Common background image for Actionbar (Toolbar) and statusbar
(1 answer)
Closed 4 years ago.
How can I add imageview on toolbar that it would be behind drawer and back arrow icons? that imageview should match toolbar height and wouldn't have any margins or padding on left side. I'm trying to achieve this for a while now and only solution I figured out to make custom Toolbar
Example:
Toolbar example
You can try this:
<RelativeLayout
android:id="#+id/my_toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:theme="#style/ActionBarThemeOverlay"
app:popupTheme="#style/ActionBarPopupThemeOverlay"
android:elevation="4dp"
android:background="#color/white">
<ImageView
android:layout_width="60dp"
android:layout_height="?attr/actionBarSize"
android:src="#drawable/yourImage"/>
</RelativeLayout>
create appbar_layout_xml in layouts add following code
<android.support.v7.widget.Toolbar
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="wrap_content"
android:background="#drawable/my_img"
app:titleTextColor="#color/colorWhite"
android:theme="#style/ThemeOverlay.AppCompat.Light"
>
</android.support.v7.widget.Toolbar>
and in your activity_xml include appbar_layout_xml layout
in styles keep theme as NoActionBar

I'm using navigation component and material toolbar.
I've just setup navigation component with material toolbar. By doing so whenever fragment changed the back button shown and the title of material toolbar changed by navigation component automatically.
The question is I just want to change the title gravity into center without removing those navigation components toolbar support.
How can I do that ?
Note : I`ve tried to change the toolbar style, but it seems does not work.
And creating an extra text view into toolbar view its not a solution since I want to use navigation component toolbar support.
Thanks in advance.
Starting from com.google.android.material:material:1.4.0 you can use app:titleCentered="true" to center the title.
<com.google.android.material.appbar.MaterialToolbar
android:id="#+id/materialToolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:title="Toolbar"
app:titleCentered="true"/>
I hope this helps. You can mark it as accepted if it matches your needs.
You can use a Custom Toolbar
<androidx.appcompat.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" />
<androidx.appcompat.widget.Toolbar/>
It's just a part of view Group, 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);
As a tricky way you can use: com.google.android.material.appbar.CollapsingToolbarLayout
<com.google.android.material.appbar.CollapsingToolbarLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
app:collapsedTitleGravity="center"
app:collapsedTitleTextAppearance="?attr/textAppearanceHeadline3"
app:expandedTitleGravity="center"
app:expandedTitleTextAppearance="?attr/textAppearanceHeadline1"
app:layout_scrollFlags="scroll|exitUntilCollapsed">
<androidx.appcompat.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:contentInsetStart="0dp"
app:contentInsetStartWithNavigation="0dp"
app:layout_collapseMode="pin"
app:navigationIcon="#drawable/ic_back_24dp"
app:title="#string/parvaneh_personal_info" />
</com.google.android.material.appbar.CollapsingToolbarLayout>

Android toolbar center title and custom font
(40 answers)
Closed 3 years ago.
I want to align my ToolBar Text to the center while keeping the triple dot menu at the end but I can't find a way to do it. Whenever I change gravity entire gravity changes.
My layout Image:
Layout Code:
<com.google.android.material.appbar.AppBarLayout
android:id="#+id/appBarLayout"
android:layout_width="match_parent"
android:layout_height="56dp"
android:layout_alignParentStart="true"
android:layout_gravity="center|top"
android:background="#fff"
app:elevation="0dp">
<androidx.appcompat.widget.Toolbar
android:id="#+id/main_toolbar"
android:layout_width="wrap_content"
android:layout_height="?attr/actionBarSize"
android:layout_gravity="end"
android:background="#fff"
app:title="CENTER">
</androidx.appcompat.widget.Toolbar>
</com.google.android.material.appbar.AppBarLayout>
Set width to match_parent for both of the them.
I'm trying to display my toolbar title in the center and to do it I use the method which is given in this answer :-Toolbar Center title
However, when I enable back button in my activity by following code:
toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
mActionBar = getSupportActionBar();
mActionBar.setDisplayHomeAsUpEnabled(true);
mActionBar.setDisplayShowHomeEnabled(true);
The title of toolbar doesn't show up in the center but slightly off-centered towards the right.
How can I achieve centered title without being affected by the back button or menu bar?
Add a TextView inside the Toolbar & don't forget to set the following attribute inside your TextView.
android:layout_marginRight="?android:attr/actionBarSize"
OR
android:layout_marginEnd="?android:attr/actionBarSize"
code snippet:
<android.support.v7.widget.Toolbar
android:id="#+id/custom_toolbar"
android:layout_width="match_parent"
android:layout_height="?android:attr/actionBarSize"
android:background="#android:color/holo_red_dark">
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="abc"
android:textColor="#android:color/white"
android:textSize="20sp"
android:layout_marginRight="?android:attr/actionBarSize"
android:gravity="center"/>
</android.support.v7.widget.Toolbar>
Refer to this tutorial for more information.
Having a placeholder image the same size as the back arrow and setting it to be invisible when the back arrow is not shown and gone when it's displayed did the trick for me.
<?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:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#color/blue"
android:minHeight="?attr/actionBarSize"
app:contentInsetEnd="0dp"
app:contentInsetLeft="0dp"
app:contentInsetRight="0dp"
app:contentInsetStart="0dp"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light"
app:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar">
<ImageView
android:id="#+id/iv_placeholder"
android:layout_width="72dp"
android:layout_height="48dp"
android:src="#drawable/ic_actionbar_hamburger"
android:visibility="invisible"/>
<TextView
android:id="#+id/logo_tv"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginEnd="?attr/actionBarSize"
android:gravity="center"
android:text=""
android:textColor="#color/white"
android:textStyle="normal"/>
</android.support.v7.widget.Toolbar>
Just add android:paddingEnd="72dp; to the Toolbar layout.
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?android:attr/actionBarSize"
app:contentScrim="#color/colorPrimary"
app:layout_collapseMode="pin"
android:paddingEnd="72dp"
app:popupTheme="#style/ThemeOverlay.AppCompat.Dark"
app:title="Title"/>
Just put your content in a child view inside the Toolbar tag in XML, using the following attributes:
android:layout_width="wrap_content"
android:layout_gravity="center"
Offical docs for Toolbar state:
One or more custom views. The application may add arbitrary child views to the Toolbar. They will appear at this position within the layout. If a child view's LayoutParams indicates a Gravity value of Gravity#CENTER_HORIZONTAL the view will attempt to center within the available space remaining in the Toolbar after all other elements have been measured.
This works for me, using androidx.appcompat.widget.Toolbar with a child view.
The reason why the title is not centered when you use a back button as navigation icon, is that navigation icon is represented as AppCompatImageButton and is added to the same layout as your title TextView. Using Arshak's answer is not a bad idea, but ?android:attr/actionBarSize is not a good way to define the end margin. As the action bar height is probably the same size as icon's width, it might work, but might not work on all devices. Could be a good idea to specify this size from material design guidelines.
In my case I was using an imageview inside the toolbar which I didnt want shifting around while navigating between fragments of a activity.
I kept it centered by placing it out the toolbar. I used constraintlayouts
<androidx.constraintlayout.widget.ConstraintLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent">
<com.google.android.material.appbar.MaterialToolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent">
</com.google.android.material.appbar.MaterialToolbar>
<ImageView
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:layout_constraintTop_toTopOf="#id/toolbar"
app:layout_constraintBottom_toBottomOf="#id/toolbar"
android:src="#drawable/ic_logo"
tools:ignore="ContentDescription" />
...
</androidx.constraintlayout.widget.ConstraintLayout>
I think the nicest and most up-to-date method is to have full control over the appbar. This way you can change other things from textview location.
<androidx.appcompat.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:title="#string/app_name"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/app_name"
android:textSize="20dp"
android:textColor="?attr/colorPrimary"
android:layout_centerInParent="true"
android:layout_marginEnd="20dp"/>
</RelativeLayout>
</androidx.appcompat.widget.Toolbar>
You can use this directly inside your activity. However, you may need to change the active toolbar by making such a definition in the activity where you added this toolbar.
Toolbar toolbar = findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
Dont set propterties like this
mActionBar = getSupportActionBar();
mActionBar.setDisplayHomeAsUpEnabled(true);
mActionBar.setDisplayShowHomeEnabled(true);
Do like this
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
// Title and subtitle
toolbar.setTitle(R.string.about_toolbar_title);
toolbar.setSubtitleTextColor(Color.WHITE);
toolbar.setTitleTextColor(Color.WHITE);
toolbar.setBackgroundColor(getResources().getColor(
R.color.themeToolbarColor));
toolbar.setNavigationIcon(R.drawable.ic_action_back);
toolbar.setNavigationOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
finish(); // to go back finish() will do your work.
//mActionBar.setDisplayHomeAsUpEnabled(true);
//mActionBar.setDisplayShowHomeEnabled(true);
}
});
I want an invisible toolbar but I want the back arrow and title to be displayed.
For achieving this, I did the following:
<?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"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:context="com.abc.xyz.AboutActivity">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/AppTheme.AppBarOverlay"
android:background="#color/toolbarTransparent">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"/>
</android.support.design.widget.AppBarLayout>
<FrameLayout
android:id="#+id/header_about"
android:layout_width="match_parent"
android:layout_height="160dp"
android:background="#color/colorAccent"/>
<ImageView
android:id="#+id/a"
android:layout_width="match_parent"
android:layout_height="70dp"
android:src="#drawable/a"
app:layout_anchor="#id/header_about"
app:layout_anchorGravity="bottom|center"/>
<include layout="#layout/content_about"/>
</android.support.design.widget.CoordinatorLayout>
But, I'm getting the following result (Look how toolbar is still appearing to be there):
I want the toolbar to get invisible and only the title and back arrow to be shown.
Please let me know how can I achieve that.
Sorry for bad format of the question. I'm still a beginner here.
AppBarLayout has default elevation value and that is why you can see shadow. You can set AppBarLayout elevation to 0dp
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/AppTheme.AppBarOverlay"
app:elevation="0dp"
android:background="#color/toolbarTransparent">
or just remove AppBarLayout. Toolbar is transparent by default.
If you want to use AppBarLayout with transparent background on Android Lolipop version and greater - set outline provider to BACKGROUND like below:
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
appBarLayout.setOutlineProvider(ViewOutlineProvider.BACKGROUND);
}
In this case when your background is transparent shadow will be not visible.
please check the android manifest file it should have AppTheme.NoActionBar then u will be able to hide it
I want to replace the title in my Toolbar by a logo like Twitter App.
I think we can replace this programmatically like that :
mToolbar = (Toolbar) findViewById(R.id.app_toolbar);
mToolbar.setLogo(R.drawable.ic_logo);
But I want to replace it directly in my XML toolBar declaration, but I can't see the property app:logo or android:logo.
<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/app_toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#color/colorPrimary"
android:minHeight="?attr/actionBarSize"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light"
app:theme="#style/MyCustomToolBarTheme" />
Please help me, thank you.
If you check source code of Toolbar and Toolbar's custom attributes, there are only a few attributes you can use to customize Toolbar, but logo is not one of them:
titleTextAppearance
subtitleTextAppearance
navigationIcon
...
Toolbar.setLogo(resId) seems to be the only option at the moment.
A toolbar contains a ViewGroup that you can populate with whatever views you wish --- you can add an ImageView there if you want a logo. Example:
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"
>
<ImageView
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:src="#drawable/ic_logo"/>
</android.support.v7.widget.Toolbar>
If you manually attach it to AppCompatActivity or ActionBar activity, it "becomes" an ActionBar, and then has to be manipulated using those code functions.
