Everything is OK but the toast is not showing, "Getting Your Driver" comes again after clicking the "CALL DRIVER"

As I wrote in findDriver(). block Driver key showing with debug but not toasting and the Call Driver Button is showing once but after clicking it is moving back to the previous state which is Getting your Driver, I have tried my best from my short experience, if anyone can help I am grateful.

private void requestPickupHere(String uid) {
        DatabaseReference dbRequest = FirebaseDatabase.getInstance().getReference(Common.pickup_request_tbl);
        GeoFire mGeoFire = new GeoFire(dbRequest);
        mGeoFire.setLocation(uid, new GeoLocation(mLastLocation.getLongitude(), mLastLocation.getLatitude()), new GeoFire.CompletionListener() {
            @Override
            public void onComplete(String key, DatabaseError error) {

            }
        });
        if (mUserMarker.isVisible())
            mUserMarker.remove();
        //add new marker
        mUserMarker = mMap.addMarker(new MarkerOptions().title("Pickup Here").snippet("")
                .position(new LatLng(mLastLocation.getLatitude(), mLastLocation.getLongitude()))
                .icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_RED)));
        mUserMarker.showInfoWindow();

        btnRequestPick.setText("Getting your DRIVER..");
        findDriver();
    }


    private void findDriver() {
        DatabaseReference databaseReference = FirebaseDatabase.getInstance().getReference(Common.driver_tbl);
        GeoFire gfDrivers = new GeoFire(databaseReference);
        GeoQuery geoQuery = gfDrivers.queryAtLocation(new GeoLocation(mLastLocation.getLatitude(), mLastLocation.getLongitude()), radius);
        geoQuery.removeAllListeners();
        geoQuery.addGeoQueryEventListener(new GeoQueryEventListener() {
            @Override
            public void onKeyEntered(String key, GeoLocation location) {
                //if found driver
                if (!isDriverFound) {
                    isDriverFound = true;
                    driverId = key;
                    btnRequestPick.setText("CALL DRIVER");
                    Toast.makeText(Home.this, "Found: " + key, Toast.LENGTH_LONG).show();
                }
            }

            @Override
            public void onKeyExited(String key) {

            }

            @Override
            public void onKeyMoved(String key, GeoLocation location) {

            }

            @Override
            public void onGeoQueryReady() {
                //if still not found driver
                if (!isDriverFound) {
                    radius++;
                    findDriver();
                }
            }

            @Override
            public void onGeoQueryError(DatabaseError error) {

            }
        });
    }
