Add  actionBar setHomeButtonEnabled true     and then add the following   Override public boolean onOptionsItemSelected MenuItem menuItem               switch  menuItem getItemId              case android R id home              onBackPressed                return true          default              return super onOptionsItemSelected menuItem             As suggested by naXa I ve added a check on the itemId  to have it work correctly in case there are multiple buttons on the action bar

There are two ways to approach this   Option 1  Update the Android Manifest If the settings Activity is always called from the same activity  you can make the relationship in the Android Manifest  Android will automagically show the  back  button in the ActionBar   lt activity     android name   SettingsActivity      android label  Setting Activity  gt       lt meta-data         android name  android support PARENT ACTIVITY          android value  com example example MainActivity    gt   lt  activity gt    Option 2  Change a setting for the ActionBar If you don t know which Activity will call the Settings Activity  you can create it like this  First in your activity that extends ActionBarActivity  Make sure your  imports match the level of compatibility you are looking for     Override protected void onCreate Bundle savedInstanceState        super onCreate savedInstanceState       setContentView R layout activity settings test       ActionBar actionBar   getSupportActionBar        actionBar setHomeButtonEnabled true       actionBar setDisplayHomeAsUpEnabled true       Then  detect the  back button  press and tell Android to close the currently open Activity    Override public boolean onOptionsItemSelected MenuItem item        switch  item getItemId              case android R id home                 app icon in action bar clicked  goto parent activity              this finish                return true          default              return super onOptionsItemSelected item             That should do it

Firstly Use this    ActionBar bar   getSupportActionBar    bar setDisplayHomeAsUpEnabled true     Then set operation of button click in onOptionsItemSelected method    Override  public boolean onOptionsItemSelected MenuItem item        switch  item getItemId              case android R id home           finish            return true       default          return super onOptionsItemSelected item

You ll need to check menuItem getItemId   against android R id home in the onOptionsItemSelected method  Duplicate of Android Sherlock ActionBar Up button

this one worked for me    Override protected void onCreate Bundle savedInstanceState        super onCreate savedInstanceState       setContentView R layout activity your activity       getSupportActionBar   setDisplayHomeAsUpEnabled true              other stuff     Override public boolean onSupportNavigateUp        finish        return true      The method onSupportNavigateUp   is called when you use the back button in the SupportActionBar

Simpler and better  For API    16  Simply add  parentActivityName  for each activity in Manifest  The back button will automatically take u to the parent activity    lt activity         android name  com example myfirstapp DisplayMessageActivity          android label   string title activity display message          android parentActivityName  com example myfirstapp MainActivity   gt

After setting        actionBar setHomeButtonEnabled true     You have to configure the parent activity in your AndroidManifest xml   lt activity     android name  com example MainActivity      android label   string app name      android theme   style Theme AppCompat    gt   lt activity     android name  com example SecondActivity      android theme   style Theme AppCompat   gt       lt meta-data         android name  android support PARENT ACTIVITY          android value  com example MainActivity    gt   lt  activity gt    Look here for more information http   developer android com training implementing-navigation ancestral html
