I've created a basic Android app that is intended to have a map with a hamburger drawer on-top of that. Each hamburger menu option will run object methods on the GoogleMap object.
The issue is that while the hamburger drawer is created and works, the map's fragment is placed in the correct place, the onCreate and subsequently onMapReady functions in MainActivity are not running meaning the GoogleMap object is never made. I added some print statements to these functions to make sure and they are never printed.
I've got two classes, HamburgerDrawer.java and MainActivity.java.
HamburgerDrawer.java:
package com.vanleusen.brighthelp;
import android.os.Bundle;
import android.support.design.widget.FloatingActionButton;
import android.support.design.widget.NavigationView;
import android.support.design.widget.Snackbar;
import android.support.v4.view.GravityCompat;
import android.support.v4.widget.DrawerLayout;
import android.support.v7.app.ActionBarDrawerToggle;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.Toolbar;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import com.google.android.gms.common.api.GoogleApiClient;
public class HamburgerDrawer extends AppCompatActivity
implements NavigationView.OnNavigationItemSelectedListener {
/**

private GoogleApiClient client;
@Override
protected void onCreate(Bundle savedInstanceState) {
//testing
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_hamburger_drawer);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
fab.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Snackbar.make(view, "Replace with your own action", Snackbar.LENGTH_LONG)
.setAction("Action", null).show();
}
});
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);
/*FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();
transaction.add(R.id.frame_container, new MyFragment());
transaction.commit();*/
//MainActivity map = new MainActivity();
}
@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.hamburger_drawer, 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_roadmap) {
System.out.println("Roadmap");
//mapData.mapTypeInterface(1);
} else if (id == R.id.nav_satellite) {
System.out.println("Satellite");
//mapData.mapTypeInterface(2);
} else if (id == R.id.nav_hybrid) {
System.out.println("Hybrid");
//mapData.mapTypeInterface(3);
} else if (id == R.id.nav_terrain) {
System.out.println("Terrain");
//mapData.mapTypeInterface(4);
} else if (id == R.id.nav_problems) {
System.out.println("Report Problems");
} else if (id == R.id.nav_contact) {
System.out.println("Contact Us");
} else if (id == R.id.nav_about) {
System.out.println("About");
}
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
drawer.closeDrawer(GravityCompat.START);
return true;
}
}
MainActivity.java:
package com.vanleusen.brighthelp;
/**
* Created by Oscar on 22/10/2016.
*/
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import com.google.android.gms.maps.CameraUpdateFactory;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.MapFragment;
import com.google.android.gms.maps.OnMapReadyCallback;
import com.google.android.gms.maps.model.LatLng;
import com.google.android.gms.maps.model.MarkerOptions;
public class MainActivity extends Activity implements OnMapReadyCallback {
private GoogleMap mMap;
public static MapFragment mapFragment;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.content_hamburger_drawer);
mapFragment = (MapFragment) getFragmentManager().findFragmentById(R.id.map);
mapFragment.getMapAsync(this);
System.out.println("Ran onCreate method");
}
@Override
public void onMapReady(GoogleMap googleMap) {
System.out.println("Ran onMapReady method");
mMap = googleMap;
// Add a marker in Sydney and move the camera
LatLng sydney = new LatLng(-34, 151);
mMap.addMarker(new MarkerOptions().position(sydney).title("Marker in Sydney"));
mMap.moveCamera(CameraUpdateFactory.newLatLng(sydney));
}
}
I have multiple layout xml files to implement the hamburger menu, although the relevant one which contains the content for the drawer is here:
content_hamburger_drawer.xml:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/content_hamburger_drawer"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="@string/appbar_scrolling_view_behavior"
tools:context="com.vanleusen.brighthelp.HamburgerDrawer"
tools:showIn="@layout/app_bar_hamburger_drawer">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Hello World!" />
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent" >
<fragment
android:id="@+id/map"
android:layout_width="match_parent"
android:layout_height="match_parent"
class="com.google.android.gms.maps.MapFragment" />
<view
android:id="@+id/myview"
android:layout_width="match_parent"
android:layout_height="fill_parent"
class="android.view.View" />
</FrameLayout>
</RelativeLayout>
And finally I've heard this may be connected to my AndroidManifest although I tried some corrections nothing seemed to work for me, I included this below:
AndroidManifest.xml:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.vanleusen.brighthelp">

I'd highly appreciate it if someone could help me work out why my map's onCreate and onMapReady functions are not being executed.
