OpenCSV 创建.csv文件的位置

Question

我在Eclipse中使用opencsv库，当我在.csv中编写内容时，我不知道是在哪个文件夹中创建的。我应该说我需要在关闭应用程序时不删除.csv文件，以便我可以存储在 assets 文件夹中，对吧？

我的代码是这样的：

try {
    String csv = "data.csv";
    CSVWriter writer = new CSVWriter(new FileWriter(csv));
    //Create record
    String [] record = "hello,world".split(",");
    //Write the record to file
    writer.writeNext(record);
    //close the writer
    writer.close();
} catch (IOException e) {}

Answer 1

也许你可以在"/data/data/your_project_package_structure/files/data.csv"找到它的文件

仍然找不到 你可以这样做。 file.getAbsolutePath（） 为您提供了完整的路径，您可以确定文件的存储位置：

try
{
File file = new File("data.csv");
  // creates the file of name data.csv     
  file.createNewFile();
  //you can print absolute path of file
  System.out.println(file.getAbsolutePath());
  // creates a FileWriter Object
  FileWriter writer = new FileWriter(file); 
  //pass to csv writer
  CSVWriter writer = new CSVWriter(new FileWriter(csv));
              //Create record
              String [] record = "hello,world".split(",");
              //Write the record to file
              writer.writeNext(record);
              //close the writer
              writer.close();
        } catch (IOException e) {
        }
