Write to a Text File Resource in Android

问题

Does anyone know how to write to a text file in Android using a resource like:

R.raw.my_text_file

I'm just looking for something clean and simple. I've Googled around but the examples I found didn't work. I tried to code using the Android docs but couldn't wrap my head around it...

Thanks

EDIT:

I've used the Android docs to create this code. The logs print out "1" and "9" and the code skips everything in between and does nothing:

    try {
        String filename = "res/raw/my_text_file.txt";
        String string;

        Log.v(TAG, "1");
        FileOutputStream fos = openFileOutput(filename, Context.MODE_PRIVATE);
        Log.v(TAG, "2");

        for (int i = 0; i < list.size(); i++) {
            Log.v(TAG, "3");
            try {
                Log.v(TAG, "4");
                string = i + " - " + list.get(i);
                fos.write(string.getBytes());
            } catch (Exception e) {
                Log.v(TAG, "5");
            }
            Log.v(TAG, "6");
        }
        Log.v(TAG, "7");
        fos.close();
        Log.v(TAG, "8");
    } catch (Exception e) {

    }
    Log.v(TAG, "9");

Resources are read-only at runtime and cannot be written to.

回答2:

As @CommonsWare said you can't write on resources but you could use internal storage using openFileOutput and openFileInput and BufferedReaders and BufferedWriters. You can check it here:

http://developer.android.com/guide/topics/data/data-storage.html#filesInternal

But here's a sample:

BufferedReader BR_intFile = new BufferedReader(new InputStreamReader(openFileInput("file")));

To read and a similar code to write.
