如何在android中读取CSV文件

Question

timetable.csv文件与MainActivity.java位于同一目录中。 我使用了以下功能。

public void getaction(String date, TextView action1) {

    String line = "";

    String[] football = new String[20];
    try {
        System.out.print("Hello");
        BufferedReader br = new BufferedReader(new FileReader("timetable.csv"));
        String headerLine = br.readLine();
        System.out.print("Hello");
        while ((line = br.readLine()) != null) {
            football = line.split(",");
            //match the date
            if(football[0].equals(date)){
                action1.setText("i found chelsea");
            }else{
                action1.setText("I did not find Chelsea!");
            }
        }


    }
    catch(Exception io){
            System.out.println(io);

        }

    action1.setText("I did too find Chelsea!");
}

它给出了以下错误：

I / System.out：Hellojava.io.FileNotFoundException：timetable.csv（没有这样的文件或目录）

Answer 1

您需要在app模块中创建资源文件夹。 将.csv文件粘贴到那里。 然后你可以读取这样的文件

try
{

reader = new BufferedReader(
    new InputStreamReader(getAssets().open("filename.csv")));
......
}
catch (Exception e)
{

......
}
