例如mp3播放器的音乐播放列表，点击一个item后开始播放音乐(OnItemClickListener)，长按让其进入编辑模式（不跳转到另一个页面，还在同一个页面），此时用到了OnItemLongClickListener，然后再次长按某一个音乐的条目进行拖动（改变列表顺序），这时需要屏蔽掉上一次长按进入编辑模式的事件。实现代码如下
package com.example.longdoubleclickdemo;import java.util.ArrayList;import java.util.List;import android.app.Activity;import android.content.Context;import android.os.Bundle;import android.view.LayoutInflater;import android.view.View;import android.view.ViewGroup;import android.widget.AdapterView;import android.widget.BaseAdapter;import android.widget.ImageView;import android.widget.ListView;import android.widget.TextView;import android.widget.Toast;public class MainActivity extends Activity {private ListView mMusicListView;private List<MusicItem> musicList;private MyAdapter mAdapter;private TextView mTitleName;private boolean mEditMode;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);mTitleName = (TextView)findViewById(R.id.titlebar);mMusicListView = (ListView)findViewById(R.id.music_list);initData();mAdapter = new MyAdapter(this);mMusicListView.setAdapter(mAdapter);initListeners();}private void initData(){musicList = new ArrayList<MusicItem>();for(int i = 0; i < 20; i++){musicList.add(setMusicItem(i));}}public boolean getEditMode(){return mEditMode;}public void setEditMode(boolean mEditMode){this.mEditMode = mEditMode;}private void initListeners(){mMusicListView.setOnItemClickListener(new ListView.OnItemClickListener(){@Overridepublic void onItemClick(AdapterView<?> parent, View view, int position,long id) {//Toast.makeText(getApplicationContext(), "默认模式", Toast.LENGTH_SHORT).show();}});mMusicListView.setOnItemLongClickListener(new ListView.OnItemLongClickListener(){@Overridepublic boolean onItemLongClick(AdapterView<?> parent, View view,int position, long id) {boolean mEditMode = getEditMode();if(!mEditMode){setEditMode(true);Toast.makeText(getApplicationContext(), "进入编辑模式", Toast.LENGTH_SHORT).show();mTitleName.setText("编辑模式");}else{Toast.makeText(getApplicationContext(), "编辑 "+position, Toast.LENGTH_SHORT).show();}return false;}});}public MusicItem setMusicItem(int position){MusicItem musicItem = new MusicItem();musicItem.setMusicTitle("music "+position);musicItem.setMusicDragIcon(getResources().getDrawable(R.drawable.change_order_grip));return musicItem;}static class ViewHolder{public TextView musicName;public ImageView musicDragIcon;}class MyAdapter extends BaseAdapter{private LayoutInflater mInflater = null;public MyAdapter(Context context){this.mInflater = LayoutInflater.from(context);}@Overridepublic int getCount() {return musicList.size();}@Overridepublic Object getItem(int position) {return musicList.get(position);}@Overridepublic long getItemId(int position) {return position;}@Overridepublic View getView(int position, View convertView, ViewGroup parent) {ViewHolder holder = null;if(null == convertView){holder = new ViewHolder();convertView = mInflater.inflate(R.layout.music_list_item, null);holder.musicName = (TextView)convertView.findViewById(R.id.music_name);holder.musicDragIcon = (ImageView)convertView.findViewById(R.id.music_drag);convertView.setTag(holder);}else{holder = (ViewHolder)convertView.getTag();}holder.musicName.setText(musicList.get(position).getMusicTitle());holder.musicDragIcon.setImageDrawable(musicList.get(position).getMusicDragIcon());return convertView;}}}
运行结果：第一次长按触发进入编辑模式，例如导航栏目的改变，第二次或以后再长按触发item则执行其他的item时间，例如拖拽更改列表顺序（以后更新）
