Progress bar and webview issue

When I replace Relative Layout with Linear Layout my webview takes whole screen including toolbar but progress bar works fine AND when I use Linear Layout my web view starts below toolbar but it doesn't show progress bar.
My webview should start below toolbar with a progress bar in center.
Help me fix this

Use like this, If ImageButton is the single widget on the toolbar, you don't need to set margin, it will automatically be placed at left
<android.support.v7.widget.Toolbar

I have action bar along with app logo and app name.
So I want to reduce space between app logo and app name.
Below I have attached some screenshot.
A) Action bar I have
B) Action bar I want

Use Toolbar for this, it will provide greater customization.
Here is the sample example.
toolbar.xml
<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.Toolbar
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"

android:background="?attr/colorPrimary"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light"
app:layout_scrollFlags="scroll|enterAlways"
app:layout_collapseMode="pin">
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<!-- This is a centered logo -->
<ImageView
android:id="#+id/toolbar_logo"
android:src="#drawable/logo"

android:layout_height="fill_parent"
android:layout_marginRight="?attr/actionBarSize"
android:layout_marginTop="4dp"
android:layout_marginBottom="4dp"
android:layout_gravity="center" />
<!-- This is a centered title -->
<!--
<TextView

android:gravity="center_vertical"
android:visibility="gone"
android:text="#string/app_name"

-->
<!-- This is a custom left side button -->

Add any view inside toolbar as it is a viewgroup. Hopw this helps

Try adding these properties to toolBar
app:contentInsetLeft="0dp"
app:contentInsetStart="0dp"
app:contentInsetStartWithNavigation="0dp"
final toolbar should be something like this
<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/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="#drawable/paper9patch"
app:popupTheme="#style/AppTheme.PopupOverlay"
app:contentInsetLeft="0dp"
app:contentInsetStart="0dp"
app:contentInsetStartWithNavigation="0dp"
/>

Use this
getActionBar().setDisplayHomeAsUpEnabled(false)

Try this
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/AppTheme.AppBarOverlay">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?android:attr/actionBarSize"
android:supportsRtl="false"
app:popupTheme="#style/AppTheme.PopupOverlay">
<include layout="#layout/header_with_back"/>

Java code
Toolbar toolbar;
toolbar = (Toolbar) findViewById(R.id.toolbar);
toolbar.setPadding(0, 0, 0, 0);//for tab otherwise give space in tab
toolbar.setContentInsetsAbsolute(0, 0);
setSupportActionBar(toolbar);

Android setLogo isnt placed on the center of Action Bar

Hi I am using a toolbar and trying to set a logo to the center of action bar. But in the center there was title and (I think) thats why logo was starting from the left side of the action bar. Then I removed title to place the logo in center but it did no good. How can I solve this?
Here is the method I use to set the toolbar.
private void setToolBar(){
toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayShowTitleEnabled(false);
toolbar.setBackgroundColor(getResources().getColor(colorActionBar));
toolbar.setLogo(R.drawable.logoactionbar);
}
Here is the theme in my manifest
android:theme="#style/Theme.AppCompat.Light.NoActionBar">
And here is the decleration of toolbar
<<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_height="wrap_content" />
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:elevation="0dp"
android:background="#color/colorActionBar"
android:theme="#style/AppTheme.AppBarOverlay">

android:layout_gravity="center"
android:id="#+id/toolbar_title" />
</android.support.design.widget.AppBarLayout>
<include layout="#layout/content_home" />
</android.support.design.widget.CoordinatorLayout>

Try this:
<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">

android:src="#android:drawable/btn_star_big_off"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</LinearLayout>
</android.support.v7.widget.Toolbar>

Try this way
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/AppTheme.AppBarOverlay">
<android.support.v7.widget.Toolbar

android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary">
<ImageView

android:layout_height="wrap_content"
android:src="#drawable/your_logo"
android:layout_gravity="center"
android:id="#+id/toolbar_title" />
</android.support.v7.widget.Toolbar>
</android.support.design.widget.AppBarLayout>

Toolbar is just a ViewGroup, you can customize that as you want.
Try This:
<android.support.v7.widget.Toolbar
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="#color/color_primary"
android:minHeight="#dimen/abc_action_bar_default_height_material">
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:src="#drawable/ic_launcher"/>
</android.support.v7.widget.Toolbar>
