I working on a speech recognition on Android Studio. How can I let the output of my spoken input be in the second activity? This is what I tried so far:
public class MainActivity extends AppCompatActivity {
private TextView voiceInput;
private ImageView speakButton;
private final int REQ_CODE_SPEECH_INPUT = 100;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
voiceInput = (TextView) findViewById(R.id.voiceInput);
speakButton = (ImageView) findViewById(R.id.btnSpeak);
speakButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
askSpeechInput();
}
});
}
// Showing google speech input dialog
private void askSpeechInput() {
Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,
RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE, Locale.getDefault());
intent.putExtra(RecognizerIntent.EXTRA_PROMPT,
"Hi speak something");
try {
startActivityForResult(intent, REQ_CODE_SPEECH_INPUT);
} catch (ActivityNotFoundException a) {
}
}
// Receiving speech input
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode) {
case REQ_CODE_SPEECH_INPUT: {
if (resultCode == RESULT_OK && null != data) {
ArrayList<String> result = data.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
voiceInput.setText(result.get(0));
}
break;
}
}
}
}
This part is for the output responsible:
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode) {
case REQ_CODE_SPEECH_INPUT: {
if (resultCode == RESULT_OK && null != data) {
ArrayList<String> result = data.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
voiceInput.setText(result.get(0));
}
break;
}
}
}
If you need more information please let me know and sorry for the dumb question, I think the solution is very easy but I couldn't fine them!
I don't know exactly if I got you right, but you can do something like this:
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode) {
case REQ_CODE_SPEECH_INPUT: {
if (resultCode == RESULT_OK && null != data) {
ArrayList<String> result = data.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
Intent intent = new Intent(this,SecondActivity.class);
intent.putExtra("KEY",result);
startActivity(intent);
}
break;
}
}
and recover data in onCreate() of SecondActivity:
onCreate(){
...
ArrayList<String> result = (ArrayList<String>) getIntent().getSerializableExtra("KEY);
}

Issue:
I have a Listview in Mainactivity. Each row of listview has two buttons say SET and RUN.
Pressing SET will take you to SET activity and if the user clicks save button in SET Activity, I need to disable the SET button in the corresponding row position of the listview in mainactivity.
So Far Done:
For that I have a refresh function on a onclicklistener to requery the list with updated values. How to call that refresh function without keypress in the Mainactivity or is there any other way?
Activity MAIN :
viewHolder.ButtonSET.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
String title = v.getTag().toString();
if (title.equals("SET")) {
if (Integer.parseInt((String) viewHolder.TDNQTY.getText()) > 0) {
if(scanoverornot(pos)<=0) {
Intent s = new Intent(DN.this, SETActivity.class);
s.putExtra("position", pos);
s.putExtra("mode", "SET");
try{
startActivityForResult(s, saverequestcode);
// getContext().startActivity(s);
}
catch(Exception e){
Toast.makeText(getContext(),""+e,Toast.LENGTH_LONG).show();
}
}
}
}
}
});
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (data == null)
return;
switch (requestCode) {
case saverequestcode:
if (resultCode == RESULT_OK) {
String SItem= data.getStringExtra("SItem");
int SPos= data.getIntExtra("SPos", 0);
saved = 700;
Toast.makeText(getApplicationContext(), ""+ SItem+ SPos, Toast.LENGTH_LONG).show();
//btnvalidate.performClick();
}
}
}
Activity SET :
Intent sav = new Intent();
sav.putExtra("SItem", String.valueOf(itemno));
sav.putExtra("SPos", String.valueOf(pos));
setResult(RESULT_OK, sav);
finish();
You can use startActivityForResult to nail this purpose:
startActivityForResult(new Intent(this, DestinationActivity.class), MY_RESULT);
And then in your MainActivity:
public int MY_RESULT = 10;
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == MY_RESULT) {
if (resultCode == Activity.RESULT_OK) {
//refresh the list according to your logic
}
}
}
Don't forget to call setResult(Activity.RESULT_OK); when user clicks save button.
saveButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
setResult(Activity.RESULT_OK);
}
});
Issue Lines:
Have to add super.onActivityResult(requestCode, resultCode, data);
Removed switch case and used if condition for requestCode check
Solution:
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (data == null)
return;
if (requestCode == saverequestcode) {
if (resultCode == Activity.RESULT_OK) {
String SItem = data.getStringExtra("SItem");
String SPos = data.getStringExtra("SPos");
Toast.makeText(getApplicationContext(), "Item :" + SItem + "Position :" + SPos, Toast.LENGTH_LONG).show();
}
if (resultCode == Activity.RESULT_CANCELED) {
//Any methods
}
}
else if (requestCode == importrequestcode){
}
}
Activity SET :
Intent sav = new Intent();
sav.putExtra("SItem", String.valueOf(itemno));
sav.putExtra("SPos", String.valueOf(pos));
setResult(Activity.RESULT_OK,sav);
finish();
I have an activity that once a ToggleButton is clicked, it starts another activity as follows:
Intent intent = new Intent(ChatActivity.this, BBActivity.class);
startActivityForResult(intent,1);
In that second activity it performs few calculations and then:
confirmedData.putExtra( "confirmedB", (Serializable) bSelected );
confirmedData.putExtra( "dateInMillis",DateInMillis );
setResult(ChatActivity.RESULT_OK,confirmedData);
Then, I use the following to get the results in my first activity:
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == 1) {
if(resultCode == ChatActivity.RESULT_OK){
ArrayList<DiscoverB> confirmedB = (ArrayList<DiscoverB>)data.getSerializableExtra("confirmedB");
Long DateInMillis = data.getLongExtra( "dateInMillis", System.currentTimeMillis());
Log.d("ERROR", "error");
}
if (resultCode == ChatActivity.RESULT_CANCELED) {
}
}
}
Now, I had like to use confirmedB Once a button in my activity is clicked.
How can I pass the values from onActivityResult to my ClickListener?
ChatAdapter.OnConfirmClickListener confirmListener = new ChatAdapter.OnConfirmClickListener(){
#Override
public void onClick(Button confirmB) {
???myarraylist = onActivityResult(requestCode, resultCode, data)???
HERE I NEED MY confirmedB
}
};
Thank you
In your first activity, declare a variable
ArrayList<DiscoverB> confirmedB;
In OnActivityResult, you can initialize confirmedB
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == 1) {
if(resultCode == ChatActivity.RESULT_OK){
confirmedB = (ArrayList<DiscoverB>)data.getSerializableExtra("confirmedB");
Long DateInMillis = data.getLongExtra( "dateInMillis", System.currentTimeMillis());
Log.d("ERROR", "error");
}
if (resultCode == ChatActivity.RESULT_CANCELED) {
}
}
}
You can use it now in your clickListener,
ChatAdapter.OnConfirmClickListener confirmListener = new ChatAdapter.OnConfirmClickListener(){
#Override
public void onClick(Button confirmB) {
???myarraylist = onActivityResult(requestCode, resultCode, data)???
here you can use confirmedB
}
};
I have the next activities:
Activity1
//declare
private static final int SAVE_DATA_FROM_ACTIVITY = 203;
//........... not important code
//button to open second Activity
public void btn_openSecondActivity(View view)
{
Intent intent = new Intent(Activity2.this, Activity1.class);
startActivityForResult(intent, SAVE_DATA_FROM_ACTIVITY);
}
}
protected void onActivityResult (int requestCode, int resultCode, Intent data)
{
if (requestCode == SAVE_DATA_FROM_activity)
{
name= data.getStringExtra("Name");
}
}
//....... not important code
Activity2
On Second Activity I have two buttons:
Cancel
Save
//............
//declare
private static final int OK_RESULT_CODE = 1;
//Cancel button
public void btn_cancel(View view)
{
finish();
}
//Save button
public void btn_save (View view)
{
Intent intent = new Intent();
intent.putExtra("Name",et_name.getText().toString());
setResult(OK_RESULT_CODE, intent);
finish();
}
PROBLEM
When I click Save button all works perfect, but the problem it's when I click Cancel button, then it's reports an error:
Failure delivering result ResultInfo{who=null, request=203, result=0, data=null} to activity {com.example.alvaro.project/com.alvaro.project.Activity1}: java.lang.NullPointerException
I understand the problem, when I cancel is not the same result code but i don't know how I can solve it
Any suggestions?
You have issue in onActivityResult method. You don't check result.
Change your condition from :
if (requestCode == SAVE_DATA_FROM_activity)
to:
if (resultCode == OK_RESULT_CODE && requestCode == SAVE_DATA_FROM_activity)
Change this
if (requestCode == SAVE_DATA_FROM_activity)
{
name= data.getStringExtra("Name");
}
into
if (requestCode == SAVE_DATA_FROM_activity&&resultCode==RESULT_OK)
{
name= data.getStringExtra("Name");
}
and
Your cancel method is like
public void btn_cancel(View view)
{
setResult(RESULT_CANCELED);
finish();
}
And instead of OK_RESULT_CODE use Android default ok like Activity.RESULT_OK
Check if you manage to set the result
protected void onActivityResult (int requestCode, int resultCode, Intent data)
{
if (requestCode == SAVE_DATA_FROM_activity && resultCode = Activity2.OK_RESULT_CODE)
{
name= data.getStringExtra("Name");
} else {
//probably btn_cancel pressed
}
}
check resultCode in onActivityResult
protected void onActivityResult (int requestCode, int resultCode, Intent data)
{
if (resultCode == 1/*OK_RESULT_CODE from Second Activity */ && requestCode == SAVE_DATA_FROM_activity)
{
name= data.getStringExtra("Name");
}
}
Activity1
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == SAVE_DATA_FROM_activity) {
if (resultCode == Activity.RESULT_OK) {
name = data.getStringExtra("Name");
} else if (resultCode == Activity.RESULT_CANCELED){
// TODO something
}
}
}
Activity2
delete field OK_RESULT_CODE
//Cancel button
public void btn_cancel(View view) {
setResult(Activity.RESULT_CANCELED, new Intent());
finish();
}
//Save button
public void btn_save(View view) {
Intent intent = new Intent();
intent.putExtra("Name", et_name.getText().toString());
setResult(Activity.RESULT_OK, intent);
finish();
}
I am developing an Android application of speech recognition for non-dictionary words. I want to remove the dictionary and do it for any word.
For example If I pronounce word "pini", my current application get it as "beanie". I want the word to recognize as it is pronounced.
My code:
public void onClick(View v) {
// TODO Auto-generated method stub
switch (v.getId()) {
case R.id.btnSpeak:
promptSpeechInput();
break;}
}
#Override
// act on result of TTS data check
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == MY_DATA_CHECK_CODE) {
if (resultCode == TextToSpeech.Engine.CHECK_VOICE_DATA_PASS) {
myTTS = new TextToSpeech(this, this);
} else {
Intent installTTSIntent = new Intent();
installTTSIntent
.setAction(TextToSpeech.Engine.ACTION_INSTALL_TTS_DATA);
startActivity(installTTSIntent);
}
}
// Receiving speech input
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode) {
case REQ_CODE_SPEECH_INPUT: {
if (resultCode == RESULT_OK && null != data) {
ArrayList<String> result = data
.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
txtSpeechInput.setText(result.get(0));
}
break;
}
}
}
#Override
// act on result of TTS data check
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == MY_DATA_CHECK_CODE) {
if (resultCode == TextToSpeech.Engine.CHECK_VOICE_DATA_PASS) {
myTTS = new TextToSpeech(this, this);
} else {
Intent installTTSIntent = new Intent();
installTTSIntent
.setAction(TextToSpeech.Engine.ACTION_INSTALL_TTS_DATA);
startActivity(installTTSIntent);
}
}
// Receiving speech input
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode) {
case REQ_CODE_SPEECH_INPUT: {
if (resultCode == RESULT_OK && null != data) {
ArrayList<String> result = data
.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
txtSpeechInput.setText(result.get(0));
}
break;
}
}
}
public void speakWords(String speech) {
myTTS.speak(speech, TextToSpeech.QUEUE_FLUSH, null);
}
/**

Any help would be appreciated.
Thanks.
I have this code:
/**
* Showing google speech input dialog
*/
private void promptSpeechInput() {
Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,
RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE, Locale.getDefault());
intent.putExtra(RecognizerIntent.EXTRA_PROMPT,
getString(R.string.speech_prompt));
try {
startActivityForResult(intent, REQ_CODE_SPEECH_INPUT);
} catch (ActivityNotFoundException a) {
Toast.makeText(getActivity().getApplicationContext(),
getString(R.string.speech_not_supported),
Toast.LENGTH_SHORT).show();
}
and i'm doing call:
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
promptSpeechInput();
}
});
but i never seen activity with voice recording. Immediately there is a call:
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode) {
case REQ_CODE_SPEECH_INPUT: {
if (resultCode == Activity.RESULT_OK && null != data) {
ArrayList<String> result = data
.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
mAdapter.addTag(result.get(0));
//txtSpeechInput.setText(result.get(0));
}
break;
}
}
}
with resultCode == Activity.RESULT_CANCEL
I have permission to Internet.
Thank you.
