您的输入字段位于背景图像上方，您无法“看到”它，因为输入字段没有边框。这会在白色背景上留下纯白色输入字段。

将其添加到CSS中以查看输入字段的轮廓：

input{border:1px solid #000 !important;}

编辑：原来的问题对我来说并不清楚。 OP澄清了问题是输入字段的白色背景覆盖了背景图像。将背景转换为透明将解决此问题：.item{background-color:transparent !important;}

实例：

.item{background-color:transparent !important;}
input{border:1px solid #000 !important;}
.bar {
        position: relative!important
    }
    .bg {
        border: 1px solid red;
        background: url('https://d262ilb51hltx0.cloudfront.net/max/800/1*AJALCafqXhfLMG7iF7Ho0A.jpeg')!important;
        background-color: red!important;
        background-repeat: no-repeat!important;
        background-position: center!important;
        background-size: cover!important;
        
    }

        </ion-header-bar>
        <ion-content class="bg" style="position:absolute; left: 0; right: 0; top: 43px; bottom: 43px;">
            <label class="item item-input">
                <span class="input-label">Username</span>
                <input type="text">
            </label>
        </ion-content>
        <ion-footer-bar class=" bar bar-footer bar-positive" style="position:fixed!important">

为什么输入字段不在背景图像之上？
