I'm adding a toolbar in one activity but the toolbar is placed by giving some space from the top left and right. How can I fill the toolbar completely below the status bar?I have give my output screen
Remove the margin if it is set on the toolbar.
ex:-
<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"/>
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"?>

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 trying to set the AppBarLayout's primary color programmatically. The XML layout is AndroidStudio's Scrolling sample:
<android.support.design.widget.AppBarLayout android:id="#+id/app_bar"
android:fitsSystemWindows="true" android:layout_height="#dimen/app_bar_height"
android:layout_width="match_parent" android:theme="#style/AppTheme.AppBarOverlay">
<android.support.design.widget.CollapsingToolbarLayout android:id="#+id/toolbar_layout"
android:fitsSystemWindows="true" android:layout_width="match_parent"
android:layout_height="match_parent" app:layout_scrollFlags="scroll|exitUntilCollapsed"
app:contentScrim="?attr/colorPrimary">
<android.support.v7.widget.Toolbar android:id="#+id/toolbar"
android:layout_height="?attr/actionBarSize" android:layout_width="match_parent"
app:layout_collapseMode="pin" app:popupTheme="#style/AppTheme.PopupOverlay" />
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
And in the activity, I want all items inside the AppBarLayout to have a yellow background, so I'm setting:
int barColor = Color.parseColor("#FFC107");
AppBarLayout barLayout = (AppBarLayout) this.findViewById(R.id.app_bar);
if (barLayout != null) {
barLayout.setBackgroundColor(barColor);
}
toolbar.setBackgroundColor(barColor);
CollapsingToolbarLayout collapsingToolbarLayout = (CollapsingToolbarLayout) this.findViewById(R.id.toolbar_layout);
if (collapsingToolbarLayout != null) {
collapsingToolbarLayout.setBackgroundColor(barColor);
collapsingToolbarLayout.setContentScrimColor(barColor);
}
Everything works fine, except when I'm halfway through scrolling the toolbar (in the exact point where the FAB disappears). In that state, the toolbar's color is still the default primary color (blue, not yellow), like in this image:
So, two questions:
Am I missing a method call?
Any tips on debugging these scenarios? In Android Device Monitor's view hierarchy dump I can't tell which one is the view that's tinted with this color.
I was having the same problem, you have to set the statusBar scrim color as well:
int red = ContextCompat.getColor(activity, R.color.red);
collapsingToolbar.setBackgroundColor(red);
collapsingToolbar.setContentScrimColor(red);
collapsingToolbar.setStatusBarScrimColor(red);
you can even get the color directly using:
collapsingToolbar.setBackgroundResource(R.color.red);
collapsingToolbar.setContentScrimResource(R.color.red);
collapsingToolbar.setStatusBarScrimResource(R.color.red);
So I'm creating a Material design app for Android. I'm using the new Toolbar instead of using an ActionBar. In one activity, I want to display tabs below the toolbar. This works for both portrait and landscape mode alike, but in landscape mode, the tabs are centered and do not cover the entire width of the view.
Is this by design or is there something I need to know?
This is the layout for my activity:
<android.support.design.widget.AppBarLayout
android:layout_height="wrap_content"
android:layout_width="match_parent">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:height="?attr/actionBarSize"
android:background="#color/primary"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"
app:titleTextAppearance="#style/ToolbarTitle"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light">
</android.support.v7.widget.Toolbar>
<android.support.design.widget.TabLayout
android:id="#+id/toolbar_tabs"
android:height="?attr/actionBarSize"
android:background="#color/primary"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:layout_scrollFlags="scroll|enterAlways" />
</android.support.design.widget.AppBarLayout>
The following code initializes this in onCreate:
// Set up the toolbar
this.setSupportActionBar(mToolbar);
ActionBar ab = this.getSupportActionBar();
if (ab != null)
{
ab.setDisplayHomeAsUpEnabled(true);
ab.setHomeButtonEnabled(true);
ab.setDisplayShowTitleEnabled(true);
}
// Set up the pager and tabs from the pager
mTabViewPager.setAdapter(mTabPagerAdapter);
mTabLayout.setupWithViewPager(mTabViewPager);
The mTabPagerAdapter is a pager adapter that holds the pages to be shown by the tabs as found in the docs.
You can use app:tabGravity="fill" to fit width in entire screen.
<android.support.design.widget.TabLayout
android:id="#+id/tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:tabGravity="fill"
app:tabIndicatorColor="#color/white"
app:tabMode="fixed"
app:tabMaxWidth="0dp"
app:tabSelectedTextColor="#color/white"
app:tabTextColor="#color/white_dim" />`

I want a SearchView to fully take up the full width of the ActionBar (support v7), but even after calling...
actionBar.setHomeButtonEnabled(false);
actionBar.setDisplayShowTitleEnabled(false);
actionBar.setDisplayShowCustomEnabled(false);
actionBar.setDisplayUseLogoEnabled(false);
actionBar.setDisplayShowHomeEnabled(false);
... I get a blank space to the left:
I solved it by using a Toolbar and setting the following paramters:
<android.support.v7.widget.Toolbar
android:id="#+id/tbToolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:paddingLeft="0dp"
android:background="?attr/colorPrimary"
android:contentInsetLeft="0dp"
android:contentInsetStart="0dp"
app:contentInsetLeft="0dp"
app:contentInsetStart="0dp"
app:contentInsetStartWithNavigation="0dp">
Inside that you can put a SearchView or use your toolbar items with a menu.xml which has a toolbarview. See the android developer docs.
