Android：onListItemClick in Activity [英] Android: onListItemClick in Activity

问题描述

上一次我在这里问了一个问题，所以我想这是值得一试，再试一次。

我正在使用Fedor的懒惰列表此链接：
懒惰在ListView中加载图像

它的工作方式就像一个魅力。但是，Fedor正在使他的主要类别扩展到 Activity 而不是 ListActivity 。因此，我不再能够使用listItemClick监听器。 Eclipse在 onListItemClick（）之间声明一些错误。当我转到

  @Override 
 protected void onListItemClick（ListView l，View v，int position，long id ）{
 super.onListItemClick（l，v，position，id）; 
 // Intent launcher here 
} 
  

into

  protected void onListItemClick（ListView l，View v，int position，long id）{
 // Intent launcher here 
} 
  

但意图启动器不起作用。

当我在 ListActivity 中打开活动 code>，Eclipse不会错开，但是我的模拟器给我一个关闭的力量。

如何获取



• $ {code> onListItemClick（）点击活动（最好）


• 或者我将代码转换为 ListActivity 而不用强制关闭？

非常感谢

解决方案

我正在写我的答案：

1）@Falmarri的代码需要一些更新

2）我建议的修改完全被拒绝XD

3）Stackoverflow不允许我写评论

这是代码：

  ListView listView =（ListView）findViewById（R.id.my_listview_in_layout）; 
 listview.setOnItemClickListener（new AdapterView.OnItemClickListener（）{
 @Override 
 public void onItemClick（AdapterView<？> parent，View view，int position，long id）{
 //做东西
 // ... 
} 
}）; 
  

参考：根据 android.widget.AdapterView.OnItemClickListener ，公共方法onItemClick（）是点击项目时调用方法{而不是未知的保护方法onListItemClick（）}

Previous time I asked a question here I learned a lot so I guess it's worth a shot to try it again.

I am using the lazy list by Fedor from this link: Lazy load of images in ListView

It's working like a charm. BUT, Fedor is making his main class extend Activity instead of ListActivity. Because of this, I am no longer able to use a listItemClick listener. Eclipse declares some errors around onListItemClick(). It works when I turn

    @Override
protected void onListItemClick(ListView l, View v, int position, long id) {
    super.onListItemClick(l, v, position, id);
     // Intent launcher here
}

into

   protected void onListItemClick(ListView l, View v, int position, long id) {
     // Intent launcher here
   }

But the intent launcher doesn't work. Neither does a toast notification.

When I turn the Activity in a ListActivity, Eclipse doesn't stagger, but my emulator gives me a force close.

How do I get

• Either onListItemClick() click in the activity (preferable)
• Or do I transform the code into a ListActivity without force close?

Thanks a lot in advance.

解决方案

I am writing my answer as:

1) the code by @Falmarri needs some update
2) My suggested edit was totally rejected XD
3) Stackoverflow is not allowing me to write a comment.

Here is the code:

ListView listView = (ListView) findViewById(R.id.my_listview_in_layout);
listview.setOnItemClickListener(new AdapterView.OnItemClickListener(){
    @Override
    public void onItemClick(AdapterView<?> parent, View view, int position, long id){
        //Do stuff
        //...
    }
});

Reference: According to android.widget.AdapterView.OnItemClickListener , public method onItemClick() is the method invoked when an item is clicked {instead of unknown protected method onListItemClick() }
