自动完成编辑文本-我可以从CSV文件读取吗？

Question

I have a list of ItemCodes that are saved in a CSV file in my raw folder in my android application.

In order to eradicate human error, I would like it so that when the user starts typing the edittext will autocomplete based on the itemcodes in the CSV file.

Does anyone know if this is possible?

Here is what I have so far:

 private void ReadItemCodes() {
    InputStream IS = getResources().openRawResource(R.raw.itemcodes);
    BufferedReader reader = new BufferedReader(new InputStreamReader(IS, Charset.forName("UTF-8")));

    String line;
    try {
        while ((line = reader.readLine()) != null) {
            //Split by commas
            String[] tokens = line.split(",");

            //Read the data
            ItemCodes+=line;  
      }
    } catch (IOException e) {
        e.printStackTrace();
    }
}

If you are just looking for the Suggestion for the AutoComplete Edittext then you can use the string-array , it is easier and if you are having some complex Data Structure then CSV is also good.

For anyone who comes across this in the future. This was the best and simplest approach that I found!

 // Get a reference to the AutoCompleteTextView in the layout
    itemcodetextview = (AutoCompleteTextView) findViewById(R.id.itemcode);
    batchnumbertextview = (AutoCompleteTextView) findViewById(R.id.batchnumber);

    //READ FROM BATCH NUMBER CSV
    Scanner scanner = new Scanner(getResources().openRawResource(R.raw.batchnumbers));
    List<String> listbatchnumbers = new ArrayList<String>();
    while (scanner.hasNext()) {
        listbatchnumbers.add(scanner.next());
    }
    ArrayAdapter<String> adapter =
            new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, listbatchnumbers );
    batchnumbertextview.setAdapter(adapter);
    scanner.close();

    //READ FROM ITEM CODES CSV
    Scanner scanner2 = new Scanner(getResources().openRawResource(R.raw.itemcodesofficial));
    List<String> listitemcodes = new ArrayList<String>();
    while (scanner2.hasNext()) {
        listitemcodes.add(scanner2.next());
    }
    ArrayAdapter<String> adapter2 =
            new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, listitemcodes );
    itemcodetextview.setAdapter(adapter2);
    scanner2.close();
