Complete example here http://www.freakyjolly.com/how-to-add-back-arrow-in-android-activity/

Use getSupportActionBar() Activity on which you want to show Back Icon

In OtherActivity.class

public class OtherActivity extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.other_activity);


    ActionBar actionBar = getSupportActionBar();
    if (actionBar != null) {
        actionBar.setDisplayHomeAsUpEnabled(true);
    }
}

public boolean onOptionsItemSelected(MenuItem item){
    switch (item.getItemId()) {
        case android.R.id.home:
            finish();
            return true;
    }
    return super.onOptionsItemSelected(item);
}

public boolean onCreateOptionsMenu(Menu menu) {
    return true;
}

}

This will add a event listen
