I am having difficulties trying to remove the back/home button from the action bar.
getActionBar().setDisplayShowHomeEnabled(false); //disable back button
getActionBar().setHomeButtonEnabled(false);
In a older android phone, the back button is removed with these two code lines. However with the nexus 4, the back button still appears but is just disabled. Also I am just adding a menu item on the right that behaves like the back/home button replacing the back/home button. What am I missing?
Use getActionBar().setDisplayHomeAsUpEnabled(false) to remove the home button from the action bar.
If you're on API level 14 or above and are not using ActionbarSherlock, this code in onCreateOptionsMenu will disable the up button, remove the left caret, and remove the icon:
ActionBar actionBar = getActionBar();
if (actionBar != null) {
actionBar.setHomeButtonEnabled(false); // disable the button
actionBar.setDisplayHomeAsUpEnabled(false); // remove the left caret
actionBar.setDisplayShowHomeEnabled(false); // remove the icon
}

ElectronicGeeks answer is correct.
For API lower than 11, Use:
getSupportActionBar().setDisplayHomeAsUpEnabled(false);
To control the up affordance, use setDisplayHomeAsUpEnabled().
None of the suggested solutions works for me.
But this one does:
// Hide the back button
mActionBar.setHomeAsUpIndicator(null);
It is a kind of a hack (last resort solution), though, so showing the action bar again means setting its icon back again.
This worked for me :)
ActionBar actionBar = getSupportActionBar();
actionBar.setDisplayHomeAsUpEnabled(false);
For Kotlin;
(activity as AppCompatActivity).supportActionBar?.setDisplayHomeAsUpEnable(false)
In the case where you have used toolbar as Action bar:-
Toolbar toolbar = findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
Use the below code to hide the navigation button:-
toolbar.setNavigationIcon(null);
This code work for me
For remove navigation bar
getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_HIDE_NAVIGATION);
For remove status bar
getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_FULLSCREEN);
ฺBut above code, it show again when you touch on screen, so if you want static state, combine this code.
getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_IMMERSIVE);
You can use this code :
toggle.setDrawerIndicatorEnabled(false);
Works great for me.

When I use to change Hamburger Icon to Back Icon while add a new fragment it's Perfectly working. Here is my code
supportActionBar!!.setDisplayHomeAsUpEnabled(true)
supportActionBar!!.setDisplayShowHomeEnabled(true)
But when I press back button and close the fragment then it not change to hamburger icon
supportActionBar!!.setDisplayHomeAsUpEnabled(false)
supportActionBar!!.setDisplayShowHomeEnabled(false)
NOTE: I dont have drawer layout. I use this library: yarolegovich/SlidingRootNav
This is expected behaviour, it won't automatically change when you are doing:
actionBar.setDisplayHomeAsUpEnabled(true);
One solution would be to handle it for yourself. Just change the icon manually
actionBar.setDisplayHomeAsUpEnabled(true);
actionBar.setHomeAsUpIndicator(R.drawable.back);
and on back pressed, change it to hamburger icon:
actionBar.setDisplayHomeAsUpEnabled(true);
actionBar.setHomeAsUpIndicator(R.drawable.hamburger_icon);
Hope this helps. Cheers.
I have created custom action mode which visible on long click on list item . There is default back/up button visible in actionMode.
Without change in style.xml , it's possible to remove default action mode back/up button from fragment/activity class.
Kindly help.
Try this,
getActionBar().setDisplayHomeAsUpEnabled(false);
OR
getSupportActionBar().setDisplayHomeAsUpEnabled(false);
this may helps you.
Use the method: getActionBar().setDisplayHomeAsUpEnabled(false) to remove the home button from the action bar.
Example:
ActionBar actionBar = getActionBar();
if (actionBar != null) {
actionBar.setHomeButtonEnabled(false); // disable the button
actionBar.setDisplayHomeAsUpEnabled(false); // remove the left caret
actionBar.setDisplayShowHomeEnabled(false); // remove the icon
}
You can remove action button home up enabled through ::
if you are using support v7 lib then
getSupportActionBar().setDisplayHomeAsUpEnabled(false);
else
getActionBar().setDisplayHomeAsUpEnabled(false);
I created two blank activities in android studio and it looks like it adds back arrow by default. My MainActivity is parent ofResultActivity. I want to maintain this hierarchy but want to get rid of back arrow.
If you're on API level 14 or above and are not using ActionbarSherlock, this code in onCreateOptionsMenu should disable the up button;
ActionBar actionBar = getActionBar();
if (actionBar != null) {
actionBar.setHomeButtonEnabled(false); // Disable the button
actionBar.setDisplayHomeAsUpEnabled(false); // Remove the left caret
actionBar.setDisplayShowHomeEnabled(false); // Remove the icon
}
If you're using a support lib such as ActionbarSherlock, then use;
getSupportActionBar().setHomeButtonEnabled(false); // Disable the button
getSupportActionBar().setDisplayHomeAsUpEnabled(false); // Remove the left caret
getSupportActionBar().setDisplayShowHomeEnabled(false); // Remove the icon
getActionBar().setDisplayHomeAsUpEnabled(false);
I know this is an old question but I came across this now and had to take some additional action to remove the back arrow.
So in addition to this piece of code as indicated the correct answer
getActionBar().setDisplayHomeAsUpEnabled(false);
you will also need to remove the parent-child relationship in the AndroidManifest.xml file . Your activity should not have the following entry
android:parentActivityName
Might help someone else who stumbles across this one.
I need to remove the back arrow and keep only the home icon in action bar sherlock library. I set getSupportActionBar().setDisplayHomeAsUpEnabled() to false but it disabled action bar button.
Maybe you forgot to set the home button itself as enabled?
Try this instead:
// Hide the ActionBar's up button
getSupportActionBar().setDisplayHomeAsUpEnabled(false);
getSupportActionBar().setHomeButtonEnabled(true);
I am using ActionBarSherlock on my simple app and would like to hide the HOME button if the user is on the home/main activity. I understand how to do so with the setHomeButtonEnabled(false), however, I am extending a class that contains my navigation and has setHomeButtonEnabled(true) and I cannot seem to overwrite that setting in my main activity.
Thanks to #andy I am able to get rid of the icon, however, I cannot get rid of the < arrow. Any ideas?
Thanks for any help.
With ActionBarSherlock just put this in your home/main activity onCreate() method:
final ActionBar actionBar = getSupportActionBar();
actionBar.setDisplayShowHomeEnabled(false);
The only way I have found to do this is to not have this set on your baseActivity:
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
and then set it as you will for each activity that requires the menu:
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
or
getSupportActionBar().setDisplayHomeAsUpEnabled(false);
Get the home button view and apply this
mHomeButton.setVisibility(View.INVISIBLE);
