代碼如下：
public class MainActivity extends AppCompatActivity {
musicservice ms;
boolean mb = false;
private Button play;
private Button stop;
private ProgressBar progressBar;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
play=(Button)findViewById(R.id.play);
stop=(Button)findViewById(R.id.stop);
progressBar=(ProgressBar) findViewById(R.id.progressBar3);
if(ms!=null) {
progressBar.setMax(ms.getdur());
}
play.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
ms.play();
}
});
stop.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
ms.stop();
}
});
}
Handler handler=new Handler();
public void handleMessage(Message msg){
if(ms!=null) {
progressBar.setProgress(msg.what);
}
}
Runnable runnable = new Runnable() {
@Override
public void run() {
while(true){
if(ms!=null) {
Message msg = new Message();
msg.what = ms.getcurtime();
handler.sendMessage(msg);
}
try {
Thread.sleep(1000);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
};
ServiceConnection mc = new ServiceConnection() {
@Override
public void onServiceConnected(ComponentName name, IBinder service) {
musicservice.LocalBinder binder = (musicservice.LocalBinder)service;
ms=binder.getservice();
mb=true;
}
@Override
public void onServiceDisconnected(ComponentName name) {
mb=false;
}
};
protected void onStart(){
super.onStart();
Intent mIntent = new Intent(this, musicservice.class);
bindService(mIntent, mc, BIND_AUTO_CREATE);
};
}
service
public class musicservice extends Service {
MediaPlayer mp;
private final IBinder iBinder = new LocalBinder();
public musicservice() {
}
public class LocalBinder extends Binder{
musicservice getservice()
{

}
}
@Override
public void onCreate() {
super.onCreate();
mp=MediaPlayer.create(this,R.raw.emin);
}
@Override

return iBinder;
}
public int getcurtime(){
