Reading a line of a txt file in assets

I have a text file placed in assets and I want to read one line of it at a time. My problem is that I do not know how to access the file in Activity, and then once I access it, how would I go about only selecting one line?

If keeping the txt file in assets is a bad idea, where should I put it for easier a开发者_StackOverflowccess?

I really appreciate any help!

This is a snippet I use to prepopulate tables in my RSS feed reader. You can use it as a track for your needs.

In res/raw/ I have file feeds.txt. The file is referenced is code like R.raw.feeds.

    final Resources resources = mHelperContext.getResources();
    InputStream inputStream = resources.openRawResource(R.raw.feeds);
    BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream), 8192);

    try {
        String line;
        while ((line = reader.readLine()) != null) {
             //make the use you want with "line"
        }
    } catch (IOException e) {
        Log.e(TAG, "Error loading sample feeds.");
        throw new RuntimeException(e);
    }

To open assests, you'll need to call

<context>.getAssets().open(<your file>);

<context> is your activity, so if this is in your onCreate, then it would be this. That call returns an inputstream, which you can then handle however you please.

I don't see how it would be a particularly bad idea to keep your text file there, depends on what you're using that text file for.

Try this:

Make a new method for example readMyFile(). It must looks like this:

private String readMyFile(File file) throws IOException {
     BufferedReader reader = new BufferedReader(new FileReader(file));
     StringBuilder txt = new StringBuilder();
     String line;

     while ((line = reader.readLine()) != null) {
        txt.append(line);
        txt.append("\n");
}

reader.close();
return txt.toString();

Paste it to your code, and use the method (readMyFile([the file what you want to read in assets]).

Hope it helps.
