Well... I am trying to create an application using the TTS Engine.
I can already make it, work, no problem. However I need my buttons to be
dinamic, they will come from a database.
**So far you guys have helped me a lot, since now I can do it thanks to the
tips I got from you guys.**
**Well.. now I am stuck again.**
Every new button that I create I attach an OnClickListener so it can start
the TTS and speak something.
However it's an inner method, so, when I try to run the code below, it
gives me a NullPointerException when it tries to "speak" using the TTS. I
know the TTS object is out of context, so, **How can I solve this?**
Below the code. It's a little big since I wanted to include everything:
PLEASE JUMP TO THE "HERE IS MY PROBLEM!!!" comment so you guys can see
exactly where my problem is. I know where it is, but I don't know how to
solve it =(
Any help is appreciatted! =)
public class LivoxTesteActivity extends Activity implements
OnInitListener{
/** Called when the activity is first created. */
private int MY_DATA_CHECK_CODE = 0;
public TextToSpeech tts;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.main);
LinearLayout lgeral = new LinearLayout (this);
lgeral.setOrientation(LinearLayout.VERTICAL);
lgeral.setLayoutParams(new
LinearLayout.LayoutParams(LayoutParams.FILL_PARENT,
LayoutParams.FILL_PARENT, 1f));
String array[][] = {{"Comer","eat", "Eu quero comer", "1"},

{"Beber","drink", "Eu quero beber", "4"}};
int x = array.length;
int qtdeLinhas = 2;
for (int j = 0; j < qtdeLinhas; j++) {
LinearLayout l1 = new LinearLayout (this);
l1.setOrientation(LinearLayout.HORIZONTAL);
l1.setLayoutParams(new
LinearLayout.LayoutParams(LayoutParams.FILL_PARENT,
LayoutParams.FILL_PARENT, 1f));
FrameLayout fl;
for (int i = 0; i < array.length; i++) {
fl =
(FrameLayout)LayoutInflater.from(getBaseContext()).inflate(R.layout.framelayoutstyle,
l1, false);
TextView textoEscrito;
textoEscrito =
(TextView)LayoutInflater.from(getBaseContext()).inflate(R.layout.textviewstyle,
fl, false);
textoEscrito.setText(array[i][0]);
final String texto =
textoEscrito.getText().toString();
final String textoFalar = array[i][2];
ImageButton btn;
btn =
(ImageButton)LayoutInflater.from(getBaseContext()).inflate(R.layout.imagebuttonstyle,
fl, false);
btn.setImageResource(this.getResources().getIdentifier("drawable/" +
array[i][1], null, this.getPackageName()));
btn.setOnClickListener(new Button.OnClickListener(){
public void onClick (View v){
Toast.makeText(getBaseContext(), texto,
Toast.LENGTH_SHORT).show();
//*******************************
//HERE IS MY PROBLEM!!!
//*******************************
tts.speak(txtFl, TextToSpeech.QUEUE_ADD, null);
//*******************************
//WHEN I TRY TO RUN THE ABOVE IT GIVES A
NULLPOINTEREXCEPTION!!!
//*******************************
}
});
fl.addView(btn);
fl.addView(textoEscrito);
l1.addView(fl);
}
lgeral.addView(l1);
}
setContentView(lgeral);
}
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
tts = new TextToSpeech(this, this);
}
else {
// missing data, install it
Intent installIntent = new Intent();
installIntent.setAction(TextToSpeech.Engine.ACTION_INSTALL_TTS_DATA);
startActivity(installIntent);
}
}
}
@Override
public void onInit(int status) {
if (status == TextToSpeech.SUCCESS) {
}
else if (status == TextToSpeech.ERROR) {
}
}
@Override
public void onDestroy() {
if (tts != null) {
tts.stop();
tts.shutdown();
}
super.onDestroy();
}
}
By the way... the method Toast.makeText(getBaseContext(), texto,
Toast.LENGTH_SHORT).show(); works fine. I believe that's because the Toast
is a static class.
So, maybe the solution is to create a static class with the method to
speak? Ideas? How can I do it?
