Android应用开发--MP3音乐播放器代码实现（一），android基础入门

• @param mp3Infos

*/

public void setListAdpter(List mp3Infos) {

List mp3list = new ArrayList();

findex.php/tags-1038.html" >or (Iterator iterator = mp3Infos.iterator(); iterator.hasNext() {

Mp3Info mp3Info = (Mp3Info) iterator.next();

HashMap map = new HashMap();

map.put(“title”, mp3Info.getTitle());

map.put(“Artist”, mp3Info.getArtist());

map.put(“duration”, String.valueOf(mp3Info.getDuration()));

map.put(“size”, String.valueOf(mp3Info.getSize()));

map.put(“url”, mp3Info.getUrl());

mp3list.add(map);

}

mAdapter = new SimpleAdapter(this, mp3list,

R.layout.music_list_item_layout, new String[] { “title”, “Artist”, “duration” },

new int[] { R.id.music_title, R.id.music_Artist, R.id.music_duration });

mMusiclist.setAdapter(mAdapter);

}

实现效果如图：

需求2：点击列表的每一项，启动一个服务来播放音乐

1.   注册条目点击监听器OnItemClickListener

2.   定义一个实现OnItemClickListener接口的内部类

3.   定义一个继承Service的服务类PlayerSer
