Setting Action Bar title and subtitle

I want to set title and subtitile of my action bar before compile time. I got a way to do it like this:

ActionBar ab = getActionBar();
ab.setTitle("My Title");
ab.setSubtitle("sub-title");

But I don't want to do it on run time. Is there any xml file or any location where I can specify these titles?

I am trying to achieve this:

Edit:

The reason why I want it in xml is that I want my app to be supported in API level 8. And the method getActionBar() is supported at least on level 11.

You can do something like this to code for both versions:

/**
 * Sets the Action Bar for new Android versions.
 */
@TargetApi(Build.VERSION_CODES.HONEYCOMB)
private void actionBarSetup() {
  if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
    ActionBar ab = getActionBar();
    ab.setTitle("My Title");
    ab.setSubtitle("sub-title"); 
  }
}

  

Then call actionBarSetup() in onCreate(). The if runs the code only on new Android versions and the @TargetApi allows the code to compile. Therefore it makes it safe for both old and new API versions.

Alternatively, you can also use ActionBarSherlock (see edit) so you can have the ActionBar on all versions. You will have to do some changes such as making your Activities extend SherlockActivity and calling getSupportActionBar(), however, it is a very good global solution.

Edit

Note that when this answer was originally written, ActionBarSherlock, which has since been deprecated, was the go-to compatibility solution.

Nowadays, Google's appcompat-v7 library provides the same functionality but is supported (and actively updated) by Google. Activities wanting to implement an ActionBar must:

• extend AppCompatActivity
• use a Theme.AppCompat derivative

To get an ActionBar instance using this library, the aptly-named getSupportActionBar() method is used.

The title for the actionbar could be in the AndroidManifest, here:

<activity 
    . . .
          android:label="string resource" 
    . . .
</activity>

> android:label > A user-readable label for the activity. The label is > displayed on-screen when the activity must be represented to the user. > It's often displayed along with the activity icon. If this attribute > is not set, the label set for the application as a whole is used > instead (see the element's label attribute). The > activity's label — whether set here or by the element — > is also the default label for all the activity's intent filters (see > the element's label attribute). The label should be > set as a reference to a string resource, so that it can be localized > like other strings in the user interface. However, as a convenience > while you're developing the application, it can also be set as a raw > string.

Try this one:

android.support.v7.app.ActionBar ab = getSupportActionBar();
ab.setTitle("This is Title");
ab.setSubtitle("This is Subtitle");

There is another option that no one commented, from the Support Library V7 was implemented by Google ActionBarSupport, which is compatible ActionBar from Android 2.2 to the last.
If you change your ActionBar this you can do getSupportActionBar().setTitle("") on all Android versions.

Nope! You have to do it at runtime.

If you want to make your app backwards compatible, then simply check the device API level. If it is higher than 11, then you can fiddle with the ActionBar and set the subtitle.

if(Integer.valueOf(android.os.Build.VERSION.SDK) >= 11){
    //set actionbar title
}

    <activity android:name=".yourActivity" android:label="@string/yourText" />

Put this code into your android manifest file and it should set the title of the action bar to what ever you want!

Try This

Just go to your Manifest file. and You have define the label for each activity in your manifest file.

<activity
        android:name=".Search_Video"
        android:label="@string/app_name"
        android:screenOrientation="portrait">
    </activity>

here change

android:label="@string/your_title"

supportActionBar?.title = "Hola tio"
supportActionBar?.subtitle = "Vamos colega!"

Try This:

In strings.xml add your title and subtitle...

ActionBar ab = getActionBar();
ab.setTitle(getResources().getString(R.string.myTitle));
ab.setSubtitle(getResources().getString(R.string.mySubTitle));

This is trivial one-liner in Kotlin

supportActionBar?.title = getString(R.string.coolTitle)

For an activity you can use this approach to specify a subtitle, along with the title, in the manifest.

Manifest:

<activity
    android:name=".MyActivity"
    android:label="@string/my_title"
    android:description="@string/my_subtitle">
</activity>

Activity:

try {
    ActivityInfo activityInfo = getPackageManager().getActivityInfo(getComponentName(), PackageManager.GET_META_DATA);
    //String title = activityInfo.loadLabel(getPackageManager()).toString();
    int descriptionResId = activityInfo.descriptionRes;
    if (descriptionResId != 0) {
        toolbar.setSubtitle(Utilities.fromHtml(getString(descriptionResId)));
    }
}
catch(Exception e) {
    Log.e(LOG_TAG, "Could not get description/subtitle from manifest", e);
}

This way you only need to specify the title string once, and you get to specify the subtitle right alongside it.

You can set the title in action-bar using AndroidManifest.xml. Add label to the activity

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