语音识别器在编辑文本错误中设置文本（Android 工作室）

Question

我正在使用语音识别器使用语音到文本的概念，但是当文本设置为编辑文本时，编辑文本中的现有文本将被删除，并设置从语音转换的文本。但是，我希望将转换后的文本设置在现有文本之后，而不替换现有文本。

public class AddNoteActivity extends AppCompatActivity {
public static final int RECORDAUDIOREQUESTCODE = 1;
private SpeechRecognizer speechRecognizer;
ImageView micButton;

public static final String EXTRA_ID = "EXTRA_ID";

public static final String EXTRA_TITLE =
        "EXTRA_TITLE";
public static final String EXTRA_DESCRIPTION =
        "EXTRA_DESCRIPTION";
private EditText editTextTitle;
private EditText editTextDescription;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_add_note);
    if(ContextCompat.checkSelfPermission(this, Manifest.permission.RECORD_AUDIO)!=
            PackageManager.PERMISSION_GRANTED){
        checkPermission();
    }
    editTextTitle = findViewById(R.id.edit_text_title);
    editTextDescription = findViewById(R.id.edit_text_description);
    Objects.requireNonNull(getSupportActionBar()).setHomeAsUpIndicator(R.drawable.ic_baseline_close_24);
    micButton = findViewById(R.id.mic);
    speechRecognizer = SpeechRecognizer.createSpeechRecognizer(this);
    final Intent speechRecognizerIntent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
    speechRecognizerIntent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
    speechRecognizerIntent.putExtra(RecognizerIntent.EXTRA_LANGUAGE, Locale.getDefault());
    speechRecognizer.setRecognitionListener(new RecognitionListener() {
        @Override
        public void onReadyForSpeech(Bundle params) {

        }

        @Override
        public void onBeginningOfSpeech() {
            editTextDescription.setSelection(editTextDescription.getText().length());
        }

        @Override
        public void onRmsChanged(float rmsdB) {

        }

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

        }

        @Override
        public void onEndOfSpeech() {
            editTextDescription.setSelection(editTextDescription.getText().length());
        }

        @Override
        public void onError(int error) {

        }

        @Override
        public void onResults(Bundle results) {
            micButton.setImageResource(R.drawable.ic_baseline_mic_off_24);
            ArrayList<String> data = results.getStringArrayList(SpeechRecognizer.RESULTS_RECOGNITION);
            editTextDescription.setSelection(editTextDescription.getText().length());
            editTextDescription.setText(data.get(0));
        }

        @Override
        public void onPartialResults(Bundle partialResults) {

        }

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

        }
    });
    micButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            micButton.setImageResource(R.drawable.ic_baseline_mic_24);
            speechRecognizer.startListening(speechRecognizerIntent);
        }
    }); 
 @Override
protected void onDestroy(){
    super.onDestroy();
    speechRecognizer.destroy();
}
private void checkPermission(){
    if(Build.VERSION.SDK_INT>=Build.VERSION_CODES.M){
        ActivityCompat.requestPermissions(this,new String[]{Manifest.permission.RECORD_AUDIO},
                RECORDAUDIOREQUESTCODE);
    }
}
 @Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults){
    super.onRequestPermissionsResult(requestCode,permissions,grantResults);
    if(requestCode==RECORDAUDIOREQUESTCODE && grantResults.length>0){
        if(grantResults[0]==PackageManager.PERMISSION_GRANTED)
            Toast.makeText(this, "Permission Granted", Toast.LENGTH_LONG).show();
    }
}

Answer 1

@Override
public void onResults(Bundle results) {
    micButton.setImageResource(R.drawable.ic_baseline_mic_off_24);
    ArrayList<String> data = results.getStringArrayList(SpeechRecognizer.RESULTS_RECOGNITION);
    editTextDescription.setSelection(editTextDescription.getText().length());
    editTextDescription.setText(data.get(0));
}

你告诉它突出显示整个文本，然后设置文本。这将摆脱任何选择（它也是多余的，因为如果您没有设置选择也会发生同样的事情）。如果要继续，请使用

editTextDescription.setText(editTextDescription.getText().toString()+data.get(0))

应该替换该函数的最后两行。它将获取现有文本，将新结果附加到它，并将总字符串设置到视图。
