I have a txt file named "codecs", size is 3M, under the directory "res/
raw/".
This file has been splited to 25 files by the first character of each
line, such as "codecs_a, codecs_b, codecs_c, ......, codecs_y".
And,each of the files contents are sorted by the first colum (ASC).
Now, I use the folowing code to read the file content.
InputStream is = Resources. openRawResource(R.raw.codecs_a);
InputStreamReader isr = new InputStreamReader(is , Charset.forName
("UTF-8"));
BufferedReader br = new BufferedReader(isr );
....
br.readLine(); //get file content line by line
....
In this method , when I input a number(the first column of the file
content), I can access the content . But it is so slow.......
For example:
Contents of file "codecs_a" :
----------------------------------------------------------------------------------------------------
COLUMN 1 COLUMN 2 COLUMN 3
----------------------------------------------------------------------------------------------------
1 This is the first line.

When I input 1 or 2, search speed is fast , but when I input 10254525,
it's so long time to wait for search result.
Is there any way to improve this program?
Thanks for your attention!
