupOverlay" />

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

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

<include
    layout="@layout/toolbar_bottom"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true"/>

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

toolbar_bottom.xml

<?xml version="1.0" encoding="utf-8"?>
  <android.support.v7.widget.Toolbar
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/toolbar2"
android:minHeight="?attr/actionBarSize"
android:background="@color/primary"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:popupTheme="@style/ThemeOverlay.AppCompat.Light"
app:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">

如果您没有使用relativeLayout，则android:layout_alignParentBottom="true"没有意义。

使用此

    <?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"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:context="com.example.x.fresh.MainActivity">

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

<android.support.design.widget.AppBarLayout
    android:id="@+id/appbar"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:theme="@style/AppTheme.AppBarOverlay">

    <android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"
        android:background="?attr/colorPrimary"
        app:popupTheme="@style/AppTheme.PopupOverlay" />

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



<include layout="@layout/content_main"
           android:layout_below="@+id/appbar"
            android:id="@+id/content"/>

<include
    layout="@layout/toolbar_bottom"
    android:layout_below="@+id/content"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true"/>

</RelativeLayout>

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

嗨请在示例

下面

<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true">

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

        <android.support.design.widget.AppBarLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content">

            <android.support.v7.widget.Toolbar
                android:id="@+id/toolbar"
                android:layout_width="match_parent"
                android:layout_height="?attr/actionBarSize"
                android:background="?attr/colorPrimary"/>

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


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

        <include
            android:id="@+id/bottombar"
            layout="@layout/custom_toolbar"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_alignParentBottom="true"/>
    </RelativeLayout>
</android.support.design.widget.CoordinatorLayout>

只需添加相对布局
