对SharePreference的封装

今天需要用到SharePreference来保存一些设置参数,因为要用到很多次 所以对它进行了封装:

public class PrefUtils { public static void putBoolean(String key, boolean value, Context ctx) { SharedPreferences sp = ctx.getSharedPreferences("config", Context.MODE_PRIVATE); sp.edit().putBoolean(key, value).commit(); } public static boolean getBoolean(String key, boolean defValue, Context ctx) { SharedPreferences sp = ctx.getSharedPreferences("config", Context.MODE_PRIVATE); return sp.getBoolean(key, defValue); } public static void putString(String key, String value, Context ctx) { SharedPreferences sp = ctx.getSharedPreferences("config", Context.MODE_PRIVATE); sp.edit().putString(key, value).commit(); } public static String getString(String key, String defValue, Context ctx) { SharedPreferences sp = ctx.getSharedPreferences("config", Context.MODE_PRIVATE); return sp.getString(key, defValue); } public static void putInt(String key, int value, Context ctx) { SharedPreferences sp = ctx.getSharedPreferences("config", Context.MODE_PRIVATE); sp.edit().putInt(key, value).commit(); } public static int getInt(String key, int defValue, Context ctx) { SharedPreferences sp = ctx.getSharedPreferences("config", Context.MODE_PRIVATE); return sp.getInt(key, defValue); } public static void remove(String key, Context ctx) { SharedPreferences sp = ctx.getSharedPreferences("config", Context.MODE_PRIVATE); sp.edit().remove(key).commit(); } }
