我试图创建一个基本的应用程序，用于实现语音命令功能，到目前为止已经得到了一些基本的功能工作。目前，如果我说'打开语音命令'这个文本出现在一个TextView字段与id result_text。
我想将TextView中显示的文本传递到名为TFusername的EditText字段中，然后在1-2秒后自动触发名为bVoice的按钮。
这可以很容易地实现到我目前的代码，我已经显示在下面？

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();
}

    if (hypothesis == null)
        return;

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

/**

@Override
