Customizing ActionBarSherlock - disabling back/home button - android

I'm using custom layout for an action bar, using the following code:
getSupportActionBar().setDisplayShowTitleEnabled(false);
getSupportActionBar().setDisplayHomeAsUpEnabled(false);
getSupportActionBar().setHomeButtonEnabled(false);
getSupportActionBar().setIcon(android.R.color.transparent);
getSupportActionBar().setDisplayShowCustomEnabled(true);
getSupportActionBar().setCustomView(R.layout.custom_action_bar);
However, it keeps showing some fragment of the action bar which is not the custom action bar I've created:
How do I fix this?


It looks like this was enough to get it working (instead of all the lines I quoted in the question details):
getSupportActionBar().setDisplayOptions(ActionBar.DISPLAY_SHOW_CUSTOM);
getSupportActionBar().setCustomView(R.layout.custom_action_bar);

Action Bar with custom font and back arrow

I'm trying to customize the font in one activity action bar. I managed to do it by using this code during activity's onCreate:
if(getSupportActionBar()!=null){
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setDisplayShowHomeEnabled(true);
getSupportActionBar().setDisplayOptions(ActionBar.DISPLAY_SHOW_CUSTOM);
getSupportActionBar().setCustomView(R.layout.secondary_toolbar);
TextView actionBarTitle = getSupportActionBar().getCustomView().findViewById(R.id.toolbar_title);
actionBarTitle.setText(R.string.new_payment_method);
}
The problem is that if I change the toolbar to a custom layout, the code lines which enables the arrow to let the activity to navigate to the previous activity doesn't work anymore. I'm stuck finding a way to modify the font in the action bar and showing the back arrow which allows me to navigate back, at the same time.

Android Toolbar set title explanation

I have my app Toolbar here:
toolbar = (Toolbar) findViewById(R.id.app_bar);
setSupportActionBar(toolbar);
When i want to set the screen title, i have to do the following:
ActionBar bar = getSupportActionBar();
if (bar != null) {
bar.setTitle(SCREEN_TITLE);
}
My questions is, why when calling the toolbar.setTitle() is not working. But instead i need to get the action bar first and then i can set the title?
P.S. In the other hand, I can set the Toolbar icon normally without getting the action bar as so:
toolbar.setNavigationIcon(R.drawable.ic_arrow_back_white);

A Toolbar is a generalization of action bars for use within application layouts.
Unlike Action bar , toolbar is not part of window decor.You defines it and place it just like any other widget...therefor you have freedom to place it anywhere in the parent layout.
You have freedom to put any widget inside toolbar.
You can define multiple toolbars.
Toolbar may be placed at any arbitrary level of nesting within a view hierarchy. An application may choose to designate a Toolbar as the action bar for an Activity using the setActionBar() method.
As Toolbar is generalization of ActionBar. you have to first set Toolbar as ActionBar then you can use all method of ActionBar.
EDIT:
Here is Link that explains Toolbar concept.
Here is bug link reported in android issues: In issue they suggest that Once you call setSupportActionBar(Toolbar), the Action Bar is then responsible for handling the title, meaning that you need to call getSupportActionBar().setTitle(...) to set a custom title. It also gives explanation about why toolbar.setNavigationIcon(R.drawable.ic_arrow_back_white); works.
I hope it helps!

Material action bar in eclipse

How to create android material design action bar in eclipse

For navigation drawer you just need to update android-support library.
For material action bar see Toolbar
Sample code you can see here this is more about navigation drawer but it also contains code for toolbar

Navigation Drawer icon not shown

I am using Custom Action bar. For which the code i am using is -
getActionBar().setDisplayOptions(ActionBar.DISPLAY_SHOW_CUSTOM);
getActionBar().setCustomView(R.layout.custom_home_action_bar);
ActionBar bar = getActionBar();
bar.setBackgroundDrawable(new ColorDrawable(getResources().getColor(
R.color.color_dark_blue)));
but when I use this code to customise my action bar, navigation drawer icon is not shown. When I comment these lines it is perfectly shown but then I cannot customise my action bar.How can i achieve both?
Thanks in advance

I got the solution. I used
getActionBar().setDisplayOptions(ActionBar.DISPLAY_SHOW_CUSTOM | ActionBar.DISPLAY_SHOW_HOME);
instead of
getActionBar().setDisplayOptions(ActionBar.DISPLAY_SHOW_CUSTOM);

android: how to remove the back/home button in the action bar

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.
