getSupportActionBar().setHomeButtonEnabled(true);
mNavigationView = (NavigationView) findViewById(R.id.navigation_view);
mNavigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {
@Override
public boolean onNavigationItemSelected(MenuItem menuItem) {
if (menuItem.isChecked()) menuItem.setChecked(false);
else menuItem.setChecked(true);
//Closing drawer on item click
mDrawerlayout.closeDrawers();
//Check to see which item was being clicked and perform appropriate action
switch (menuItem.getItemId()) {
//Replacing the main content with ContentFragment Which is our Inbox View;
case R.id.events:

Eco_events fragment = new Eco_events();
android.support.v4.app.FragmentTransaction fragmentTransaction = getSupportFragmentManager().beginTransaction();
fragmentTransaction.replace(R.id.frame, fragment);
fragmentTransaction.commit();
return true;
// show a toast on click

}
}
});
// Initializing Drawer Layout and ActionBarToggle
mDrawerlayout = (DrawerLayout) findViewById(R.id.drawer);
mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerlayout, toolbar, R.string.drawerOpened, R.string.drawerOpened) {
@Override
