Question

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.

Was it helpful?

Solution

Update: Latest ActionBar (Title) pattern:

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:

  1. It offers your users a familiar interface across applications that the system gracefully adapts for different screen configurations.
  2. Developers don't need to write much code for displaying the Activity Title, icons and navigation modes because ActionBar is already ready with top level abstraction.

For example:

enter image description here

enter image description here

=> Normal way,

getActionBar().setTitle("Hello world App");   
getSupportActionBar().setTitle("Hello world App");  // provide compatibility to all the versions

=> Customizing Action Bar,

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();

}

Styling the Action Bar:

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.

Old: Earlier days:

=> Normal way,

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>

=> Custom - Title - bar


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:

main.xml

<?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"/>

titlebar.xml

<?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>

TitleBar.java

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);
        }
    }
}

strings.xml

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>

OTHER TIPS

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.

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);

    }
}

We can change the ActionBar title in one of two ways:

  1. In the Manifest: in the manifest file, set the label of each Activity.

    android:label="@string/TitleWhichYouWantToDisplay"
    
  2. 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);
    
        }
    }
    

Inside Activity.onCreate() callback or in the another place where you need to change title:

getSupportActionBar().setTitle("Whatever title");

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

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.

getActionBar().setTitle("edit your text"); 

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>

You just add this code in the onCreate method.

setTitle("new title");
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);

The best way to change the action bar name is to go to the AndroidManifest.xml and type this code.

<activity android:name=".YourActivity"
        android:label="NameYouWantToDisplay> </activity>

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);

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").
