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
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent"
android:layout_height="match_parent"
android:padding="16dp"
android:id="@+id/listItem"
android:orientation="horizontal">
<TextView
android:textColor="#000000"
android:text="Lokasi Berangkat"
android:id="@+id/depof1"
android:gravity="center"
android:layout_width="150dp"
android:layout_height="wrap_content"/>
<TextView
android:textColor="#000000"
android:text="Berangkat"
android:id="@+id/f1"
android:gravity="center"
android:layout_width="100dp"

**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="1"
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)
