如何在Andoid ListView中获取选定的项目索引?

问题描述：

大家好:)

我有一个列表视图，我想获取选定的项目索引以对其进行一些处理

如何获得此索引为整数值?

这是我的代码:

Hi all :)

I have a listview, and I want to get the selected item index to do some process on it

how can I get this index as an integer value ?

this is my code:

final ListView list = (ListView)findViewById(android.R.id.list);
		list.setClickable(true);
		list.setOnItemClickListener(new AdapterView.OnItemClickListener() {

		public void onItemClick(AdapterView<?> arg0, View arg1, int position, long arg3) {
	    
		  }
		});

谢谢:)

thanks all :)

阅读文档.您不是第一个愿意发现...的人.

有关使用ListView的教程:

Read the documentation. You are not the first person ever willing to find out...

Tutorial on using ListView:
http://developer.android.com/resources/tutorials/views/hello-listview.html[^]

public void onItemClick(AdapterView<?> arg0, View arg1, int position, long arg3) {	    
		  }

int位置将为您提供int中的选定项目索引.

The int position will give you the selected item index in int.

我的用户如下所示，工作正常

i user like below and working nice

mylistview.setOnItemClickListener(new OnItemClickListener() {
			@Override
			public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
					long arg3) {
				MyObject selection = (MyObject) arg0.getItemAtPosition(arg2);
				
			}
		});

不同的是
我没有使用

the different is
i havent use

list.setClickable(true);

并放置

@Override

属性
