Toolbar title with custom view

问题

I am attempting to show both a title, using setTitle and a custom view in my toolbar.

I am not treating it as an actionbar, instead as nothing more than a view.

I am adding both the titles and custom view in Java

 toolbar = (Toolbar) view.findViewById(R.id.toolbar);

    if (title != null) {
        toolbar.setTitle(title);
        toolbar.setTitleTextColor(getResources().getColor(android.R.color.white));
    }

    if (subtitle != null) {
        toolbar.setSubtitle(subtitle);
        toolbar.setSubtitleTextColor(getResources().getColor(android.R.color.white));
    }

    // Add switch view to toolbar
    View switchView = LayoutInflater.from(getActivity())
            .inflate(R.layout.device_list_switch, null);
    toolbar.addView(switchView);

The xml for my switch view is

<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="@android:color/holo_blue_bright">


<TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignBottom="@+id/discoverable"
    android:layout_alignParentBottom="true"
    android:layout_alignTop="@+id/discoverable"
    android:layout_toLeftOf="@+id/discoverable"
    android:layout_toStartOf="@+id/discoverable"
    android:gravity="center"
    android:text="@string/discoverable_switch_label"
    android:textColor="@android:color/white"
    />

<Switch
    android:id="@+id/discoverable"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true"
    android:layout_alignParentEnd="true"
    android:layout_alignParentRight="true"
    android:layout_marginLeft="@dimen/discoverable_switch_margin_left"
    android:layout_marginStart="@dimen/discoverable_switch_margin_left"/>

</RelativeLayout>

What happens is that the RelativeLayout fills the entire toolbar area and the title isn't visible.

Any ideas?

This can be solved by adding your own title (and subtitle, if you need it) text views inside the toolbar alongside your custom view.

But perhaps a better way is to use a second toolbar nested inside the first. That way, all formatting is taken care of for you.

<android.support.v7.widget.Toolbar xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/topToolbar"
    android:layout_alignParentTop="true"
    android:layout_height="wrap_content"
    android:layout_width="match_parent">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="horizontal">

        <android.support.v7.widget.Toolbar xmlns:app="http://schemas.android.com/apk/res-auto"
            android:id="@+id/titleToolbar"
            android:layout_width="wrap_content"
            android:layout_height="match_parent"
            app:contentInsetStart="0dp"
            app:contentInsetLeft="0dp">
        </android.support.v7.widget.Toolbar>

        <CustomView... />

    </LinearLayout>

</android.support.v7.widget.Toolbar>

If you are not using the Toolbar as an ActionBar, then maybe you could just use a layout.

I used a LinearLayout instead of a Toolbar.

What advantages is Toolbar giving you?
