小编Tal*_*eem的帖子

我正在尝试写入我的HTC One上的输出文件并在LogCat中获取以下消息:

11-21 08:05:18.228:W/System.err(6609):java.lang.IllegalArgumentException:File /storage/emulated/0/com.example.pattern1/myfile.txt包含路径分隔符

源代码如下:

    protected void writeToFile(String string){

    File patternDirectory = new File(Environment.getExternalStorageDirectory().getAbsolutePath().toString()+"/com.example.pattern1/myfile.txt");
    patternDirectory.mkdirs();

    FileOutputStream outputStream;

    try {
      outputStream = openFileOutput(patternDirectory.getAbsolutePath().toString(), Context.MODE_APPEND);
      outputStream.write(string.getBytes());
      TextView t = (TextView)findViewById(R.id.bottomMidText);
      t.setText(patternDirectory.getAbsolutePath().toString());
      outputStream.close();

    } catch (Exception e) {
      e.printStackTrace();
    }

如果有人可以帮助确定问题,我将不胜感激.
