嘿家伙我在listview(自定义适配器)面临问题 . 我已经实现了播放音频(mp3文件)的媒体播放器的listview . 我已经在我的原始文件夹中包含了mp3文件 . 我知道这是一个循环视图 . 我的问题是在6-7行之后，相同的mp3文件与第0个位置的文件相同 . 任何解决方案？我的主要活动公共类MainActivity扩展了Activity实现OnItemClickListener {

ListView lview3;

ListViewCustomAdapter adapter;

private ArrayList itemList;

private ItemBean bean;

@Override

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.main);

prepareArrayLits();

lview3 = (ListView) findViewById(R.id.listView1);

adapter = new ListViewCustomAdapter(this, itemList);

lview3.setAdapter(adapter);

lview3.setOnItemClickListener(this);

}

@Override

public void onItemClick(AdapterView> arg0, View arg1, int position1, long id) {

// TODO Auto-generated method stub

ItemBean bean = (ItemBean) adapter.getItem(position1);

Toast.makeText(this, "Title => "+bean.getTitle()+" \n Description => "+bean.getDescription(), Toast.LENGTH_SHORT).show();

}

/* Method used to prepare the ArrayList,

* Same way, you can also do looping and adding object into the ArrayList.

*/

public void prepareArrayLits()

{

itemList = new ArrayList();

AddObjectToList(R.drawable.ic_add, "Add", "Add desc",R.raw.mp1);

AddObjectToList(R.drawable.ic_delete, "Delete", "Delete desc",R.raw.mp2);

AddObjectToList(R.drawable.ic_down, "Down", "Down desc",R.raw.mp3);

AddObjectToList(R.drawable.ic_info, "Information", "Information desc",R.raw.mp4);

AddObjectToList(R.drawable.ic_help, "Help", "Help desc",R.raw.mp5);

AddObjectToList(R.drawable.ic_download, "Download", "Download desc",R.raw.mp6);

AddObjectToList(R.drawable.ic_mail, "Mail", "Mail desc",R.raw.mp7);

AddObjectToList(R.drawable.ic_search, "Search", "Search desc",R.raw.mp8);

AddObjectToList(R.drawable.ic_settings, "Settings", "Settings desc",R.raw.mp9);

}

// Add one item into the Array List

public void AddObjectToList(int image, String title, String desc,int audio)

{

bean = new ItemBean();

bean.setDescription(desc);

bean.setImage(image);

bean.setTitle(title);

bean.setAudio(audio);

itemList.add(bean);

}
