Hi,
You can do so and here is the idea.
Read the content from file as a string array.
create a list and at the initialization time append the content in the list..

// Code Idea //
examplesList = new List("Select Example", List.IMPLICIT);
for (int i = 0; i < examples.length; i++)
examplesList.append(examples[i], null);

examplesList.setCommandListener(this);

Hope that this is what exactly you are looing for...
Thanks

Hey,
Yeah you can read your file by putting it in SRC folder..No doubt.
What problem you are facing then..are you looking for that how to read that file ..

Thanks

put your .txt file into res folder and call this code

StringBuffer sb = new StringBuffer();
try {
InputStream is = getClass().getResourceAsStream("/Properties.txt");
int ch = 0;

while ((ch = is.read()) != -1) {
sb.append((char) ch);
}
} catch (Exception e) {
e.printStackTrace();
}

You can even use FIle Connection API.

Hey,
I hope i missed you..i was not available.
Anyways hope that you have done with it..still not then see this code

public String readStationsFromTxt ()
{
int ch;
try
{
InputStream inStream = getClass ().getResourceAsStream ("/mumbai_codes.txt");

while ((ch = inStream.read ()) != -1)
{
stationBufferTxt.append ((char) ch);
}
return stationBufferTxt.toString ();
}
catch (Exception e)
{
System.out.println ("Exception caucght file reading..." + e.toString ());
}
return null;
}

Hope that it help you..Now pass this array to the creating of the list..

Query will be answered...

if you are woring with File Connection, then its diffrent procedure.

hi all,

i have 1 text file in the same location where my midlet is.i just want to get the contents of that file and display it on to the List.

i don't think it requires File Connection API's.What all replys are given,i am confused in this.

Hi,
There is no point of be confuse.Just put your file in res folder.Then read the file as per the code that i have given you.That will return you a string/string array.Pass that array to the list creation.As i given you the code -

examplesList = new List("Select Example", List.IMPLICIT);
for (int i = 0; i < examples.length; i++)
examplesList.append(examples[i], null);

all thats you need to do...
Where are you getting confusions.

Thnxs
