我需要从电话记忆中读到档案。 如何阅读档案? 谁能帮助我?

最佳回答

这里指的是如何在档案中写字。

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

这里读到该档案:

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

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

坚固k将包含“Ankit”作为str。

您,“urls.txt”文档在电话记忆中形成,你无法作为资源在你的项目中查阅。

阅读内部储存的档案:

  1. Call openFileInput() and pass it the name of the file to read. This returns a FileInputStream.
  2. Read bytes from the file with read().
  3. Then close the stream with close().
