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'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>
So began researching how to create an action bar with an autocomplete text view for search. Most of the solutions I've found come close to what I'm looking for however they all seem to be focused on cramming any and additional views added to the action bar on one line.
Further complicating this, is the fact that this is all located in a view pager fragment whose parent activity already has an action bar. Thus using the setSupportingActionBar call with a Toolbar throws an illegal state exception.
Not sure if what I am accomplishing is actually supported but here it goes.
The end result I am looking for is this
Here is what I wrote
*custom view containing the autocomplete text view named autocomplete.xml *
<?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="wrap_content"
android:orientation="vertical">
<AutoCompleteTextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/search_text_view"
android:paddingTop="15dp"
android:paddingBottom="15dp"
android:paddingLeft="20dp"
android:paddingRight="20dp"
android:drawableLeft="#drawable/ic_search_blue"
android:background="#drawable/white_edittext"/>
</LinearLayout>
here is the code in my fragment used to setup the action bar
private void initializeActionsBarWithAutocomplete(){
ActionBar actionBar = ((MyParentActivity) getActivity()).getSupportActionBar();
actionBar.setTitle(getResources().getString(R.string.default_title));
View autoCompleteView = LayoutInflater.from(getContext()).inflate(R.layout.autocomplete, null);
mSearchTextView = (AutoCompleteTextView) autoCompleteView.findViewById(R.id.search_text_view);
mSearchTextView.setAdapter(mTypeAheadAdapter);
mSearchTextView.setOnItemClickListener(this);
mSearchTextView.addTextChangedListener(this);
actionBar.setCustomView(autoCompleteView);
actionBar.setDisplayShowCustomEnabled(true);
actionBar.setDisplayShowTitleEnabled(true);
actionBar.setDisplayHomeAsUpEnabled(true);
}
What I end up getting is this
So assuming what I'm trying to do is possible, and I'm at least on the right track, what exactly is going wrong here. I assumed that having the custom view match parent would force the textview to take up its own line and expand the size of the action bar accordingly. That is clearly not the case. I looked at some articles that allowed you to set the height of the action bar explicitly but from what I can comprehend, that method will result in the same appearance with a bunch of white space under views in the action bar.
You can use Toolbar widget in XML and customize it as per your needs.
Here is an layout of Toolbar containing AutoCompleteTextView:
<android.support.design.widget.AppBarLayout
android:id="#+id/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="wrap_content"
android:background="?attr/colorPrimary"
app:layout_scrollFlags="scroll|enterAlways"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light"
app:titleTextColor="#FFFFFF">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:paddingTop="20dp">
<TextView
android:id="#+id/toolbar_title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="8dp"
android:text="#string/app_name"
android:textColor="#ffffff"
android:textSize="20sp"
android:textStyle="bold" />
<android.support.v7.widget.CardView
android:layout_width="match_parent"
android:layout_height="40dp"
android:layout_margin="8dp"
android:layout_centerInParent="true"
cardview:cardBackgroundColor="#ffffff"
cardview:cardCornerRadius="2dp"
cardview:cardElevation="0dp">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:focusable="true"
android:focusableInTouchMode="true">
<AutoCompleteTextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/search_text_view"
android:paddingTop="15dp"
android:paddingBottom="15dp"
android:paddingLeft="20dp"
android:paddingRight="20dp"
android:drawableLeft="#drawable/ic_search_blue"
android:background="#drawable/white_edittext"/>
</RelativeLayout>
</android.support.v7.widget.CardView>
</LinearLayout>
</android.support.v7.widget.Toolbar>
</android.support.design.widget.AppBarLayout>
In your JAVA code try this:
Toolbar mToolBar;
ActionBar mActionBar;
AutoCompleteTextView mSearchTextView;
private void initializeActionsBarWithAutocomplete(){
// ToolBar
mToolBar = (Toolbar) findViewById(R.id.toolbar);
// AutoCompleteTextView
mSearchTextView = (AutoCompleteTextView) mToolBar.findViewById(R.id.search_text_view);
mSearchTextView.setAdapter(mTypeAheadAdapter);
mSearchTextView.setOnItemClickListener(this);
mSearchTextView.addTextChangedListener(this);
setSupportActionBar(mToolBar);
// ActionBar
mActionBar = getSupportActionBar();
mActionBar.setTitle(getResources().getString(R.string.default_title));
mActionBar.setDisplayHomeAsUpEnabled(true);
}
OUTPUT:
Hope this will help~
My intentions are to use a custom view ( TextView + ImageView ) and put it as a view into a Toolbar.How can i get the style of the toolbar's default TextView for title?I'd like my TextView in my custom view to have the exactly the same outfit.I tried styling it like:
setTypeface(Typeface.DEFAULT_BOLD);
setTextSize(18);
setTextColor(Color.BLACK);
But it still looks different,are those described somewhere because i really couldn't find them.Or can i re-use the style of the title somehow?I'm getting a bit confused when it comes to styling especially from code.
Thanks in advance.
Inside your coordinate layout, place 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="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:popupTheme="#style/AppTheme.PopupOverlay" >
<TextView
android:id="#+id/title"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textSize="20dp"
android:text="Ezy Ride"
android:textColor="#ffffff" />
</android.support.v7.widget.Toolbar>
</android.support.design.widget.AppBarLayout>
Now your app bar layout is ready. Customise it as you require.
In your java
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
TextView toolbarTitle = (TextView)toolbar.findViewById(R.id.title);
//here set all you want!!
I have an appCompatActivity with a supportActionBar similar to whatsApp chat screen interface. Having been able to customise the actionbar with all the necessary components, I am not not able to apply padding/margin of any sort on the leftmost up/back button. However, with rest of the items I set up in the toolbar are aligned properly.
Here is how my layout of the activity looks like:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/relMainLayout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.design.widget.AppBarLayout
android:id="#+id/appbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar">
<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/ThemeOverlay.AppCompat.Light"
app:layout_scrollFlags="scroll|enterAlways">
<de.hdodenhof.circleimageview.CircleImageView
android:id="#+id/avatar"
android:layout_width="#dimen/action_bar_avatar_size"
android:layout_height="#dimen/action_bar_avatar_size"/>
<TextView
android:id="#+id/txtUserName"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textSize="20dp"
android:textAppearance="#style/TextAppearance.AppCompat.Body1"/>
</android.support.v7.widget.Toolbar>
</android.support.design.widget.AppBarLayout>
...
In the activity:
mImageViewAvatar = (ImageView) findViewById(R.id.avatar);
mTextViewUserName = (TextView) findViewById(R.id.txtUserName);
final Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setDisplayShowTitleEnabled(false);
mImageViewAvatar.setBackgroundImage(Contacts.getImage());
mTextViewUserName.setText(recipientId);
I have tried to set my layout_marginLeft to a negative value as well to the image even, it does not move to left. How do I apply margin/padding alignments to only this toolbar? Not the toolbar used in the application.
I guess you're looking for app:contentInsetLeft respectively app:contentInsetStart. Setting these attributes to 0dp will remove the padding - see the following two screenshots:
Without explicity setting contentInset:
Setting contentInset to 0dp
Please note: This won't work if you're using getSupportActionBar().setDisplayHomeAsUpEnabled(true) since the drawable which will be used by the system has a padding which can't be removed. See the following Screenshot:
So if you're trying to achieve the same as WhatsApp you have to use your own "back-button" drawable and add it to your Toolbar layout.
Edit
That's how I would do it:
*.xml
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
android:elevation="4dp"
app:contentInsetLeft="0dp"
app:contentInsetStart="0dp"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light">
<LinearLayout
android:id="#+id/layout_back_button"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:background="?attr/selectableItemBackgroundBorderless"
android:gravity="center_vertical">
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/ic_action_arrow_back" />
<ImageView
android:layout_width="40dp"
android:layout_height="40dp"
android:src="#drawable/avatar" />
</LinearLayout>
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="8dp"
android:text="StackOverflow"
android:textAppearance="#style/TextAppearance.AppCompat.Body1"
android:textSize="20dp" />
</android.support.v7.widget.Toolbar>
Java code
Toolbar tb = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(tb);
getSupportActionBar().setTitle(null);
View view = findViewById(R.id.layout_back_button);
view.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
onBackPressed();
}
});
Result:
Notice that I wrapped the back button drawable and the avatar in an extra layout, which has the selectableItemBackgroundBorderless set as the background. Due that we achieve this ripple effect like in WhatsApp.
I am attempting to show both a title, using setTitle and a custom view in my toolbar.
I am not treating it as an actionbar, instead as nothing more than a view.
I am adding both the titles and custom view in Java
toolbar = (Toolbar) view.findViewById(R.id.toolbar);
if (title != null) {
toolbar.setTitle(title);
toolbar.setTitleTextColor(getResources().getColor(android.R.color.white));
}
if (subtitle != null) {
toolbar.setSubtitle(subtitle);
toolbar.setSubtitleTextColor(getResources().getColor(android.R.color.white));
}
// Add switch view to toolbar
View switchView = LayoutInflater.from(getActivity())
.inflate(R.layout.device_list_switch, null);
toolbar.addView(switchView);
The xml for my switch view is
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#android:color/holo_blue_bright">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignBottom="#+id/discoverable"
android:layout_alignParentBottom="true"
android:layout_alignTop="#+id/discoverable"
android:layout_toLeftOf="#+id/discoverable"
android:layout_toStartOf="#+id/discoverable"
android:gravity="center"
android:text="#string/discoverable_switch_label"
android:textColor="#android:color/white"
/>
<Switch
android:id="#+id/discoverable"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_alignParentEnd="true"
android:layout_alignParentRight="true"
android:layout_marginLeft="#dimen/discoverable_switch_margin_left"
android:layout_marginStart="#dimen/discoverable_switch_margin_left"/>
</RelativeLayout>
What happens is that the RelativeLayout fills the entire toolbar area and the title isn't visible.
Any ideas?
If you are not using the Toolbar as an ActionBar, then maybe you could just use a layout.
I used a LinearLayout instead of a Toolbar.
What advantages is Toolbar giving you?
This can be solved by adding your own title (and subtitle, if you need it) text views inside the toolbar alongside your custom view.
But perhaps a better way is to use a second toolbar nested inside the first. That way, all formatting is taken care of for you.
