Solution 1 - Android
After setting
actionBar.setHomeButtonEnabled(true);
Add the following code:
@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);
}
}
Solution 2 - Android
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.

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.

After setting
actionBar.setHomeButtonEnabled(true);
You have to configure the parent activity in your AndroidManifest.xml
<activity
android:name="com.example.MainActivity"
android:label="@string/app_name"
android:theme="@style/Theme.AppCompat" />
<activity
android:name="com.example.SecondActivity"
android:theme="@style/Theme.AppCompat" >
<meta-data
android:name="android.support.PARENT_ACTIVITY"
android:value="com.example.MainActivity" />
</activity>

Solution 5 - Android
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
<activity
android:name=".SettingsActivity"
android:label="Setting Activity">
<meta-data
android:name="android.support.PARENT_ACTIVITY"
android:value="com.example.example.MainActivity" />
</activity>
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!
Solution 6 - Android
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);
}
}
Solution 7 - Android
You'll need to check menuItem.getItemId()
against android.R.id.home
in the onOptionsItemSelected
method

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.
<activity
android:name="com.example.myfirstapp.DisplayMessageActivity"
android:label="@string/title_activity_display_message"
android:parentActivityName="com.example.myfirstapp.MainActivity" >

Use this to show back button and move to previous activity,
final ActionBar actionBar = getSupportActionBar();
assert actionBar != null;
actionBar.setDisplayHomeAsUpEnabled(true);
actionBar.setHomeAsUpIndicator(R.drawable.back_dark);
@Override
public boolean onOptionsItemSelected(final MenuItem item) {
switch (item.getItemId()) {
case android.R.id.home:
onBackPressed();
return true;
default:
return super.onOptionsItemSelected(item);
}
}
Solution 10 - Android
if anyone else need the solution
@Override
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
if (id == android.R.id.home) {
onBackPressed();
}
return super.onOptionsItemSelected(item);
}
Solution 11 - Android
Add this line in onCreate() method
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
then Override this method
@Override
public boolean onSupportNavigateUp(){
finish();
return true;
}
