如何将 Speech To Text API 中的文本与 ArrayList/String 数组中的文本进行比较？

Question

到目前为止我的申请的简要说明：

用户说出一个词，这个词将被保存到一个ArrayList结果中，然后它会与存储在wordBank.xml文件中的字符串数组中的词进行比较。如果单词与词库中的单词匹配，那么它将在文本视图中显示单词 "match"，如果不匹配，则将显示 "no match".

问题：问题是在我的 onActivityResult 函数中比较两个数组列表。这是一个运行时间错误，当我尝试启动它时此屏幕崩溃，但是当我更改代码使其不比较时它将运行没有错误。

Main.Java

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 函数

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);
}

有什么想法吗？先感谢您！旁注：最初我没有显示错误消息，因为它是 OnActivityResult 函数中的 if else 语句导致 crash/error.

Answer 1

你的问题就在这里

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

R.array.Words 是资源本身的整数常量，而不是数组的内容。

在代码中解析 XML 数组的正确方法如下：

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

如果您想将 String[] 转换为 ArrayList<String>，请参阅 these examples and a connected question。
