Belong my xml file :
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"

android:layout_height="match_parent"
tools:context=".MainActivity">
<EditText
android:id="#+id/edittext"
android:layout_width="match_parent"

And my main code:

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
checkPermission();

//getting all the matches
ArrayList<String> matches = bundle
.getStringArrayList(SpeechRecognizer.RESULTS_RECOGNITION);
//displaying the first match
if (matches != null) {
edittext.setText(matches.get(0));
}
}
#Override
public void onPartialResults(Bundle bundle) {
}
#Override
public void onEvent(int i, Bundle bundle) {
}
});
findViewById(R.id.button).setOnTouchListener(new View.OnTouchListener() {
#Override
public boolean onTouch(View view, MotionEvent motionEvent) {
switch (motionEvent.getAction()) {
case MotionEvent.ACTION_UP:
mSpeechRecognizer.stopListening();
edittext.setHint("You will see input here");
break;
case MotionEvent.ACTION_DOWN:
mSpeechRecognizer.startListening(mSpeechRecognizerIntent);
edittext.setText("");
edittext.setHint("Listening...");
break;
}
return false;
}
});
}
private void checkPermission() {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
if (!(ContextCompat.checkSelfPermission(this, Manifest.permission.RECORD_AUDIO) == PackageManager.PERMISSION_GRANTED)) {
Intent intent = new Intent(Settings.ACTION_APPLICATION_DETAILS_SETTINGS,
Uri.parse("package:" + getPackageName()));
startActivity(intent);
finish();
}
}
}
}
So please again and thank you all for your time.

Flashlight Fragment Android Studio

I have created a flashlight fragment for my app and I have implemented this code and turning the flashlight on works, but I can't turn it off.
I tried to switch the light on and off from one button or like now from two but it made no difference.
When I switch the fragment, the light turns off.
I hope anyone knows what to do.
Thx
public class Flashlight extends Fragment implements SurfaceHolder.Callback {

Manifest:
<uses-permission android:name="android.permission.CAMERA" />
<uses-feature android:name="android.hardware.camera" />
<uses-permission android:name="android.permission.FLASHLIGHT" />
XML:
<?xml version="1.0" encoding="utf-8"?>

Okay update the permission in the manifest file as below:

android:permissionGroup="android.permission-group.HARDWARE_CONTROLS"
android:protectionLevel="normal"
android:label="#string/permlab_flashlight"
android:description="#string/permdesc_flashlight" />
Try to off the light using the below code:
cam.stopPreview();
cam.release(); // Very Important line

In which line?
private void turnOffLight() {
if (lightIsOn) {
if (camera == null || parameters == null) {
return;
}
camera = Camera.open();
parameters = camera.getParameters();
parameters.setFlashMode(Camera.Parameters.FLASH_MODE_OFF);
camera.setParameters(parameters);
camera.stopPreview();
camera.release(); // Very Important line
lightIsOn = false;
button_OnOff.setText("On");
}
}

Mobile vision how to resize?

I've been looking for information on Google for 2 days. But all
without results.
I want to use not the full screen mode, but the reduced one, so that
you can scan a certain area.
In Api Google, I also did not find what I needed.
The variant with resizing in SurfaceView is attached with a picture.
As you can see, the result is deplorable ((.
Is there a solution to my problem?

SurfaceView doesn't display camera

I am trying to display a camera on in my android app, but all I am getting is a black box where the SurfaceView is located.
I am using this simple XML layout:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
tools:context="com.lazylayer.photoshoot.MainActivity">
<SurfaceView
android:id="#+id/surface_view"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</RelativeLayout>
With this Activity:
public class MainActivity extends AppCompatActivity implements SurfaceHolder.Callback {
SurfaceView surfaceView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
surfaceView = (SurfaceView)findViewById(R.id.surface_view);
}
#Override
public void surfaceCreated(SurfaceHolder holder) {
try{
CameraManager cameraManager = (CameraManager)getSystemService(Context.CAMERA_SERVICE);
String[] cameras = cameraManager.getCameraIdList();
cameraManager.openCamera(cameras[0], deviceCallback, null);
} catch (CameraAccessException e) {
e.printStackTrace();
}
}
#Override
public void surfaceChanged(SurfaceHolder holder, int format, int width, int height) {}
#Override
public void surfaceDestroyed(SurfaceHolder holder) {}
CameraDevice.StateCallback deviceCallback = new CameraDevice.StateCallback() {
#Override
public void onOpened(CameraDevice camera) {
try {
List<Surface> surfaceList = Collections.singletonList(surfaceView.getHolder().getSurface());
camera.createCaptureSession(surfaceList, sessionCallback, null);
} catch (CameraAccessException e) {
e.printStackTrace();
}
}
#Override
public void onDisconnected(CameraDevice camera) {}
#Override
public void onError(CameraDevice camera, int error) {}
};
CameraCaptureSession.StateCallback sessionCallback = new CameraCaptureSession.StateCallback() {
#Override
public void onConfigured(CameraCaptureSession session) {
}
#Override
public void onConfigureFailed(CameraCaptureSession session) {}
};
}
Here is what gets displayed when the app is ran on my phone:

I was able to fix the issue by using a FrameLayout instead of a SurfaceView
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/camera_view">
</FrameLayout>
