android 文件的读写--调用android自带的文件管理器选择文本文件读写从操作

[朔北冥]

这个天尝试着调用android自带的文件文件管理器读取文本文件----其中碰到了些问题--特来求助！！！！

其中调用文件管理器获取文件路径的代码：

private void chooseFile() {
        Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
        intent.setType("*/*");
        intent.addCategory(Intent.CATEGORY_OPENABLE);
        try {
            startActivityForResult(Intent.createChooser(intent, "选择文件"), FILE_SELECT_CODE);
        } catch (android.content.ActivityNotFoundException ex) {
            Toast.makeText(this, "没有文件管理器，请安装", Toast.LENGTH_SHORT).show();
        }
    }

    @Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        // TODO Auto-generated method stub
        if (resultCode != Activity.RESULT_OK) {
            Log.e(TAG, "onActivityResult() error, resultCode: " + resultCode);
            super.onActivityResult(requestCode, resultCode, data);
            return;
        }
        if (requestCode == FILE_SELECT_CODE) {
            Uri uri = data.getData();
            openFile=uri.getPath();
            Log.i(TAG,"-------->"+uri.toString());
            Log.i(TAG, "------->" + uri.getPath());
            originalContent = FileOperation.read(openFile);
            originalText.setText(originalContent);
        }
        super.onActivityResult(requestCode, resultCode, data);
    }

读取文本代码：

 public static String read(String fileName){
        String path = fileName;
        String content = ""; 
        
        File file = new File(path);
        if (file.isDirectory())
        {
            Log.d("TestFile", "The File doesn't not exist.");
        }
        else
        {
            try {
                InputStream instream = new FileInputStream(file);
                if (instream != null)
                {
                    InputStreamReader inputreader = new InputStreamReader(instream);
                    BufferedReader buffreader = new BufferedReader(inputreader);
                    String line;
                    while (( line = buffreader.readLine()) != null) {
                        content += line + "\n";
                    }
                    instream.close();
                }
            }
            catch (FileNotFoundException e)
            {
                Log.d("TestFile", "The File doesn't not exist.");
            }
            catch (IOException e)
            {
                Log.d("TestFile", e.getMessage());
            }
        }
        return content;
    }

输出返回的URL.getPaht();url.toString() 发现路径皆不正常不知道哪里错了
