How to create a back button in ActionBar AppCompatActivity Android Studio

I created a simple

Navigation Drawer Activity
and a
Basic Activity
which I named of
, so when I select a item from my Drawer i was able to navigate to my LoginActivity but there's no BackButton in my ActionBar, I came from Xamarin Forms and there, depending on navigation type, the back button was visible! So far I have :

public class MainActivity extends AppCompatActivity
implements NavigationView.OnNavigationItemSelectedListener {

protected void onCreate(Bundle savedInstanceState) {

Toolbar toolbar = (Toolbar) findViewById(;
setSupportActionBar(toolbar); ................

public boolean onNavigationItemSelected(MenuItem item) {
// Handle navigation view item clicks here.
int id = item.getItemId();

if (id == {
Intent intent = new Intent(this,LoginActivity.class);

Android Studio 2.2.2
compileSdkVersion 24


Change this code in your onCreate method:

Toolbar toolbar = (Toolbar) findViewById(;
toolbar.setNavigationIcon(R.drawable.YOUR_NAVIGATION_ICON); //This is the line to add

Furthermore, you can determine what clicking this icon does by:

    public boolean onOptionsItemSelected(MenuItem item) {
        switch (item.getItemId()) {

                //Whatever your require the navigation to do
                return true;
