问题

以下是翻译好的内容：

我需要帮助来制作表格列表视图中的标题，我尝试了很多次，但是标题与表格列不一样，我的意思是不够整齐...

这是我的 XML 代码：

activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity">
    <HorizontalScrollView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginStart="8dp"
        android:layout_marginLeft="8dp"
        android:layout_marginTop="8dp"
        android:layout_marginEnd="8dp"
        android:layout_marginRight="8dp">
    <ListView
        android:id="@+id/list"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        />
    </HorizontalScrollView>
    </RelativeLayout>

list_item.xml

# 答案1
**得分**: 1
为每个在一行中的 `TextView` 添加一些权重
android:layout_weight="1"
这将使所有的视图具有相等的宽度，并且都适应于 `LinearLayout` 中。你也可以为其中一列添加权重为 2 或更多，以增加该列的空间。
或者使用 [GridView][1]，甚至更好地使用 [TableLayout][2]，这个类专门用于构建这种结构（表格）。

<summary>英文:</summary>
add some weight for every `TextView` you have in a row
android:layout_weight=&quot;1&quot;
this will make all your views equal width and all will fit inside `LinearLayout`. you may also add weight = 2 or more for adding more space for one of columns
or use [GridView][1] or even better [TableLayout][2], this class is intended to build such constructions (tables)
