android从资源文件中读取文件流并显示的方法

private void doRaw(){  InputStream is = this.getResources().openRawResource(R.raw.ziliao);  try{    doRead(is);  }catch(IOException e){    e.printStackTrace();  }}private void doRead(InputStream is) throws IOException{  DataInputStream dis = new DataInputStream(is);  byte[]buffer = new byte[is.available()];  dis.readFully(buffer);   textView.setText(new String(buffer));  dis.close();  is.close();}//就是用this.getResources().openRawResource这个就可以了
