本论坛将全面搬家到：http://www.cnblogs.com/91program，请大家以后来这里看看。

ListView 点击响应代码(如下)，以前都是正确的：

private class MusicListItemClickListener implements OnItemClickListener {@Overridepublic void onItemClick(AdapterView<?> parent, View view, int position,long id) {}}

可参阅以前的一博文：http://blog.csdn.net/91program/article/details/39232721

在新的工程使用时，先提示 onItemClick 需要删除 @Override。我直接将 onItemClick 删除，再自动增加函数时，发现自动增加的函数变成如下所示的，参数的参数发生了变化，特别是第一个参数，由 AdapterView 变成 AdapterViewCompat。代码不再提示错误，运行之！

private class contactsListItemClickListener implements OnItemClickListener {// AdapterViewCompat.OnItemClickListener@Overridepublic void onItemClick(AdapterViewCompat<?> arg0, View arg1, int arg2,long arg3) {// TODO Auto-generated method stubint position = arg2;int id = (int) arg3;Log.i(phoneBookInfo.TAG, "position: " + Integer.toString(position) + " id: " + Integer.toString(id));}}

运行时出现错误。提示如下：

对比之前的代码，与现在的代码，发现可能是 AdapterViewCompat 引起的。所以强制将 OnItemClickListener 声明为 AdapterView 的成员，如下：

private class contactsListItemClickListener implements AdapterView.OnItemClickListener {@Overridepublic void onItemClick(AdapterView<?> parent, View view, int position,long id) {// TODO Auto-generated method stubLog.i(phoneBookInfo.TAG, "position: " + Integer.toString(position) + " id: " + Long.toString(id));}}

这样自动增加的 onItemClick 函数终于和以前一样了。
运行之，正确！
