我使用的是“KeyboardResizingAwareContentPage”页面,而不是“ContentPage”,因为在ios中,当键盘打开时,页面并没有设置。密码字段隐藏在键盘后面,这样用户在键入时就看不到任何内容。这就是我在IOs中使用Render for content Page的原因


如上所示,当我关注用户名或密码输入字段时,键盘后面隐藏着两个按钮。客户端的要求是,在那个时候页面应该是滚动的。我怎样才能解决这个问题?可以通过渲染吗?我在两个平台上都面临着这个问题。(ios和android)

即使您不想滚动页面,也可以使用滚动视图作为页面的根目录,并将网格放入其中


这应该可以解决问题。

检查:将网格放在ContentPageScrollView中。您得到解决方案了吗?是的,删除AppCompactIt's not working。(我使用网格是因为我的页面设计应该根据设备的高度来设置。页面不会以任何代价滚动,但现在客户端的要求是当键盘打开时页面应该滚动)。我给“*”和自动格式中的每一行指定高度。如果我把我的网格放在滚动视图中,我的网格就会混淆它应该有多高。所以我的设计不合适。
