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();
}
@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);
}

您可以像在textview中设置文本一样设置edittext的文本,因此只需在您希望调用它的地方调用
a.setText(textFromYourTextView)
。然后您可以使用处理程序将操作延迟几秒钟,如本示例所示:在Android中5秒后执行函数
然后在处理程序代码中使用
.callOnClick()
方法调用按钮的onclick。eh57zj3b2#
我设法解决了这个问题,
在上面的代码中,只要提到
TextView
和result_field
,我就用EditText
和TFusername
替换它希望这能让其他遇到同样问题的人更清楚
