Android中播发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(){			@Override			public void onClick(View v) {				// TODO Auto-generated method stub								Intent 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{	@Override	public IBinder onBind(Intent intent) {		// TODO Auto-generated method stub		return null;	}	@Override	public int onStartCommand(Intent intent, int flags, int startId) {		// TODO Auto-generated method stub				MediaPlayer 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 android:name="cn.design.service.PlayService">

</service>
