我是nativescript的新手。我刚刚完成了教程,并且能够制作具有ScrollView的应用程序的准系统:
<ScrollView (scroll)="onScroll($event)">
<GridLayout class="m-15" rows="auto auto auto auto auto auto auto auto auto auto auto auto auto auto auto auto">
<Label class="h3 m-5" height="50" row="0" text="Title 1"></Label>
<Image class="h3 m-5" row="1" src="https://play.nativescript.org/dist/assets/img/NativeScript_logo.png" height="80" width="80"></Image>
<Label class="h3 m-5" height="50" row="2" text="Title 3"></Label>
<Label class="h3 m-5" height="50" row="3" text="Title 4"></Label>
<Label class="h3 m-5" height="50" row="4" text="Title 5"></Label>
<Label class="h3 m-5" height="50" row="5" text="Title 6"></Label>
<Label class="h3 m-5" height="50" row="6" text="Title 7"></Label>
<Label class="h3 m-5" height="50" row="7" text="Title 8"></Label>
<Label class="h3 m-5" height="50" row="8" text="Title 9"></Label>
<Label class="h3 m-5" height="50" row="9" text="Title 10"></Label>
<Label class="h3 m-5" height="50" row="10" text="Title 10"></Label>
<Label class="h3 m-5" height="50" row="11" text="Title 11"></Label>
<Label class="h3 m-5" height="50" row="12" text="Title 12"></Label>
<Label class="h3 m-5" height="50" row="13" text="Title 13"></Label>
<Label class="h3 m-5" height="50" row="14" text="Title 14"></Label>
<Label class="h3 m-5" height="50" row="15" text="Title 15"></Label>
</GridLayout>
</ScrollView>
但是,我想这样做,以便这些元素在2列网格中,但我无法弄清楚如何在不崩溃应用程序的情况下执行此操作。有人可以帮帮我吗?
在GridLayout中的行中,你在auto
和两列之间缺少逗号,你需要添加columns
参数,例如asterisks
或numbers
或auto
<GridLayout class="m-15" columns="*,*" rows="auto, auto, auto, auto, auto, auto, auto, auto, auto, auto, auto, auto, auto, auto, auto, auto">
并且在GridLayout内部的元素中添加col="0"
或col="1"
,如果它是第一列或第二列
<Label class="h3 m-5" height="50" col="0" row="2" text="Title 3"></Label> //third row, first column
<Label class="h3 m-5" height="50" col="1" row="2" text="Title 4"></Label> //third row, second column
