What is the code about:
With my code I can open a mic, speak into it and see the output.
Present Situation
Right now if I speak into the mic, I see the output and jump directly in other activity.
Requirement
I want take the output in the activity but before I text to much I show you the code.
Mainactivity.java
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, "Sprechen Sie was ein");
//tent.putStringArrayListExtra("result",resultat);
try {
startActivityForResult(intent, REQ_CODE_SPEECH_INPUT);
} catch (ActivityNotFoundException a) {
}
}
#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) {
Intent intent=new Intent(this,Zweites.class);
ArrayList<String> result = data.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
voiceInput.setText(result.get(0));
intent.putStringArrayListExtra("resultat",result);
//ActivityZweites wird gestartet
startActivity(intent);
}
break;
}
} }} <br>
In that I got the following problem:
if (resultCode == RESULT_OK && null != data) {
ArrayList<String> result = data.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
//Ausgabe in andere Activity
voiceInput.setText(result.get(0));
Intent intent=new Intent(this,Zweites.class);
intent.putStringArrayListExtra("resultat",result);
//ActivityZweites wird gestartet
startActivity(intent);
}
break;
}
There it outputs the spoken input:
voiceInput.setText(result.get(0));
And afterwards it jumps into the activity.
How can I get this output in the activity without first display the output and jump in another activity?
I tried some things but don´t come to a solution how to fix this problem.
Do you guys got some ideas?
Kind regards
If you simply want to pass the same text to your intent that you're displaying in your TextView, exchange
intent.putStringArrayListExtra("resultat",result);
with
intent.putExtra("resultat", result.get(0));
Then, in your Zweites activity, you can get the string like so:
Intent intent = getIntent();
String text = intent.getStringExtra("resultat");

I'm trying to include a microphone button where user can click it and it can prompt a voice input from the user. Then the voice input will be converted into String and shown in a TextView in my android app. For now, the voice input can be prompted but the converted String will not be shown in my TextView and there are no crashes or logcat. Just that it wont be shown in my TextView. All this is happening in a class which extends Fragment.
Below is the code for my microphone button :-
//Button to activate voice recognition
microphonebutton = (ImageButton) view.findViewById(R.id.button_microphone);
microphonebutton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
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());
if (intent.resolveActivity(getActivity().getPackageManager()) != null) {
startActivityForResult(intent, 10);
} else {
Toast.makeText(getActivity().getApplicationContext(), "Your device does not support speech input !",Toast.LENGTH_SHORT).show();
}
}
});
The method onActivityResult:-
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch (resultCode) {
case 10:
if (resultCode == Activity.RESULT_OK && data != null) {
ArrayList<String> result = data.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
texttotranslate.setText("");
texttotranslate.setText(result.get(0), TextView.BufferType.EDITABLE);
}
break;
}
}
I got these codes from a tutorial on youtube and it seemed to be working fine for the person who was presenting the tutorial.
You have a typo in the method onActivityResult. In the switch you are chechking the resultCode twice. First you should check the requestCode. The requestCode is the code which you defined in startActivityForResult, in your case 10.
As i am developing an android app and wants to convert speech into text, i am using built-in Google speech input activity to convert voice into text. I need past information but it continuously get cleared i got only current response. How need to handle same as google voice keyboard. As i talk it included to current String instep of clear.
MainActivity .java
public class MainActivity extends AppCompatActivity
{
private EditText txtSpeechInput;
private ImageButton btnSpeak;
private final int REQ_CODE_SPEECH_INPUT = 100;
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
txtSpeechInput = findViewById(R.id.txtSpeechInput);
btnSpeak = (ImageButton) findViewById(R.id.btnSpeak);
btnSpeak.setOnClickListener(new View.OnClickListener()
{
#Override
public void onClick(View v)
{
promptSpeechInput();
}
});
private void promptSpeechInput()
{
Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);

RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);

try
{
startActivityForResult(intent, REQ_CODE_SPEECH_INPUT);
}
catch (ActivityNotFoundException a)

Toast.LENGTH_SHORT).show();
}
}

switch (requestCode)
{
case REQ_CODE_SPEECH_INPUT:

if (resultCode == RESULT_OK && null != data)

txtSpeechInput.setText(result.get(0));
}
break;
}
}
}
If you only want to save one previously detected String, for this to achieve, you need to make a global String variable and store the value in that variable from results list.(Save the same String as you are setting on text view). But if you want to save all the strings, you need to make global String Arraylist and add all those string in that array list. Below is the code for that.
private EditText txtSpeechInput;
private ImageButton btnSpeak;
private final int REQ_CODE_SPEECH_INPUT = 100;
private List<String> previousStringList;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
previousStringList = new ArrayList<>();
txtSpeechInput = findViewById(R.id.txtSpeechInput);
btnSpeak = (ImageButton) findViewById(R.id.btnSpeak);
btnSpeak.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
promptSpeechInput();
}
});
}
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));
intent.putExtra(RecognizerIntent.EXTRA_SPEECH_INPUT_MINIMUM_LENGTH_MILLIS, 20000000);
try {
startActivityForResult(intent, REQ_CODE_SPEECH_INPUT);
} catch (ActivityNotFoundException a) {
Toast.makeText(getApplicationContext(),
getString(R.string.speech_not_supported),
Toast.LENGTH_SHORT).show();
}
}
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) {
final ArrayList<String> result = data
.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
txtSpeechInput.setText(result.get(0));
if (result.get(0) != null) {
previousStringList.add(result.get(0));
}
}
break;
}
}
}
Hope that helps you.If you don't understand anything feel free to ask. If you don't want to save same String twice(already saved string), just replace below conditional line of code..
if (result.get(0) != null && !previousStringList.contains(result.get(0))) {
previousStringList.add(result.get(0));
}
The words get stored in Arraylists.
You can see an example of the implementation here, it works fine. The app stores the words, and then also performs the action requested.

case REQ_CODE_SPEECH_INPUT: {
if (resultCode == RESULT_OK && null != data) {
final ArrayList<String> result = data
.getStringArrayListExtra( RecognizerIntent.EXTRA_RESULTS );
//this is the real problem.
txtSpeechInput.setText( previous + " " + result.get( 0 ) );
previous = txtSpeechInput.getText().toString();
txtSpeechInput.setText( previous );
}
break;

I am trying to hide the speech recogniser dialog that shows up saying "speak now" and written google as the title ,whenever i call it for passing some voice command. I don't want it to show up. Instead I want it to work in teh background so that the user cannot see it. What should be the correct way to do it?
public void getSpeechInput(View view) {
getWindow().getDecorView().setBackgroundResource(android.R.color.transparent);
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());
if (intent.resolveActivity(getPackageManager()) != null) {
startActivityForResult(intent, 10);
} else {
Toast.makeText(this, "Your Device Don't Support Speech Input", Toast.LENGTH_SHORT).show();
}
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode) {
case 10:
if (resultCode == RESULT_OK && data != null) {
ArrayList<String> result = data.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
txvResult.setText(result.get(0));
String str = txvResult.getText().toString();
if(str.equals("lights on")){
Toast.makeText(MainActivity.this,
"matched", Toast.LENGTH_LONG).show();
count[0]=1;
turnOnFlash();
}
else if(str.equals("lights off")){
Toast.makeText(MainActivity.this,
"didnt", Toast.LENGTH_LONG).show();
count[0]=0;
turnOffFlash();
}
}
break;
}
}
I tried using this but it didn't work:-
getWindow().getDecorView().setBackgroundResource(android.R.color.transparent);
Try this. This listener catches the events and you can process them accordingly.
SpeechRecognizer recognizer = SpeechRecognizer.createSpeechRecognizer(this);
recognizer.setRecognitionListener(new RecognitionListener()
{
//Do whatever you want
});
So I am trying to implement calling the same activity twice, I understand there will be better ways to do this but right now I just want 2 separate data recordings. When I try to run this code, the Diastolic BP gets read in first which is unintentional. Can someone explain why this is happening please. Thank you.
Intent i = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
//The following is required when ^^^ this is used
i.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
i.putExtra(RecognizerIntent.EXTRA_PROMPT, "Please Read your Systolic Blood Pressure Value");
startActivityForResult(i, SYSTOLIC_CHECK);
//A different request code is required per activity called
Intent j = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
j.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
j.putExtra(RecognizerIntent.EXTRA_PROMPT, "Please Read your Diastolic Blood Pressure Value");
startActivityForResult(j, DIASTOLIC_CHECK);
...
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == TAKE_PICTURE_REQUEST && resultCode == RESULT_OK) {
String thumbnailPath = data.getStringExtra(Intents.EXTRA_THUMBNAIL_FILE_PATH);
String picturePath = data.getStringExtra(Intents.EXTRA_PICTURE_FILE_PATH);
processPictureWhenReady(picturePath);
// TODO: Show the thumbnail to the user while the full picture is being
// processed.
}
else if ((requestCode == SYSTOLIC_CHECK) && resultCode == RESULT_OK) {
results = data.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
String spokenText = results.get(0);
System.out.println("Systolic BP: " + spokenText);
//OutputStreamWriter out = new OutputStreamWriter(openFileOutput(STORETEXT, 0));
}
else if ((requestCode == DIASTOLIC_CHECK) && resultCode == RESULT_OK) {
results = data.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
String spokenText = results.get(0);
System.out.println("Diastolic BP: " + spokenText);
//OutputStreamWriter out = new OutputStreamWriter(openFileOutput(STORETEXT, 0));
}
super.onActivityResult(requestCode, resultCode, data);
}
The API simply doesn't work that way - you can't queue up the launch multiple activities as you are trying to do.
The normal way to do this is to launch the first Activity with startActivityForResult, and when the first activity returns, launch the second one.
If I'm not mistaken, since you call your Diastolic activity as last, this is laid over you systolic activity.
So you Diastolic Activity will be the one the user interacts with first.
I just want to point out that what #GreyBeardedGeek said is true.
It probably would be better if you just start you systolic activity, then, when you receive the result, start you Diastolic Activity (in OnActivityResult).
This will prevent issues with your activities not starting in the order you wanted.
EDIT
Your code would look something like this then
...else if ((requestCode == SYSTOLIC_CHECK) && resultCode == RESULT_OK) {
results = data.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
String spokenText = results.get(0);
System.out.println("Systolic BP: " + spokenText);
//OutputStreamWriter out = new OutputStreamWriter(openFileOutput(STORETEXT, 0));
//call second activity
Intent j = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
j.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
j.putExtra(RecognizerIntent.EXTRA_PROMPT, "Please Read your Diastolic Blood Pressure Value");
startActivityForResult(j, DIASTOLIC_CHECK);
} ...
EDIT
Your activity could look like this.
public class VoiceActivity extends ActionBarActivity {
private String systole;
private String diastole;
private Button btnGetVoiceInput;
private final int SYSTOLIC_CHECK=1, DIASTOLIC_CHECK=2;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
btnGetVoiceInput = (Button) findViewById(R.id.btnVoiceInput);
btnGetVoiceInput.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent i = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
//The following is required when ^^^ this is used
i.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
i.putExtra(RecognizerIntent.EXTRA_PROMPT, "Please Read your Systolic Blood Pressure Value");
startActivityForResult(i, SYSTOLIC_CHECK);
}
});
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
switch (requestCode){
case SYSTOLIC_CHECK: {
if(resultCode == RESULT_OK) {
ArrayList<String> results = data.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
systole = results.get(0);
System.out.println("Systolic BP: " + systole);
Intent j = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
j.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
j.putExtra(RecognizerIntent.EXTRA_PROMPT, "Please Read your Diastolic Blood Pressure Value");
startActivityForResult(j, DIASTOLIC_CHECK);
}
break;
}
case DIASTOLIC_CHECK: {
if(resultCode == RESULT_OK) {
ArrayList<String> results = data.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
diastole = results.get(0);
Log.v("VoiceInput", "Diastolic BP: " + diastole);
doSomething();
}
break;
}
}
}
private void doSomething() {
//do what you want with both readings here
String bloodpressure = systole + " / " + diastole;
Log.v("Bloodpressure", bloodpressure);
}
}
After getting the 2 readings, you can do something with them.
This does still need some error handling, but I haven't used the voice input yet, so I don't know what values it returns/can return.
as the title says, I'm trying to scan 1D barcodes, so far I have thet following code:
public class MainActivity extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
public void test(View view){
Intent intent = new Intent("com.google.zxing.client.android.SCAN");
intent.putExtra("SCAN_MODE", "1D_CODE_MODE");
startActivityForResult(intent, 0);
}
public void onActivityResult(int requestCode, int resultCode, Intent intent) {
switch (requestCode) {
case IntentIntegrator.REQUEST_CODE:
if (resultCode == Activity.RESULT_OK) {
IntentResult intentResult =
IntentIntegrator.parseActivityResult(requestCode, resultCode, intent);
if (intentResult != null) {
String contents = intentResult.getContents();
String format = intentResult.getFormatName();
TextView uno = (TextView) findViewById(R.id.textView1);
uno.setText(contents);
Toast.makeText(this, "Numero: " + contents, Toast.LENGTH_LONG).show();
Log.d("SEARCH_EAN", "OK, EAN: " + contents + ", FORMAT: " + format);
} else {
Log.e("SEARCH_EAN", "IntentResult je NULL!");
}
} else if (resultCode == Activity.RESULT_CANCELED) {
Log.e("SEARCH_EAN", "CANCEL");
}
}
}
}
And of course, I have both IntentResult and IntentIntegrator added to the project.
So, the scanner is beeing called correctly when a button is pressed and it seems to scan the code perfectly (it says "Text found" after it scans it), but it seems that the onActivityResult is not called, since the TextView is not beeing updated and the Toast is not appearing.
Any idea on what the mistake could be?
Thanks in advance!
Your first mistake is not using IntentIntegrator.initiateScan(), replacing it with your own hand-rolled call to startActivityForResult().
Your second mistake is in assuming that IntentIntegrator.REQUEST_CODE is 0. It is not.
Hence, with your current code, you are sending out a request with request code of 0, which is coming back to onActivityResult() with request code of 0, which you are ignoring, because you are only looking for IntentIntegrator.REQUEST_CODE.
Simply replace the body of your test() method with a call to initiateScan(), and you should be in better shape. Here is a sample project that demonstrates the use of IntentIntegrator.
I resolve your same problem so.
public class MainActivity extends Activity {
private TextView tvStatus, tvResult;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
this.tvStatus = (TextView) findViewById(R.id.tvStatus);
this.tvResult = (TextView) findViewById(R.id.tvResult);
Button scanBtn = (Button) findViewById(R.id.btnScan);
scanBtn.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
try {
Intent intent = new Intent(
"com.google.zxing.client.android.SCAN");
intent.putExtra("SCAN_FORMATS", "QR_CODE_MODE");
startActivityForResult(intent,
IntentIntegrator.REQUEST_CODE);
} catch (Exception e) {
Log.e("BARCODE_ERROR", e.getMessage());
}
}
});
}
public void onActivityResult(int requestCode, int resultCode, Intent intent) {
IntentResult scanResult = IntentIntegrator.parseActivityResult(
requestCode, resultCode, intent);
if (scanResult != null) {
this.tvStatus.setText(scanResult.getContents());
this.tvResult.setText(scanResult.getFormatName());
}
}
}
The onActivityResault function must be overridden. just add an #Override before the function declaration and it will be solved.
