WebSettings settings = super.appView.getSettings();
settings.setBuiltInZoomControls(true);
settings.setDisplayZoomControls(true);
settings.setSupportZoom(true);

我可以缩放,但随着我的观点,离子标题栏和离子导航栏变焦.我尝试给标头css,以保持它固定：

position: fixed;
top: 0px;
left: 0px;

但是,它仍然会变焦.

我的index.html有一个ion-header-bar,它包含一个图像.
模板进入

<ion-nav-view class="has-header"></ion-nav-view>

我需要放大特定div的模板是’离子视图’,它看起来像：

<ion-view>
    <ion-nav-bar class="bar-stable">
        <ion-nav-buttons side="right">
            icon1
        </ion-nav-buttons>
        <ion-nav-buttons side="left">
            icon2
        </ion-nav-buttons>
    </ion-nav-bar>
    <div>
        Multiple divs in here,which are containers for html and css data we receive via AJAX requests. And this is here I need zooming in.
    </div>
</ion-view>

PS：如果我在离子视图中添加完整的HTML代码(带有Meta视口,没有标题,但是正文和div),这是否重要？
