Toolbar back button.

You can add your own 'up' button in toolbar, after all it is just a ViewGroup.

You can customize toolbar as much as you want, in your toolbar.xml, or wherever you have defined android.support.v7.widget.Toolbar in your layout add your 'up' button like given below :

   xmlns:android="http://schemas.android.com/apk/res/android"   android:id="@+id/toolbar"   android:minHeight="?attr/actionBarSize"   android:layout_height="?attr/actionBarSize"   android:background="@drawable/color_toolbar"   android:layout_width="match_parent">          android:id="@+id/upButton"       android:layout_width="wrap_content"       android:layout_height="wrap_content"       android:onClick="uphandler"       android:src="@drawable/backbutton"       android:layout_gravity="end"/>

Now, define uphandler function in your activity to listen to this up button :

public void uphandler(View v){       this.finish();    // This will kill current activity, and if previous activity is still opened in background, it will come in front.}
