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,

startActivity(intent);
finish();
}
}
}
}
So please again and thank you all for your time.

Can someone help me how to solve this problem? Thanks.

you can try with below link,

AdRequest adRequest = new AdRequest.Builder().build();
mAdView.loadAd(adRequest);//sample to add AdRequest.
Thank you.

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?

Google Map is not movable

Hey guys I am creating an app which gets the current co-ordinates of the user and then show them on the map which is implemented on the activity.
But my problem is that the map is not movable. I have tried getUiSettings().setScrollGesturesEnabled(true); but its not working.
The Code is given below:
public class Page1 extends AppCompatActivity implements OnMapReadyCallback {
private GoogleMap mMap;
String em,n;
private DrawerLayout mDrawer;
private Toolbar toolbar;
private NavigationView nvDrawer;
TextView tv1;
private static final int MY_PERMISSIONS_REQUEST_ACCESS_FINE_LOCATION = 2;
protected LocationManager locationManager;
Location location;
private ActionBarDrawerToggle drawerToggle;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_page1);
SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map);
mapFragment.getMapAsync(this);
toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
nvDrawer = (NavigationView) findViewById(R.id.nvView);
setupDrawerContent(nvDrawer);
// Find our drawer view
mDrawer = (DrawerLayout) findViewById(R.id.drawer_layout);
drawerToggle = setupDrawerToggle();
// Tie DrawerLayout events to the ActionBarToggle
mDrawer.addDrawerListener(drawerToggle);
locationManager = (LocationManager) getSystemService(LOCATION_SERVICE);
}
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.my_menu_option, menu);
tv1= (TextView) nvDrawer.findViewById(R.id.textView5);
Intent i=getIntent();
em=i.getStringExtra("k");
tv1.setText(em);
return true;
}
#Override
public void onMapReady(GoogleMap googleMap) {
mMap = googleMap;
Location nwLocation =getLocation(LocationManager.NETWORK_PROVIDER);
if (nwLocation != null) {
double latitude = nwLocation.getLatitude();

you are getting location from Network provider , this takes time
what about add location.LocationListener
public class Page1 extends AppCompatActivity implements OnMapReadyCallback,location.LocationListener {
#Override
public void onLocationChanged(Location location)
{
CameraPosition position = new CameraPosition.Builder()
.target(new LatLng(Location.getLatitude, Location.getLongitude))
.zoom(17).build();
mMap.animateCamera(CameraUpdateFactory.newCameraPosition(position));
}
}
