用数据数组填充表 [英] Populating a table with an array of data

问题描述

我想建立一个表，该表具有固定的列数和X的行数，其中第一行列出了每一列的内容.例如，一列将是名称"，第二列将是年龄"，然后将有X数量的行用于存储数据.有什么方法可以在其他地方为此数据设置数组，并自动使用该数据创建/填充表的行.之前，我已经使用自定义适配器通过一个更简单的示例完成了此操作，但是我不确定如何在涉及的表中进行此操作.我感到很困惑，任何帮助将不胜感激.

I want to set up a table which has a fixed amount of columns, and an X amount of rows with The first row listing the contents of each column. For example, one column will be 'Name' and a second column will be 'Age', then there will be an X amount of rows which store the data. Is there any way that I can set up arrays for this data elsewhere, and automatically create/fill the rows of the table with this data. I've done this previously with a more simple example using a Custom Adapter but I'm not quite sure how to go about this with a table involved. I'm quite stuck and any help would be greatly appreciated.

推荐答案

ListView基本上充当任何数据表中的行.您应该使用要连续显示的所有属性创建一个POJO.您可以为数据创建一个自定义xml布局，该布局可能由与列对应的水平LinearLayout来完成.

A ListView basically acts as a row within any table of data. You should create a POJO with all the attributes you want to display in a row. You can create create a custom xml layout for the data, which would probably by a horizontal LinearLayout that corresponds to your columns.

POJO

public class MyData {
    public String Name;
    public int Age;
    // More data here
}

ListView项的布局(layout_list_item.xml)

ListView item layout (layout_list_item.xml)

<?xml version="1.0" encoding="utf-8"?>
    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:orientation="horizontal">

        <TextView
            android:id="@+id/Name"
            android:layout_height="wrap_content"
            android:layout_width="0dip"
            android:layout_weight="0.7" />

        <TextView
            android:id="@+id/Age"
            android:layout_height="wrap_content"
            android:layout_width="0dip"
            android:layout_weight="0.3" />

    </LinearLayout>

主要布局

<?xml version="1.0" encoding="utf-8"?>
    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:orientation="vertical">

        <LinearLayout
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:orientation="horizontal">

            <TextView
                android:layout_height="wrap_content"
                android:layout_width="0dip"
                android:layout_weight="0.7"
                android:text="Name" />

            <TextView
                android:layout_height="wrap_content"
                android:layout_width="0dip"
                android:layout_weight="0.3"
                android:text="Age" />

        </LinearLayout>

        <ListView
            android:id="+@id/MyDataListView"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"/>

     </LinearLayout>

然后，您需要一个自定义适配器，该适配器使用POJO中的值设置列表视图中的字段.互联网上有很多关于此的教程.

You then need a custom adapter which sets the fields in the list view with the values from your POJO. There are plenty of tutorials on the internet for this.
