I use the Toolbar as an ActionBar. I can set a subtitle, however is it possible to have e.g. an ImageView as a subtitle instead of text only?
The Toolbar is just a ViewGroup,so you can define your favorite views inside it.
For example:
<android.support.v7.widget.Toolbar
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:id="#+id/toolbar"
android:minHeight="?attr/actionBarSize">
<LinearLayout
android:layout_height="match_parent"
android:layout_width="match_parent"
android:orientation="vertical">
<TextView android:id="#+id/textView"..../>
<ImageView
android:id="#+id/imageView"
android:layout_height="wrap_content"
android:layout_width="wrap_content" />
</LinearLayout>
</<android.support.v7.widget.Toolbar>
Then in your code:
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
TextView title = mToolbar.findViewById(R.id.textView);
ImageView image = mToolbar.findViewById(R.id.imageView);
Toolbar behaves just like any other view. So you could into the xml definition of the toolbar, split it vertically (with weight sum) to accommodate your ImageView container, and place an ImageView there.
Then, in your Activity, you could set the image:
ImageView subtitleImage = mToolbar.findViewById(R.id.subtitle_imageview);
subtitleImage.setImageResource(R.drawable.your_image_view);

I have a lot of different titles for Toolbar that I pass from previous activity trough intent:
title = getIntent().getStringExtra("title");
And I set them to my Toolbar of new activity like this:
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setDisplayShowTitleEnabled(true);
getSupportActionBar().setTitle(title);
But the font is too large and only covers one line of toolbar:
This is one of the example titles:
CONVERSION OF RADAR RANGE PROPAGATION KILOMETER INTO MICROSECOND TIME AND VICE-VERSA
I would like to know is there a way to dynamically change Toolbar height and text size to fit this titles? Can this be done programmatically?
Thanks
try this create custom toolbar like this
<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">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center"
android:orientation="vertical">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Did you know"
android:id="#+id/myTitle"
android:textColor="#android:color/white" />
</LinearLayout>
</android.support.v7.widget.Toolbar>
and use theme of your activity as NoActionBar
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
TextView myTitle = (TextView) toolbar.findViewById(R.id.myTitle);
You can try like this:
<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>
and in java file;
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar_top);
TextView mTitle = (TextView) toolbarTop.findViewById(R.id.toolbar_title);
I have a toolbar in my xml file, with no child views defined in it. I want to add a TextView on exact location of default title in toolbar when we call setSupportActionBar(toolbar). On particular events, I like to fade in or out these two views in case of particular events.
I tried to do the following in onCreate() of the activity, but nothing is visible except the default title in toolbar.
TextView tv = new TextView(this);
tv.setLayoutParams(toolbarTitle.getLayoutParams());
tv.setHeight(toolbarTitle.getHeight());
tv.setWidth(toolbarTitle.getWidth());
tv.setText("Other Title");
tv.setLeft(toolbarTitle.getLeft());
toolbar.addView(tv);
I also tried to add a RelativeLayout inside the toolbar with width and height set to match parent, but this time, default title TextView of toolbar disappears.
How can add another TextView on exact location of default title TextView in toolbar?
You can use AppBarLayout as below
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.AppBarLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/toolbar_layout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
>
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
>
<TextView
android:id="#+id/toolbar_title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/aadhaar_sign_up"
android:textColor="#color/white"
android:textSize="18.0sp"
app:fontName="Font-Medium.ttf"
/>
</android.support.v7.widget.Toolbar>
</android.support.design.widget.AppBarLayout>
Then you use the textview as below
Toolbar toolbar = (Toolbar) getActivity().findViewById(R.id.toolbar);
((TextView) toolbar.findViewById(R.id.toolbar_title)).setText(title);
I disable title in toolbar using getSupportActionBar().setDisplayShowTitleEnabled(false) in onCreate() method of my activity and put two overlapping textViews encapsulating them with relativeLayout inside toolbar in layout. Then I animate them as I want. While changing text, I used titleTextView.setText() rather then toolbar.setTitle() method.
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 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.
