ANDROID。如何在不出现谷歌弹出窗口的情况下对文本进行语音输入？

Question

你好安卓开发者，

我是 android 开发的初学者。遇到这个问题 -

我想将语音输入文本，但我不希望出现 google 弹出窗口。我见过很多有语音输入但没有语音输入的应用，所以请问有人能帮我解决这个问题吗？

这里是弹出窗口的截图

这是我的MainActivity代码

公共(public)类 MainActivity 扩展 AppCompatActivity {

private TextView resultTV;

/**
 * ATTENTION: This was auto-generated to implement the App Indexing API.
 * See https://g.co/AppIndexing/AndroidStudio for more information.
 */
private GoogleApiClient client;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    // ATTENTION: This was auto-generated to implement the App Indexing API.
    // See https://g.co/AppIndexing/AndroidStudio for more information.
    client = new GoogleApiClient.Builder(this).addApi(AppIndex.API).build();
    resultTV = (TextView) findViewById(R.id.resultTV);
}


public void onButtonClick(View view) {

    if (view.getId() == R.id.imageButton) {

        promtSpeechInput();

    }


}

public void promtSpeechInput() {

    Intent i = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
      i.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
      i.putExtra(RecognizerIntent.EXTRA_LANGUAGE, Locale.getDefault());
      i.putExtra(RecognizerIntent.EXTRA_PROMPT, "SAY SOMETHING");
      i.putExtra(RecognizerIntent.EXTRA_PARTIAL_RESULTS, true);



    try {

        startActivityForResult(i, 100);
        Toast.makeText(MainActivity.this, "Say something kiddo", Toast.LENGTH_LONG).show();



    } catch (Exception e) {
        Toast.makeText(MainActivity.this, "Sorry, your device not support speech inputs", Toast.LENGTH_LONG).show();
        e.printStackTrace();
    }


}


public void onActivityResult(int request_code, int result_code, Intent i){


        super.onActivityResult(request_code,result_code,i);

        switch (request_code)
        {

            case 100: if(result_code == RESULT_OK && i != null){
                ArrayList<String> result = i.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);

                resultTV.setText(result.get(0));

            }
            break;

        }

尝试使用我创建的这个 Activity ，当切换按钮打开时，录音开始，并且使用 RmsChanged() 方法在进度条中显示语音音高的波动，识别的文本显示在 TextView 中

public class MainActivity extends Activity implements RecognitionListener
{
private TextView returnedText;
private ToggleButton toggleButton;
private ProgressBar progressBar;
private SpeechRecognizer speech = null;
private Intent recognizerIntent;
private String LOG_TAG = "VoiceRecognitionActivity";

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    returnedText = (TextView) findViewById(R.id.textView1);
    progressBar = (ProgressBar) findViewById(R.id.progressBar1);
    toggleButton = (ToggleButton) findViewById(R.id.toggleButton1);
    Button recordbtn = (Button) findViewById(R.id.mainButton);


    progressBar.setVisibility(View.INVISIBLE);
    speech = SpeechRecognizer.createSpeechRecognizer(this);
    speech.setRecognitionListener(this);
    recognizerIntent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
    recognizerIntent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_PREFERENCE,
                              "en");
    recognizerIntent.putExtra(RecognizerIntent.EXTRA_CALLING_PACKAGE,
                              this.getPackageName());
    recognizerIntent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,
                              RecognizerIntent.LANGUAGE_MODEL_WEB_SEARCH);
    recognizerIntent.putExtra(RecognizerIntent.EXTRA_PARTIAL_RESULTS, true);
    recognizerIntent.putExtra(RecognizerIntent.EXTRA_SPEECH_INPUT_MINIMUM_LENGTH_MILLIS, 3000);

    toggleButton.setOnCheckedChangeListener(new OnCheckedChangeListener() {

            @Override
            public void onCheckedChanged(CompoundButton buttonView,
                                         boolean isChecked) {
                if (isChecked) {
                    progressBar.setVisibility(View.VISIBLE);
                    progressBar.setIndeterminate(true);
                    speech.startListening(recognizerIntent);
                } else {
                    progressBar.setIndeterminate(false);
                    progressBar.setVisibility(View.INVISIBLE);
                    speech.stopListening();
                }
            }
        });






}

@Override
public void onResume() {
    super.onResume();
}

@Override
protected void onPause() {
    super.onPause();
    if (speech != null) {
        speech.destroy();
        Log.i(LOG_TAG, "destroy");
    }

}

@Override
public void onBeginningOfSpeech() {
    Log.i(LOG_TAG, "onBeginningOfSpeech");
    progressBar.setIndeterminate(false);
    progressBar.setMax(10);
}

@Override
public void onBufferReceived(byte[] buffer) {
    Log.i(LOG_TAG, "onBufferReceived: " + buffer);
}

@Override
public void onEndOfSpeech() {
    Log.i(LOG_TAG, "onEndOfSpeech");
    progressBar.setIndeterminate(true);
    toggleButton.setChecked(false);
}

@Override
public void onError(int errorCode) {
    String errorMessage = getErrorText(errorCode);
    Log.d(LOG_TAG, "FAILED " + errorMessage);
    returnedText.setText(errorMessage);
    toggleButton.setChecked(false);
}

@Override
public void onEvent(int arg0, Bundle arg1) {
    Log.i(LOG_TAG, "onEvent");
}

@Override
public void onPartialResults(Bundle arg0) {
    Log.i(LOG_TAG, "onPartialResults");
ArrayList<String> matches = arg0
        .getStringArrayList(SpeechRecognizer.RESULTS_RECOGNITION);
    String text = "";
    for (String result : matches)
        text += result + "\n";

    returnedText.setText(text);


}

@Override
public void onReadyForSpeech(Bundle arg0) {
    Log.i(LOG_TAG, "onReadyForSpeech");
}

@Override
public void onResults(Bundle results) {
    Log.i(LOG_TAG, "onResults");

}

@Override
public void onRmsChanged(float rmsdB) {
    Log.i(LOG_TAG, "onRmsChanged: " + rmsdB);
    progressBar.setProgress((int) rmsdB);

}

public static String getErrorText(int errorCode) {
    String message;
    switch (errorCode) {
        case SpeechRecognizer.ERROR_AUDIO:
            message = "Audio recording error";
            break;
        case SpeechRecognizer.ERROR_CLIENT:
            message = "Client side error";
            break;
        case SpeechRecognizer.ERROR_INSUFFICIENT_PERMISSIONS:
            message = "Insufficient permissions";
            break;
        case SpeechRecognizer.ERROR_NETWORK:
            message = "Network error";
            break;
        case SpeechRecognizer.ERROR_NETWORK_TIMEOUT:
            message = "Network timeout";
            break;
        case SpeechRecognizer.ERROR_NO_MATCH:
            message = "No match";
            break;
        case SpeechRecognizer.ERROR_RECOGNIZER_BUSY:
            message = "RecognitionService busy";
            break;
        case SpeechRecognizer.ERROR_SERVER:
            message = "error from server";
            break;
        case SpeechRecognizer.ERROR_SPEECH_TIMEOUT:
            message = "No speech input";
            break;
        default:
            message = "Didn't understand, please try again.";
            break;
    }
    return message;
}
