Toolbar In Settings Page Built With Preferencefragment

I built a Settings activity/screen for my app using this guide. Example code is bellow. What am I missing to be able to add a Toolbar to this new activity with a back arrow in it's

Solution 1:

You must include a toolbar in your activity layout. For example:

activity_main.xml

<?xml version="1.0" encoding="utf-8"?><RelativeLayoutxmlns:android="http://schemas.android.com/apk/res/android"xmlns:tools="http://schemas.android.com/tools"android:layout_width="match_parent"android:layout_height="match_parent"tools:context=".activities.SettingsActivity"><includeandroid:id="@+id/app_bar"layout="@layout/app_bar" /><FrameLayoutandroid:id="@+id/container"android:layout_width="match_parent"android:layout_height="match_parent"android:layout_below="@+id/app_bar"/></RelativeLayout>

app_bar.xml

<android.support.v7.widget.Toolbar
    android:id="@+id/toolbar"
    android:layout_width="match_parent"
    android:layout_height="?attr/actionBarSize"
    android:background="?attr/colorPrimary"
    app:popupTheme="@style/AppTheme.PopupOverlay" />

In your Activity.onCreate() get the toolbar and set a home button (the little arrow):

Toolbartoolbar= (Toolbar)findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);
        getSupportActionBar().setHomeButtonEnabled(true);
        getSupportActionBar().setDisplayHomeAsUpEnabled(true);

Set the SettingsActivity to be a child of parent MainActivity:

<activityandroid:name=".activities.SettingsActivity"android:label="@string/title_activity_main"android:parentActivityName=".activities.MainActivity" />

And that will give you that little arrow.

Also, do this:

publicclassSettingsActivityextendsAppCompatActivity

Not this:

publicclassSettingsActivityextendsActivity

In order to use support library.
