我想让布局看起来像这样：

我已经放了一个按钮，但它不可见：

实际的 xml 文件是什么样的？这会更有帮助，但在看不到您的 xml 文件时，请确保所有按钮都在网格布局标签内。设置网格布局的宽度和高度以匹配父级，如果您想保留所有内容，甚至将列数和行数设置为 2 然后在您的按钮上，您必须在每个按钮上将 layout_columnweight 和 layout_rowweight 设置为 1，这样它们只占用 1网格上的部分。尝试从那个开始，就像我说的，如果你发布你的 xml 文件，我将能够告诉你到底出了什么问题它应该看起来像这样<GridLayout xmlns:android="//schemas.android.com/apk/res/android"&nbsp; &nbsp; xmlns:app="//schemas.android.com/apk/res-auto"&nbsp; &nbsp; android:layout_width="match_parent"&nbsp; &nbsp; android:layout_height="match_parent"&nbsp; &nbsp; android:columnCount="2"&nbsp; &nbsp; android:rowCount="2">&nbsp; &nbsp; <Button&nbsp; &nbsp; &nbsp; &nbsp; android:layout_columnWeight="1"&nbsp; &nbsp; &nbsp; &nbsp; android:layout_rowWeight="1"&nbsp; &nbsp; &nbsp; &nbsp; android:background="#color you want"&nbsp; &nbsp; &nbsp; &nbsp; android:textSize="size you want"&nbsp; &nbsp; &nbsp; &nbsp; android:text="text you want" />&nbsp; &nbsp; <Button&nbsp; &nbsp; &nbsp; &nbsp; android:layout_columnWeight="1"&nbsp; &nbsp; &nbsp; &nbsp; android:layout_rowWeight="1"&nbsp; &nbsp; &nbsp; &nbsp; android:background="#color you want"&nbsp; &nbsp; &nbsp; &nbsp; android:textSize="size you want"&nbsp; &nbsp; &nbsp; &nbsp; android:text="text you want" />&nbsp; &nbsp; <Button&nbsp; &nbsp; &nbsp; &nbsp; android:layout_columnWeight="1"&nbsp; &nbsp; &nbsp; &nbsp; android:layout_rowWeight="1"&nbsp; &nbsp; &nbsp; &nbsp; android:background="#color you want"&nbsp; &nbsp; &nbsp; &nbsp; android:textSize="size you want"&nbsp; &nbsp; &nbsp; &nbsp; android:text="text you want" />&nbsp; &nbsp; <Button&nbsp; &nbsp; &nbsp; &nbsp; android:layout_columnWeight="1"&nbsp; &nbsp; &nbsp; &nbsp; android:layout_rowWeight="1"&nbsp; &nbsp; &nbsp; &nbsp; android:background="#color you want"&nbsp; &nbsp; &nbsp; &nbsp; android:textSize="size you want"&nbsp; &nbsp; &nbsp; &nbsp; android:text="text you want" /></GridLayout>

你可以用android:gravity=""属性来做，看下面的代码它认为它就像你想要的<?xml version="1.0" encoding="utf-8"?><GridLayoutandroid:layout_width="match_parent"android:layout_height="wrap_content"android:columnCount="2"><Button&nbsp; &nbsp; android:layout_width="0dp"&nbsp; &nbsp; android:layout_height="100dp"&nbsp; &nbsp; android:layout_columnWeight="1"&nbsp; &nbsp; android:gravity="center"&nbsp; &nbsp; android:layout_gravity="fill_horizontal"&nbsp; &nbsp; android:background="@color/colorAccent"&nbsp; &nbsp; android:text="Title1" />&nbsp; &nbsp; <Button&nbsp; &nbsp; &nbsp; &nbsp; android:layout_width="0dp"&nbsp; &nbsp; &nbsp; &nbsp; android:layout_height="100dp"&nbsp; &nbsp; &nbsp; &nbsp; android:layout_columnWeight="1"&nbsp; &nbsp; &nbsp; &nbsp; android:gravity="center"&nbsp; &nbsp; &nbsp; &nbsp; android:layout_gravity="fill_horizontal"&nbsp; &nbsp; &nbsp; &nbsp; android:background="@color/colorPrimaryDark"&nbsp; &nbsp; &nbsp; &nbsp; android:text="Title2" />&nbsp; &nbsp; &nbsp; &nbsp; <Button&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:layout_width="0dp"&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:layout_height="100dp"&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:layout_columnWeight="1"&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:gravity="center"&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:layout_gravity="fill_horizontal"&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:background="@color/colorPrimary"&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:text="Title3" />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <Button&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:layout_width="0dp"&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:layout_height="100dp"&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:layout_columnWeight="1"&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:gravity="center"&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:layout_gravity="fill_horizontal"&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:background="@color/colorAccent"&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:text="Title4" />&nbsp;</GridLayout>
