本文主要是介绍Android 使用SharedPreferences数据存储，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
自己写了个SP辅助类
虽然写的有点啰嗦，也是自己的成果。如下：
package com.yqy.yqy_testsputil;import android.annotation.SuppressLint;
import android.app.Activity;
import android.content.Context;
import android.content.SharedPreferences;
/*** SP辅助类* @author YQY***/
@SuppressLint("CommitPrefEdits")
public class SPUtil {private static SharedPreferences mSP;private static String spName = "yqy_testsputil";/*** put* @param context 环境* @param name 键* @param object 值*/public static void put(Context context,String name,Object object){mSP = context.getSharedPreferences(spName, Activity.MODE_PRIVATE);SharedPreferences.Editor editor = mSP.edit();if(object instanceof String){editor.putString(name,(String) object);}else if(object instanceof Integer){editor.putInt(name, (Integer) object);}else if(object instanceof Long){editor.putLong(name, (Long) object);}else if(object instanceof Float){editor.putFloat(name, (Float) object);}else if(object instanceof Boolean){editor.putBoolean(name, (Boolean) object);}editor.commit();}public static void set(Context context, String what, String value) {SharedPreferences sharedPreferences = context.getSharedPreferences(spName, 0);sharedPreferences.edit().putString(what, value).commit();}public static String getString(Context context,String name){mSP = context.getSharedPreferences(spName, Activity.MODE_PRIVATE);return mSP.getString(name, "");}public static int getInt(Context context,String name){mSP = context.getSharedPreferences(spName, Activity.MODE_PRIVATE);return mSP.getInt(name, 0);}public static Long getLong(Context context,String name){mSP = context.getSharedPreferences(spName, Activity.MODE_PRIVATE);return mSP.getLong(name, 0);}public static Float getFloat(Context context,String name){mSP = context.getSharedPreferences(spName, Activity.MODE_PRIVATE);return mSP.getFloat(name, 0);}public static boolean getboolean(Context context,String name){mSP = context.getSharedPreferences(spName, Activity.MODE_PRIVATE);return mSP.getBoolean(name, false);}}
这篇关于Android 使用SharedPreferences数据存储的文章就介绍到这儿，希望我们推荐的文章对编程师们有所帮助！
