Currently it just displays the name of the application and I want it to display something custom and be different for each screen in my app.
For example: my home screen could say 'page1' in the action bar while another activity that the app switches to could have 'page2' in that screens action bar.

The below code worked well for me inside the OnCreate
method:
getSupportActionBar().setTitle("Text to display");

If using a fragment, the best way is just to add a label element inside the fragment.xml
(not manifest)
Example:
android:label="Your text.."

In onCreateView add this:
(activity as AppCompatActivity).supportActionBar?.title ="My APP Title"

if u r using navigation bar to change fragment then u can add change it where u r changing Fragment like below example :
public boolean onNavigationItemSelected(@NonNull MenuItem item) {
switch (item.getItemId()) {
case R.id.clientsidedrawer:
// Toast.makeText(getApplicationContext(),"Client selected",Toast.LENGTH_SHORT).show();
getSupportFragmentManager().beginTransaction().replace(R.id.fragment_container, new clients_fragment()).commit();
break;
case R.id.adddatasidedrawer:
getSupportActionBar().setTitle("Add Client");
getSupportFragmentManager().beginTransaction().replace(R.id.fragment_container, new addclient_fragment()).commit();
break;
case R.id.editid:
getSupportActionBar().setTitle("Edit Clients");
getSupportFragmentManager().beginTransaction().replace(R.id.fragment_container, new Editclient()).commit();
break;
case R.id.taskid:
getSupportActionBar().setTitle("Task manager");
getSupportFragmentManager().beginTransaction().replace(R.id.fragment_container,new Taskmanager()).commit();
break;
if u r using simple activity then just call :
getSupportActionBar().setTitle("Contact Us");
to change actionbar/toolbar color in activity use :
getSupportActionBar().setBackgroundDrawable(new ColorDrawable(Color.parseColor("#06023b")));
to set gradient to actionbar first create gradient : Example directry created > R.drawable.gradient_contactus
<?xml version="1.0" encoding="utf-8"?>
<shape
xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle"
>
<gradient
android:angle="90"
android:startColor="#2980b9"
android:centerColor="#6dd5fa"
android:endColor="#2980b9">
</gradient>
</shape>
and then set it like this :
getSupportActionBar().setBackgroundDrawable(getResources().getDrawable(R.drawable.gradient_contactus));

Kotlin
You can do it programmatically in Kotlin this way. You just ignore it if "supportActionBar" is null:
supportActionBar?.setTitle(R.string.my_text)
supportActionBar?.title = "My text"
Or this way. It throws an exception if "supportActionBar" is null.
supportActionBar!!.setTitle(R.string.my_text)
supportActionBar!!.title = "My text"

For future developers that are using AndroidX and the navigation architectural component.
Instead of setting the toolbar title using one of the solutions above, which can be very painful if you want to set it dynamically on a back stack change, you can set a placeholder for the title of the fragment in the navigation graph like the following:
<fragment
android:id="@+id/some_fragment"
android:name="package.SomeFragment"
android:label="Hello {placeholder}"
tools:layout="@layout/fragment_some">
<argument
android:name="placeholder"
app:argType="string" />
</fragment>
The placeholder value has to be provided using the FragmentDirections
(via the action method).
It is then replaced in the title and show like Hello World
(when placeholder = "World"
).

The easiest way is to call this.setTitle("...")
if you are in the activity.
And if you are in a fragment, just call getActivity().setTitle("...")
;
This way will let you change the title anytime, no need to call it before setContentView(R.layout.activity_test)
;

The Easiest way to change the action bar name is to go to the AndroidManifest.xml and type this code.
<activity android:name=".MainActivity"
android:label="Your Label> </activity>

ActionBar ab = getActionBar();
TextView tv = new TextView(getApplicationContext());
LayoutParams lp = new RelativeLayout.LayoutParams(
LayoutParams.MATCH_PARENT, // Width of TextView
LayoutParams.WRAP_CONTENT);
tv.setLayoutParams(lp);
tv.setTextColor(Color.RED);
ab.setCustomView(tv);

Inside Activity.onCreate() callback or in the another place where you need to change title:
getSupportActionBar().setTitle("Whatever title");

Little bit older but had the same problem. I did it like this:
strings.xml
<string name="title_awesome_app">My Awesome App</string>
and make sure you set this in your AndroidManifest.xml:
<activity
...
android:label="@string/title_awesome_app" >
...
</activity>
it's easy and you don't have to worry about null-references and other stuff.

We can change the ActionBar title in one of two ways:
In the Manifest: in the manifest file, set the label of each Activity.
android:label="@string/TitleWhichYouWantToDisplay"
In code: in code, call the setTitle() method with a String or the id of String as the argument.
public class MainActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
setTitle(R.string.TitleWhichYouWantToDisplay);
// OR You can also use the line below
// setTitle("MyTitle")
setContentView(R.layout.activity_main);
}
}

FYI, ActionBar was introduced in API Level 11. ActionBar is a window feature at the top of the Activity that may display the activity title, navigation modes, and other interactive items like search.
I exactly remember about customizing title bar and making it consistent through the application. So I can make a comparison with the earlier days and can list some of the advantages of using ActionBar:
For example:
getActionBar().setTitle("Hello world App");
getSupportActionBar().setTitle("Hello world App"); // provide compatibility to all the versions
For example:
@Override
public void setActionBar(String heading) {
// TODO Auto-generated method stub
com.actionbarsherlock.app.ActionBar actionBar = getSupportActionBar();
actionBar.setHomeButtonEnabled(true);
actionBar.setDisplayHomeAsUpEnabled(false);
actionBar.setDisplayShowHomeEnabled(false);
actionBar.setBackgroundDrawable(new ColorDrawable(getResources().getColor(R.color.title_bar_gray)));
actionBar.setTitle(heading);
actionBar.show();
}
The ActionBar provides you with basic and familiar looks, navigation modes and other quick actions to perform. But that doesn't mean it looks the same in every app. You can customize it as per your UI and design requirements. You just have to define and write styles and themes.
Read more at: Styling the Action Bar
And if you want to generate styles for ActionBar then this Style Generator tool can help you out.
=================================================================================
you can Change the Title of each screen (i.e. Activity) by setting their Android:label
<activity android:name=".Hello_World"
android:label="This is the Hello World Application">
</activity>
But if you want to Customize title-bar in your own way, i.e. Want to put Image icon and custom-text
, then the following code works for me:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"/>
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="400dp"
android:layout_height="fill_parent"
android:orientation="horizontal">
<ImageView android:id="@+id/ImageView01"
android:layout_width="57dp"
android:layout_height="wrap_content"
android:background="@drawable/icon1"/>
<TextView
android:id="@+id/myTitle"
android:text="This is my new title"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:textColor="@color/titletextcolor"
/>
</LinearLayout>
public class TitleBar extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
final boolean customTitleSupported =
requestWindowFeature(Window.FEATURE_CUSTOM_TITLE);
setContentView(R.layout.main);
if (customTitleSupported) {
getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE,
R.layout.titlebar);
}
final TextView myTitleText = (TextView) findViewById(R.id.myTitle);
if (myTitleText != null) {
myTitleText.setText("NEW TITLE");
// user can also set color using "Color" and then
// "Color value constant"
// myTitleText.setBackgroundColor(Color.GREEN);
}
}
}
The strings.xml file is defined under the values
folder.
<?xml version="1.0" encoding="utf-8"?>
<resources>
<string name="hello">Hello World, Set_Text_TitleBar!</string>
<string name="app_name">Set_Text_TitleBar</string>
<color name="titlebackgroundcolor">#3232CD</color>
<color name="titletextcolor">#FFFF00</color>
</resources>

You can define your title programatically using setTitle
within your Activity
, this method can accept either a String
or an ID defined in your values/strings.xml
file. Example:
public class YourActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
setTitle(R.string.your_title);
setContentView(R.layout.main);
}
}

try do this...
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
this.setTitle(String.format(your_format_string, your_personal_text_to_display));
setContentView(R.layout.your_layout);
...
...
}
it works for me

You can define the label for each activity in your manifest file.
A normal definition of a activity looks like this:
<activity
android:name=".ui.myactivity"
android:label="@string/Title Text" />
Where title text should be replaced by the id of a string resource for this activity.
You can also set the title text from code if you want to set it dynamically.
setTitle(address.getCity());
with this line the title is set to the city of a specific adress in the oncreate method of my activity.
