将FAB放在碎片中 [英] Place a FAB in a Fragment

问题描述

下午好，

我正在尝试将FAB放在片段的底部，但是我不知道可以在哪里放置它.

I am trying to put a FAB at the bottom|end of a fragment, but I do not know where I can place it.

这是Fragment的xml代码:

Here is the Fragment's xml code :

<android.support.v4.widget.SwipeRefreshLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/swipe_container"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <android.support.design.widget.CoordinatorLayout
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/cars_list_content"
        android:layout_width="match_parent"
        android:layout_height="match_parent">

            <LinearLayout
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:orientation="vertical"
                android:id="@+id/scrollable_layout">
                <include layout="@layout/write_comment"/>

                <android.support.v7.widget.RecyclerView
                    android:id="@+id/recyclerview"
                    android:layout_width="match_parent"
                    android:layout_height="match_parent" />
            </LinearLayout>
    </android.support.design.widget.CoordinatorLayout>
</android.support.v4.widget.SwipeRefreshLayout>

还有FAB:

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

感谢您的帮助！

一个答案帮助我有了此代码的第一个解决方案":

An answer helped me to have a first "solution" with this code :

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

    <android.support.v4.widget.SwipeRefreshLayout xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:app="http://schemas.android.com/apk/res-auto"
        android:id="@+id/swipe_container"
        android:layout_width="match_parent"
        android:layout_height="match_parent">

        <android.support.design.widget.CoordinatorLayout
            xmlns:android="http://schemas.android.com/apk/res/android"
            android:id="@+id/cars_list_content"
            android:layout_width="match_parent"
            android:layout_height="match_parent">

                <LinearLayout
                    android:layout_width="match_parent"
                    android:layout_height="match_parent"
                    android:orientation="vertical"
                    android:id="@+id/scrollable_layout">
                    <include layout="@layout/write_comment"/>

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

                </LinearLayout>
        </android.support.design.widget.CoordinatorLayout>
    </android.support.v4.widget.SwipeRefreshLayout>

    <android.support.design.widget.FloatingActionButton
        android:id="@+id/fab"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="end|bottom"
        android:layout_margin="@dimen/fab_margin"
        android:src="@drawable/ic_plus"
        android:layout_alignParentBottom="true"
        android:layout_alignParentRight="true"
        android:layout_alignParentEnd="true"/>
</RelativeLayout>

但是它不能正常工作:

尝试一下:

<?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">

    <android.support.v4.widget.SwipeRefreshLayout xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:app="http://schemas.android.com/apk/res-auto"
        android:id="@+id/swipe_container"
        android:layout_width="match_parent"
        android:layout_height="match_parent">

        <android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
            android:id="@+id/cars_list_content"
            android:layout_width="match_parent"
            android:layout_height="match_parent">

            <LinearLayout
                android:id="@+id/scrollable_layout"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:orientation="vertical">


                <android.support.v7.widget.RecyclerView
                    android:id="@+id/recyclerview"
                    android:layout_width="match_parent"
                    android:layout_height="match_parent" />
            </LinearLayout>
        </android.support.design.widget.CoordinatorLayout>
    </android.support.v4.widget.SwipeRefreshLayout>

    <android.support.design.widget.FloatingActionButton
        android:id="@+id/fab_add"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:layout_alignParentLeft="true"
        android:layout_margin="@dimen/fab_margin"
        android:src="@drawable/ic_photo_camera_white"
        app:backgroundTint="@color/colorFabButton" />
</RelativeLayout>
