android - 自定义语音识别对话框

Question

我想知道是否有任何方法可以更改和自定义我的应用程序中语音识别对话框的样式？

即:更改 Google Logo 或文本。

我使用这个代码，它完整吗？

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<String> adapter = new ArrayAdapter<String>(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:

Answer 1

作为一个选项，您可以使用 ACTION_RECOGNIZE_SPEECH(无 UI)启动语音识别器并显示您需要的任何对话框

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);

这里您需要实现RecognitionListener 以便您可以在public void onReadyForSpeech(Bundle params) 回调中显示对话框。在 public void onResults(Bundle results) 或 public void onError(int error)

中关闭
