private void readRandomContacts() throws IOException
{
BufferedReader bufRdr;
contacts = new ArrayList<Contacts>();
File randomContactsFile = new File("C:\randomContacts.csv");
try {
bufRdr = new BufferedReader(new FileReader(randomContactsFile));
String line = null;
String[] a = new String[2];
while ((line = bufRdr.readLine()) != null)
{
a = line.split(",");
Contacts c = new Contacts(a[0], a[1], a[1], a[1], a[2]);
contacts.add(c);
}
} catch (FileNotFoundException e) {
Log.d("file not found", "check");
e.printStackTrace();
}
我似乎无法找到该文件,并且randomContacts.csv确实存在于C目录中。有什么帮助吗?

尝试:
File randomContactsFile = new File("C:\\randomContacts.csv");

答案 1 :(得分:1)
File randomContactsFile = new File("C:\randomContacts.csv");
应该是
File randomContactsFile = new File("C:\\randomContacts.csv");
您需要转义\
,否则,java会将\r
作为回车符读取。

你也可以这样做(前言):
new File("C:/randomContacts.csv")
