How can I call a function when navigation drawer is toggled?

I want to change the items on my navigation drawer based on the user that has logged in and if they have premium account or not.
I know how to make items visible and invisible, but I was wondering if I can put a function somewhere that when ever it's toggled it would set the visibility of them items and also change the header based on the user profile.
thank you all in advance.

Add a DrawerListener to your DrawerLayout
mDrawerLayout.addDrawerListener(new DrawerLayout.DrawerListener() {
#Override
public void onDrawerSlide(#NonNull View drawerView, float slideOffset) {
}
#Override
public void onDrawerOpened(#NonNull View drawerView) {
}
#Override
public void onDrawerClosed(#NonNull View drawerView) {
}
#Override
public void onDrawerStateChanged(int newState) {
}
});

I suggest you add a DrawerListener to your DrawerLayout
drawerLayout.addDrawerListener(new DrawerToggle());
DrawerToggle is an extension of android.support.v4.widget.SimpleDrawerListener in which you've overidden onClick() and onDrawerSlide()
#Override
public void onClick(View v) {
mDrawerLayout.openDrawer(GravityCompat.START);
}
#Override
public void onDrawerSlide(View drawerView, float slideOffset) {
super.onDrawerSlide(drawerView, slideOffset);
}
You can use these methods to catch drawer toggle event

Change toggle button image Icon In Navigation Drawer right to left

I Want to change the navigation drawer toggle icon for close and open.
I downloaded the sample code from this link:
http://vardhan-justlikethat.blogspot.in/2014/02/android-slider-from-right-to-left.html
But there is no method call when navigation drawer closed.
I required to change that toggle button with some other image,
Thanks.

in res/drawable-hdpi/ ,res/drawable-mdpi/ , res/drawable-xhdpi/ and res/drawable-xxhdpi/ you have ic_drawer.png change that with your image

DrawerListener:
DrawerListener drawerListener = new DrawerListener() {
#Override
public void onDrawerClosed(View drawerView) {
drawerHandleImage.setImageResource(R.id.closed);
}
#Override
public void onDrawerOpened(View drawerView) {
drawerHandleImage.setImageResource(R.id.opened);
}
#Override
public void onDrawerSlide(View drawerView, float slideOffset) { }
#Override
public void onDrawerStateChanged(int newState) { }
};
Set the listener to your DrawerLayout:
drawerLayout.setDrawerListener(drawerListener);

Android Material Design with NavigationDrawer and BackButton

I have a toolbar with the "back button" on the left side and a button to to open the navigation drawer fragment on the right side. Now, if I click on the button on the right side and then on the back button on the left side, the app crashed and said : "No drawer view found with gravity LEFT". Yeah the fragment is on the right side and the question is how can I avoid this? Here is my code:
in OnCreate:
setSupportActionBar(toolbarTutorial);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
in onOptionsItemSelected:
if (id == R.id.editInformations) {
drawerLayout.setDrawerListener(new ActionBarDrawerToggle(ProfileActivity.this,
drawerLayout, toolbarTutorial, R.string.drawer_open,R.string.drawer_close){
#Override
public void onDrawerClosed(View drawerView) {
super.onDrawerClosed(drawerView);
mSlideState = false;
}
#Override
public void onDrawerOpened(View drawerView) {
super.onDrawerOpened(drawerView);
mSlideState = true;
}
});
clickEventSlide();
}
and the clickEventSlide method:
public void clickEventSlide(){
if(mSlideState){
drawerLayout.closeDrawer(Gravity.END);
}else{
drawerLayout.openDrawer(Gravity.END);
}}

How to set navigation home button in android for appcompat activity for toolbar?

I am using the appcompat activity for Android v-21. I want to enable the home button which I have set it to true in my code. I also have overridden the onOptionsItemSelected but it's still not working.
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_apply_card);
mToolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(mToolbar);
//Action bar
getSupportActionBar().setHomeButtonEnabled(true);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
onBackPressed();
return true;
}

Simple way to add action bar home enable in Appcompat activity
getSupportActionBar().show();
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
Add this two pulic functions in your activity also--
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case android.R.id.home:
// app icon in action bar clicked; go home
this.finish();
return true;
default:
return super.onOptionsItemSelected(item);
}
}
#Override
public void onBackPressed() {
// TODO Auto-generated method stub
super.onBackPressed();
}

Following code snippet set navigation icon in toolbar,
toolbar.setNavigationIcon(R.mipmap.ic_launcher);
I hope it will help you.

I know it is an old question but in order to prevent others to devote their time to solve this issue, I want to share the working method for me.
I am not sure about the reason of this. Probably, since ActionBar is deprecated and gave way to Toolbar after AppCompat, some methods of AppCompatActivity may not work as it is expected. Although the Burger (navigation button) is defined as the home button of ActionBar, we could not control click events of this button by using .onOptionsItemSelected(MenuItem). Toolbar view presents us another method to achieve this, toolbar.setNavigationOnClickListener(View.OnClickListener).
To exemplify, I tried to use balysv's MaterialMenuIcon with this method instead of .onOptionsItemSelected(MenuItem) as follows:
private void setupToolbar() {
toolbar = (Toolbar) ((LinearLayout) findViewById(R.id.app_bar)).getChildAt(0);
setSupportActionBar(toolbar);
toolbar.setNavigationOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (drawerLayout.isDrawerVisible(GravityCompat.START)) {
drawerLayout.closeDrawer(GravityCompat.START);
materialMenu.animatePressedState(MaterialMenuDrawable.IconState.BURGER);
} else {
drawerLayout.openDrawer(GravityCompat.START);
materialMenu.animatePressedState(MaterialMenuDrawable.IconState.ARROW);
}
}
});
materialMenu = new MaterialMenuIconToolbar(this, Color.WHITE, MaterialMenuDrawable.Stroke.THIN) {
#Override public int getToolbarViewId() {
return R.id.toolbar;
}
};
drawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
drawerLayout.setDrawerListener(new DrawerLayout.SimpleDrawerListener() {
#Override
public void onDrawerSlide(View drawerView, float slideOffset) {
super.onDrawerSlide(drawerView, slideOffset);
materialMenu.setTransformationOffset(
MaterialMenuDrawable.AnimationState.BURGER_ARROW,
isDrawerOpened ? 2 - slideOffset : slideOffset
);
}
#Override
public void onDrawerOpened(View drawerView) {
super.onDrawerOpened(drawerView);
isDrawerOpened = true;
}
#Override
public void onDrawerClosed(View drawerView) {
super.onDrawerClosed(drawerView);
isDrawerOpened = false;
}
#Override
public void onDrawerStateChanged(int newState) {
super.onDrawerStateChanged(newState);
if (newState == DrawerLayout.STATE_IDLE) {
if (isDrawerOpened) materialMenu.setState(MaterialMenuDrawable.IconState.ARROW);
else materialMenu.setState(MaterialMenuDrawable.IconState.BURGER);
}
}
});
}
I hope it helps.

I am using Xamarin Android, and for AppCompatActivity I also used this method which did not work for me.
SupportActionBar.SetHomeButtonEnabled(true);
but after finding on internet and I found another method, which worked for me, and showed the home navigation button.
SupportActionBar.SetDisplayHomeAsUpEnabled(true);

Control the Toolbar icon with NavigationDrawer

I'm currently using within my app the android.support.v7.widget.Toolbar and android.support.v4.widget.DrawerLayout. Everything is working right, but there is a slight thing I want to change its behaviour.
When I open the drawer, the whole drawer occupies the space of the Toolbar. It would be nice that the Toolbar stays on top, like in the Google Music app. How can I achieve that?
But the most important thing isn't the previous. At first, the icon which is loaded in the application is the three stripped one. I've realised that after opening the drawer, the icon changes to an arrow. And after loading a fragment, the arrow remains there as the Toolbar icon, even if I press back until the first screen. How could I avoid the arrow appearing from after opening the drawer? I'd want to change this icon manually, specially when I load lower level fragments.
Thanks for your help!

EDIT:
I have been able to modify a little bit my layout, so that the Toolbar stays on top of the rest screen (drawer and fragment). But I haven't been able to control the icon. When I open the drawer, the hamburger icon converts into the arrow. When I close the drawer, the arrow is converted into the hamburger. But when I press an option within the drawer, a new fragment is inflated and the hamburger icon is replaced by the arrow until the application is closed, so that the hamburger icon is never seen.
How can I adapt the icon behaviour so that it doesn't change from hamburger to arrow when I click over a drawer option?

now I try to do a similiar navigation drawer as you...
Basically respect me is that I had a diferent package for navigation drawer that I think so is different from your navigation drawer... My package is:
//From android studio
compile 'com.android.support:appcompat-v7:21.0.0'
I don't know if this can help you, but I follow this greatest tutorial and my navigation drawer work it's similar as you wish!
http://androideity.com/2013/12/16/android-navigation-drawer-parte-1/
http://androideity.com/2014/02/26/android-navigation-drawer-parte-2/
I wait that I help you! Good luck!
PD: If you have a problems with this tutorial or same advice me! :D

At first glance seems that you are setting new drawer listener whenever item is selected, precisely in this snippet:
private class DrawerItemClickListener implements OnItemClickListener {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
//selectItem(position);
final int thePos = position;
mDrawer.setDrawerListener( new DrawerLayout.SimpleDrawerListener(){
#Override
public void onDrawerClosed(View drawerView){
....
}
});
if(mDrawer.isDrawerOpen(GravityCompat.START))
mDrawer.closeDrawer(mDrawerRelativeLayout);
}
}
This snippet replaces ActionBarDrawerToggle (which implements DrawerListener as well), so no calls are made to ActionBarDrawerToggle which controls the icon.
How can I adapt the icon behaviour so that it doesn't change from hamburger to arrow when I click over a drawer option?
Relating to your previous statements, this sound vague to me. Why you'd be preventing this default behaviour? You can prevent morphing by not calling super calls in DrawerListener's methods.
