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

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) {

推荐答案

阅读文档.您不是第一个愿意发现...的人.

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
