Question

我有3个动作按钮。一个扫描按钮和（如果某些条件被触发）另外两个“minifab”。扫描按钮应位于bottom|end位置，其他两个应位于其顶部。我使用自动生成的CustomView Android Studio给了我。现在我想知道如何改变我工厂的位置。我不能使用填充选项。这是因为CustomView？

这是我的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"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true"
    tools:context=".SlideMenu">

    <android.support.design.widget.AppBarLayout
        android:layout_height="wrap_content"
        android:layout_width="match_parent"
        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.support.design.widget.FloatingActionButton
        android:id="@+id/exportbutton"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="bottom|end"
        android:layout_margin="@dimen/fab_margin"
        android:src="@android:drawable/ic_menu_share"
        android:cropToPadding="false" />

    <android.support.design.widget.FloatingActionButton
        android:id="@+id/savebutton"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="bottom|end"
        android:layout_margin="@dimen/fab_margin"
        android:src="@android:drawable/ic_menu_save"
        android:cropToPadding="false" />

    <android.support.design.widget.FloatingActionButton
        android:id="@+id/scanbutton"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="bottom|end"
        android:layout_margin="@dimen/fab_margin"
        android:src="@android:drawable/ic_menu_add"
        android:visibility="visible" />

我认为这段代码对你有用我已经将CoOrdinate布局改为RelativeLayout而且每个按钮都会一个在另一个上面，你仍然可以通过给它填充来设置它

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    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=".SlideMenu">

    <android.support.design.widget.AppBarLayout
        android:layout_height="wrap_content"
        android:layout_width="match_parent"
        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.support.design.widget.FloatingActionButton
        android:id="@+id/exportbutton"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"

        android:src="@android:drawable/ic_menu_share"
        android:cropToPadding="false"
        android:layout_above="@+id/savebutton"
        android:layout_alignParentRight="true"
        android:layout_alignParentEnd="true" />

    <android.support.design.widget.FloatingActionButton
        android:id="@+id/savebutton"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"

        android:src="@android:drawable/ic_menu_save"
        android:cropToPadding="false"
        android:layout_above="@+id/scanbutton"
        android:layout_alignLeft="@+id/scanbutton"
        android:layout_alignStart="@+id/scanbutton" />

    <android.support.design.widget.FloatingActionButton
        android:id="@+id/scanbutton"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="bottom|end"
        android:src="@android:drawable/ic_menu_add"
        android:visibility="visible"
        android:layout_alignParentBottom="true"
        android:layout_alignParentRight="true"
        android:layout_alignParentEnd="true" />

</RelativeLayout>
