How do I reduce this code duplication

How do I reduce this code duplication - java

I'm stuck on how I can reduce this code duplication, I'm using the TextToSpeech engine and using locales so the user can select their language.
language is a Spinner.
language.setOnItemSelectedListener(new OnItemSelectedListener() {
public void onItemSelected(AdapterView<?> parent, View arg1,
int pos, long id) {
System.out.println(parent.getItemAtPosition(pos).toString());
if (parent.getItemAtPosition(pos).toString().equals("UK")) {
textToSpeech = new TextToSpeech(MainActivity.this,
new TextToSpeech.OnInitListener() {
#Override
public void onInit(int status) {
if (status != TextToSpeech.ERROR) {
textToSpeech.setLanguage(Locale.UK);
}
}
});
} else if (parent.getItemAtPosition(pos).toString()
.equals("US")) {
textToSpeech = new TextToSpeech(MainActivity.this,
new TextToSpeech.OnInitListener() {
#Override
public void onInit(int status) {
if (status != TextToSpeech.ERROR) {
textToSpeech.setLanguage(Locale.US);
}
}
});
} else if (parent.getItemAtPosition(pos).toString()
.equals("French")) {
textToSpeech = new TextToSpeech(MainActivity.this,
new TextToSpeech.OnInitListener() {
#Override
public void onInit(int status) {
if (status != TextToSpeech.ERROR) {
textToSpeech.setLanguage(Locale.FRANCE);
}
}
});
} else if (parent.getItemAtPosition(pos).toString()
.equals("Italian")) {
textToSpeech = new TextToSpeech(MainActivity.this,
new TextToSpeech.OnInitListener() {
#Override
public void onInit(int status) {
if (status != TextToSpeech.ERROR) {
textToSpeech
.setLanguage(Locale.ITALIAN);
}
}
});
} else if (parent.getItemAtPosition(pos).toString()
.equals("German")) {
textToSpeech = new TextToSpeech(MainActivity.this,
new TextToSpeech.OnInitListener() {
#Override
public void onInit(int status) {
if (status != TextToSpeech.ERROR) {
textToSpeech
.setLanguage(Locale.GERMAN);
}
}
});
}
}
public void onNothingSelected(AdapterView<?> arg0) {
// TODO Auto-generated method stub
}
});
}

Extract creation of the TextToSpeech object into a separate function:
private TextToSpeech createTextToSpeech(final Locale loc) {
return new TextToSpeech(MainActivity.this,
new TextToSpeech.OnInitListener() {
#Override
public void onInit(int status) {
if (status != TextToSpeech.ERROR) {
setLanguage(loc);
}
}
});
}
Note that the argument loc must be declared final so that it can be used inside the anonymous class.
Usage:
...
} else if (parent.getItemAtPosition(pos).toString().equals("French")) {
textToSpeech = createTextToSpeech(Locale.FRANCE);
} ...

You can create a Map.
private static final Map<String, Locale> LOCALES = new LinkedHashMap<String, Locale>() {{
put("US", Locale.US);
// many more
}
final Locale locale = LOCALES.get(parent.getItemAtPosition(pos).toString());
if(locale != null)
textToSpeech = new TextToSpeech(MainActivity.this,
new TextToSpeech.OnInitListener() {
#Override
public void onInit(int status) {
if (status != TextToSpeech.ERROR)
textToSpeech.setLanguage(locale);
}
});

from top of my head,
make a Map<String,Locale> where key will be name of country and value will be locale
then just do
textToSpeech = new TextToSpeech(MainActivity.this,
new TextToSpeech.OnInitListener() {
#Override
public void onInit(int status) {
if (status != TextToSpeech.ERROR) {
textToSpeech
.setLanguage(localeMap.get(parent.getItemAtPosition(pos).toString()));
}
}
});

public class TextToSpeechFactory {
private static final Map<String, Locale> LOCALES = new HashMap<String, Locale>() {{
put("US", Locale.US);
// many more
}
};
public static TextToSpeech createInstance(String language){
Locale l = LOCALES.get(language);
if(l == null)
throw new Exception("Languange "+ language + "is not valid!");
else{
return new TextToSpeech(MainActivity.this,
new TextToSpeech.OnInitListener() {
#Override
public void onInit(int status) {
if (status != TextToSpeech.ERROR) {
textToSpeech.setLanguage(l);
}
}
});
}
}
}

Try to use a enum as
public enum LANGLIST {
UK("uk", Locale.UK),
UK("swe", Locale.SWEIDHS);
public String lang;
public Locale loc;
private LANGLIST(String lang, Locale loc) {
this.lang = lang;
this.loc = loc;
}
}
And then loop through all elements in the enum.

Error on the second listen SpeechRecognizer

I have a problem with SpeechRecognizer on android. Here's my code:
public class MyRecognizerListener implements RecognitionListener {
String id;
MyRecognizerListener(String id){
this.id = id;
}
#Override
public void onEndOfSpeech() {
}
#Override
public void onBeginningOfSpeech() {
Log.d("Speech", "Inizia ad Ascoltare");
}
#Override
public void onReadyForSpeech(Bundle params) {
Log.d("Speech", "E' pronto ad Ascoltare");
}
#Override
public void onPartialResults(Bundle results) {
matches = results.getStringArrayList(SpeechRecognizer.RESULTS_RECOGNITION);
if(matches.size() > 1) {
Log.d("Speech", "Risultati Parziali = " + Integer.toString(matches.size()));
for (int i = 0; i < matches.size(); i++) {
Log.d("Speech", matches.get(i));
}
if (matches.contains("si") || matches.contains("sì") || matches.contains("Sì")
|| matches.contains("yes") || matches.contains("ES")) {
Opera opera = createOpera(id);
startAudio(opera);
}
matches = null;
turnSpeechOff = false;
speechRecognizer.cancel();
speechRecognizer.destroy();
speechRecognizer = null;
}
}
#Override
public void onEvent(int eventType, Bundle params) {
}
#Override
public void onError(int error) {
if(turnSpeechOff) {
Log.d("Speech", Integer.toString(error));
turnSpeechOff = false;
speechRecognizer.cancel();
speechRecognizer.destroy();
speechRecognizer = null;
}
}
#Override
public void onRmsChanged(float rmsdB) {
}
#Override
public void onBufferReceived(byte[] buffer) {
}
#Override
public void onResults(Bundle results) {
matches = results.getStringArrayList(SpeechRecognizer.RESULTS_RECOGNITION);
for (int i = 0; i < matches.size(); i++){
Log.d("Parole", matches.get(i));
}
if(matches.contains("si") || matches.contains("sì") || matches.contains("Sì")
|| matches.contains("yes") || matches.contains("ES")){
Opera opera = createOpera(id);
startAudio(opera);
}
matches = null;
turnSpeechOff = false;
speechRecognizer.cancel();
speechRecognizer.destroy();
speechRecognizer = null;
}
}
public void startAudioAsk(final String art_id){
if(speechRecognizer != null) {
return;
}
if(audioPlayer == null || !audioPlayer.isPlaying() ) {
if(operaAudioAsk != null && operaAudioAsk.equals(art_id)){
return;
}
operaAudioAsk = art_id;
if(language.equals("IT")) {
audioPlayer = MediaPlayer.create(this, R.raw.chiedi);
} else {
audioPlayer = MediaPlayer.create(this, R.raw.ask);
}
audioPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
audioPlayer.reset();
audioPlayer.release();
int audioTitle;
if(language.equals("IT")){
audioTitle = getResources().getIdentifier(art_id + "_title" + "_it", "raw", getPackageName());
audioPlayer = MediaPlayer.create(MainActivity.this, audioTitle);
} else {
audioTitle = getResources().getIdentifier(art_id + "_title" + "_en", "raw", getPackageName());
audioPlayer = MediaPlayer.create(MainActivity.this, audioTitle);
}
audioPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
askVoice(art_id);
audioPlayer.reset();
audioPlayer.release();
audioPlayer = null;
}
});
audioPlayer.start();
}
});
audioPlayer.start();
}
}
public void askVoice(String art_id){
if(speechRecognizer == null) {
speechRecognizer = SpeechRecognizer.createSpeechRecognizer(this);
speechRecognizer.setRecognitionListener(new MyRecognizerListener(art_id));
Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
intent.putExtra(RecognizerIntent.EXTRA_CALLING_PACKAGE, getPackageName());
intent.putExtra(RecognizerIntent.EXTRA_PARTIAL_RESULTS, true);
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_WEB_SEARCH);
intent.putExtra(RecognizerIntent.EXTRA_MAX_RESULTS, 3);
intent.putExtra(RecognizerIntent.EXTRA_WEB_SEARCH_ONLY, true);
if(language.equals("IT")){
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE, "it");
} else {
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE, "en_US");
}
speechRecognizer.startListening(intent);
voiceTimer = new Timer();
voiceTimer.schedule(new StopVoiceManager(), 2000);
Log.d("Speech", "Starta");
}
}
public void stopVoice(){
if(speechRecognizer != null){
Log.d("Speech", "Cancello");
turnSpeechOff = true;
speechRecognizer.stopListening();
}
}
public class StopVoiceManager extends TimerTask{
#Override
public void run() {
runOnUiThread(new Runnable() {
#Override
public void run() {
stopVoice();
Log.d("Speech", "Prova a Cancellare");
}
});
}
}
As you can see, there's also a task that, after 2 seconds, calls speechRecognizer.stoplistening().
The first listening is ok, I say "yes" and it recognizes it, but the second listening raises the ERROR_CLIENT and it doesn't recognize anything, then the third listening returns to be ok, the fourth doesn't recognize anything and so.
How can i fix this bug?

TextToSpeech only works when button is pressed, not when called separately

I tried to do something extremely simple or I thought it was.
In my BluetoothChat, I set
public static boolean potato = false;
In the onCreateBundle of my MainActivity, I have
talker = new TextToSpeech(getApplicationContext(),new TextToSpeech.OnInitListener()
{
#Override
public void onInit(int status)
{
if(status != TextToSpeech.ERROR)
{
talker.setLanguage(Locale.US);
}
}
});
if(BluetoothChat.potato == false)
{
speakOut();
}
When speakOut(); is called by a button or separately by itself it works.
public void speakOut()
{
String original ="You will have a seizure in thirty seconds.";
talker.speak(original,TextToSpeech.QUEUE_FLUSH,null);
}
However, this does not work. Can someone explain why?

Thanks to the help from Payeli. Here is the solution! Place the if statement within the onInit.
talker = new TextToSpeech(getApplicationContext(),new TextToSpeech.OnInitListener()
{
#Override
public void onInit(int status)
{
if(status != TextToSpeech.ERROR)
{
talker.setLanguage(Locale.US);
}
if(BluetoothChat.potato == false)
{
speakOut();
}
}
});

How do I reduce this code duplication - java

Try to use a enum as public enum LANGLIST { UK("uk", Locale.UK), UK("swe", Locale.SWEIDHS); public String lang; public Locale loc; private LANGLIST(String lang, Locale loc) { this.lang = lang; this.loc = loc; } } And then loop through all elements in the enum.
