<android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:local="http://schemas.android.com/apk/res-auto"

    android:layout_height="wrap_content"
    android:background="@color/dark_blue"
    android:minHeight="?attr/actionBarSize"
    local:popupTheme="@style/ThemeOverlay.AppCompat.Light"
    local:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar" />

private Toolbar mToolbar;

//For Toolbar (Action bar) start
        mToolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(mToolbar);
        getSupportActionBar().setDisplayHomeAsUpEnabled(true);
        getSupportActionBar().setDisplayShowHomeEnabled(true);
        mToolbar.setNavigationIcon(R.drawable.ic_back_arrow);
        mToolbar.setNavigationOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                onBackPressed();
            }
        });
        getSupportActionBar().setTitle("Event Details");
        //For Toolbar (Action bar) end
