How can I change the ActionBar color of individual fragments in Android?

Is there any way to change the ActionBar color of fragments and change the title displayed in the ActionBar to the title of the menu option that was pressed?

If you are using AppCompat you always have to call getSupportActionBar()
Change Title :
getSupportActionBar().setTitle("Your Title");
Change Color :
getSupportActionBar().setBackgroundDrawable(new ColorDrawable(Color.YOUR_COLOR));
If in Fragment :
Change Title :
getActivity().getActionBar().setTitle("YOUR TITLE");
Change Color :
getActivity().getAcationBar().setBackgroundDrawable(new ColorDrawable(Color.YOUR_COLOR));
Hope this help you

This is the suggested answer written in java :
getActionBar().setTitle("Test");
getActionBar().setBackgroundDrawable(new ColorDrawable("COLOR"));

If you're using support libraries:
android.support.v7.app.ActionBar supportActionBar = ((AppCompatActivity) getActivity()).getSupportActionBar();
if (supportActionBar != null) {
supportActionBar.setTitle("My action bar title");
View view = new View(getContext());
view.setBackgroundColor(getResources().getColor(R.color.my_color));
supportActionBar.setBackgroundDrawable(view.getBackground());
}
Otherwise:
android.app.ActionBar actionBar = getActivity().getActionBar();
if (actionBar != null) {
actionBar.setTitle("My action bar title");
View view = new View(getContext());
view.setBackgroundColor(getResources().getColor(R.color.my_color));
actionBar.setBackgroundDrawable(view.getBackground());
}

getSupportActionBar setSubtitle only shows after activity recreation

I have a generic
MyActivity extends AppCompatActivity
I don't override the toolbar with a custom xml defined toolbar, just use the generated one Android provides.
I can set the title via your normal
getSupportActionBar().setTitle("foo");
but setting the subtitle via
getSupportActionBar().setSubtitle("bar");
doesn't set it. It remains blank. I'm doing this onCreate()
(I feel I've done this many times before with no fail)
Although I've noticed if I visit another activity, then return, the subtitle would then show... not on orientation change, not on recreate() but only when I'm returning from an activity.
I'm experiencing this on 5.0 and 7.0
For the time being I'll likely define my own Toolbar and move forward since that seems where most people have solutions for this same problem.
Relevant code:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_replenishment_list);
ButterKnife.bind(this);
MyApplication.getInstance().getComponent().inject(this);
setupUI();
}
private void setupUI() {
setupActionBar();
}
private void setupActionBar() {
ActionBar actionBar = getSupportActionBar();
if (actionBar != null) {
//TODO: not working unless activity is recreated...
// explore custom xml defined toolbar
//actionBar.setTitle("different title than what is defined in manifest"); <-- this does work, but not this
actionBar.setSubtitle(UserUtil.getFormattedFirstNameLastName(userService.getUserFromJWT(), this));
}
}

I have put the below code in my onCreate() method.
ActionBar actionBar = getActionBar();
if (actionBar==null) {
System.out.println("TEST NULL");
} else {
System.out.println("TEST NOT NULL");
}
The result is null. When I add the toolbar first it works fine.
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
ActionBar actionBar = getActionBar();
actionBar.setSubtitle("TESTING");
Your getSupportActionBar or getActionBar will return null if you didn't set toolbar to it. You need to set the toolbar to your action bar before using getSupportActionBar or getActionBar.

How to remove Action Bar and set the custom title of FragmentActivity of Sherlock

Hello I am using Sherlock library to achieve the Tabs. Here I am looking to remove the ActionBar at the top and set the custom title layout instead of it.
I achieved a functionality to add the Tabs but could not set the custom title over ActionBar. Any way to do this ?
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_pay_stub);
// adding action bar tabs to the activity
ActionBar mActionBar = getSupportActionBar();
Tab firstTab = mActionBar.newTab().setText(getString(R.string.paystub_current_tab)).setTabListener(this);
Tab secondTab = mActionBar.newTab().setText(getString(R.string.paystub_all_tab)).setTabListener(this);
// add the tabs to the action bar
mActionBar.addTab(firstTab);
mActionBar.addTab(secondTab);
// set the navigation mode the Action Bar Tabs
mActionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
}
Thanks in advance.

I resolved this by adding background color and icon of the ActionBar.
ActionBar actionBar = getSupportActionBar();
setTitle("");
actionBar.setIcon(R.drawable.headerlogo);
actionBar.setBackgroundDrawable(new ColorDrawable(Color.parseColor("#F4A401")));

Set actionbar icon for activity programatically?

I want to set the actionbar icon and title to be visible for an activity.
My app theme turns them off:
// styles.xml
<item name="android:displayOptions"></item>
In my activity:
public void onCreate() {
...
ActionBar actionBar = activity.getActionBar();
actionBar.setDisplayShowTitleEnabled(true);
actionBar.setIcon(R.drawable.ic_launcher);
actionBar.setHomeButtonEnabled(true);
actionBar.setDisplayHomeAsUpEnabled(true);
}
The title and up arrow appear. But I can't get the icon to appear. What am I doing wrong?

You are missing setDisplayShowHomeEnabled().

Start activity without ActionBar and add it in the onCreate event

I'm using the AppCompat/ActionBarCompat library and I need to create a custom ActionBar. I need to open the activity without an ActionBar and enable it only when I add the custom view. How can I do this?
PS: I need to define the activity to not use an ActionBar through the AndroidManifest.xml and my application minimum API level is 10.

.hide() the action bar and then .show() the action bar when your ready for it
import android.support.v7.app.ActionBar;
...
private ActionBar mActionbar;
...
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mActionbar = getSupportActionBar();
mActionbar.hide()
}
...
somewhere when something cool happens
mActionbar.show();
