这是从语音到文本的基本实现。按下按钮，它会录制声音并将单词显示为文本。
它在android 8上完美运行，并且仍然在运行Oreo的设备上运行，但是当我尝试在使用android 9 Pie的设备上运行它时，应用程序崩溃了。代码是100％一样，我还没有改变。
清单文件的补充：
<uses-permission android:name="android.permission.RECORD_AUDIO" />
Java：
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
checkPermission();
final EditText editText = findViewById(R.id.editText);
final SpeechRecognizer mSpeechRecognizer = SpeechRecognizer.createSpeechRecognizer(this);
final Intent mSpeechRecognizerIntent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
mSpeechRecognizerIntent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,
RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
mSpeechRecognizerIntent.putExtra(RecognizerIntent.EXTRA_LANGUAGE,
Locale.getDefault());
mSpeechRecognizer.setRecognitionListener(new RecognitionListener() {
@Override
public void onReadyForSpeech(Bundle bundle) {
}
@Override
public void onBeginningOfSpeech() {
}
@Override
public void onRmsChanged(float v) {
}
@Override
public void onBufferReceived(byte[] bytes) {
}
@Override
public void onEndOfSpeech() {
}
@Override
public void onError(int i) {
}
@Override
public void onResults(Bundle bundle) {
//getting all the matches
ArrayList<String> matches = bundle
.getStringArrayList(SpeechRecognizer.RESULTS_RECOGNITION);
//displaying the first match
if (matches != null)
editText.setText(matches.get(0));
}
@Override
public void onPartialResults(Bundle bundle) {
}
@Override
public void onEvent(int i, Bundle bundle) {
}
});
findViewById(R.id.button).setOnTouchListener(new View.OnTouchListener() {
@Override
public boolean onTouch(View view, MotionEvent motionEvent) {
switch (motionEvent.getAction()) {
case MotionEvent.ACTION_UP:
mSpeechRecognizer.stopListening();
editText.setHint("You will see input here");
break;
case MotionEvent.ACTION_DOWN:
mSpeechRecognizer.startListening(mSpeechRecognizerIntent);
editText.setText("");
editText.setHint("Listening...");
break;
}
return false;
}
});
}
private void checkPermission() {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
if (!(ContextCompat.checkSelfPermission(this, Manifest.permission.RECORD_AUDIO) == PackageManager.PERMISSION_GRANTED)) {
Intent intent = new Intent(Settings.ACTION_APPLICATION_DETAILS_SETTINGS,
Uri.parse("package:" + getPackageName()));
startActivity(intent);
finish();
}
}
}
}
我知道发布整个代码文本是不常见的做法，但是我没有其他办法让您知道Android 9可能缺少的内容。
