存放网络设置方法的类

package com.example.day_01_post;

import android.content.Context;
import android.net.ConnectivityManager;
import android.net.NetworkInfo;

public class Urldata {
    //判断是否有网络
    public  static  boolean geturl(Context context){
        ConnectivityManager connectivityManager = (ConnectivityManager) context.getSystemService(context.CONNECTIVITY_SERVICE);
        NetworkInfo activeNetworkInfo = connectivityManager.getActiveNetworkInfo();
        return activeNetworkInfo!=null&&activeNetworkInfo.isAvailable();

    }
    //判断网络类型(ConnectivityManager.TYPE_MOBILE;移动数据)
    public static  boolean gettype(Context context){
        ConnectivityManager connectivityManager= (ConnectivityManager) context.getSystemService(context.CONNECTIVITY_SERVICE);
        NetworkInfo activeNetworkInfo = connectivityManager.getActiveNetworkInfo();
        return activeNetworkInfo.getType()==ConnectivityManager.TYPE_MOBILE;
    }
}
