okhttp post提交参数完成登录功能 保存返回的token

作为一名android开发者，通过博客记录自己成长的道路，以下是小白在开发实践中的登录功能实现的一些步骤及功能，希望对做这一部分功能的伙伴有一定的帮助

1.登录的界面布局

2.登录的url、sp保存token、okhttp post请求

3.登录的ui界面，功能代码....

登录界面如下，勿喷

附上sp工具代码

PreferenceUtils.java

package fho.nak.jeekup.nakfho.utils;

import android.content.Context;
import android.content.SharedPreferences;

/**
 * sp工具类
 */
public class PreferenceUtils {

   public static void putString(Context context, String key, String value){
      SharedPreferences sp = context.getSharedPreferences("config", Context.MODE_PRIVATE);
      sp.edit().putString(key, value).commit();
   }

   public static String getString(Context context, String key, String defValue){
      SharedPreferences sp = context.getSharedPreferences("config", Context.MODE_PRIVATE);
      return sp.getString(key, defValue);
   }
   public static String getString(Context context, String key){
      SharedPreferences sp = context.getSharedPreferences("config", Context.MODE_PRIVATE);
      return getString(context,key,"");
   }

   public static void putBoolean(Context context, String key, boolean value){
      SharedPreferences sp = context.getSharedPreferences("config", Context.MODE_PRIVATE);
      sp.edit().putBoolean(key, value).commit();
   }

   public static boolean getBoolean(Context context, String key, boolean defValue){
      SharedPreferences sp = context.getSharedPreferences("config", Context.MODE_PRIVATE);
      return sp.getBoolean(key, defValue);
   }

   public static boolean getBoolean(Context context, String key){
      SharedPreferences sp = context.getSharedPreferences("config", Context.MODE_PRIVATE);
      return getBoolean(context,key,false);
   }

   public static void putInt(Context context, String key, int value){
      SharedPreferences sp = context.getSharedPreferences("config", Context.MODE_PRIVATE);
      sp.edit().putInt(key, value).commit();
   }

   public static int getInt(Context context, String key, int defValue){
      SharedPreferences sp = context.getSharedPreferences("config", Context.MODE_PRIVATE);
      return sp.getInt(key, defValue);
   }

   public static int getInt(Context context, String key){
      SharedPreferences sp = context.getSharedPreferences("config", Context.MODE_PRIVATE);
      return getInt(context,key,-1);
   }
 
}

以上简单的登录功能就完成了，希望对大家有帮助，也希望大家能够多多交流，一起成长
