android: 長按刪除listview的item

首先要繼承OnItemLongClickListener

public class Set_Music extends ListActivity implements OnItemLongClickListener{

然後設置權限：

getListView().setOnItemLongClickListener(this);

重寫方法

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

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

刪掉長按的item
list.remove(arg2);

動態更新listview
adapter.notifyDataSetChanged();
