Android查看文本文件问题 [英] Android view text file issue

问题描述

我可以在textview中看到我的文本文件，但是我希望以与在屏幕上看不到我的文件相同的方式进行打印...
我要查看文件的代码是

尝试{
资源res = getResources();
InputStream in_s = res.openRawResource(R.raw.report);

byte [] b =新的byte [in_s.available()];
in_s.read(b);
read.setText(new String(b));
} catch(Exception e){
//e.printStackTrace();
// 这是textview设置的文本文件视图
read.setText(错误:无法显示帮助.");

I can see my text file in textview but i want to print in same manner as in file which is not seeing me on screen ...
my code to see file is

try {
Resources res = getResources();
InputStream in_s = res.openRawResource(R.raw.report);

byte[] b = new byte[in_s.available()];
in_s.read(b);
read.setText(new String(b));
} catch (Exception e) {
// e.printStackTrace();
//this is textview set text file view
read.setText("Error: can''t show help.");

推荐答案

// try opening the myfilename.txt
  try {
    // open the file for reading
    InputStream instream = openFileInput("myfilename.txt");
 
    // if file the available for reading
    if (instream) {
      // prepare the file for reading
      InputStreamReader inputreader = new InputStreamReader(instream);
      BufferedReader buffreader = new BufferedReader(inputreader);
                 
      String line;
 
      // read every line of the file into the line-variable, on line at the time
      while (( line = buffreader.readLine())) {
        // do something with the settings from the file
      }
 
    }
     
    // close the file again       
    instream.close();
  } catch (java.io.FileNotFoundException e) {
    // do something if the myfilename.txt does not exits
  }
