ActionBar actionBar = getSupportActionBar();
actionBar.setDisplayShowHomeEnabled(false);
actionBar.setDisplayShowCustomEnabled(true);
actionBar.setDisplayShowTitleEnabled(false);
View view = getLayoutInflater().inflate(R.layout.actionbar_title_back,
            null);
LayoutParams layoutParams = new LayoutParams(LayoutParams.MATCH_PARENT,
            LayoutParams.MATCH_PARENT);
actionBar.setCustomView(view, layoutParams);
Toolbar parent = (Toolbar) view.getParent();
parent.setContentInsetsAbsolute(0, 0);

2 Use Toolbar

toolbar = (Toolbar) findViewById(R.id.toolbar);
toolbar.setTitle("");
mTitle = (TextView) toolbar.findViewById(R.id.toolbar_title);
mTitle.setText(title);
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setDisplayShowHomeEnabled(true);

XML

<?xml version="1.0" encoding="utf-8"?>       
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"
        android:popupBackground="@color/red"
        app:popupTheme="@style/PopupTheme"
        app:theme="@style/ToolbarTheme" >

        <TextView
            android:id="@+id/toolbar_title"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="center"
            android:text="Toolbar Title"
            android:textColor="@color/white"
            android:textSize="17.0sp" />
    </android.support.v7.widget.Toolbar>
</LinearLayout>

Answer 3

In your XML code add these attributes:

<android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/re_app_toolbar"
    android:layout_width="match_parent"
    android:layout_height="?attr/actionBarSize"
    android:contentInsetEnd="0dp"
    android:contentInsetLeft="0dp"
    android:contentInsetRight="0dp"
    android:contentInsetStart="0dp"
    app:contentInsetEnd="0dp"
    app:contentInsetLeft="0dp"
    app:contentInsetRight="0dp"
    app:contentInsetStart="0dp">

it will fit all width of the view.
