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;
}
Solution

  • getActionBar().setIcon(android.R.color.transparent);

    This worked for me..... ;)
