How to toggle Action Bar while touching the map like Uber

I have implemented a map that behaves like Uber app i.e pin in center and map drags under the pin and the pin gets the location from map. But I am not able to implement the touch event for toggling the action bar just exactly Uber do. Please help me to implement that feature. First I have used support map fragment but to set touch events a view was required so later on I used MapView.Below is my code:

The onCameraChangeListener is deprecated, but good news is that google has released 3 new listeners.
See: GoogleMap.OnCameraChangeListener
This interface was deprecated.
Replaced by GoogleMap.OnCameraMoveStartedListener, GoogleMap.OnCameraMoveListener and GoogleMap.OnCameraIdleListener. The order in which the deprecated onCameraChange method will be called in relation to the methods in the new camera change listeners is undefined.
I have used these listeners and now i am able get the hold and release event on map.

I believe you should add an onMarkerDragListener to your map object and do your code inside.
map.setOnMarkerDragListener(new GoogleMap.OnMarkerDragListener() {
#Override
public void onMarkerDragStart(Marker marker) {
}
#Override
public void onMarkerDrag(Marker marker) {
}
#Override
public void onMarkerDragEnd(Marker marker) {
}
});

Every time I click on button rangeincrement and rangeDecrement, the application stops. anyone have some solution?

I am trying to write code on button click in a fragment,but the buttons are not working. The buttons are set to increase and decrease the value of textview (rangeText).
I have implemented OnClickListener to my fragment.
I want to know where is the mistake.

Make the following changes to your onClick() method :

range = Integer.parseInt(rangeText.getText().toString());
if (range > 0 && range < 20) {
range = range++;
}
rangeText.setText(String.valueOf(range));

if (range > 0 && range < 20) {
range = range--;

rangeText.setText(String.valueOf(range));

I want to trasfer data (a longitude and a latitude) from one activity to another. The goal is to transfer this data to the camera, to see how the objects (augmented reality) move in real-time.

To sum up: I'd need to give to the Camera class the information about my location.

For example :
In MainActivity :
Intent intent = new Intent();
intent.setClass(this, Other_Activity.class);
intent.putExtra("EXTRA_ID", "SOME DATAS");
startActivity(intent);
In Other_Activity :
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Bundle extras = getIntent().getExtras();
if (extras != null) {
String datas= extras.getString("EXTRA_ID");
if (datas!= null) {
// do stuff
}
}
More informations here :
http://developer.android.com/reference/android/content/Intent.html
taken from here: Simple example for Intent and Bundle

Check this link please..
It says..
Use this to "put" the file...
Intent i = new Intent(FirstScreen.this, SecondScreen.class);
String keyIdentifer = null;
i.putExtra("STRING_I_NEED", strName);
startActivity(i);
Then, to retrieve the value try something like:
String newString;
if (savedInstanceState == null) {
extras = getIntent().getExtras();
if(extras == null) {
newString= null;
} else {
newString= extras.getString("STRING_I_NEED");
}
} else {
newString= (String) savedInstanceState.getSerializable("STRING_I_NEED");
}

onMarkerClick not working (v2)

I'm having some troubles with onMarkerClick
Basically for now I just want that when ANY marker previously created starts the same activity when clicked. I will implement the filtering of the marker later on.
What I get now is no error. Simply nothing happens when the marker is clicked.
Here is my source:
I'm looping through a database to populate the map and then the markers are displayed

googleMap.animateCamera(CameraUpdateFactory.newCameraPosition(cameraPosition));
//Luoghi di interesse check
if (getIntent().getIntExtra("str1", 0) == 0){
for(int x = 1; x < 6; x = x+1) {
latitude = db.getCultura(x).getCoordLat();
longitude = db.getCultura(x).getCoordLong();
googleMap.addMarker(new MarkerOptions()
.position(new LatLng(latitude, longitude)).icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_AZURE))
.title(db.getCultura(x).getName()));
}
}
if (getIntent().getIntExtra("str1", 1) == 1){
googleMap.addMarker(new MarkerOptions()
.position(new LatLng(double value, double value)).icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_GREEN))
.title("Sport"));
}
// check if map is created successfully or not

}
#Override

startActivity(i);
return false;
}
#Override

super.onResume();
initilizeMap();
}

Hope somebody can help! Thank you

In your initilizeMap() method, please add this line after you've got your map:
googleMap.setOnMarkerClickListener(this);

Here is the Log cat value of my android application.
05-07 22:16:31.636: I/lat/lng: (0.0,0.0)(17967): Current Location

Move your Log.i(latlng.toString(),"Current Location" ); code to the onLocationChanged-method, you don't have a location yet in onProviderEnabled.

mMap.setMyLocationEnabled(true); // just add one line it wil work.
