I make speech recognition application. But i have a problem. How can i make an transition from letter category menu to speech recognition menu, but don' add new class or new layout. Example. When i click A button, it will get A menu with speech recognition menu and so on. Sorry, i'm new in Android studio.
Here is the code for Speech Recognition
public class MainGame extends AppCompatActivity {
private TextView jawabanTxt;
private String textA;
TextView textView;
SpeechRecognizer mSpeechRecognizer;
Intent mSpeechRecognizerIntent;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main_game_act);
jawabanTxt = (TextView) findViewById(R.id.jawabanTxt);
textView = (TextView) findViewById(R.id.textView);
}
public void getSpeechInput(View view){
Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,Locale.getDefault());
if(intent.resolveActivity(getPackageManager())!=null) {
startActivityForResult(intent, 10);
} else {
Toast.makeText(this, "Perangkat anda tidak mendukung", Toast.LENGTH_SHORT).show();
}
}
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);
jawabanTxt.setText(result.get(0));
}
break;
}
}
}
And here is the code for the category
public class HurufActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
final TextView ATxt;
ImageButton aBtn;
super.onCreate(savedInstanceState);
setContentView(R.layout.huruf_activity);
ATxt = (TextView) findViewById(R.id.aTxt);
aBtn = (ImageButton) findViewById(R.id.aBtn);
aBtn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
try {
TextView textA = (TextView) ATxt.getText();
if (textA == ATxt) {
Intent intent = new Intent(HurufActivity.this, MainGame.class);
startActivity(intent);
}
} catch (Exception e) {
e.printStackTrace();
}
}
});
}
}
From this:
To This:
Thank You
Something wrong is here:
try {
TextView textA = (TextView) ATxt.getText();
if (textA == ATxt) {
Intent intent = new Intent(HurufActivity.this, MainGame.class);
startActivity(intent);
}
} catch (Exception e) {
e.printStackTrace();
}
I think, that this try - catch block is unnecessary and this (TextView) ATxt.getText(); will not work.
Just do something like this:
aBtn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Intent intent = new Intent(HurufActivity.this, MainGame.class);
startActivity(intent);
}
});

Will appriciate any help
public class SpeakingActivity extends AppCompatActivity {
private static final int REQUEST_CODE_SPEECH_INPUT = 1000;
TextView mTextView;
TextView input;
ImageButton mImageButton;
Button button;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.speakingfromhome);
button = findViewById(R.id.nextSpeaking);
mTextView = findViewById(R.id.output);
mImageButton = findViewById(R.id.image);
input = findViewById(R.id.input);
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
changeQuestions();
mTextView.setTextColor(Color.BLACK);
}
});
mImageButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
speak();
checkIfCorrect();
}
});
}
private void checkIfCorrect() {
if (input.toString().equals(mTextView.toString()))
mTextView.setTextColor(Color.GREEN);
else
mTextView.setTextColor(Color.RED);
}
private void changeQuestions() {
input.setText("基辅");
}
private void speak() {
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.CHINA.toString());
try {
startActivityForResult(intent, REQUEST_CODE_SPEECH_INPUT);
} catch (Exception ex) {
Toast.makeText(this, "" + ex.getMessage(), Toast.LENGTH_SHORT).show();
}
}
#Override
protected void onActivityResult(int requestCode, int resultCode, #Nullable Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode) {
case REQUEST_CODE_SPEECH_INPUT: {
if (resultCode == RESULT_OK && null != data) {
ArrayList<String> result = data.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
mTextView.setText(result.get(0));
}
break;
}
}
}
}
The function checkIfCorrect() is the problem
Change it to:
input.toString() -> input.getText()
mTextView.toString() -> mTextView.getText()
Like:
input.getText().equals(mTextView.getText())
with getText() get the text of the TextView, doint input.toString() convert the object TextView to String
your checkIfCorrect function must look like:
private void checkIfCorrect() {
if (input.getText().equals(mTextView.getText()))
mTextView.setTextColor(Color.GREEN);
else
mTextView.setTextColor(Color.RED);
}
A better way:
private void checkIfCorrect() {
mTextView.setTextColor((input.getText().equals(mTextView.getText())) ? Color.GREEN : Color.RED )
}
I tried using a "speech to text" feature in my app.
it opens up the recording window/ dialog or whatever but the text doesn't show.
this is the code:
public void onTalk(View v){
promptSpeechInput();
}
public void promptSpeechInput()
{
Intent i=new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
i.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
i.putExtra(RecognizerIntent.EXTRA_LANGUAGE, Locale.getDefault());
i.putExtra(RecognizerIntent.EXTRA_PROMPT,"say something");
try{
startActivityForResult(i, 50);
}
catch(ActivityNotFoundException e){
Toast.makeText(this,"sorry your device doesnt support speech language",Toast.LENGTH_LONG).show();
}
}
then there's the onResult part:
public void onActivityResult(int request_code, int result_code, Intent i){
super.onActivityResult(request_code,result_code,i);
if (request_code==RESULT_OK)
if(i!=null) {
EditText locationTS = (EditText) findViewById (R.id.locationET);
ArrayList<String> result = i.getStringArrayListExtra((RecognizerIntent.EXTRA_RESULTS));
locationTS.setText(result.get(0));
}
}
locationTS is an EditText, and it does not show any text after i talk.
This worked in my case:
I had a separate Helper class as:
public class SpeechRecognitionHelper {
private static final int VOICE_RECOGNITION_REQUEST_CODE=101;
public static void run(Activity activity){
if(isSpeechRecognitionActivityPresent(activity)){
startRecognition(activity);
}
else {
Toast.makeText(activity,"You must install Google Voice Search",Toast.LENGTH_LONG).show();
installGoogleVoiceSearch(activity);
}
}
private static boolean isSpeechRecognitionActivityPresent(Activity activity){
try {
PackageManager packageManager = activity.getPackageManager();
List activities = packageManager.queryIntentActivities(new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH),0);
if (activities.size()!=0){
return true;
}
}
catch (Exception e){
}
return false;
}
public static void startRecognition(Activity activity){
Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
intent.putExtra(RecognizerIntent.EXTRA_PROMPT,"Say Something");
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
intent.putExtra(RecognizerIntent.EXTRA_MAX_RESULTS,1);
activity.startActivityForResult(intent,VOICE_RECOGNITION_REQUEST_CODE);
}
private static void installGoogleVoiceSearch(final Activity activity){
Dialog dialog = new AlertDialog.Builder(activity)
.setMessage("For recognition Install Google Voice Search")
.setTitle("Install voice search?")
.setPositiveButton("Install", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialogInterface, int i) {
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("market://details?id=com.google.android.voicesearch"));
intent.setFlags(Intent.FLAG_ACTIVITY_NO_HISTORY | Intent.FLAG_ACTIVITY_CLEAR_WHEN_TASK_RESET);
activity.startActivity(intent);
}
})
.setNegativeButton("Cancel", null)
.create();
dialog.show();
}
}
Then in the MainActivity:
public class MainActivity extends AppCompatActivity implements View.OnClickListener{
private static final int VOICE_RECOGNITION_REQUEST_CODE=101;
private static final int CAMERA_REQUEST=201;
private Button buttonVoiceCommand;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
buttonVoiceCommand = (Button)findViewById(R.id.buttonVoiceCommand);
buttonVoiceCommand.setOnClickListener(this);
}
#Override
public void onClick(View view) {
int id = view.getId();
if (id == R.id.buttonVoiceCommand){
run(MainActivity.this);
}
}
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data){
super.onActivityResult(requestCode,resultCode,data);
if (requestCode == VOICE_RECOGNITION_REQUEST_CODE && resultCode == RESULT_OK) {
ArrayList<String> matches = data.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
if(matches.size()>0){
if(matches.get(0).indexOf("camera")>0){
Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent,CAMERA_REQUEST);
}
else {
Toast.makeText(this,matches.get(0),Toast.LENGTH_LONG).show();
}
}
}
if (requestCode == CAMERA_REQUEST && resultCode == RESULT_OK) {
//Perform whatever you want to do (-.-)
Toast.makeText(this,"Camera Working",Toast.LENGTH_LONG).show();
}
}
}
I Toast the content of matches.get(0) You just have to set it in an edit text
I managed to start a conference call cut it closes right after I start it with HUNG_UP cause and I got this in my log:
11-03 17:28:08.940: E/sinch-android-rtc(19101): peermediaconnection: virtual void rebrtc::SetSDPObserver::OnFailure(const string&)Failed to set remote answer sdp: Offer and answer descriptions m-lines are not matching. Rejecting answer.
11-03 17:28:08.940: E/sinch-android-rtc(19101): mxp: Failed to set remote answer sdp: Offer and answer descriptions m-lines are not matching. Rejecting answer.
can anybody help me solve this please?
Edit:
my scenario is when a user clicks the call button I ask him if he wants to start a new call or join an already created one.
I managed to make my code from this question (Sinch conference call error) work as my GroupService class had some bugs.
I start my call like this:
Intent intent1 = new Intent(CreateGroupCallActivity.this,SinchClientService.class);
intent1.setAction(SinchClientService.ACTION_GROUP_CALL);
String id = String.valueOf(uid) + "-" + call_id.getText().toString();
intent1.putExtra(SinchClientService.INTENT_EXTRA_ID,id);
startService(intent1);
and in my SinchClientService:
if(intent.getAction().equals(ACTION_GROUP_CALL))
{
String id = intent.getStringExtra(INTENT_EXTRA_ID);
if(id != null)
groupCall(id);
}
public void groupCall(String id) {
if (mCallClient != null) {
Call call = mCallClient.callConference(id);
CurrentCall.currentCall = call;
Log.d("call", "entered");
Intent intent = new Intent(this, GroupCallService.class);
startService(intent);
}
}
nd here is my GroupCallService

I am using the ZXING QR Code Reader. It is working fine. Detecting codes etc but it does not shows any detection progress(Like red line) while it is scanning the QR Code. Here is Screenshot
And my ScanActivity is,
ScanCode.Java
public class ScanCode extends Activity implements OnClickListener {
Button btnScan;
TextView scanResult;
String text;
Bitmap bmp;
ImageView ivPic;
#Override
public void onCreate(Bundle icicle) {
// TODO Auto-generated method stub
super.onCreate(icicle);
setContentView(R.layout.scan_code);
initViews();
}
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
if (v.getId() == R.id.btnScanCode) {
Intent intent = new Intent(
"com.google.zxing.client.android.SCAN");
intent.putExtra("SCAN_MODE", "QR_CODE_MODE");
startActivityForResult(intent, 1);
}
}
private void initViews() {
scanResult = (TextView) findViewById(R.id.scanResult);
ivPic = (ImageView) findViewById(R.id.capturedImg);
btnScan = (Button) findViewById(R.id.btnScanCode);
btnScan.setOnClickListener(this);
}
#Override

if (requestCode == 1)
if (resultCode == Activity.RESULT_OK) {
String contents = data.getStringExtra("SCAN_RESULT");

Toast.LENGTH_SHORT).show();

}// if result_ok

I know this answer is bit late but I've just used Zxing barcode/QR-Code scanner recently in my app, if anyone has issue implementing it just follow the steps below (Using Android Studio Official IDE for android).
First add dependencies in app --> build.gradle file
dependencies {
compile 'com.journeyapps:zxing-android-embedded:3.2.0#aar'
compile 'com.google.zxing:core:3.2.1'
}
Activity Usage:
public class MainActivity extends AppCompatActivity {
Button btnScan;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
btnScan = (Button) findViewById(R.id.btnScan);
btnScan.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
scanBarcode();
}
});
}
private void scanBarcode()
{
new IntentIntegrator(this).initiateScan();
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
IntentResult result = IntentIntegrator.parseActivityResult(requestCode, resultCode, data);
if(result != null) {
if(result.getContents() == null) {
Log.d("MainActivity", "Cancelled scan");
Toast.makeText(this, "Cancelled", Toast.LENGTH_LONG).show();
} else {
Log.d("MainActivity", "Scanned");
Toast.makeText(this, "Scanned: " + result.getContents(), Toast.LENGTH_LONG).show();
}
}
}
}
If you want to use custom callback and BarCodeView. Zxing provide this functionality simply make layout file
<com.journeyapps.barcodescanner.CompoundBarcodeView
android:id="#+id/barcode_scanner"
android:layout_width="match_parent"
android:layout_height="match_parent">
</com.journeyapps.barcodescanner.CompoundBarcodeView>
<TextView
android:id="#+id/tvScanResult"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Scan Results will be shown here"
android:textColor="#android:color/white"
android:textStyle="bold"/>
In Activity use the following code
public class MainActivity extends AppCompatActivity
{
CompoundBarcodeView barcodeView;
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
barcodeView = (CompoundBarcodeView) findViewById(R.id.barcode_scanner);
barcodeView.decodeContinuous(callback);
barcodeView.setStatusText("");
}
#Override
protected void onResume()
{
super.onResume();
barcodeView.resume();
isScanned = false;
}
#Override
protected void onPause()
{
super.onPause();
barcodeView.pause();
}
#Override
public boolean onKeyDown(int keyCode, KeyEvent event)
{
return barcodeView.onKeyDown(keyCode, event) || super.onKeyDown(keyCode, event);
}
private BarcodeCallback callback = new BarcodeCallback()
{
#Override
public void barcodeResult(BarcodeResult result)
{
if (result.getText() != null)
{
barcodeView.setStatusText(result.getText());
tvscanResult.setText("Data found: " + result.getText());
}
//you can also Add preview of scanned barcode
//ImageView imageView = (ImageView) findViewById(R.id.barcodePreview);
//imageView.setImageBitmap(result.getBitmapWithResultPoints(Color.YELLOW));
}
#Override
public void possibleResultPoints(List<ResultPoint> resultPoints)
{
System.out.println("Possible Result points = " + resultPoints);
}
};
}

I'm having a bit of a trouble,, here's the gen. idea,, I have created an app a simple game-like application.. however the problem is when I try to click the button in the title screen it doesn't play the click sound.. can anyone please help me.. here's the code for my sound
public class Effects extends Activity implements MediaPlayer.OnCompletionListener {
Button mPlay;
MediaPlayer mPlayer;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mPlay = (Button)findViewById(R.id.btnStart);
mPlay.setOnClickListener(playListener);
setContentView(R.layout.activity_main);
}
#Override
public void onDestroy() {
super.onDestroy();
if(mPlayer != null) {
mPlayer.release();
}
}
private View.OnClickListener playListener = new View.OnClickListener() {
#Override
public void onClick(View v) {
if(mPlayer == null) {
try {
mPlayer = MediaPlayer.create(Effects.this, R.raw.button11);
mPlayer.start();
} catch (Exception e) {
e.printStackTrace();
}
} else {
mPlayer.stop();
mPlayer.release();
mPlayer = null;
}
}
};
#Override
public void onCompletion(MediaPlayer arg0) {
// TODO Auto-generated method stub
}
}
and here's my code for the main java that I want the sound to be played when I clicked this button
public class Main extends Activity implements OnClickListener
{
Button about;
Button Quit;
Button start;
protected void onCreate(Bundle onSavedInstanceState) {
super.onCreate(onSavedInstanceState);
setContentView(R.layout.activity_main);
about = (Button)findViewById(R.id.btnAbout);
about.setOnClickListener(this);
Quit = (Button)findViewById(R.id.btnQuit);
Quit.setOnClickListener(this);
start = (Button)findViewById(R.id.btnStart);
start.setOnClickListener(this);
}
public void onClick(View argo)
{
if(argo.getId()==R.id.btnAbout)
{
Intent i = new Intent(this,About.class);
this.startActivity(i);
}
if(argo.getId()==R.id.btnQuit)
{
Intent intent = new Intent(Intent.ACTION_MAIN);
intent.addCategory(Intent.CATEGORY_HOME);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);
}
if(argo.getId()==R.id.btnStart)
{
Intent start = new Intent(this,Howto.class);
this.startActivity(start);
Intent svc=new Intent(this,Effects.class);
startService(svc);
}
}
}
Use SoundPool to play your sounds: http://developer.android.com/reference/android/media/SoundPool.html you should init sounds in your onCreate() and then play them back in onClick()
And instead of doing thousands of pointless if(argo.getId()==R.id.btnQuit) (you should at least use else) get familiar with switch/case syntax)
