It seems to me that the method "speak" of class TextToSpeech only works in method onInit or onUtteranceCompleted. However, onInit and onUtteranceCompleted don t have any parameter for passing strings.
In the following code, I tried to define a global string arraylist outside the methods and used the arraylist for string input.For some reason , it didn t work out.But the engine did speak "did you sleep well". Any help is appreciated.
public class TTS extends Activity implements OnInitListener,OnUtteranceCompletedListener,Runnable {
ArrayList<String> content=new ArrayList<String>();
int MY_DATA_CHECK_CODE=50;
private TextToSpeech mTts;
public void onCreate(Bundle savedInstanceState) {
content.add("test");
content.add("another test");
super.onCreate(savedInstanceState);
setContentView(R.layout.splash);
Intent checkIntent = new Intent();
checkIntent.setAction(TextToSpeech.Engine.ACTION_CHECK_TTS_DATA);
startActivityForResult(checkIntent, MY_DATA_CHECK_CODE);
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == MY_DATA_CHECK_CODE) {
if (resultCode == TextToSpeech.Engine.CHECK_VOICE_DATA_PASS) {
// success, create the TTS instance
mTts = new TextToSpeech(this,this);
} else {
// missing data, install it
Intent installIntent = new Intent();
installIntent.setAction(
TextToSpeech.Engine.ACTION_INSTALL_TTS_DATA);
startActivity(installIntent);
}
}
}
public void onInit(int status){
if(status==TextToSpeech.SUCCESS){
mTts.setLanguage(Locale.US);
mTts.setOnUtteranceCompletedListener(this);
String myText1 = "Did you sleep well?";
mTts.speak(myText1, TextToSpeech.QUEUE_FLUSH, null);
for(int i=0;i<content.size();i++){
mTts.speak(content.get(i),TextToSpeech.QUEUE_ADD,null);
}
if(status==TextToSpeech.ERROR){
mTts.shutdown();
}
}
}
