判断网络连接是否正常EventerBus发送

依赖:

compile 'org.greenrobot:eventbus:3.0.0'

public class NetBroadCastReciver{
public int getNetype(Context context) {
int netType = -1;
ConnectivityManager connMgr = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);

NetworkInfo networkInfo = connMgr.getActiveNetworkInfo();

//无网络
if (networkInfo == null) {
return netType;
}
int nType = networkInfo.getType();
//手机网络
if (nType == ConnectivityManager.TYPE_MOBILE) {
netType = 2;
} else if (nType == ConnectivityManager.TYPE_WIFI) {//wifi网络
netType = 1;
}
//返回
return netType;
}
}

主线程的具体操作

EventBus.getDefault().register(this);//注册EventBus

//网络连接判断
int netype =new NetBroadCastReciver().getNetype(getActivity());

 if(netype==1||netype==2){
EventBus.getDefault().post("成功");
}else if(netype==-1){
EventBus.getDefault().post("失败");
}

//接受
@Subscribe
public void onEventMainThread(Object event) {
Toast.makeText(getActivity(),event+"",Toast.LENGTH_SHORT).show();
}
//反注册

@Override
public void onDestroy() {
super.onDestroy();
EventBus.getDefault().unregister(this);
}
