Answer 1

Using AppCompat Theme, it can be done in this way. Define a custom style in styles.xml as follows:

<style name="CustomToolbarTheme" parent="Theme.AppCompat.NoActionBar">
        <item name="android:textColorPrimary">#FFFFFF</item>
        <item name="actionMenuTextColor">add_colour_your_choice</item>
        <item name="android:textColorSecondary">add_colour_your_choice</item>
        <item name="android:textSize">30sp</item>
    </style>

Then in the layout of the activity where you wish to change the action bar colour add a toolbar:

<android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"
        android:background="@android:color/white"
        android:elevation="0.5dp"
        android:theme="@style/CustomToolbarTheme"/>

And lastly in the java file of the activity, add the following lines to onCreate after setContentLayout :

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

Note: For this to work, you will have to add:

compile 'com.android.support:appcompat-v7:22.2.1'

to your build.gradle(module:app) under dependencies. (There are two dependencies, one under buildscipt and one at the end. ADD the line to the one AT THE END

I have created my own custom view and added it to action bar :

Please take a look on below code :

How to set custom view to ActionBar ?

public static ActionBar setCustomActionBar(Activity activity, ActionBar actionBar, String title) {
        if (actionBar != null) {
            ViewGroup actionBarLayout = (ViewGroup) activity.getLayoutInflater().inflate(R.layout.custom_actionbar, null);

            actionBar.setDisplayShowHomeEnabled(false);
            actionBar.setDisplayShowTitleEnabled(false);
            actionBar.setDisplayShowCustomEnabled(true);
            actionBar.setCustomView(actionBarLayout);
            actionBar.setBackgroundDrawable(new ColorDrawable(activity.getResources().getColor(R.color.actionbar_grey)));

            TextView actionBarTitle = (TextView) actionBarLayout.findViewById(R.id.text_actionbar_title);
            Typeface airplaneTypeface = Typeface.createFromAsset(activity.getAssets(), "fonts/Exo-Regular.otf");
            actionBarTitle.setText(title);
            actionBarTitle.setTypeface(airplaneTypeface);

//        SpannableString s = new SpannableString(title);
//        s.setSpan(new TypefaceSpan(activity, "fonts/airplane.ttf"), 0, s.length(),
//                Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
//        actionBar.setTitle(s);
        }
        return actionBar;
    }

custom_actionbar.xml file :

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@color/actionbar_grey"
    android:padding="@dimen/actionbar_padding">

    <ImageView
        android:id="@+id/img_up_indicator"
        android:layout_width="@dimen/actionbar_icon_width"
        android:layout_height="@dimen/actionbar_icon_height"
        android:layout_centerVertical="true"
        android:src="@drawable/ic_launcher" />

    <TextView
        android:id="@+id/text_actionbar_title"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerVertical="true"
        android:layout_toEndOf="@+id/img_up_indicator"
        android:layout_toRightOf="@+id/img_up_indicator"
        android:paddingLeft="@dimen/actionbar_title_left_padding"
        android:paddingStart="@dimen/actionbar_title_left_padding"
        android:text="@string/app_name"
        android:textColor="@color/logo_blue"
        android:textSize="@dimen/actionbar_title_text_size" />
</RelativeLayout>

How to use method :

setCustomActionBar(this, getActionBar(), getResources().getString(R.string.title_actionbar_home));

This is a sample that shows how to create custom view and set it to actionbar.

You can modify it as per your requirement.

Note : Here I used my resources that I did not provided you can modify as you wish.

Thanks.!!

try to add this

actionBar.setTitle(Html.fromHtml("<font color='#ff0000'>ActionBarTitle </font>"));

for font size

<style name="TextAppearance.Medium">
    <item name="android:textSize">18sp</item>
</style>

<style name="TextAppearance.Small">
    <item name="android:textSize">14sp</item>

</style>
