我有一个nativescript xml视图,定义如下:
<Page
xmlns="http://schemas.nativescript.org/tns.xsd"
xmlns:menu="components/menu"
xmlns:header="components/header"
loaded="loaded">
<header:header />
<StackLayout orientation="vertical">
<ScrollView>
<GridLayout rows="auto,auto,auto,auto" cols="auto,auto" >
<Image row="0" colSpan="2" src="~/img/tap.png" tap="takePicture"/>
...
<TextField row="2" col="1" horizontalAlignment="right" />
<Button row="3" colSpan="2" text="UPLOAD" />
</GridLayout>
</ScrollView>
<menu:menu />
</StackLayout>
</Page>
GridLayout太大而无法包含在单个屏幕中,因此我将其包装在ScrollView中。然而,这不起作用:我无法滚动页面,因此,无法访问TextField和Button等最后的UI元素。 我究竟做错了什么?我应该将ScrollView标签插入不同的位置吗?
答案 0 :(得分:4)
尝试在StackLayout中包装GridLayout。认为问题可能是ScrollView很难计算其滚动高度,因为GridLayout具有&#34; auto&#34; cols和rows。
<ScrollView>
<StackLayout>
<GridLayout rows="auto,auto,auto,auto" cols="auto,auto" >
<Image row="0" colSpan="2" src="~/img/tap.png" tap="takePicture"/>
...
<TextField row="2" col="1" horizontalAlignment="right" />
<Button row="3" colSpan="2" text="UPLOAD" />
</GridLayout>
</StackLayout>
</ScrollView>
