android绑定服务核心代码

Intent serviceIntent= new Intent(MainActivity.this, KlineService.class);
MainActivity.this.bindService(serviceIntent, serviceConnection, BIND_AUTO_CREATE);

private ServiceConnection serviceConnection = new ServiceConnection() {
@Override
public void onServiceConnected(ComponentName componentName, IBinder iBinder) {
KlineService.MyBinder binder = (KlineService.MyBinder) iBinder; //通过IBinder获取Service
klineService= binder.getService();
}
public void onServiceDisconnected(ComponentName componentName) {

}
};

在OnDestory方法里面取消绑定服务

MainActivity.this.unbindService(serviceConnection);
Intent intent = new Intent(MainActivity.this, KlineService.class);
MainActivity.this.stopService(intent);

2 KLineService

private String tag="KlineService";
private final IBinder binder = new MyBinder();
public class MyBinder extends Binder {
public KlineService getService() {
return KlineService.this;
}
}
