该怎么用SharedPreferences来存储控件的值

[wldzh]

SharedPreferences用来读写控件的值，能修改和删除，有没有谁有完整的例子啊，

/** * 设置密码 * * @param password */ public static void setPassWord(Context mContext,String userName,String password) { SharedPreferences settings = mContext.getSharedPreferences( mContext.getPackageName(), 0); Editor editor = settings.edit(); password = AesUtil.encrypt(password, mContext); editor.putString(userName, password); //Log.i("ecmt", "password:"+password+" userName:"+userName+" save:"+mContext.getPackageName()); editor.commit(); } /** * 取得密码 * * @return */ public static String getPassword(Context mContext,String userName) { SharedPreferences settings = mContext.getSharedPreferences( mContext.getPackageName(), 0); String password = settings.getString(userName, ""); if(password.length() == 0) return ""; password = AesUtil.decrypt(password, mContext); //Log.i("ecmt", "password:"+password+" userName:"+userName+" read:"+mContext.getPackageName()); return password; } /** * 清除密码 * @param mContext * @param userName */ public static void removePassword(Context mContext,String userName){ SharedPreferences settings = mContext.getSharedPreferences( mContext.getPackageName(), 0); Editor editor = settings.edit(); editor.remove(userName); editor.commit(); }
