推荐答案

下面介绍如何在一个文件中写入。

Here's how to write in a file..

FileOutputStream fos = openFileOutput("urls.txt", Context.MODE_PRIVATE);
fos.write("Alex".getBytes());
fos.close();

下面是如何读取该文件：

Here's how to read that file:

FileInputStream fis = openFileInput("urls.txt");
int c;
while((c=fis.read())!=-1)
        {

            k += (char)c;
        }
fis.close();

字符串-k将包含ANKIT作为一个字符串。

String k will contain "Ankit" as a string.

你..文件urls.txt被形成在手机内存中的心灵，你不能访问该文件在您的项目作为一种资源。

Mind you.. the file "urls.txt" gets formed in the phone memory, you cannot access that file in your project as a resource.
