How to improve the focus speed of camera?

I use dm77/barcodescanner library to Scan QrCode. But When using This in my app, camera focus time is 1000L, and this is not optimal parameter for all phones.

I found the answer to this question with help @TeunVR in github.
You must create a class and extends from ZXingScannerView and Override setupCameraPreview and setAutoFocus .
public class ZXingAutofocusScannerView extends ZXingScannerView {
private boolean callbackFocus = false ;
public ZXingAutofocusScannerView(Context context) {
super(context);
}
@Override
public void setupCameraPreview(CameraWrapper cameraWrapper) {
Camera.Parameters parameters= cameraWrapper.mCamera.getParameters();
if(parameters != null)
{
try {
parameters.setFocusMode(Camera.Parameters.FOCUS_MODE_CONTINUOUS_PICTURE);
cameraWrapper.mCamera.setParameters(parameters);
}catch (Exception e)
{
fallbackFocus = true ;
}
// cameraWrapper.mCamera.getParameters()
}
super.setupCameraPreview(cameraWrapper);
}
@Override
public void setAutoFocus(boolean state) {
super.setAutoFocus(callbackFocus);
}
}
Now you must use this class instead ZXingScannerView.
public class SimpleScannerActivity extends AppCompatActivity implements
ZXingAutofocusScannerView.ResultHandler {
private ZXingAutofocusScannerView mScannerView;
@Override
public void onCreate(Bundle state) {
super.onCreate(state);
mScannerView = new ZXingAutofocusScannerView(this);
setContentView(mScannerView);
@Override
public void onResume() {
super.onResume();
mScannerView.setResultHandler(this);
mScannerView.startCamera();
}
@Override
public void onPause() {
super.onPause();
mScannerView.stopCamera();
}
@Override
public void handleResult(Result rawResult) {
Toast.makeText(this, ""+rawResult.getText(), Toast.LENGTH_SHORT).show();
mScannerView.resumeCameraPreview(this);
}
}
If You Use Koltin see this answer :
class ZXingAutofocusScannerView(context: Context) :
ZXingScannerView(context) {
private val TAG = ZXingAutofocusScannerView::class.qualifiedName
private var callbackFocus = false
override fun setupCameraPreview(cameraWrapper: CameraWrapper?) {
cameraWrapper?.mCamera?.parameters?.let{parameters->
try {
parameters.focusMode =
Camera.Parameters.FOCUS_MODE_CONTINUOUS_PICTURE
cameraWrapper.mCamera.parameters = parameters
}catch(ex:Exception){
Log.e(TAG, "Failed to set CONTINOUS_PICTURE", ex)
callbackFocus = true
}
}
super.setupCameraPreview(cameraWrapper)
}
override fun setAutoFocus(state: Boolean) {
super.setAutoFocus(callbackFocus)
}
}
