Question

I need to show only the first entry from Arraylist.

My code below shows all the results but I need only the first entry from the list.

wordsList is the name of ListView:

ArrayList <<String>> matches = data.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);

wordsList.setAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1,matches));

---

Full method code:

protected void onActivityResult(int requestCode, int resultCode, Intent data) 
{
    if (requestCode == REQUEST_CODE && resultCode == RESULT_OK) 
    { 
        // Populate the wordsList with the String values the recognition engine thought it heard 
        ArrayList<String> matches = data.getStringArrayListExtra( RecognizerIntent.EXTRA_RESULTS); 
        wordsList.setAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, matches.get(0)));
    }
}

Since you are only wanting the first element from the ArrayList<String> matches then you just need to create a new List<String> and add the first element to the new List.

Then use that new List for the Adapter.

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == REQUEST_CODE && resultCode == RESULT_OK) { 
        // Populate the wordsList with the String values the recognition engine thought it heard 
        ArrayList<String> matches = 
                data.getStringArrayListExtra( RecognizerIntent.EXTRA_RESULTS);

        if (matches.size() > 0) {
            List<String> oneMatch = new ArrayList<String>();
            oneMatch.add(matches.get(0));

            wordsList.setAdapter(
                new ArrayAdapter<String>(
                     this, android.R.layout.simple_list_item_1, oneMatch));
        } else {
            Log.e(TAG, "Matches does not contain any values.");
        }
    }
}
