“方法setListAdapter（ArrayAdapter）未定义类型create” [英] "The method setListAdapter(ArrayAdapter) is undefined for the type create"

问题描述

我是全新的java& android，所以我试图找到有用的样本从android&数据库。我发现这个博客有一个项目：

http://saigeethamn.blogspot.com/2009/10/android-developer-tutorial-part-12.html

我运行的项目，它的工作正常，但我试图创建一个新的项目复制&粘贴代码，这不工作:(

我在这一行有一个问题：

  this.setListAdapter（new ArrayAdapter< String>（this，android.R.layout.simple_list_item_1，results））; 
  

这是我得到的错误：

setListAdapter（ArrayAdapter）方法未定义类型create

它看起来像一个C＃中的方法，但我可以在原始项目中找到它。

解决方案

当你调用 this.setListAdapter 这必须扩展 ListActivity 可能你的类只是扩展 Activity 。

I am completely new to java & android, so I tried to find useful samples from android & databases. I found this blog with a project:

http://saigeethamn.blogspot.com/2009/10/android-developer-tutorial-part-12.html

I ran the project and it works fine, but I was trying to create a new project to copy & paste the code in it and this is not working :(

I had a problem on this line:

this.setListAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1,results));

This is the error I get:

The method setListAdapter(ArrayAdapter) is undefined for the type create

It looks like a method in C#, but I can find it in the original project.

Where did I make a mistake?

解决方案

When you call this.setListAdapter this must extend ListActivity probably you class just extends Activity.
