Android 之 ListView 点击响应代码?

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 {


	@Override
	public 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
	@Override
	public void onItemClick(AdapterViewCompat<?> arg0, View arg1, int arg2,
			long arg3) {
		// TODO Auto-generated method stub
		int 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 {
	@Override
	public void onItemClick(AdapterView<?> parent, View view, int position,
			long id) {
		// TODO Auto-generated method stub
		Log.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!
