SharedPreferences改造，写个工具类

安卓开发中，常使用SharedPreferences保存数据，不过感觉有点麻烦，自己动手改造下吧，数据存取只需要参数上下文和key与value，简单方便，码农必备啊，哈哈哈…下面贴代码喽…
package utils;

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

public class SharedPreferencesUtils {

public static final String SP_NAME = "config";public static void saveBoolean(Context context,String key , boolean value){    SharedPreferences sp = context.getSharedPreferences(SP_NAME, 0);    sp.edit().putBoolean(key, value).commit();}public static boolean getBoolean(Context context,String key,boolean defValue){    SharedPreferences sp = context.getSharedPreferences(SP_NAME, 0);    return sp.getBoolean(key, defValue);}public static void saveString(Context context,String key , String value){    SharedPreferences sp = context.getSharedPreferences(SP_NAME, context.MODE_PRIVATE);    sp.edit().putString(key, value).commit();}public static String getString(Context context,String key,String defValue){    SharedPreferences sp = context.getSharedPreferences(SP_NAME, context.MODE_PRIVATE);    return sp.getString(key, defValue);}public static void saveLong(Context context,String key , long value){    SharedPreferences sp = context.getSharedPreferences(SP_NAME, 0);    sp.edit().putLong(key, value).commit();}public static long getLong(Context context,String key,long defValue){    SharedPreferences sp = context.getSharedPreferences(SP_NAME, 0);    return sp.getLong(key, defValue);}public static void saveInt(Context context,String key , int value){    SharedPreferences sp = context.getSharedPreferences(SP_NAME, context.MODE_PRIVATE);    sp.edit().putInt(key, value).commit();}public static int getInt(Context context,String key,int defValue){    SharedPreferences sp = context.getSharedPreferences(SP_NAME, context.MODE_PRIVATE);    return sp.getInt(key, defValue);}public static void saveFloat(Context context,String key , float value){    SharedPreferences sp = context.getSharedPreferences(SP_NAME, context.MODE_PRIVATE);    sp.edit().putFloat(key, value).commit();}public static float getFloat(Context context,String key,float defValue){    SharedPreferences sp = context.getSharedPreferences(SP_NAME, context.MODE_PRIVATE);    return sp.getFloat(key, defValue);}

}
