<movable-area class="fixed-box">
            <movable-view  class="fixed-button" direction="all" :inertia="true" y="100px">
                
                <view class="menuBox">
                    <u-icon class="mainMenu" name="plus-circle" size="90" @click="declick"></u-icon>
                    <view class="posi" :animation="animationData">                      
                        <button style="background-color: transparent; display: inline-block; margin-top: 10rpx;" hover-class="none" open-type="contact">
                            <u-icon name="kefu-ermai" size="50"></u-icon>
                        </button>
                        <button style="background-color: transparent; display: inline-block; margin-top: 10rpx;" hover-class="none">
                            <u-icon name="map" size="50"></u-icon>
                        </button>
                        <button style="background-color: transparent; display: inline-block; margin-top: 10rpx;" hover-class="none">
                            <u-icon name="phone" size="50"></u-icon>
                        </button>                       
                    </view>
                </view>
            </movable-view>
        </movable-area>

上面使用的是uView插件的图标,也可以换成图片uni-app自带的<image>组件,内容可以根据自己需要替换。

<movable-area class="fixed-box">
            <movable-view  class="fixed-button" direction="all" :inertia="true" y="100px">              
                <view class="menuBox">
                    <image class="mainMenu" src="http://cdn.heijinka.vip/business_add.png" @click="declick"></image>
                    <view class="posi" :animation="animationData">                      
                        <button style="background-color: transparent; display: inline-block; margin-top: 10rpx;" hover-class="none" open-type="contact">
                            <image style="width: 50rpx; height: 50rpx;" src="http://cdn.heijinka.vip/business_my_photo.png" mode=""></image>
                        </button>
                        <image src="http://cdn.heijinka.vip/business_thumb.png" mode=""></image>
                        <image src="http://cdn.heijinka.vip/shop_call_phone.png" mode=""></image>                       
                    </view>
                </view>
            </movable-view>
        </movable-area>
