要读取内部存储的数据，你需要你的应用程序文件夹和读取从这里含量

To read data from internal storage you need your app files folder and read content from here

String yourFilePath = context.getFilesDir() + "/" + "hello.txt";

File yourFile = new File( yourFilePath );

你也可以使用这个方法

Also you can use this approach

   FileInputStream fis = context.openFileInput("hello.txt", Context.MODE_PRIVATE);
   InputStreamReader isr = new InputStreamReader(fis);
   BufferedReader bufferedReader = new BufferedReader(isr);
   StringBuilder sb = new StringBuilder();
   String line;
   while ((line = bufferedReader.readLine()) != null) {
       sb.append(line);
   }
