+实验五
+=
+一、实验目的
+-
+掌握在Android App中存储数据
+
+二、实验内容
+-
+根据选题要求使用文件存储
+
+将应用产生的数据保存到文件存储中；<br>
+说明使用的文件存储方式：内部 or 外部；<br>
+将运行结果截图。<br>
+三、实验步骤
+-
+Item添加监听，获取Item内容，将其保存为字符串msg<br>
+通过 openFileOutput("record.txt",MODE_PRIVATE);创建一个FileOutStream的对象fos，第一个参数是文件名，第二个参数是文件打开方式<br>
+将msg.getBytesz转换成字节型数据,fos.write()将其写入文件中<br>
+读取文件时，创建Stringbuilder对象，逐一接收openFileInput对象中文件的内容，返回其内容字符串类型 <br>
+四、实验截图

+五、实验体会
+-
+学会了Android的文件存储，由于先前学过Java输入输出流，所以感觉并不怎么困难
