Android UI设计--ListView Item的OnItemLongClickListener同时监听两种事件

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;



	@Override

	protected 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()

		{



			@Override

			public 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()

		{



			@Override

			public 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);

		}

		@Override

		public int getCount() {

			return musicList.size();

		}



		@Override

		public Object getItem(int position) {

			return musicList.get(position);

		}



		@Override

		public long getItemId(int position) {

			return position;

		}



		@Override

		public 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）
