Android中播放mp3文件

在Service中播放，可以在后台进行播放

package cn.edu.design;import android.app.Activity;import android.content.Intent;import android.os.Bundle;import android.view.View;import android.view.View.OnClickListener;import android.widget.Button;import cn.design.service.PlayService;public class BroadCastActivity extends Activity {private Button button=null;/** Called when the activity is first created. */    @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.main);                button=(Button)findViewById(R.id.play);        button.setOnClickListener(new OnClickListener(){@Overridepublic void onClick(View v) {// TODO Auto-generated method stubIntent intent=new Intent();intent.setClass(BroadCastActivity.this, PlayService.class);startService(intent);}                });            }}

继承Service，播放Mp3文件

package cn.design.service;import android.app.Service;import android.content.Intent;import android.media.MediaPlayer;import android.net.Uri;import android.os.Environment;import android.os.IBinder;public class PlayService extends Service{@Overridepublic IBinder onBind(Intent intent) {// TODO Auto-generated method stubreturn null;}@Overridepublic int onStartCommand(Intent intent, int flags, int startId) {// TODO Auto-generated method stubMediaPlayer medPlay=MediaPlayer.create(this,Uri.parse("/sdcard/music/6.mp3"));medPlay.start();return super.onStartCommand(intent, flags, startId);}}

在AndroidManifest.xml中添加如下信息

</service>
