Question

我正在尝试创建一个用于实现语音命令功能的基本应用程序，并且到目前为止已经有了一些基本功能。目前，如果我说'开放语音命令＆＃39;此文字显示在＆＃39; TextView＆＃39;带有id＆＃39; result_text＆＃39;。

的字段

我想传递＆＃39; TextView＆＃39;中显示的文字。进入＆＃39; EditText＆＃39;字段名为＆＃39; TFusername＆＃39;然后自动触发一个名为“bVoice”的按钮按下。 1-2秒后。

这可以很容易地实现到我现在的代码中，如下所示：

public class PocketSphinxActivity extends Activity implements RecognitionListener {


private static final String KWS_SEARCH = "wakeup";

/* Keyword we are looking for to activate menu */
private static final String KEYPHRASE = "open voice command";   //adjust this keyphrase!

private SpeechRecognizer recognizer;
private HashMap<String, Integer> captions;

ListView lv;
TextView tv;
EditText a;
Button b;
Button c;


@Override
public void onCreate(Bundle state) {
    super.onCreate(state);

    // Prepare the data for UI
    captions = new HashMap<String, Integer>();
    captions.put(KWS_SEARCH, R.string.kws_caption);
    setContentView(R.layout.main);
    ((TextView) findViewById(R.id.caption_text))
            .setText("Preparing the recognizer");

    lv = (ListView) findViewById(R.id.lvVoiceReturn);
    a = (EditText) findViewById(R.id.TFusername);
    b = (Button) findViewById(R.id.bVoice);
    c = (Button)findViewById(R.id.Blogin);


    // Recognizer initialization is a time-consuming and it involves IO,
    // so we execute it in async task

    new AsyncTask<Void, Void, Exception>() {
        @Override
        protected Exception doInBackground(Void... params) {
            try {
                Assets assets = new Assets(PocketSphinxActivity.this);
                File assetDir = assets.syncAssets();
                setupRecognizer(assetDir);
            } catch (IOException e) {
                return e;
            }
            return null;
        }

        @Override
        protected void onPostExecute(Exception result) {
            if (result != null) {
                ((TextView) findViewById(R.id.caption_text))
                        .setText("Failed to init recognizer " + result);
            } else {
                switchSearch(KWS_SEARCH);
            }
        }
    }.execute();
}

@Override
public void onDestroy() {
    super.onDestroy();
    recognizer.cancel();
    recognizer.shutdown();
}

/**
 * In partial result we get quick updates about current hypothesis. In
 * keyword spotting mode we can react here, in other modes we need to wait
 * for final result in onResult.
 */
@Override
public void onPartialResult(Hypothesis hypothesis) {
    if (hypothesis == null)
        return;

    String text = hypothesis.getHypstr();
    ((TextView) findViewById(R.id.result_text)).setText(text);
}

/**
 * This callback is called when we stop the recognizer.
 */
@Override
public void onResult(Hypothesis hypothesis) {
    ((TextView) findViewById(R.id.result_text)).setText("");
    if (hypothesis != null) {
        String text = hypothesis.getHypstr();
        makeText(getApplicationContext(), text, Toast.LENGTH_SHORT).show();
    }
}

@Override
public void onBeginningOfSpeech() {
}

/**
 * We stop recognizer here to get a final result
 */
@Override
public void onEndOfSpeech() {
    if (!recognizer.getSearchName().equals(KWS_SEARCH))
        switchSearch(KWS_SEARCH);
}

private void switchSearch(String searchName) {
    recognizer.stop();

    // If we are not spotting, start listening with timeout (10000 ms or 10 seconds).
    if (searchName.equals(KWS_SEARCH))
        recognizer.startListening(searchName);
    else
        recognizer.startListening(searchName, 10000);

    String caption = getResources().getString(captions.get(searchName));
    ((TextView) findViewById(R.id.caption_text)).setText(caption);
}

private void setupRecognizer(File assetsDir) throws IOException {
    // The recognizer can be configured to perform multiple searches
    // of different kind and switch between them

    recognizer = defaultSetup()
            .setAcousticModel(new File(assetsDir, "en-us-ptm"))
            .setDictionary(new File(assetsDir, "cmudict-en-us.dict"))

                    // To disable logging of raw audio comment out this call (takes a lot of space on the device)
            .setRawLogDir(assetsDir)

                    // Threshold to tune for keyphrase to balance between false alarms and misses
            .setKeywordThreshold(1e-45f)

                    // Use context-independent phonetic search, context-dependent is too slow for mobile
            .setBoolean("-allphone_ci", true)

            .getRecognizer();
    recognizer.addListener(this);

    /** In your application you might not need to add all those searches.
     * They are added here for demonstration. You can leave just one.
     */

    // Create keyword-activation search.
    recognizer.addKeyphraseSearch(KWS_SEARCH, KEYPHRASE);

}

@Override
public void onError(Exception error) {
    ((TextView) findViewById(R.id.caption_text)).setText(error.getMessage());
}

@Override
public void onTimeout() {
    switchSearch(KWS_SEARCH);
}

我真的很感激能够轻松实现这一目标的任何人的帮助，谢谢你的进步！

Answer 1

您可以设置edittext的文本，就像在textview中设置它一样，只需调用a.setText(textFromYourTextView)即可调用它。然后，您可以使用处理程序将操作延迟几秒，如下例所示：

Execute function after 5 seconds in Android

然后在处理程序代码中使用.callOnClick()方法调用按钮的onclick。

Answer 2

我设法解决了这个问题，

在上面的代码中，只要它引用了TextView和result_field，我就将其替换为EditText和TFusername
