Android 带ListView的音乐播放器

核心提示：IllegalStateException, IOException{Uri uri = Uri.withAppendedPath(MediaStore.Audio.Media.EXTERNAL_CONTENT_URI,String.valueOf(arg3));TextView tv = (TextView) fin

IllegalStateException, IOException{

Uri uri = Uri.withAppendedPath(

MediaStore.Audio.Media.EXTERNAL_CONTENT_URI,

String.valueOf(arg3));

TextView tv = (TextView) findViewById(R.id.name);

tv.setText(uri.toString());

mp.release();

mp = MediaPlayer.create(this, uri);

mp.start();

}

list.setOnItemClickListener(new OnItemClickListener(){

@Override

public void onItemClick(AdapterView arg0, View arg1, int arg2,

long arg3) {

// TODO Auto-generated method stub

try {

playMusic(arg3);

} catch (IllegalArgumentException e) {

// TODO Auto-generated catch block

e.printStackTrace();

} catch (IllegalStateException e) {

// TODO Auto-generated catch block

e.printStackTrace();

} catch (IOException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

}

});

因为这是个音乐播放器 界面也没什么特别之处 就此略过 只有一个关于所有音乐文件的ListView

done!
