Actual scenario.
I have an drawer menu with some menu options. Each menu click replace the fragment of the activity in which i want to show the logo with hamburger menu in home page fragment only and in rest of other pages i want hide it.
i tried like below
((AppCompatActivity) getActivity()).getSupportActionBar().setLogo(null);
to in rest of the fragments onResume() method
But in result menu logo gone when it call setLogo(null); but it was not come to previous state on home page even after setting setLogo(R.drawable.logo)
Advance thanks for helping..
To disable just call:
yourDrawerToggle.setDrawerIndicatorEnabled(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 want to change the Hamburger icon on Android ActionBar to Up arrow on button click, and also to change the Up arrow back to Hamburger icon on another button click event.
I have tried using ,
getSupportActionBar().setHomeButtonEnabled(true);
getSupportActionBar().setDisplayShowHomeEnabled(true);
However, none of them works. I can change the Hamburger icon to up arrow easily using,
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
But not the vice-versa.
Also, how do I override the home button control?
I mean when a certain layout is open, I want the up arrow to close that layout on click and not to call the navigation drawer.
Please help.
You could use the following piece of code:
ViewGroup home =(ViewGroup)findViewById(android.R.id.home).getParent();
// get the first child (up imageview)
((ImageView) home.getChildAt(0)).setImageResource(your image here);
Sorry, no privileges to comment so updating the answer. Well, since this is an imageView, I am assuming you could place an onClickListener and toggle between using the hamburger and the back arrow. This should be close to the material design's animated hamburger behavior.
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 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.
