首先要继承OnItemLongClickListener

public class Set_Music extends ListActivity implements OnItemLongClickListener{

然后设置权限：

getListView().setOnItemLongClickListener(this);

重写方法

public boolean onItemLongClick(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {

String str = list.get(arg2).get("name");

删掉长按的item
list.remove(arg2);

动态更新listview
adapter.notifyDataSetChanged();
