How to implement speech to text in my app

I am building an app that utilities speech to text, in my code everything seems fine till it gets to protected void onActivityResult method to handle the results, it generates an error saying onActivityResult is a variable and then if I delete the access modifier, it sees it as a method then it generates another error in the parameters saying identifier expected and token is missing
Any help would be greatly appreciated.
My code
private static final int SPEECH_REQUEST_CODE = 100;
// Create an intent that can start the Speech Recognizer activity
private void displaySpeechRecognizer() {
Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,
RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
// Start the activity, the intent will be populated with the speech text
startActivityForResult(intent, SPEECH_REQUEST_CODE);
}
// This callback is invoked when the Speech Recognizer returns.
// This is where you process the intent and extract the speech text from the intent.
#Override
protected void onActivityResult(int requestCode, int resultCode,
Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == SPEECH_REQUEST_CODE && resultCode == RESULT_OK) {
List<String> results = data.getStringArrayListExtra(
RecognizerIntent.EXTRA_RESULTS);
Output.setText(results.get(0));
}
}

DO it like this:
private void displaySpeechRecognizer() {
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(getApplicationContext(),
getString(R.string.speech_not_supported),
Toast.LENGTH_SHORT).show();
}
}
And in onActivityResult:
#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);
txtSpeechInput.setText(result.get(0));
}
break;
}
}
}
And in onCreate:
//Button you craete to start speech recognition
Button btnSpeak = (ImageButton) findViewById(R.id.btnSpeak);
// hide the action bar
//getActionBar().hide();
btnSpeak.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
displaySpeechRecognizer();
}
});

How to add an image captured on camera to imageviewer in Android using java? I have tried the following code

I have added Camera permissions as well which is working perfectly but the image view is not holding the image that is captured. The manifest file is also proper still. The app isn't crashing even it is not showing any errors as well. And I even want to add the image to the database.
public class RiderProfile extends AppCompatActivity {
ImageView imgDp,imgDlFront,imgDlback;
TextView txtDp,txtDl;
Button btnSave;
public static final int CAMERA_REQUEST = 1888;
private static final String TAG = "1111";
private static final int MY_CAMERA_PERMISSION_CODE = 100;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_rider_profile);
imgDp = (ImageView)findViewById(R.id.imgDp);
imgDlFront = (ImageView)findViewById(R.id.imgDlFront);
imgDlback = (ImageView)findViewById(R.id.imgDlback);
txtDp = (TextView) findViewById(R.id.txtDp);
txtDl = (TextView)findViewById(R.id.txtDl);
btnSave = (Button) findViewById(R.id.btnSave);
imgDp.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent i = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(i, CAMERA_REQUEST);
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == CAMERA_REQUEST && resultCode == Activity.RESULT_OK) {
Bitmap photo1 = (Bitmap) data.getExtras().get("data");
Log.d(TAG, "onActivityResult: click ");
imgDp.setImageBitmap(photo1);
}
}
});
imgDlFront.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent i = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(i, CAMERA_REQUEST);
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == CAMERA_REQUEST && resultCode == Activity.RESULT_OK) {
Bitmap photo2 = (Bitmap) data.getExtras().get("data");
Log.d(TAG, "onActivityResult: click ");
imgDlFront.setImageBitmap(photo2);
}
}
});
imgDlback.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent i = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(i, CAMERA_REQUEST);
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == CAMERA_REQUEST && resultCode == Activity.RESULT_OK) {
Bitmap photo3 = (Bitmap) data.getExtras().get("data");
Log.d(TAG, "onActivityResult: click ");
imgDlback.setImageBitmap(photo3);
}
}
});
}
}

1. #Override
public void onCameraOpen() {
Intent pictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
if (pictureIntent.resolveActivity(getPackageManager()) != null) {
try {
imageFile = CameraUtils.createImageFile(this);
} catch (IOException e) {
e.printStackTrace();
return;
}
imageUri = FileProvider.getUriForFile(this, getPackageName() + ".provider", imageFile);
pictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);
startActivityForResult(pictureIntent, IntentRequestCode.RESULT_CODE_IMAGE_CAPTURE);
}
}
2. #Override
protected void onActivityResult(int requestCode, int resultCode, #Nullable Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode) {
case RESULT_CODE_IMAGE_CAPTURE:
if (resultCode == RESULT_OK) {
onCaptureImage(imageFile, imageUri);
} else {
Toast.makeText(this, "Camera canceled", Toast.LENGTH_SHORT).show();
}
break;
}
}
3. void onCaptureImage(File imageFile, Uri imageUri) {
Uri uri = Uri.fromFile(imageFile);
String selectedImagePath = CameraUtils.getPath(application, uri);
File file1 = new File(selectedImagePath);
if (file1.length() != 0) {
FileAttachments b_data = new FileAttachments();
b_data.setFileName(file1.getName());
CameraUtils.writeScaledDownImage(file1, getApplication());
b_data.setFile(file1);
}
}

Integrate git project on an existing project startActivityForResult and onActivityResult android

I implemented this git on my current project without cloning
implementation 'com.github.adityaarora1:LiveEdgeDetection:master-SNAPSHOT'
But I'm unable to call it on my method. The document says
Start startActivityForResult from your activity
startActivityForResult(new Intent(this, ScanActivity.class), REQUEST_CODE);
Get a file path for cropped image on onActivityResult
String filePath = data.getExtras().getString(ScanConstants.SCANNED_RESULT);
Bitmap baseBitmap = ScanUtils.decodeBitmapFromFile(filePath, ScanConstants.IMAGE_NAME);
So I tried calling like this onClick button from a new Class
scan.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent myIntent = new Intent(MainActivity.this,
ScanActivity.class);
startActivity(myIntent);
}
and put the rest inside my onActivityResult
protected void onActivityResult(int requestCode, int resultCode, #Nullable Intent data) {
super.onActivityResult(requestCode, resultCode, data);
String filePath = data.getExtras().getString(ScanConstants.SCANNED_RESULT);
Bitmap baseBitmap = ScanUtils.decodeBitmapFromFile(filePath, ScanConstants.IMAGE_NAME);
}
Edit: here is the MainActivity the author used on git I tried using it I get this error:
scannedImageView = findViewById(com.adityaarora.liveedgedetection.R.id.scanned_image);
MainActivity (imported)
private static final int REQUEST_CODE = 101;
private ImageView scannedImageView;
Button scan;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_scan);
scannedImageView = findViewById(com.adityaarora.liveedgedetection.R.id.scanned_image);
startScan();
scan = findViewById(R.id.open_scan);
scan.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent myIntent = new Intent(ScanActivity2.this,
ScanActivity.class);
startActivityForResult(myIntent ,111);
}
});
}
private void startScan() {
Intent intent = new Intent(this, ScanActivity.class);
startActivityForResult(intent, REQUEST_CODE);
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == REQUEST_CODE) {
if(resultCode == Activity.RESULT_OK) {
if(null != data && null != data.getExtras()) {
String filePath = data.getExtras().getString(ScanConstants.SCANNED_RESULT);
Bitmap baseBitmap = ScanUtils.decodeBitmapFromFile(filePath, ScanConstants.IMAGE_NAME);
scannedImageView.setScaleType(ImageView.ScaleType.FIT_CENTER);
scannedImageView.setImageBitmap(baseBitmap);
}
} else if(resultCode == Activity.RESULT_CANCELED) {
finish();
}
}
}
Update :
After some research I found that the imported project was on read file only and cannot be changed (ScanActivity.java) and my current project was updated sdk 28 which is different from the one Imported so there is some errors in ScanActivity which Is why the button (technically) wasn't working

You should use startActivityForResult instead of startActivity like below.
scan.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent myIntent = new Intent(MainActivity.this,
ScanActivity.class);
startActivityForResult(myIntent ,111);
}
});
and modify your onActivityResult like
protected void onActivityResult(int requestCode, int resultCode, #Nullable Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if(resultCode == Activity.RESULT_OK && requestCode == 111){
String filePath = data.getExtras().getString(ScanConstants.SCANNED_RESULT);
Bitmap baseBitmap = ScanUtils.decodeBitmapFromFile(filePath, ScanConstants.IMAGE_NAME);
Log.d("YourTAG","File Path "+filePath);
// here you can set bitmap to your image view
yourImageView.setImageBitmap(baseBitmap);
}
}
UPDATE
You Main Activity should be like
private static final int REQUEST_CODE = 111;
private ImageView scannedImageView;
Button scan;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_scan);
scannedImageView = findViewById(R.id.scanned_image); // this ImageView should be in your activity_scan.xml file with same id(scanned_image)
startScan();
scan = findViewById(R.id.open_scan);
scan.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
startScan();
}
});
}
private void startScan() {
Intent intent = new Intent(ScanActivity2.this, ScanActivity.class);
startActivityForResult(intent, REQUEST_CODE);
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == REQUEST_CODE) {
if(resultCode == Activity.RESULT_OK) {
if(null != data && null != data.getExtras()) {
String filePath = data.getExtras().getString(ScanConstants.SCANNED_RESULT);
Bitmap baseBitmap = ScanUtils.decodeBitmapFromFile(filePath, ScanConstants.IMAGE_NAME);
scannedImageView.setScaleType(ImageView.ScaleType.FIT_CENTER);
scannedImageView.setImageBitmap(baseBitmap);
}
} else if(resultCode == Activity.RESULT_CANCELED) {
finish();
}
}
}
Demo project
I have uploaded a demo project on Github which is integrated LiveEdgeDetection library and working as expected.

Zxing Scanner App, How to show a result as a yes or no?

Using zxing on Android Studio with empty activity and 4.4 KitKat. I would like to show the result as a yes or no. I would like to reference a google sheet with the UPC codes. If the UPC is in the spreadsheet already then show "YES" or if the UPC is not in the spreadsheet show "NO". Can I use an "If, Else" in the MainActivity java code using only the UPC column on the google sheet?
#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();
}
} else {
super.onActivityResult(requestCode, resultCode, data);
I want to show this code as a "Yes" or "NO" based on if the scanned barcode is already in the spreadsheet. My question is how to get the spreadsheet to communicate with the scanner or can copy all of the barcodes from the spreadsheet in a boolean?
Set<String> getStringSet (String key,
Set<String> defValues)
makeText(Context context, int resId, int duration)
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();
}
So above is what ive come up with from search. Is it practical to use shared preference to store my data(1000 UPC) use ZXING to parse as well as IF ELSE to check the code and finally TOAST to show "YES" or "NO" based on if my result is located in the shared preference?
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button button = this.findViewById(R.id.button);
final Activity activity = this;
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
IntentIntegrator integrator = new IntentIntegrator(activity);
integrator.setDesiredBarcodeFormats(IntentIntegrator.ALL_CODE_TYPES);
integrator.setPrompt("Scan");
integrator.setCameraId(0);
integrator.setBeepEnabled(false);
integrator.setBarcodeImageEnabled(false);
integrator.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();
}
} else {
super.onActivityResult(requestCode, resultCode, data);
}
}
public void scanCode(View view) {
}
public class myWebView extends MainActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
WebView webview = new WebView(this);
setContentView(webview);
WebView myWebView = findViewById(R.id.myWebView);
myWebView.setWebViewClient(new MyWebViewClient());
WebSettings webSettings = myWebView.getSettings();
webSettings.setJavaScriptEnabled(true);
webview.loadUrl("https://google.com/");
}
private class MyWebViewClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
startActivity(intent);
return true;
}
}
}
}

for segregation of code you need to create SacnActivity as a separate activity which is extend Activity and impliments ZXingScannerView.ResultHandler and call from the MainActivity and give call back to Mainactivity in onActivityResult().
MainActivity
public class MainActivity extends Activity{
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
scan = (Button)findViewById(R.id.btnScan);
scan.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
startActivityForResult(new Intent(MainActivity.this,SacnActivity .class),1);
}
});
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == 1) {
if(resultCode == Activity.RESULT_OK){
String result=data.getStringExtra("result");
Log.d("result================>",""+result);
try {
//processData(result);
} catch (Exception e) {
e.printStackTrace();
}
}
if (resultCode == Activity.RESULT_CANCELED) {

Voice Recognition without Google Dialog

I am trying to use the Speech recognition without dialog with RecognitionListener, but it doesn't work. The following codes are the way now I use, and the bottom codes (test part) are for checking that could phone receive my commanding. Additionally, I have added permissions Audio. Finally, I don't want there have any button.
This is my first time asking question, so hope I dont violate any unspoken rules.
Thank you very much,
