Develop Reference

I have added profile activity, then added a dynamic image profile and username. After i did that, the navigation buttons are not working at all

here is my java code
that is the java code, I have added navigation profile activity then run it after retrieving the image and user name from the firebase. the navigation buttons are no more clickable

}
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
drawer.closeDrawer(GravityCompat.START);
return true;
}
}

To receive callbacks when the user taps a list item in the drawer, implement the OnNavigationItemSelectedListener and attach it to your NavigationView by calling setNavigationItemSelectedListener().
You need to attach the navigationView to listener
navigationView.setNavigationItemSelectedListener(this);
Hope this helps.

Failed to convert value of type java.util.HashMap to boolean

I'm trying to detect the connection state of my app, but this is the Error am facing:
Failed to convert value of type java.util.HashMap to boolean
I am using Firebase. The error is on line:
boolean connected = dataSnapshot.getValue(Boolean.class);
So the Error comes in the OnDataFinishedLoading() method . Data was coming at first, but now I just want to detect the apps network connection. Below is my code:
public class MainActivity extends AppCompatActivity

Ok, so the core problem you're having is that Firebase is returning a Map, not a Boolean. That's because of the way you have this configured--every time a child is added, you try to look at the DataSnapshot (that's what the listener you setup does), and tries to get a Boolean value out. However, the Snapshot is the child added to the database (and not a boolean) so instead you get a map out.
If all you want to do is verify that a child was added successfully, I'd do the following:
public void onChildAdded(DataSnapshot dataSnapshot, String s) {
Object value = dataSnapshot.getValue();
if(value != null) {
pb.setVisibility(View.INVISIBLE);
LoadData(dataSnapshot);
} else{
Toast.makeText(MainActivity.this,"No Network",Toast.LENGTH_LONG).show();
}
}
However, this isn't really going to solve your network connectivity problem. It'll just do stuff whenever a non-null child gets added to the firebase object, which could happen frequently. Also in LoadData, you don't check to make sure that the object passed in isn't null.

How to get location in Fragment?

Hi im try to find location in fragment. but i cannot get location.
LocationManager locationmanager= (LocationManager) getActivity().getSystemService(Context.LOCATION_SERVICE); return null.how can i fix it

Please add logcat errors or result for more details. Meanwhile try this in your onMapready:

// getting location of user
final double latitude = location.getLatitude();
final double longitude = location.getLongitude();
// do something with Latlng
}
#Override
public void onStatusChanged(String provider, int status, Bundle extras) {
}
#Override
public void onProviderEnabled(String provider) {
// do something
}
#Override
public void onProviderDisabled(String provider) {
// notify user "GPS or Network provider" not available
}
};
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 10000, 500, locationListener);
locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 10000, 500, locationListener);
}
else {
// do something with last know location
}

Try by putting
LocationManager locationmanager= (LocationManager) getActivity().getSystemService(Context.LOCATION_SERVICE); outside of onMapReady

Changing to Landscape crashes my Android app

I am developing an app and want users to be able to use their phones horizontally or vertically, however, if I start in portrait and switch to landscape, the app crashes. It also crashes if I start landscape and switch to portrait.

Hii for working in landscape and portrait mode, you have to use saved instance and restore saved instance or else your application values
googleApiClient,lastLocation,zip,user values may have null value and causes this issue
#Override
public void onSaveInstanceState(Bundle savedInstanceState) {
super.onSaveInstanceState(savedInstanceState);
// Save UI state changes to the savedInstanceState.
// This bundle will be passed to onCreate if the process is
// killed and restarted.
savedInstanceState.putBoolean("MyBoolean", true);
savedInstanceState.putDouble("myDouble", 1.9);
savedInstanceState.putInt("MyInt", 1);
savedInstanceState.putString("MyString", "Welcome back to Android");
savedInstanceState.putParcelable("parcelable", "");
savedInstanceState.putSerializable("serializable", "");
}
The Bundle is essentially a way of storing a NVP ("Name-Value Pair") map, and it will get passed in to onCreate() and also onRestoreInstanceState() where you'd extract the values like this:
#Override
public void onRestoreInstanceState(Bundle savedInstanceState) {
super.onRestoreInstanceState(savedInstanceState);
// Restore UI state from the savedInstanceState.
// This bundle has also been passed to onCreate.
boolean myBoolean = savedInstanceState.getBoolean("MyBoolean");
double myDouble = savedInstanceState.getDouble("myDouble");
int myInt = savedInstanceState.getInt("MyInt");
String myString = savedInstanceState.getString("MyString");
}

Navigation drawer not working on activities using fragments

I've been trying to add a Nav Drawer to my app. I have this MapsActivty which is my main activity.
public class MapsActivity extends FragmentActivity implements OnMapReadyCallback {
public GoogleMap mMap;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
.findFragmentById(R.id.map);
mapFragment.getMapAsync(this);
}
#SuppressWarnings("StatementWithEmptyBody")
public void onMapSearch(View view) {
EditText locationSearch = (EditText) findViewById(R.id.editText);
String location = locationSearch.getText().toString();
List<Address> addressList = null;
if (location != null || !location.equals("")) {
Geocoder geocoder = new Geocoder(this);
try {
addressList = geocoder.getFromLocationName(location, 1);
} catch (IOException e) {
e.printStackTrace();
}
Address address = addressList.get(0);
LatLng latLng = new LatLng(address.getLatitude(), address.getLongitude());
mMap.addMarker(new MarkerOptions().position(latLng).title("Marker"));
mMap.animateCamera(CameraUpdateFactory.newLatLng(latLng));
}
}
public void onNormalMap(View view) {
mMap.setMapType(GoogleMap.MAP_TYPE_NORMAL);
}
public void onSatelliteMap(View view) {
mMap.setMapType(GoogleMap.MAP_TYPE_SATELLITE);
}
public void onTerrainMap(View view) {
mMap.setMapType(GoogleMap.MAP_TYPE_TERRAIN);
}
public void onHybridMap(View view) {
mMap.setMapType(GoogleMap.MAP_TYPE_HYBRID);
}
public static double lng;
public static double lat;
#Override
public void onMapReady(final GoogleMap googleMap) {
mMap = googleMap;
Button btn = (Button) findViewById(R.id.button);
btn.setOnClickListener(new View.OnClickListener()
{

{
Intent intent = new Intent (v.getContext(), RegistroInfo.class);
intent.putExtra("longitud", String.valueOf(lng));
intent.putExtra("latitud", String.valueOf(lat));
startActivityForResult(intent, 0);
} });
//View v;
mMap.setOnMapLongClickListener(new GoogleMap.OnMapLongClickListener() {
#Override
public void onMapLongClick(LatLng point) {
mMap.addMarker(new MarkerOptions().position(point).title("Custom location").icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_RED)));
RegistroInfo regis = new RegistroInfo();
lng = point.longitude;
lat = point.latitude;
}
});
// Add a marker in Sydney and move the camera
LatLng cusco = new LatLng(-13.537733, -71.903838);
mMap.addMarker(new MarkerOptions().position(cusco).title("Cusco, Peru"));
float zoomLevel = 16; //This goes up to 21
mMap.moveCamera(CameraUpdateFactory.newLatLngZoom(cusco, zoomLevel));
mMap.moveCamera(CameraUpdateFactory.newLatLng(cusco));
if (ActivityCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_FINE_LOCATION)
!= PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this,
android.Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED)
{
return;
}
mMap.getUiSettings().setMyLocationButtonEnabled(true);
mMap.setMyLocationEnabled(true);
mMap.getUiSettings().setMyLocationButtonEnabled(true);
mMap.getUiSettings().setZoomControlsEnabled(true);
mMap.getUiSettings().setIndoorLevelPickerEnabled(true);}}
NOTICE that a use extends FragmentActivityand i saw that i could use extends MenuActivity from my MenuActivity I tried this post [Same Navigation Drawer in different Activities)
From my Menu Activity i have some items, which are the MapsActivity( nav_MenuPrincipal ), PerfilActivity(another activity showing information of current user) nav_perfil, NormalMap(style of map) nav_normal, SatelliteMap(style of map) nav_satellite, TerrainMap(style of map)nav_terrainmap, HybridMap(style of map)nav_hybrid
Here goes the MenuActivity
public class MenuActivity extends AppCompatActivity
implements NavigationView.OnNavigationItemSelectedListener {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_menu);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
drawer.setDrawerListener(toggle);
toggle.syncState();
NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
navigationView.setNavigationItemSelectedListener(this);
}
#Override
public void onBackPressed() {
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
if (drawer.isDrawerOpen(GravityCompat.START)) {
drawer.closeDrawer(GravityCompat.START);
} else {
super.onBackPressed();
}
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
#SuppressWarnings("StatementWithEmptyBody")
#Override
public boolean onNavigationItemSelected(MenuItem item) {
// Handle navigation view item clicks here.
int id = item.getItemId();
if (id == R.id.nav_MenuPrincipal) {
startActivity(new Intent(this, MapsActivity.class));
return true;
}
else if (id == R.id.nav_perfil) {
}
else if (id == R.id.nav_suggestions) {
} else if (id == R.id.nav_normalmap) {
} else if (id == R.id.nav_satellitemap) {
} else if (id == R.id.nav_terrainmap) {
} else if (id == R.id.nav_hybridmap) {
} else if (id == R.id.nav_aboutus) {
}
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
drawer.closeDrawer(GravityCompat.START);
return true;
}
}
Notice that I've tried this if (id == R.id.nav_MenuPrincipal) { startActivity(new Intent(this, MapsActivity.class)); return true; }, it works but not showing the menu bar.
For the items called Normal, Satellite, Terrain, Hybridi just want to change the style of the map for the MapsActivity
Now I'm using a LoginActivity which is already connected to a DB on a Hosting, it has the intent filter. Then i want to show my MainActivity (MapsActivity) but with that Menu (NavigationDrawer)
Thank you very much.
