How do I change the android actionbar title and ic

Question

I'm trying to do some things on the ActionBar in Android.

I've already added new items in the right side of the action bar.

How can I change the left side of the action bar? I want to change the icon and the text, and I want to add a "Back Button" in the action bar for the other screens

Answer 1

Go to manifest in which specific activity you want to change Action bar Title name and write android:label="Title name"

Answer 2

If you want to change the Action bar title just give the following 1 line code in the onCreate() of your Activity

getActionBar().setTitle("Test");

Answer 3

For that, you can do it in 2 ways: XML or Java. See here: How to change the text on the action bar

So:

XML:

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

Java:

public class TitleBar extends Activity {
/** Called when the activity is first created. */
@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);
       }
 }
}

Answer 4

For set Title :

getActionBar().setTitle("Title");

For set Icon :

getActionBar().setIcon(R.drawable.YOUR_ICON_NAME);

Answer 5

You just need to add these 3 lines of code. Replace the icon with your own icon. If you want to generate icons use this

getSupportActionBar().setHomeAsUpIndicator(R.drawable.icon_back_arrow);
getActionBar().setHomeButtonEnabled(true);
getActionBar().setDisplayHomeAsUpEnabled(true);

Answer 6

I used the following call inside onNavigationItemSelected:

HomeActivity.this.setTitle(item.getTitle());
