How to compare Text from Speech To Text API to text in a ArrayList/String Array?

Brief Description of my Application so far:

The user will click on the image button which allows the user to speak. The user will say a word the word will be saved into an ArrayList result, then it will compare to the words in the string array which is stored in the wordBank.xml file. If the word matches a word in the wordbank then it will display the word "match" in a textview and if not then it will display "no match".

The issue is comparing the two arraylist, within my onActivityResult function. It is a runtime error, this screen crashes when i try to start it, but when i change the code so it does not compare it will run without an error.

Main.Java

package com.example.speechtotext;
import android.app.Activity;
import android.app.Fragment;
import android.content.ActivityNotFoundException;
import android.content.Intent;
import android.os.Bundle;
import android.speech.RecognizerIntent;
import android.view.LayoutInflater;
import android.view.MenuItem;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ImageButton;
import android.widget.TextView;
import android.widget.Toast;
import java.util.ArrayList;
import java.util.Locale;

public class Main extends Activity {

private static final int VR_Request = 100;

TextView speechInput;
TextView matchOrNot;
ArrayList<String> wordBank;
ImageButton speechBtn;

boolean word = false;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_reverse_pictionary);

speechInput = (TextView) findViewById(R.id.english_word);
matchOrNot = (TextView) findViewById(R.id.matchOrNot);
wordBank = new ArrayList<>(R.array.Words);
speechBtn = (ImageButton) findViewById(R.id.mic_pic_button);

}

public void onMic(View view) {
if (view.getId() == R.id.mic_pic_button) {
promptSpeechInput();
}
}

public void promptSpeechInput() {
Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
intent.putExtra(RecognizerIntent.ACTION_RECOGNIZE_SPEECH, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE, Locale.getDefault());
intent.putExtra(RecognizerIntent.EXTRA_PROMPT, "Say a Word from our word bank!");

try {
startActivityForResult(intent, VR_Request);
} catch (ActivityNotFoundException a) {
Toast.makeText(ReversePictionary.this, "Oopa, your device doesn't support speech recognition,", Toast.LENGTH_LONG).show();
}
}

public void onActivityResult(int requestCode, int resultCode, Intent intent) {

if(requestCode == VR_Request && resultCode == RESULT_OK) {
ArrayList<String> result = intent.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);

if(wordBank.contains(result.get(0))) {
speechInput.setText(result.get(0).toUpperCase());
matchOrNot.setText("MATCH");
}else {
speechInput.setText(result.get(0));
matchOrNot.setText("NO MATCH");
}
}
super.onActivityResult(requestCode, resultCode, intent);
}
}


wordBank.xml

<resources>
<string-array name="Words">
<item>Blue</item>
<item>Yellow</item>
<item>Green</item>
<item>Purple</item>
<item>Brown</item>
<item>White</item>
<item>Black</item>
<item>Pink</item>
</string-array>
</resources>


OnActivityResult Function

public void onActivityResult(int requestCode, int resultCode, Intent intent) {

if(requestCode == VR_Request && resultCode == RESULT_OK) {
ArrayList<String> result = intent.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);

if(wordBank.contains(result.get(0))) {
speechInput.setText(result.get(0).toUpperCase());
matchOrNot.setText("MATCH");
}else {
speechInput.setText(result.get(0));
matchOrNot.setText("NO MATCH");
}
}
super.onActivityResult(requestCode, resultCode, intent);
}

Here is the error message:

Any ideas? Thank you in advance!
Side note: Originally i left the error message out because it was the if else statement within the OnActivityResult function that caused the crash/error.

Answer

Your problem is here

wordBank = new ArrayList<>(R.array.Words);

R.array.Words is an integer constant of the resource itself, not the content of your array.

The correct way to parse an XML array in your code is as follows:

String[] wordBank = getResources().getStringArray(R.array.Words);

If you want to convert String[] to ArrayList<String> see these examples and a connected question.
