ListView 點(diǎn)擊響應(yīng)代碼(如下)，以前都是正確的：

private?class?MusicListItemClickListener?implements?OnItemClickListener?{


	@Override
	public?void?onItemClick(AdapterView?parent,?View?view,?int?position,long?id)?{
	}
}

在新的工程使用時(shí)，先提示 onItemClick 需要?jiǎng)h除 @Override。我直接將 onItemClick 刪除，再自動(dòng)增加函數(shù)時(shí)，發(fā)現(xiàn)自動(dòng)增加的函數(shù)變成如下所示的，參數(shù)的參數(shù)發(fā)生了變化，特別是第一個(gè)參數(shù)，由 AdapterView 變成 AdapterViewCompat。代碼不再提示錯(cuò)誤，運(yùn)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));
	}
}

運(yùn)行時(shí)出現(xiàn)錯(cuò)誤。提示如下：

對(duì)比之前的代碼，與現(xiàn)在的代碼，發(fā)現(xiàn)可能是 AdapterViewCompat 引起的。所以強(qiáng)制將 OnItemClickListener 聲明為 AdapterView 的成員，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));
	}
}

這樣自動(dòng)增加的 onItemClick 函數(shù)終于和以前一樣了。
運(yùn)行之，正確！
