  • 第二十一篇-表格布局和约束布局

    将手机桌面划分区域,进行表格布局。

    效果图:

    layout.xml

    <?xml version="1.0" encoding="utf-8"?>
    <TableLayout xmlns:android="http://schemas.android.com/apk/res/android"

    </TableLayout>
    View Code

    图片可以自行在网上下载。放在res下面的mipmap-xhdpi,当然,其他几个放图片的地方也是可以存放的。

    进行约束布局

    效果图:

    整个界面分为两部分,上和下,为线性布局,两张图片,其实这两张图片可以合起来连成一个背景。看起来就像是一张图片一样。比例为1:2

    下面这张图片里面为约束布局,包含5张小图标,分别为进入,设置,帮助,退出,风云榜。
