In pre-5.0 documentation there is an example that shows tabs inside the Action bar:
https://developer.android.com/guide/topics/ui/actionbar.html#Tabs
What is the correct way to achieve that in 5.0+ interface with new Toolbar?
Do I just place widget.TabLayout inside widget.Toolbar?
You can place the tablayout widget inside the toolbarwidget like
<android.support.v7.widget.Toolbar
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:id="#+id/toolbar"
android:background="?attr/colorPrimary">
<android.support.design.widget.TabLayout
android:id="#+id/tabLayout"
android:layout_height="wrap_content"
android:layout_width="match_parent"/>
</android.support.v7.widget.Toolbar>

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>
After creating a Navigation Drawer activity in my Android Studio project I want to add a search view into the toolbar instead of my app name. How do I do it? Can the toolbar be customized based on my needs or creation of custom toolbar is required?
If you have selected Navigation Drawer activity while creating new project Android studio would have by default created the file app_bar_main.xml file
You should be able to find the below code given by default
<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" />
Replace the above code with below code to get search view within toolbar
<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">
<SearchView
android:layout_width="match_parent"
android:layout_height="wrap_content" /></android.support.v7.widget.Toolbar>
Here is the code.
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout

android:layout_margin="16dp"
android:src="#android:drawable/ic_media_play"

app:layout_anchor="#id/main_viewpager"
app:layout_anchorGravity="bottom|end"/>
</android.support.design.widget.CoordinatorLayout>
The problem:
1) Toolbar is not visible.
2) Collapsing toolbar doesn't collapse at all. [Solved]
3) Viewpager and FAB also not visible if put inside nestedScrollView. [Solved]
Extra detail:
Layout for fragments of Viewpager have Linearlayout as root and inside that have a recyclerview.
Everything seems to be alright as per the code. Unable to understand what is missing. A good explanation of how coordinator layout and collapsing toolbar work together would also indeed help.
1) Toolbar is not visible.
First of all you need define what Toolbar do you want to use in your activity class:
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
Change existing xml code:
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="?attr/colorPrimary"
app:title="#string/app_name"
app:layout_collapseMode="parallax">
</android.support.v7.widget.Toolbar>
to:
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize" //set initial height
app:popupTheme="#style/ThemeOverlay.AppCompat.Light" //this might be also useful
app:title="#string/app_name"
app:layout_collapseMode="parallax" />
2) Collapsing toolbar doesn't collapse at all.
Did your activity using correct theme. Set to your AppBarLayout:
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"
as in this example: include_list_viewpager.xml
3) Viewpager and FAB also not visible if put inside nestedScrollView.
There's no reason to do that. Adding these lines:
android:layout_marginTop="?attr/actionBarSize"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
to ViewPager should be enough.
Both of them should be direct children of CoordinatorLayout.
Follow this example: http://blog.nkdroidsolutions.com/collapsing-toolbar-with-tabs-android-example/
If you're new to Material Design or feel a bit lost with some its behaviours, I highly recommend to check Chris Banes Material Design project cheesequare: https://github.com/chrisbanes/cheesesquare/
Hope it will help
First of all you should tell your activity that what toolbar you are using, so in onCreate method you should have:
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
your second and third problem should solve together. You should use NestedScrollView as the main layout for fragments inside ViewPager and then inside that, put your LinearLayout or anything else.
Right now, as an example, the app looks like this:
How do I programatically or using xml make the appbar look like this:
I've tried setting the appbar icon as if it were a background, but it looks rather odd.
You can add the application icon as a menu item to appbar with android:show="always".
Another workaround is to place an imageView in your toolbar, which is inside the appBar. You can then change the position of this imageview through xml code or programmatically.
<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="?actionBarSize"
android:background="?attr/colorPrimary"
android:theme="#style/ToolbarColoredBackArrow"
app:popupTheme="#style/AppTheme.PopupOverlay" >
<ImageView
android:id="#+id/indicator"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="#dimen/margin_small"/>
</android.support.v7.widget.Toolbar>
</android.support.design.widget.AppBarLayout>
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.
