Title image alignment in toolbar android

Why image in toolbar not align in center when remove the menu items in android.
If i have hide the menu items the title moved right.that is some spaces added between navigation icon and title.
My code
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:contentInsetLeft="0dp"
app:contentInsetStart="0dp"
app:contentInsetRight="0dp"
app:contentInsetStartWithNavigation="0dp"
android:background="#FFF">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
>
<ImageView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="5dp"
android:id="#+id/pg_title"
android:layout_centerHorizontal="true"
android:src="#drawable/logo"
/>
</LinearLayout>
</android.support.v7.widget.Toolbar>

try this add this toolbar in your layout xml file
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:popupTheme="#style/AppTheme.PopupOverlay">
<include layout="#layout/actionbar_layout" />
</android.support.v7.widget.Toolbar>
create a new actionbar_layout for your toolbar like this
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center"
android:orientation="horizontal">
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/ic_bike" />
</LinearLayout>
now in your activity file just add below code
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
getSupportActionBar().setTitle("");

</FrameLayout>

okey i see your video and i have same problem in past
The answer is this :
When you click on icon in bottom bar to new fragment load do this :
For Disable :
Toolbar toolbar = findViewById(R.id.toolbar); // or however you need to do it for your code
AppBarLayout.LayoutParams params = (AppBarLayout.LayoutParams) toolbar.getLayoutParams();
params.setScrollFlags(0); // clear all scroll flags
And when click on home botton in bottom bar do it to enable Scroll toolbar:
For Enable :
params.setScrollFlags(AppBarLayout.LayoutParams.SCROLL_FLAG_SCROLL
| AppBarLayout.LayoutParams.SCROLL_FLAG_ENTER_ALWAYS);

AppBarLayout elevation hides toolbar

I'm trying to disable the shadow below a transparent AppBarLayout/Toolbar. Here's the layout:
<android.support.design.widget.CoordinatorLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:background="#000">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:fitsSystemWindows="true"
android:background="#android:color/transparent"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar">
<android.support.v7.widget.Toolbar
android:id="#+id/imagePreviewToolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize" />
</android.support.design.widget.AppBarLayout>
<include layout="#layout/content_image_preview" />
</android.support.design.widget.CoordinatorLayout>
I already tried with
app:elevation="0dp"
and
getSupportActionBar().setElevation(0);
but that makes the UP arrow invisible. I also tried to remove the AppBarLayout and use only the Toolbar, but the problem persists.
Anyone has a solution?
EDIT:
Replacing the AppBarLayout + Toolbar combo with this code:
<android.support.v7.widget.Toolbar
android:id="#+id/imagePreviewToolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="#android:color/transparent"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light"
app:elevation="0dp"/>
partially fixed the problem. Now the Toolbar becomes invisible only when the device is in landscape mode! The Android Studio Layout Editor shows me the Toolbar in both orientations just fine, so I don't really know what the problem could be..

after some tries i did find that ToolBar should be the last view in this case else if it will be first then the view coming after it will overlap it as it has height set to match_parent so try this way in layout.
Layout
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout
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" >
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="#+id/imagePreviewToolbar" >
<ImageView
android:id="#+id/image_preview"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#drawable/galacticos"
android:contentDescription="abc"
android:scaleType="fitCenter" />
<LinearLayout
android:id="#+id/actionBtns"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:orientation="horizontal"
android:padding="16dp" >
<ImageButton
android:id="#+id/setBackgroundBtn"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:background="#null"
android:contentDescription="abc"
android:src="#drawable/ic_launcher" />
<ImageButton
android:id="#+id/downloadBtn"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:background="?selectableItemBackgroundBorderless"
android:clickable="true"
android:contentDescription="abc"
android:src="#drawable/ic_launcher" />
</LinearLayout>
</RelativeLayout>
<android.support.v7.widget.Toolbar
android:id="#+id/imagePreviewToolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:fitsSystemWindows="true"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light"
app:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar" />
And don't forget to initialize this all and set your title to false to only show the toolBar back button:
Activity Code
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.test);
Toolbar mToolBar = (Toolbar) findViewById(R.id.imagePreviewToolbar);
setSupportActionBar(mToolBar);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setDisplayShowTitleEnabled(false);
getSupportActionBar().setHomeButtonEnabled(true);
}

Hope i helped you.

Make toolbar like this:
<android.support.design.widget.AppBarLayout
android:id="#+id/myAppBar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:elevation="0dp"...>
</android.support.design.widget.AppBarLayout>
And after that in your Activity;
findViewById(R.id.myAppBar).bringToFront();

How to get title at center of Toolbar

I am trying to get the title of the Collapsed Toolbar to the center. But there seems to be some bug in the basic layout itself. The title has an offset for some reason.
Unable to figure out how to fix this. Also there seems to be no property to apply negative margin/padding to the collapsedTitle.
<android.support.design.widget.CoordinatorLayout
android:id="#+id/coordinator_layout"
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:fitsSystemWindows="true"
android:orientation="vertical">
<android.support.design.widget.AppBarLayout
android:id="#+id/app_bar"
android:layout_width="match_parent"
android:layout_height="#dimen/app_bar_height"
android:fitsSystemWindows="true"
android:theme="#style/XXXXAppTheme.AppBarOverlay">
<android.support.design.widget.CollapsingToolbarLayout
android:id="#+id/collapsingToolbar"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
app:collapsedTitleGravity="center"
app:contentScrim="?attr/colorPrimary"
app:expandedTitleGravity="top|center_horizontal"
app:expandedTitleMarginTop="-10dp"
app:layout_scrollFlags="scroll|exitUntilCollapsed"
app:title="REGISTER">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:layout_collapseMode="pin"
app:popupTheme="#style/XXXXAppTheme.PopupOverlay"/>
<ImageView
android:id="#+id/ivContent"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:src="#drawable/white_background"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
app:layout_collapseMode="parallax"/>
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:clipToPadding="false"
android:orientation="vertical"
app:layout_behavior="#string/appbar_scrolling_view_behavior">
<FrameLayout
android:id="#+id/flContainer"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
</LinearLayout>

Try this within your "Toolbar"
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar_top"
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:minHeight="?attr/actionBarSize"
android:background="#color/color"
app:theme="#style/ToolBarTheme" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Register"
android:layout_gravity="center"
android:id="#+id/toolbar_title" />
</android.support.v7.widget.Toolbar>

To make it centered, please follow the steps:
To use a custom title in your Toolbar all you need to do is remember
is that Toolbar is just a fancy ViewGroup so you can add a custom
title like so:
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar_top"
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:minHeight="?attr/actionBarSize"
android:background="#color/action_bar_bkgnd"
app:theme="#style/ToolBarTheme" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Toolbar Title"
android:layout_gravity="center"
android:id="#+id/toolbar_title" />
</android.support.v7.widget.Toolbar>
This means that you can style the TextView however you would like
because it's just a regular TextView. So in your activity you can
access the title like so:
Toolbar toolbarTop = (Toolbar) findViewById(R.id.toolbar_top);
TextView mTitle = (TextView) toolbarTop.findViewById(R.id.toolbar_title);
From: Android toolbar center title and custom font
To remove the default app name title, do this:
setSupportActionBar(toolbar_top);
getSupportActionBar().setDisplayShowTitleEnabled(false);
Hope it help

You should use this. To add TextView in side Toolbar
<android.support.v7.widget.Toolbar
android:layout_width="match_parent"
android:layout_height="130dp"
android:id="#+id/toolbar">
<android.support.v7.widget.AppCompatTextView
android:id="#+id/toolbar_title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/app_name"
android:layout_gravity="center"/>
</android.support.v7.widget.Toolbar>

How to set ActionBar for transaparent and keep it over ImageView

I want to make the ActionBar transparent and it above the image like this picture.
How set it?

Layout
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#drawable/background_white"
android:minHeight="?attr/actionBarSize" />
<FrameLayout
android:id="#+id/framelayout_content"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</FrameLayout>
Solution 1#
//whole toolbar will be transparent
mToolbar.setAlpha(0.0f);
Solution 2#
//only background of toolbar will be transparent
mToolbar.getBackground().setAlpha(0);

#maros136:
I think you should add the toolbar layout below the framelayout_content and the root layout should be a RelativeLayout in order to have the toolbar always on top.
Like this:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/main_details_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
Your layout here
</LinearLayout>
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="#color/transparent"
/>
</RelativeLayout>
