适用于listview的自定义布局的适配器

Question

I am developing an android project in which I have to load from group of String arrays(say title,description,id) to the listview item TextView.

I did something similar with a database using a cursor like this

String[] from = new String[]{"medicine","healthsystem"};
            int[] to = new int[] {R.id.textlist1,R.id.textlist2};
             // Now creating an array adapter and set it to display using my row
            SimpleCursorAdapter notes =new SimpleCursorAdapter(this,R.layout.notes_row, c, from, to);

I listed all the targets in "from" and all the origin in "to". Now my problem is I don't have a database so cant use a cursor.

I have 3 arrays of strings which i want to load into textviews(title,description,id) of each item

How to do this Please kindly help me out thank you :)

Answer 1

If you don't have a cursor, why are you using a SimpleCursorAdapter?

Read this article about creating a SimpleListView using SimpleAdapter for alternate ideas.

Answer 2

在Android SDK附带的ApiDemos项目中有很多来自各种数据源的填充列表的示例 - 浏览这些，你应该找到一个适合你想要做的事情。

First of all you need to create a Class that holds that information, something like:

public class StringHolder{
    String titte;
    String description;
    int id;
}

Then you create the layout of your row that says where you want your title, your description and your image.

Then you create an Adapter. The adapter will hold your data and will say for each position in the list what information should be loaded.

At last you need to use your adapter in an activity.
