Android 读取指定路径文件

     /**

     * 文件读取
     *
     * @param dataFileName
     */
    private void Dataprocessing(String dataFileName) {
     
        String tempFile = dataFileName.trim();
        if (tempFile.length() == 0)
            return;
        File file = new File(tempFile);
        try {
            InputStream stream2 = new FileInputStream(file);
            //处理业务
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        }


    }

调用时 

Dataprocessing（传入文件路径）；如："/storage/emulated/0/pms/test.xml"
