自定义语音识别对话框
自定义语音识别对话框
提问于 2016-05-08 01:45:44
我想知道是否有任何方法可以在我的应用程序中更改和自定义语音识别对话框的样式？
例如:更改谷歌徽标或文本。
我使用这段代码，它是完整的吗？
public void onReadyForSpeech(Bundle params) {
proccessTXT.setText("Speak now!");
}
@Override
public void onBeginningOfSpeech() {
}
@Override
public void onRmsChanged(float rmsdB) {
}
@Override
public void onBufferReceived(byte[] buffer) {
}
@Override
public void onEndOfSpeech() {
proccessTXT.setText("Waiting");
}
@Override
public void onError(int error) {
proccessTXT.setText(R.string.toast_disconnect);
}
@Override
public void onResults(Bundle results) {
match_text_dialog = new Dialog(MainActivity.this);
match_text_dialog.setContentView(R.layout.dialog_maches_flag);
match_text_dialog.setTitle(R.string.selection_list);
textlist = (ListView) match_text_dialog.findViewById(R.id.list);
matches_text = getIntent().getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
ArrayAdapter adapter = new ArrayAdapter(this,
android.R.layout.simple_list_item_1, matches_text);
textlist.setAdapter(adapter);
textlist.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView parent, View view,
int position, long id) {
type_texts = matches_text.get(position);
speech_text.append(type_texts + " ");
match_text_dialog.hide();
// speech_text.setCustomSelectionActionModeCallback(new SelectText());
actionMode = MainActivity.this.startActionMode(new SelectText());
}
});
match_text_dialog.show();// show dialog
}
@Override
public void onPartialResults(Bundle partialResults) {
}这是LogCat：

作为一个选项，您可以使用以下命令启动语音识别器ACTION_RECOGNIZE_SPEECH(无UI)并显示所需的任何对话框
SpeechRecognizer speechRecognizer = SpeechRecognizer.createSpeechRecognizer(this);
speechRecognizer.setRecognitionListener(this);
Intent speechIntent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
speechIntent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
speechIntent.putExtra(RecognizerIntent.EXTRA_CALLING_PACKAGE, this.getPackageName());
speechRecognizer.startListening(speechIntent);在这里，您需要实现RecognitionListener
因此，您可以在public void onReadyForSpeech(Bundle params)
回调。取消public void onResults(Bundle results)
或者public void onError(int error)

//use this for implementing speech to text translation in android via java
micbtn.setOnClickListener(v -> {
Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE, "en-US");
try {
startActivityForResult(intent, 1);
input.setText("");
} catch (ActivityNotFoundException e) {
Toast.makeText(getApplicationContext(), "Your Device doesn't Support this Feature", Toast.LENGTH_LONG).show();
e.printStackTrace();
}
});
@Override
protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data ) {
super.onActivityResult(requestCode, resultCode, data);
switch(requestCode) {
case 1:
if (resultCode == RESULT_OK && data != null) {
ArrayList info = data . getStringArrayListExtra (RecognizerIntent.EXTRA_RESULTS);
input.setText(info.get(0).replaceAll("\\s", "").toUpperCase());
}
break;
}
