如何隐藏 Toast 消息“您的音频将被发送到 google 以提供语音识别服务。”在 Android？

Question

我正在使用 google 语音识别器在 Android 中集成语音服务，但是在按下麦克风按钮时显示了这条烦人的消息。请建议我隐藏此吐司消息的方法。

这是我的java代码

public class FormActivity extends AppCompatActivity {

    AppCompatEditText mFeedbackView; 
    ImageView mFeedbackVoiceView;
    private final int REQ_CODE_SPEECH_INPUT_FEEDBACK = 100;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_form);
        Toolbar toolbar = findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);

        mVisitFeedbackView = findViewById(R.id.feedback);
        mFeedbackVoiceView = findViewById(R.id.feedback_voice);

        mFeedbackVoiceView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                promptSpeechInputFeedback();
            }
        });
    }
    private void promptSpeechInputFeedback() {
        Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
        intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
        intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE, Locale.getDefault());
        intent.putExtra(RecognizerIntent.EXTRA_PROMPT, getString(R.string.speech_prompt));
        try {
            startActivityForResult(intent, REQ_CODE_SPEECH_INPUT_FEEDBACK);
        } catch (ActivityNotFoundException a) {
            Toast.makeText(getApplicationContext(), getString(R.string.speech_not_supported), Toast.LENGTH_SHORT).show();
        }
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

        switch (requestCode) {
            case REQ_CODE_SPEECH_INPUT_FEEDBACK: {
                if (resultCode == RESULT_OK && null != data) {
                    ArrayList<String> result = data.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS); 
                    mFeedbackView.setText(result.get(0));
                }
                break;
            }  
        }
    }
}

此问题与 How to hide toast“ Your audio will be sent to google to provide speech recognition service.” in Speech Recognizer? 重复，但没有解决方案。

我们将不胜感激。

Answer 1

基于android 规定您无法隐藏系统提示消息，因为您无权访问系统视图，

只有在你可以访问终端的越狱 android 中，你才可以尝试这样做。

Answer 2

您可以制作自定义语音识别器，这将使您对 UI 有更多的控制权。 MainActivity 打开一个新的 DialogFragment 实现 RecognitionListener 。

public class MainActivity extends AppCompatActivity implements VoiceRecognizerInterface {
    Button button ;
    TextView textView;
    String string;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        button = findViewById(R.id.button);
        textView = findViewById(R.id.textView);
        button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                FragmentManager fragmentManager = getSupportFragmentManager();
                if (fragmentManager != null && fragmentManager.findFragmentByTag("dialogVoiceRecognizer") == null && !isFinishing()) {
                    VoiceRecognizerDialogFragment languageDialogFragment = new VoiceRecognizerDialogFragment(MainActivity.this,MainActivity.this);
                    languageDialogFragment.show(fragmentManager, "dialogVoiceRecognizer");
                }
            }
        });
    }

    @Override
    public void spokenText(String spokenText) {
        textView.setText(spokenText);
    }
}

在 stt.

之后向主 activity 发出信号的接口

public interface VoiceRecognizerInterface {
    void spokenText(String spokenText);
}

自定义 SpeechToText 对话框。

public class VoiceRecognizerDialogFragment extends DialogFragment implements RecognitionListener{

    ImageView micImage;
    TextView stateTV;
    TextView displayTV;

    private SpeechRecognizer mSpeechRecognizer;
    private Intent mSpeechRecognizerIntent;
    private Context context;
    VoiceRecognizerInterface signal;

    @SuppressLint("ValidFragment")
    public VoiceRecognizerDialogFragment(Context context, VoiceRecognizerInterface signal) {
        this.context = context;
        this.signal = signal;
    }

    public VoiceRecognizerDialogFragment(){

    }

    @Nullable
    @Override
    public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.voice_recognizer_custom_layout ,container, false );

        //Mic tap to listen again
        micImage = view.findViewById(R.id.micImageView);
        //Displays Listening.. when recognizer is listening
        stateTV = view.findViewById(R.id.stateTV);
        //Displays message if error
        displayTV = view.findViewById(R.id.displayTV);

        mSpeechRecognizer = SpeechRecognizer.createSpeechRecognizer(context);
        mSpeechRecognizerIntent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
        mSpeechRecognizerIntent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,
                RecognizerIntent.LANGUAGE_MODEL_WEB_SEARCH);
        //Customize language by passing language code
        mSpeechRecognizerIntent.putExtra(RecognizerIntent.EXTRA_LANGUAGE,"en");
        //To receive partial results on the callback
        mSpeechRecognizerIntent.putExtra(RecognizerIntent.EXTRA_PARTIAL_RESULTS,true);
        mSpeechRecognizerIntent.putExtra(RecognizerIntent.EXTRA_CALLING_PACKAGE,
                context.getPackageName());
        mSpeechRecognizer.setRecognitionListener(this);
        mSpeechRecognizer.startListening(mSpeechRecognizerIntent);
        micImage.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                startListening();
            }
        });
        return view;

    }

    public void startListening(){
        mSpeechRecognizer.setRecognitionListener(this);
        mSpeechRecognizer.startListening(mSpeechRecognizerIntent);
        changeUIStateToListening();
    }


    @Override
    public void onDestroy() {
        super.onDestroy();
        if (mSpeechRecognizer != null) {
            mSpeechRecognizer.destroy();
        }
    }

    @Override
    public void onBeginningOfSpeech()
    {
    }

    @Override
    public void onBufferReceived(byte[] buffer)
    {

    }

    @Override
    public void onEndOfSpeech()
    {
    }

    @Override
    public void onError(int error)
    {
        if(error == 7){
           changeUIStateToRetry();
        }
    }

    @Override
    public void onEvent(int eventType, Bundle params)
    {

    }

    @Override
    public void onPartialResults(Bundle partialResults) {
    }

    @Override
    public void onReadyForSpeech(Bundle params)
    {

    }

    @Override
    public void onResults(Bundle results)
    {
        ArrayList<String> matches = results.getStringArrayList(SpeechRecognizer.RESULTS_RECOGNITION);
        if(matches == null){
            return;
        }
        int i =0;
        String first ="";
        for(String s : matches){
            if(i==0){
                first = s;
            }
            i++;
        }
        // sending text to MainActivity using Interface
        signal.spokenText(first);
        this.dismiss();
    }

    @Override
    public void onRmsChanged(float rmsdB)
    {
    }

    public void changeUIStateToListening(){
        displayTV.setText("Tell us what you need");
        stateTV.setText("Listening...");
    }

    public void changeUIStateToRetry(){
        displayTV.setText("Didn't catch that. Try\nSpeaking again");
        stateTV.setText("Tap on mic to try again");
