getActionBar().setHomeAsUpIndicator() Breaking Navigation Drawer "Hamburger" Animation

In my application, I'm using a Navigation Drawer. I have given each item in the Navigation Drawer a different Icon for opening the Nav Drawer.
When I initially start the app, the drawer icon for the first fragment animates like normal. But when I click on another Nav Drawer Item, the animations break.
In my MainActivity, I have this code for toggling the nav drawer:
getActionBar().setDisplayHomeAsUpEnabled(true);
getActionBar().setHomeButtonEnabled(true);
mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout,
R.drawable.ab_mytasks, R.string.drawer_open,
R.string.drawer_close) {
public void onDrawerClosed(View view) {
getActionBar().setTitle(mTitle);
invalidateOptionsMenu(); // creates call to
// onPrepareOptionsMenu()
}
public void onDrawerOpened(View drawerView) {
getActionBar().setTitle(mDrawerTitle);
invalidateOptionsMenu(); // creates call to
// onPrepareOptionsMenu()
}
};
mDrawerLayout.setDrawerListener(mDrawerToggle);
mDrawerToggle.syncState();
Then in each of my fragments, I have this code for setting the custom icon:
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setHasOptionsMenu(true);
final ActionBar actionBar = getActivity().getActionBar();
actionBar.setDisplayShowTitleEnabled(false);
actionBar.setHomeAsUpIndicator(R.drawable.ab_mytasks);
}
I have tried putting in the same mDrawerToggle method as in my MainActivity into my fragments. But the app crashes when I use getActivity().invalidateOptionsMenu().
Here is an image representation of my problem:
1 = Animation works as normal
2 = Selected another fragment from Nav Drawer
3 = Original Fragment icon animation is broken

When you change the icon (setHomeAsUpIndicator) you will no longer get an animation.

Change Navigation Drawer homeAsUpIndicator with ActionBarDrawerToggle and appcompat v7

I'm trying to change my action bar's home as up indicator. Right now it shows an arrow (when opened) and 3 stripes (when closed):
I want to replace this arrow with a custom drawable. The code below doesn't works:
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setHomeButtonEnabled(true);
getSupportActionBar().setLogo(getResources().getDrawable(R.drawable.actionbar_logo));
getSupportActionBar().setDisplayUseLogoEnabled(true);
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
mDrawerToggle = new ActionBarDrawerToggle(
this, /* host Activity */
mDrawerLayout, /* DrawerLayout object */
R.string.app_name, /* "open drawer" description for accessibility */
R.string.app_name /* "close drawer" description for accessibility */
) {
public void onDrawerClosed(View view) {
//getActionBar().setTitle(mTitle);
//invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
}
public void onDrawerOpened(View drawerView) {
//getActionBar().setTitle(mDrawerTitle);
//invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
}
};
mDrawerToggle.setHomeAsUpIndicator(getResources().getDrawable(R.drawable.actionbar_logo));
mDrawerLayout.setDrawerListener(mDrawerToggle);
If I use <item name="displayOptions">useLogo|showHome|showTitle</item> at the style, it shows my custom drawable besides the original homeAsUpIndicator, while what I want is to replace it
How can I achieve this? Thanks!

Deprecated ActionBarDrawerToggle

I was trying to implement the android.support.v4.app.ActionBarDrawerToggle in my app; since this class is deprecated
This class is deprecated. Please use ActionBarDrawerToggle in
support-v7-appcompat.
I've switched to android.support.v7.app.ActionBarDrawerToggle.
Before I could call the constructor in this way:
mDrawerToggle = new ActionBarDrawerToggle(
this, /* host Activity */
mDrawerLayout, /* DrawerLayout object */
R.drawable.ic_drawer, /* nav drawer image to replace 'Up' caret */
R.string.drawer_open, /* "open drawer" description for accessibility */
R.string.drawer_close /* "close drawer" description for accessibility */
){
public void onDrawerClosed(View view) {
getActionBar().setTitle(mTitle);
invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
}
public void onDrawerOpened(View drawerView) {
getActionBar().setTitle(mDrawerTitle);
invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
}
};
but after I've switched to the newer v7 support library, I receive the error
"ActionBarDrawerToggle() in ActionBarDrawerToggle cannot be applied to:
toolbar: android.support.v7.widget.Toolbar
Actual arguments: R.drawable.ic_drawer (int)"
Apparently I am not introducing a proper Toolbar into the constructor, but I'm not sure to understand the difference between the two conflicting arguments. How do I get the required toolbar?

I solved my problem by importing the newer android.support.v7.app.ActionBarDrawerToggle and by using the RecyclerView instead of the ListView as shown in this example: How to make Material Design Navigation Drawer With Header View:
private ActionBarDrawerToggle mDrawerToggle;
//... ...
mDrawerToggle = new ActionBarDrawerToggle(
this,
mDrawerLayout,
toolbar,
R.string.drawer_open, R.string.drawer_close){
#Override
public void onDrawerOpened(View drawerView) {
super.onDrawerOpened(drawerView);
// code here will execute once the drawer is opened
getSupportActionBar().setTitle(mTitle);
invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
}
#Override
public void onDrawerClosed(View drawerView) {
super.onDrawerClosed(drawerView);
// Code here will execute once drawer is closed
getSupportActionBar().setTitle(mDrawerTitle);
invalidateOptionsMenu();
};

How to add "menu" indicator next to Action Bar's app icon?

At least Gmail and Youtube Android apps use a side menu (navigation drawer?) that opens by swiping, or by clicking the app icon (home button):
Is the menu indicator / icon in the screenshot above a ready-made part of Android SDK? (Or a custom icon Google uses in their apps?) In any case, what's the easiest way to get your home button to look like that, i.e., like it opens a menu?
(targetSdkVersion 18; minSdkVersion 14)
Resolution
Finally got it working. What was missing for me was 1) the actual icon and 2) deferred call to syncState() on the ActionBarDrawerToggle.

To create similar implementation / look in your application you should use ActionBarDrawerToggle and set your custom icon as indicator next to ActionBar home button. For example :
import android.app.ActionBar;
import android.support.v4.app.ActionBarDrawerToggle;
import android.support.v4.widget.DrawerLayout;
private void setUpDrawerToggle(){
ActionBar actionBar = getActionBar();
actionBar.setDisplayHomeAsUpEnabled(true);
actionBar.setHomeButtonEnabled(true);
// ActionBarDrawerToggle ties together the the proper interactions
// between the navigation drawer and the action bar app icon.
mDrawerToggle = new ActionBarDrawerToggle(
this, /* host Activity */
mDrawerLayout, /* DrawerLayout object */
R.drawable.ic_drawer, /* nav drawer image to replace 'Up' caret */
R.string.navigation_drawer_open, /* "open drawer" description for accessibility */
R.string.navigation_drawer_close /* "close drawer" description for accessibility */
) {
#Override
public void onDrawerClosed(View drawerView) {
invalidateOptionsMenu(); // calls onPrepareOptionsMenu()
}
#Override
public void onDrawerOpened(View drawerView) {
invalidateOptionsMenu(); // calls onPrepareOptionsMenu()
}
};
// Defer code dependent on restoration of previous instance state.
// NB: required for the drawer indicator to show up!
mDrawerLayout.post(new Runnable() {
#Override
public void run() {
mDrawerToggle.syncState();
}
});
mDrawerLayout.setDrawerListener(mDrawerToggle);
}
Where R.drawable.ic_drawer is actually the icon to use as indicator. You can find it in Android Asset Studio; see Navigation Drawer Indicator.

Creating a Navigation Drawer

Android-Developer and HpTerm helped me in the right rirection, by
Pointing out this is indeed NavigationDrawer specific (which I was already using as in Google's example)
Telling where to find the ic_drawer.png icon (→ Android Asset Studio)
Now, unfortunately, creating ActionBarDrawerToggle like below seems not to be enough.
At least on my Nexus 7 (API 18) test device.
drawerToggle = new ActionBarDrawerToggle(this,
drawerLayout,
R.drawable.ic_navigation_drawer,
R.string.side_menu_open,
R.string.side_menu_closed) {
// ...
};
Partial solution (API level 18+)
I found one way to make the indicator show up though: setHomeAsUpIndicator(). The downside: that method was added in API level 18.
#Override
protected void onCreate(Bundle savedInstanceState) {
// ...
getActionBar().setDisplayHomeAsUpEnabled(true); // also required
if (Build.VERSION.SDK_INT >= 18) {
getActionBar().setHomeAsUpIndicator(
getResources().getDrawable(R.drawable.ic_navigation_drawer));
}
}
So now the question remains: how to make this work (in my case) for API levels 14 through 17?
I verified on a 4.1.2 (API 16) device that the ic_drawer icon does not show up. With setDisplayHomeAsUpEnabled(true) I get the normal "home" icon (small arrow pointing left) and without it, the space left to my app icon remains blank.
Final solution
Got it working using the edited version of Android-Developer's answer.
Quite curiously, what was missing from my ActionBarDrawerToggle initialisation code was this:
// Defer code dependent on restoration of previous instance state.
drawerLayout.post(new Runnable() {
#Override
public void run() {
mDrawerToggle.syncState();
}
});
With that included, calling setHomeAsUpIndicator() is not needed.

The keyword here is NavigationDrawer; there's a full working code example on the Android developer site.
READ THE END OF THE LINK GIVEN : Open and Close with the App Icon
The following code is copied from there
public class MainActivity extends Activity {
private DrawerLayout mDrawerLayout;
private ActionBarDrawerToggle mDrawerToggle;
...
public void onCreate(Bundle savedInstanceState) {
...
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
mDrawerToggle = new ActionBarDrawerToggle(
this, /* host Activity */
mDrawerLayout, /* DrawerLayout object */
R.drawable.ic_drawer, /* nav drawer icon to replace 'Up' caret */
R.string.drawer_open, /* "open drawer" description */
R.string.drawer_close /* "close drawer" description */
) {
/** Called when a drawer has settled in a completely closed state. */
public void onDrawerClosed(View view) {
getActionBar().setTitle(mTitle);
}
/** Called when a drawer has settled in a completely open state. */
public void onDrawerOpened(View drawerView) {
getActionBar().setTitle(mDrawerTitle);
}
};
// Set the drawer toggle as the DrawerListener
mDrawerLayout.setDrawerListener(mDrawerToggle);
getActionBar().setDisplayHomeAsUpEnabled(true);
getActionBar().setHomeButtonEnabled(true);
}
#Override
protected void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
// Sync the toggle state after onRestoreInstanceState has occurred.
mDrawerToggle.syncState();
}
#Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
mDrawerToggle.onConfigurationChanged(newConfig);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Pass the event to ActionBarDrawerToggle, if it returns
// true, then it has handled the app icon touch event
if (mDrawerToggle.onOptionsItemSelected(item)) {
return true;
}
// Handle your other action bar items...
return super.onOptionsItemSelected(item);
}
...
}
Some files are available as download and the small 3 lines with the animation effect is fully exemplified.
You have to copy thoses files in the corresponding drawable folder. Depending on the theme you use, dark or light you have a different set of icons.
In my case I simply copied the drawer_shadow.9.png and ic_drawer.png in the drawable folder and followed the example and everything works just fine.
The icons are available in the link I provided, but they are NOT in the "Action Bar Icon Pack", they are in the sample app in the corresponding res/drawable folders.

Toggle DrawerLayout With Title Only (NO App Icon)?

I have an activity with a DrawerLayout. I can open the drawer two different ways...by swiping from the left area of the screen towards the right and by clicking the app title. I DO NOT have an app icon displayed, only a title. I've implemented this exactly as recommended by Google here: Creating a Navigation Drawer: Open and Close with the App Icon
Everything is functional as far as opening and closing the drawer itself. However, it does not display the standard DrawerLayout icon that is suppose to be used. Instead I get the regular up caret (looks like a less than sign).
As soon as I add the app icon back to the ActionBar it begins to work as expected. The Drawer layout icon displays and animates when the drawer is opened or closed. I've tried removing the app icon both in my styles XML file and programmatically.
Is there a way to get the DrawerLayout icon working WITHOUT the app icon???
UPDATE: I've found a work around, but it's a hack more so than a solution. I simply created a 1x1 pixel transparent PNG (blank.png) and set it as my app icon in my styles.xml file. Below is all relative code:
styles.xml
<style name="MyCustomTheme" parent="android:Theme.Holo.Light.DarkActionBar">
<item name="android:actionBarStyle">#style/MyCustomActionBar</item>
<item name="android:icon">#drawable/blank</item>
</style>
<style name="MyCustomActionBar" parent="#android:style/Widget.Holo.ActionBar">
<item name="android:displayOptions">showHome|showTitle|homeAsUp</item>
</style>
MainActivity -> onCreate()
this.navDrawerToggle = new ActionBarDrawerToggle
(
this,
this.navDrawerLayout,
R.drawable.icon_nav_drawer,
R.string.nav_drawer_open,
R.string.nav_drawer_closed
)
{
public void onDrawerClosed(View view) {}
public void onDrawerOpened(View drawerView) {}
};
MainActivity -> onPostCreate()
super.onPostCreate(savedInstanceState);
this.navDrawerToggle.syncState();
MainActivity -> onResume()
this.navDrawer.setOnItemClickListener(new DrawerItemClickListener());
this.navDrawerLayout.setDrawerListener(this.navDrawerToggle);
MainActivity -> onPause()
this.navDrawer.setOnItemClickListener(null);
this.navDrawerLayout.setDrawerListener(null);
MainActivity -> onConfigurationChanged(Configuration newConfig)
super.onConfigurationChanged(newConfig);
navDrawerToggle.onConfigurationChanged(newConfig);
MainActivity -> onOptionsItemSelected(MenuItem item)
if (this.navDrawerToggle.onOptionsItemSelected(item)) {return true;}
else
{
// A bunch of item click handling happens here...
return true;
}

I was curious about this so I tried it with the sample for the DrawerLayout and it worked fine. Also, it seems like you have to use your own drawer icon drawable, it's recommended anyways. You can download the default assets from this site Creating a Navigation Drawer and put them in their respective drawable resource folder.
Here's what worked for me:
ActionBar actionBar = getActionBar();
// Let's get rid of the app icon here
actionBar.setIcon(null);
actionBar.setTitle("App Name");
// Setting these 3 options allows us to show the title as well as a "Home" elements
// "Home" elements include the Up and/or Drawer icon. The DISPLAY_HOME_AS_UP will enable
// and show the Drawer icon, we'll be "replacing" the "up" button with the drawer icon below
actionBar.setDisplayOptions(ActionBar.DISPLAY_SHOW_TITLE
| ActionBar.DISPLAY_SHOW_HOME
| ActionBar.DISPLAY_HOME_AS_UP);
// Get a reference of the DrawerLayout
DrawerLayout drawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
drawerLayout.setDrawerListener(drawerToggle);
// Setting ActionBarDrawerToggle will allow you to set the drawables for the drawer
// (this will also give you the nice/smooth animation) as well as allow you to do some
// other things depending on the events: onDrawerClosed & onDrawerOpened.
ActionBarDrawerToggle drawerToggle = new ActionBarDrawerToggle(
this, /* host Activity */
drawerLayout, /* DrawerLayout object */
R.drawable.ic_drawer, /* nav drawer image to replace 'Up' caret */
R.string.drawer_open, /* "open drawer" description for accessibility */
R.string.drawer_closed /* "close drawer" description for accessibility */
) {
public void onDrawerClosed(View view) {
actionBar.setTitle("Closed...");
invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
}
public void onDrawerOpened(View drawerView) {
actionBar.setTitle("Open...");
invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
}
};
// Set a listener to be notified of drawer events.
drawerLayout.setDrawerListener(drawerToggle);
UPDATE: It seems like the android:displayOptions on the ActionBar style are not being accounted for. Use actionBar.setDisplayOptions(int options) instead.

getActionBar().setIcon(android.R.color.transparent);
This worked for me..... ;)

After setting the drawer toggle you need to call the following method:
mDrawerToggle.syncState();
so your code would look like this:
mDrawerToggle = new ActionBarDrawerToggle(
this, /* host Activity */
mDrawerLayout, /* DrawerLayout object */
R.drawable.ic_drawer, /* nav drawer image to replace 'Up' caret */
R.string.drawer_open, /* "open drawer" description for accessibility */
R.string.drawer_close /* "close drawer" description for accessibility */
) {
public void onDrawerClosed(View view) {
actionBar.setTitle(mTitle);
invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
}
public void onDrawerOpened(View drawerView) {
actionBar.setTitle("Preview Mode");
invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
}
};
mDrawerToggle.syncState();
mDrawerLayout.setDrawerListener(mDrawerToggle);
