我有一个的ListView 与一个 BaseAdapter 导出自己的自定义适配器。在的ListView 每个项目都有，例如 ImageView的子项和的TextView 。

我怎么能知道用户点击这些子项中的哪一个？是否有可能附着在 getView 功能的监听器，例如，或者可以说是一个问题？

编辑：目前，我有一个 onItemClick ，其中包含的ListView 的活动。有没有知道哪些子项在ListView中的特定项目已经被通过检查PARAMS pssed $ P $什么好办法 onItemClick 。

  @覆盖
公共无效onItemClick（适配器视图＆LT;＆gt;一种，视图V，INT POS，长I​​D）{
。
。
}
 

解决方案

您可以做到这一点。您需要修改你的getView方法：

  @覆盖
公共查看getView（最终诠释的立场，观点行，最终的ViewGroup父）{
    ...
    YourWrapper包装= NULL;
    如果（行== NULL）{
        行= getLayoutInflater（）膨胀（R.layout.your_row，父母，假）。
        包装=新YourWrapper（行）;
        row.setTag（包装）;
    } 其他 {
        包装=（YourWrapper）row.getTag（）;
    }

    wrapper.yourSubView.setOnClickListener（新View.OnClickListener（）
    {
    @覆盖
    公共无效的onClick（视图v）{
        // 做一点事
    }
    ...
}
 

I'm having a ListView with my own custom adapter derived from a BaseAdapter. Each item in the ListView has sub items such as ImageView and TextView.

How can I know which one of these sub items the user clicked? Is it possible to attach a listener in the getView function for example, or could that be a problem?

/ Henrik

Edit: Currently I have a onItemClick in the Activity which contains the ListView. Is there any good way to know which sub item in a specific item in the ListView which has been pressed by checking the params in the onItemClick.

@Override 
public void onItemClick(AdapterView<?> a, View v, int pos, long id) {
.
.
}

You can do it. You need to modify your getView method:

@Override
public View getView(final int position, View row, final ViewGroup parent) {
    ...     
    YourWrapper wrapper = null;
    if (row == null) {
        row = getLayoutInflater().inflate(R.layout.your_row, parent, false);
        wrapper = new YourWrapper(row);
        row.setTag(wrapper);
    } else {
        wrapper = (YourWrapper) row.getTag();
    }

    wrapper.yourSubView.setOnClickListener(new View.OnClickListener()   
    {               
    @Override
    public void onClick(View v) {
        // do something
    }
    ...
}
