Answer 1

There are two ways to change title bar for your activity:

1. Design time (that is, change title in AndroidManifest.xml file).
2. By coding (that is, you can code to change the activity title).

Example for 1st:

you can Change the Title of each screen (ie Activity) by setting their Android:label inside the AndroidManifest.xml file:

<activity android:name=".Hello_World"
                  android:label="This is the Hello World Application">
   </activity>

And yes, to display customized title bar for your activity, go through this answer: How to change the text on the action bar

Answer 2

Try this...

final Activity activity = this;
activity.setTitle("Settings");

if you disabled the title bar using, this.requestWindowFeature(Window.FEATURE_NO_TITLE); remove it.

(OR)

Try this..

        final Activity activity = this;
        this.requestWindowFeature(Window.FEATURE_CUSTOM_TITLE);
        setContentView(R.layout.settings);
        activity.setTitle("Settings");

Answer 3

In your AndroidManifest.xml file you have a section for each activity that looks like this

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

where the android:label tag defines what the text in the titlebar is.
