我碰上了一个我解决不了的文件读取和保存方面的问题,请大家帮我看一下
代码
 public void save__OnClike(View view) {
        try {
            FileOutputStream out = openFileOutput("xyxdata.txt", MODE_PRIVATE);
            String content = TV.getText().toString();           // byte[] bytes = content.getBytes();            out.write(content.getBytes());
            out.flush();
            out.close();        } catch (IOException e) {        }
    }    public void read_text() {
        try {
            FileInputStream inputStream = this.openFileInput("xyxdata.txt");
            byte[] bytes = new byte[1024];
            ByteArrayOutputStream arrayOutputStream = new ByteArrayOutputStream();
            while (inputStream.read(bytes) != -1) {
                arrayOutputStream.write(bytes, 0, bytes.length);
            }
            inputStream.close();
            arrayOutputStream.close();            String content = new String(arrayOutputStream.toByteArray());
            TV.setText(content);        } catch (FileNotFoundException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }    }
