Android 使用SharedPreferences資料存放區

標籤：資料存放區   android   sharedpreferences   sputil   

自己寫了個SP輔助類

雖然寫的有點囉嗦，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輔助類 * @author YQY * * */@SuppressLint("CommitPrefEdits")public class SPUtil {private static SharedPreferences mSP;private static String spName = "yqy_testsputil";/** * put * @param context 環境 * @param name 鍵 * @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);}}
