I want to change the overflow menu icons color in my material toolbar depending on the android:theme value.
In this example my search icon is affected by the toolbar's theme via some magic related to the app:actionViewClass attribute implementation, but my info icon is not.
My toolbar:
<?xml version="1.0" encoding="utf-8"?>
<com.google.android.material.appbar.AppBarLayout
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:fitsSystemWindows="true"
app:liftOnScroll="true">
<com.google.android.material.appbar.MaterialToolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:theme="#style/ThemeOverlay.MaterialComponents.Dark.ActionBar"
style="#style/Widget.MaterialComponents.Toolbar.Primary"
app:title="#string/app_name"
app:menu="#menu/menu_main"
app:layout_scrollFlags="scroll|enterAlways|snap"/>
</com.google.android.material.appbar.AppBarLayout>
My menu:
<?xml version="1.0" encoding="utf-8"?>
<menu
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<item
android:id="#+id/action_search"
android:icon="#drawable/ic_search_24dp"
app:showAsAction="always"
app:actionViewClass="androidx.appcompat.widget.SearchView"
android:title="TODO" />
<item android:id="#+id/action_info"
android:icon="#drawable/ic_info_24dp"
app:showAsAction="always"
android:title="TODO" />
</menu>
Does a simple solution exists?
You can use:
<com.google.android.material.appbar.MaterialToolbar
style="#style/Widget.MaterialComponents.Toolbar.Primary"
android:theme="#style/MyThemeOverlay_Toolbar"
...>
<style name="MyThemeOverlay_Toolbar" parent="ThemeOverlay.MaterialComponents.Toolbar.Primary">
<!-- color used by navigation icon and overflow icon -->
<item name="colorOnPrimary">#color/myColor</item>
</style>
You can head over to the Material Components documentation which has a lot of information about styling each part of views from the library.
In this case it seems like the action icon tint is set by the colorControlNormal attribute.
Documentation - Top app bars
Maybe this answer comes too late, but just in case other people need it, I will post my answer here.
The problem you are facing will be solved if you set the attribute theme to the AppBarLayout instead of the MaterialToolbar.
So, in your code, your toolbar should look like this:
<?xml version="1.0" encoding="utf-8"?>
<com.google.android.material.appbar.AppBarLayout
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:fitsSystemWindows="true"
android:theme="#style/ThemeOverlay.MaterialComponents.Dark.ActionBar"
app:liftOnScroll="true">
<com.google.android.material.appbar.MaterialToolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
style="#style/Widget.MaterialComponents.Toolbar.Primary"
app:title="#string/app_name"
app:menu="#menu/menu_main"
app:layout_scrollFlags="scroll|enterAlways|snap"/>
</com.google.android.material.appbar.AppBarLayout>
Hope this helps to anyone!
I'd like to integrate something like this:
And I've done it like this, but I can't seem to put the imageview below the toolbar. Without the toolbar, I can make it under the status bar, but combining these two are impossible.
Here's my layout:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:fitsSystemWindows="true"
tools:context="com.project.android.PhotoActivity">
<android.support.v7.widget.Toolbar
android:id="#+id/photo_tl"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="#59000000"
tools:ignore="UnusedAttribute" />
<ImageView
android:id="#+id/photo_image"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:adjustViewBounds="true"
android:scaleType="fitStart" />
</LinearLayout>
In my activity, I've done the following:
getWindow().getDecorView().setSystemUiVisibility(
View.SYSTEM_UI_FLAG_LAYOUT_STABLE
| View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN);
I've also declared an styles-v21.xml file:
<style name="Project.Photo" parent="Project.Light">
<item name="android:windowDrawsSystemBarBackgrounds">true</item>
<item name="android:statusBarColor">#59000000</item>
</style>
And set it as default style for PhotoActivity.
I've already tried putting the toolbar in a FrameLayout, but doing that my toolbar simply hides, like this:
Thanks in advance.
Got that fixed, but toolbar is overlapping the status bar. Is there anyway to fix the padding? If I use android:fitsSystemWindows="true", status bar isn't translucent anymore.
I would remove the Toolbar from your layout and use an implementation of an ActionBar from the AppCompat.Theme:
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<item name="colorPrimary">#color/colorPrimary</item>
<item name="colorPrimaryDark">#color/colorPrimaryDark</item>
<item name="colorAccent">#color/colorAccent</item>
</style>
Then, I would create a new style for the semi-transparent ActionBar (in values/styles.xml:
<style name="AppTheme.Transparent" parent="AppTheme">
<item name="windowActionBarOverlay">true</item>
</style>
And in v21/styles.xml:
<style name="AppTheme.Transparent" parent="AppTheme">
<item name="windowActionBarOverlay">true</item>
<item name="android:windowTranslucentStatus">true</item>
</style>
I assume, that your Activity extends AppCompatActivity so then in onCreate() you can call:
For enabling a back button:
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setHomeButtonEnabled(true);
For setting your translucent color:
getSupportActionBar().setBackgroundDrawable(new ColorDrawable(ContextCompat.getColor(this, R.color.yourTranslucentColor)));
For removing your ActionBar title:
getSupportActionBar().setDisplayShowTitleEnabled(false);
What is more, I would change your root LinearLayout to CoordinatorLayout as it gives you more control over your layouts (it's a more powerful FrameLayout).
The color which I used is:
<color name="yourTranslucentColor">#29000000</color>
Of course you should remember to apply this theme to your Activity in the AndroidManifest.xml:
<activity
android:name=".ui.activity.YourActivity"
android:theme="#style/AppTheme.Transparent">
</activity>
By doing all these steps you should get something like this:
Please let me know, if it works for you.
As you said,
"I've already tried putting the toolbar in a FrameLayout, but doing that my toolbar simply hides, like this:".
The problem with this is the order of adding childView in FrameLayout, you added Toolbar as first child and after that you added ImageView. this is why image hides the toolbar. Instead, the order of views inside FameLayout should be like this
<FrameLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:context="com.project.android.PhotoActivity">
<ImageView
android:id="#+id/photo_image"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:adjustViewBounds="true"
android:scaleType="fitStart" />
<android.support.v7.widget.Toolbar
android:id="#+id/photo_tl"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="#59000000"
tools:ignore="UnusedAttribute" />
</FrameLayout>
Also for API level >=19 ,you can add this attribute in style.xml file to make statusBar transparent
<item name="android:windowTranslucentStatus">true</item>
For making content behind statusBar use this link
https://developer.android.com/training/system-ui/status.html#behind
Use code below
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/coordinator_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true">
<android.support.design.widget.AppBarLayout
android:id="#+id/appbar"
android:layout_width="match_parent"
android:layout_height="300dp"
android:fitsSystemWindows="true">
<android.support.design.widget.CollapsingToolbarLayout
android:id="#+id/collapsing_toolbar"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
app:contentScrim="#color/colorPrimary"
app:expandedTitleMarginEnd="64dp"
app:expandedTitleMarginStart="48dp"
app:expandedTitleTextAppearance="#style/AppTheme.CollapsingToolbarLayoutExpandedTextStyle"
app:layout_scrollFlags="scroll|exitUntilCollapsed">
<ImageView
android:id="#+id/iv_backdrop"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
android:scaleType="centerCrop"
app:layout_collapseMode="parallax" />
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?android:attr/actionBarSize"
android:theme="#style/YourTheme"
app:layout_collapseMode="pin" />
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
<!-- Rest of your view-->
</android.support.design.widget.CoordinatorLayout>
LinearLayout will automatically place the ImageView below the Toolbar.
Try using a RelativeLayout instead.
Dont treat status bar as something separate from your app. Image is coming below the toolbar because you have used LinearLayout. Had you used RelativeLayout, your image would be starting at the same height as toolbar.
Now for making the statusbar transparent and for everything to start from under the statusbar use the following.
<style name="AppTheme.TranslucentStatusBar" >
<item name="android:windowTranslucentStatus">true</item>
<item name="android:windowBackground">#android:color/transparent</item>
</style>
Use the above style for your activity and everything starts from under the statusbar. Now for the toolbar, you can increase the height of the toolbar by adding the height of the statusbar as padding to toolbar. This can be done as follows:
toolbarContainer.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
#Override
public void onGlobalLayout() {
Rect frame = new Rect();
getWindow().getDecorView().getWindowVisibleDisplayFrame(frame);
toolbarContainer.setPadding(0, frame.top, 0, 0);
}
});
You can set a color to statusbar and use the same color with AlphaTransparency on Toolbar.
getWindow().setStatusBarColor(ContextCompat.getColor(this, android.R.color.transparent));
Now you control everything including the statusbar and the toolbar.
Got that fixed, but toolbar is overlapping the status bar. Is there anyway to fix the padding? If I use android:fitsSystemWindows="true", status bar isn't translucent anymore.
I've recently written a post about WindowInsets, you may check it out. I think it would resolve your issue.
Long story short - what you have to do is to pass window insets only to Toolbar via ViewCompat.setOnApplyWindowInsetListener API. But the parent of your Toolbar should pass the window insets. In your case that won't happen, because by default LinearLayout and family layouts won't do that, you have to subclass and override onApplyWindowInsets method.
I suggest you to read the article, where everything is described more precisely.
TLDR; You have to wrap the toolbar in a LinearLayout.
What I did to make it work was similar to #Akhilesh Kumar's approach but I wrapped the toolbar in a LinearLayout which fixed the toolbar overlapping. I also put the fitsSystemWindows to true in that LinearLayout.
<FrameLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:context="com.project.android.PhotoActivity">
<ImageView
android:id="#+id/photo_image"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:adjustViewBounds="true"
android:scaleType="fitStart"/>
<LinearLayout
android:id="#+id/content_card_image"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:fitsSystemWindows="true"
>
<android.support.v7.widget.Toolbar
android:id="#+id/photo_tl"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="#59000000"
tools:ignore="UnusedAttribute"/>
</LinearLayout>
</FrameLayout>
I hope it helps.
just change the toolbar height to wrap_content:
<android.support.v7.widget.Toolbar
android:id="#+id/photo_tl"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#59000000"
tools:ignore="UnusedAttribute" />
It is self Q&A post
I have transparent ActionBar which overlays layout. After migration to the latest support library I have been forced to get rid off the ActionBar in favor of the Toolbar. The old ways to make it transparent and overlay that layout doesn't work anymore.
<style name="CustomActionBarTheme" parent="#android:style/Theme.AppCompat">
<item name="android:windowActionBarOverlay">true</item>
<item name="windowActionBarOverlay">true</item>
<item name="android:actionBarStyle">#style/TransparentActionBar</item>
</style>
<style name="TransparentActionBar" parent="#android:style/Widget.Holo.Light.ActionBar">
<item name="android:background">#android:color/transparent</item>
</style>
Create your toolbar.xml file with background of AppBarLayout is #null
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.AppBarLayout
android:id="#+id/general_appbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#null"
xmlns:android="http://schemas.android.com/apk/res/android">
<android.support.v7.widget.Toolbar
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize">
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center_horizontal"
android:text="Login"
android:textSize="20sp"/>
</android.support.v7.widget.Toolbar>
</android.support.design.widget.AppBarLayout>
and here is result:
All you need to is to define theme which hide action bar, define action bar style with transparent background and set this style to the toolbar widget. Please note that toolbar should be drawen as last view (over all view tree)
<style name="Theme.Custom" parent="#android:style/Theme.AppCompat">
<item name="windowActionBar">false</item>
<item name="windowActionBarOverlay">true</item>
<item name="android:windowActionBarOverlay">true</item>
</style>
<style name="CustomActionBar" parent="#style/ThemeOverlay.AppCompat.Dark.ActionBar">
<item name="android:windowActionBarOverlay">true</item>
<!-- Support library compatibility -->
<item name="windowActionBarOverlay">true</item>
</style>
Layout:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<!-- Toolbar should be above content-->
<include layout="#layout/toolbar" />
</RelativeLayout>
Toolbar layout:
<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"
app:theme="#style/CustomActionBar"/>
Checking Google's example Source Code I found out how to make the toolbar completely transparent. It was simpler than I thought. We just have to create a simple Shape drawable like this.
The name of the drawable is toolbar_bg
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" >
<gradient
android:angle="90"
android:startColor="#android:color/transparent"
android:endColor="#android:color/transparent"
android:type="linear" />
</shape>
And then in the fragment or activity.. Add the toolbar like this.
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:layout_alignParentStart="true"
android:layout_alignParentTop="true"
android:background="#drawable/toolbar_bg"
android:popupTheme="#style/ThemeOverlay.AppCompat.Light"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"/>
And here we will have a fully transparent toolbar.
Don't add the <android.support.design.widget.AppBarLayout > if you do, this won't work.
Note: If you need the AppBarLayout, set the elevation to 0 so it doesn't draw its shadow.
The Toolbar works like a View, so the answer it's very simple.
toolbar.getBackground().setAlpha(0);
Only this worked for me (AndroidX support library):
<com.google.android.material.appbar.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#null"
android:theme="#style/AppTheme.AppBarOverlay"
android:translationZ="0.1dp"
app:elevation="0dp">
<androidx.appcompat.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="#null"
app:popupTheme="#style/AppTheme.PopupOverlay" />
</com.google.android.material.appbar.AppBarLayout>
This code removes background in all necessary views and also removes shadow from AppBarLayout (which was a problem)
Answer was found here: remove shadow below AppBarLayout widget android
Add the following line in style.xml
<style name="Base.Theme.AppTheme" parent="Theme.AppCompat.DayNight.NoActionBar">
<item name="colorPrimary">#color/colorPrimary</item>
<item name="colorPrimaryDark">#color/colorPrimaryDark</item>
<item name="colorAccent">#color/colorAccent</item>
</style>
<style name="AppTheme" parent="Base.Theme.AppTheme">
</style>
Now add the following line in style-v21,
<style name="AppTheme" parent="Base.Theme.AppTheme">
<item name="android:windowDrawsSystemBarBackgrounds">true</item>
<item name="android:statusBarColor">#android:color/transparent</item>
</style>
and set the theme as
android:theme="#style/AppTheme"
It will make the status bar transparent.
Just add android:background="#android:color/transparent" like below in your appbar layout
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#android:color/transparent">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:popupTheme="#style/AppTheme.PopupOverlay" />
</android.support.design.widget.AppBarLayout>`
Just use the following xml code:
Code for the layout:
<android.support.v7.widget.Toolbar
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/def_toolbar"
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:minHeight="?attr/actionBarSize"
android:background="#color/toolbarTransparent"
android:layout_alignParentTop="true" />
And add the following code in the colors.xml:
<color name="toolbarTransparent">#00FFFFFF</color>
This will give you the desired output.
Perhaps you need to take a look at this post transparent Actionbar with AppCompat-v7 21
Points that the post suggest are
Just ensure that you use RelativeLayout to lay Toolbar and the body.
Put the Toolbar in the last.
Put transparent color for android:background attribute of the Toolbar
This should solve the problem without too much hassle.
The simplest way to put a Toolbar transparent is to define a opacity in #colors section, define a TransparentTheme in #styles section and then put these defines in your toolbar.
#colors.xml
<color name="actionbar_opacity">#33000000</color>
#styles.xml
<style name="TransparentToolbar" parent="#style/ThemeOverlay.AppCompat.Dark.ActionBar">
<item name="android:windowActionBarOverlay">true</item>
<item name="windowActionBarOverlay">true</item>
</style>
#activity_main.xml
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:background="#color/actionbar_opacity"
app:theme="#style/TransparentToolbar"
android:layout_height="?attr/actionBarSize"/>
That's the result:
Screenshot transparent toolbar
I implemented translucent Toolbar by creating two Theme.AppCompat.Light.NoActionBar themes and setting colorPrimary attribute to transparent color.
1) Create one theme for opaque Toolbar:
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
<!-- Toolbar background color -->
<item name="colorPrimary">#ff212cff</item>
</style>
Second theme for transparent/overlay Toolbar:
<style name="AppTheme.Overlay" parent="AppTheme">
<item name="colorPrimary">#color/transparent</item>
</style>
2) In your activity layout, put Toolbar behind content so it can be displayed in front of it:
<RelativeLayout
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:orientation="vertical">
<fragment
android:id="#+id/container"
android:name="com.test.CustomFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="?attr/colorPrimary"
android:minHeight="?attr/actionBarSize"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light"
app:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"/>
</RelativeLayout>
3)
Apply the transparent theme to your acivity in AndroidManifest.xml
<activity
android:name="com.test.TransparentActivity"
android:parentActivityName="com.test.HomeActivity"
android:theme="#style/AppTheme.Overlay" >
<meta-data
android:name="android.support.PARENT_ACTIVITY"
android:value="com.test.HomeActivity" />
</activity>
I know am late for the party. I've created a simple class to manage the Toolbar transparency.
import android.annotation.SuppressLint;
import android.graphics.drawable.ColorDrawable;
import android.support.v7.widget.Toolbar;
public class TransparentToolbarManager {
private Toolbar mToolbar;
private ColorDrawable colorDrawable;
public static final int MAX_ALPHA = 255, MIN_ALPHA = 0;
public TransparentToolbarManager(Toolbar mToolbar) {
this.mToolbar = mToolbar;
this.colorDrawable = new ColorDrawable(mToolbar.getContext().getResources().getColor(R.color.colorPrimary));
}
public TransparentToolbarManager(Toolbar mToolbar, ColorDrawable colorDrawable) {
this.mToolbar = mToolbar;
this.colorDrawable = colorDrawable;
}
//Fading toolbar
public void manageFadingToolbar(int scrollDistance) {
if (mToolbar != null && colorDrawable != null) {
//FadeinAndOut according to the horizontal scrollValue
if (scrollDistance <= MAX_ALPHA && scrollDistance >= MIN_ALPHA) {
setToolbarAlpha(scrollDistance);
} else if (scrollDistance > MAX_ALPHA) {
setToolbarAlpha(MAX_ALPHA);
}
}
}
#SuppressLint("NewApi")
public void setToolbarAlpha(int i) {
colorDrawable.setAlpha(i);
if (CommonHelper.isSupport(16)) {
mToolbar.setBackground(colorDrawable);
} else {
mToolbar.setBackgroundDrawable(colorDrawable);
}
}
}
and the CommonHelper.isSupport()
public static boolean isSupport(int apiLevel) {
return Build.VERSION.SDK_INT >= apiLevel;
}
Just Add android:background="#10000000" in your AppBarLayout tag It works
https://stackoverflow.com/a/37672153/2914140 helped me.
I made this layout for an activity:
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_height="wrap_content"
android:background="#color/transparent" <- Add transparent color in AppBarLayout.
android:theme="#style/AppTheme.AppBarOverlay"

<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?android:attr/actionBarSize"

android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent"
<- Remove app:layout_behavior=...
/>
</android.support.design.widget.CoordinatorLayout>
If this doesn't work, in onCreate() of the activity write (where toolbar is #+id/toolbar):
toolbar.background.alpha = 0
If you want to set a semi-transparent color (like #30ff00ff), then set toolbar.setBackgroundColor(color). Or even set a background color of AppBarLayout.
In my case styles of AppBarLayout and Toolbar didn't play role.
try below code
<android.support.design.widget.AppBarLayout
android:id="#+id/app_bar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/AppTheme.Transparent"

<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:popupTheme="#style/AppTheme.PopupOverlay" />
</android.support.design.widget.AppBarLayout>

Don't forget to write: android:background="#android:color/transparent"
Go to res package and open color.xml.
Set color primary to #00000000.
I'm using a template from Android Studio that used AppCompat Toolbar. Unfortunately, the toolbar casts shadow on the status bar so it doesn't look right.I also implement a NavigationDrawer so I can't simply set the color of the status bar.
This is how it looks:
This is how it should be:

This shadow is part of windowContentOverlay on APIs below LOLLIPOP (on LOLLIPOP it's #null).
When you work with Toolbar widget the toolbar isn't part of window decor anymore so the shadow starts at the top of the window over the toolbar instead of below it (so you want the windowContentOverlay to be #null). Additionally you need to add an extra empty View below the toolbar pre-LOLLIPOP with its background set to a vertical shadow drawable (8dp tall gradient from #20000000 to #00000000 works best). On LOLLIPOP you can set 8dp elevation on the toolbar instead.
I tried all the other answers and none worked. What fixed it was adding this to the AppBarLayout:
app:elevation="0dp"
That's because of :
<item name="android:statusBarColor">#android:color/transparent</item>
i guess.
Got it, check this:
http://developer.android.com/training/material/theme.html#StatusBar
To set a custom color for the status bar, use the
android:statusBarColor attribute when you extend the material theme.
By default, android:statusBarColor inherits the value of
android:colorPrimaryDark.
And you've set it to transparent.this is not a good way for doing that since Google put this code for you:
<item name="colorPrimaryDark">#color/colorPrimaryDark</item>
And also, instead of:
<style name="AppTheme.NoActionBar">
Use this and add a parent and check:
<style name="AppTheme.NoActionBar" parent="Theme.AppCompat.Light.NoActionBar">
To get the correct behavior, you will need to remove
android:fitsSystemWindows="true"
From android.support.design.widget.CoordinatorLayout
In your styles.xml, color defined in colorPrimaryDarkwill be used for drawing the notification bar.
You will need to have styles.xml in your values-v21 folder with following item in your styles:
<item name="android:statusBarColor">#android:color/transparent</item>
Hope this helps.
It is self Q&A post
I have transparent ActionBar which overlays layout. After migration to the latest support library I have been forced to get rid off the ActionBar in favor of the Toolbar. The old ways to make it transparent and overlay that layout doesn't work anymore.
<style name="CustomActionBarTheme" parent="#android:style/Theme.AppCompat">
<item name="android:windowActionBarOverlay">true</item>
<item name="windowActionBarOverlay">true</item>
<item name="android:actionBarStyle">#style/TransparentActionBar</item>
</style>
<style name="TransparentActionBar" parent="#android:style/Widget.Holo.Light.ActionBar">
<item name="android:background">#android:color/transparent</item>
</style>
Create your toolbar.xml file with background of AppBarLayout is #null
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.AppBarLayout
android:id="#+id/general_appbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#null"
xmlns:android="http://schemas.android.com/apk/res/android">
<android.support.v7.widget.Toolbar
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize">
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center_horizontal"
android:text="Login"
android:textSize="20sp"/>
</android.support.v7.widget.Toolbar>
</android.support.design.widget.AppBarLayout>
and here is result:
All you need to is to define theme which hide action bar, define action bar style with transparent background and set this style to the toolbar widget. Please note that toolbar should be drawen as last view (over all view tree)
<style name="Theme.Custom" parent="#android:style/Theme.AppCompat">
<item name="windowActionBar">false</item>
<item name="windowActionBarOverlay">true</item>
<item name="android:windowActionBarOverlay">true</item>
</style>
<style name="CustomActionBar" parent="#style/ThemeOverlay.AppCompat.Dark.ActionBar">
<item name="android:windowActionBarOverlay">true</item>
<!-- Support library compatibility -->
<item name="windowActionBarOverlay">true</item>
</style>
Layout:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<!-- Toolbar should be above content-->
<include layout="#layout/toolbar" />
</RelativeLayout>
Toolbar layout:
<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"
app:theme="#style/CustomActionBar"/>
Checking Google's example Source Code I found out how to make the toolbar completely transparent. It was simpler than I thought. We just have to create a simple Shape drawable like this.
The name of the drawable is toolbar_bg
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" >
<gradient
android:angle="90"
android:startColor="#android:color/transparent"
android:endColor="#android:color/transparent"
android:type="linear" />
</shape>
And then in the fragment or activity.. Add the toolbar like this.
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:layout_alignParentStart="true"
android:layout_alignParentTop="true"
android:background="#drawable/toolbar_bg"
android:popupTheme="#style/ThemeOverlay.AppCompat.Light"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"/>
And here we will have a fully transparent toolbar.
Don't add the <android.support.design.widget.AppBarLayout > if you do, this won't work.
Note: If you need the AppBarLayout, set the elevation to 0 so it doesn't draw its shadow.
The Toolbar works like a View, so the answer it's very simple.
toolbar.getBackground().setAlpha(0);
Only this worked for me (AndroidX support library):
<com.google.android.material.appbar.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#null"
android:theme="#style/AppTheme.AppBarOverlay"
android:translationZ="0.1dp"
app:elevation="0dp">
<androidx.appcompat.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="#null"
app:popupTheme="#style/AppTheme.PopupOverlay" />
</com.google.android.material.appbar.AppBarLayout>
This code removes background in all necessary views and also removes shadow from AppBarLayout (which was a problem)
Answer was found here: remove shadow below AppBarLayout widget android
Add the following line in style.xml
<style name="Base.Theme.AppTheme" parent="Theme.AppCompat.DayNight.NoActionBar">
<item name="colorPrimary">#color/colorPrimary</item>
<item name="colorPrimaryDark">#color/colorPrimaryDark</item>
<item name="colorAccent">#color/colorAccent</item>
</style>
<style name="AppTheme" parent="Base.Theme.AppTheme">
</style>
Now add the following line in style-v21,
<style name="AppTheme" parent="Base.Theme.AppTheme">
<item name="android:windowDrawsSystemBarBackgrounds">true</item>
<item name="android:statusBarColor">#android:color/transparent</item>
</style>
and set the theme as
android:theme="#style/AppTheme"
It will make the status bar transparent.
Just add android:background="#android:color/transparent" like below in your appbar layout
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#android:color/transparent">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:popupTheme="#style/AppTheme.PopupOverlay" />
</android.support.design.widget.AppBarLayout>`
Just use the following xml code:
Code for the layout:
<android.support.v7.widget.Toolbar
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/def_toolbar"
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:minHeight="?attr/actionBarSize"
android:background="#color/toolbarTransparent"
android:layout_alignParentTop="true" />
And add the following code in the colors.xml:
<color name="toolbarTransparent">#00FFFFFF</color>
This will give you the desired output.
Perhaps you need to take a look at this post transparent Actionbar with AppCompat-v7 21
Points that the post suggest are
Just ensure that you use RelativeLayout to lay Toolbar and the body.
Put the Toolbar in the last.
Put transparent color for android:background attribute of the Toolbar
This should solve the problem without too much hassle.
The simplest way to put a Toolbar transparent is to define a opacity in #colors section, define a TransparentTheme in #styles section and then put these defines in your toolbar.
#colors.xml
<color name="actionbar_opacity">#33000000</color>
#styles.xml
<style name="TransparentToolbar" parent="#style/ThemeOverlay.AppCompat.Dark.ActionBar">
<item name="android:windowActionBarOverlay">true</item>
<item name="windowActionBarOverlay">true</item>
</style>
#activity_main.xml
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:background="#color/actionbar_opacity"
app:theme="#style/TransparentToolbar"
android:layout_height="?attr/actionBarSize"/>
That's the result:
Screenshot transparent toolbar
I implemented translucent Toolbar by creating two Theme.AppCompat.Light.NoActionBar themes and setting colorPrimary attribute to transparent color.
1) Create one theme for opaque Toolbar:
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
<!-- Toolbar background color -->
<item name="colorPrimary">#ff212cff</item>
</style>
Second theme for transparent/overlay Toolbar:
<style name="AppTheme.Overlay" parent="AppTheme">
<item name="colorPrimary">#color/transparent</item>
</style>
2) In your activity layout, put Toolbar behind content so it can be displayed in front of it:
<RelativeLayout
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:orientation="vertical">
<fragment
android:id="#+id/container"
android:name="com.test.CustomFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="?attr/colorPrimary"
android:minHeight="?attr/actionBarSize"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light"
app:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"/>
</RelativeLayout>
3)
Apply the transparent theme to your acivity in AndroidManifest.xml
<activity
android:name="com.test.TransparentActivity"
android:parentActivityName="com.test.HomeActivity"
android:theme="#style/AppTheme.Overlay" >
<meta-data
android:name="android.support.PARENT_ACTIVITY"
android:value="com.test.HomeActivity" />
</activity>
I know am late for the party. I've created a simple class to manage the Toolbar transparency.
import android.annotation.SuppressLint;
import android.graphics.drawable.ColorDrawable;
import android.support.v7.widget.Toolbar;
public class TransparentToolbarManager {
private Toolbar mToolbar;
private ColorDrawable colorDrawable;
public static final int MAX_ALPHA = 255, MIN_ALPHA = 0;
public TransparentToolbarManager(Toolbar mToolbar) {
this.mToolbar = mToolbar;
this.colorDrawable = new ColorDrawable(mToolbar.getContext().getResources().getColor(R.color.colorPrimary));
}
public TransparentToolbarManager(Toolbar mToolbar, ColorDrawable colorDrawable) {
this.mToolbar = mToolbar;
this.colorDrawable = colorDrawable;
}
//Fading toolbar
public void manageFadingToolbar(int scrollDistance) {
if (mToolbar != null && colorDrawable != null) {
//FadeinAndOut according to the horizontal scrollValue
if (scrollDistance <= MAX_ALPHA && scrollDistance >= MIN_ALPHA) {
setToolbarAlpha(scrollDistance);
} else if (scrollDistance > MAX_ALPHA) {
setToolbarAlpha(MAX_ALPHA);
}
}
}
#SuppressLint("NewApi")
public void setToolbarAlpha(int i) {
colorDrawable.setAlpha(i);
if (CommonHelper.isSupport(16)) {
mToolbar.setBackground(colorDrawable);
} else {
mToolbar.setBackgroundDrawable(colorDrawable);
}
}
}
and the CommonHelper.isSupport()
public static boolean isSupport(int apiLevel) {
return Build.VERSION.SDK_INT >= apiLevel;
}
Just Add android:background="#10000000" in your AppBarLayout tag It works
https://stackoverflow.com/a/37672153/2914140 helped me.
I made this layout for an activity:
<?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"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
>
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#color/transparent" <- Add transparent color in AppBarLayout.
android:theme="#style/AppTheme.AppBarOverlay"
>
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?android:attr/actionBarSize"
android:theme="#style/ToolbarTheme"
app:popupTheme="#style/AppTheme.PopupOverlay"
app:theme="#style/ToolbarTheme"
/>
</android.support.design.widget.AppBarLayout>
<FrameLayout
android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent"
<- Remove app:layout_behavior=...
/>
</android.support.design.widget.CoordinatorLayout>
If this doesn't work, in onCreate() of the activity write (where toolbar is #+id/toolbar):
toolbar.background.alpha = 0
If you want to set a semi-transparent color (like #30ff00ff), then set toolbar.setBackgroundColor(color). Or even set a background color of AppBarLayout.
In my case styles of AppBarLayout and Toolbar didn't play role.
try below code
<android.support.design.widget.AppBarLayout
android:id="#+id/app_bar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/AppTheme.Transparent"
>
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:popupTheme="#style/AppTheme.PopupOverlay" />
</android.support.design.widget.AppBarLayout>
style.xml
<style name="AppTheme.Transparent" parent="ThemeOverlay.AppCompat.Light">
<item name="colorPrimary">#android:color/transparent</item>
<item name="colorControlActivated">#color/colorWhite</item>
<item name="colorControlNormal">#color/colorWhite</item>
</style>
for Support Toolbar v7 android.support.v7.widget.Toolbar:
code
toolbar.setBackground(null);
// or
toolbar.setBackgroundColor(ContextCompat.getColor(getContext(), android.R.color.transparent));
xml (android:background="#null" or android:background="#android:color/transparent")
<android.support.v7.widget.Toolbar
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:background="#null"
android:minHeight="?attr/actionBarSize"
android:theme="#style/Theme.AppCompat.Light.DarkActionBar">
<TextView

android:layout_height="wrap_content"
android:textColor="#android:color/white"
android:ellipsize="start"
android:singleLine="true"
android:textAppearance="#style/TextAppearance.AppCompat.Widget.ActionBar.Title"/>
</android.support.v7.widget.Toolbar>
if Title is invisible, set textColor
Add below code to styles.xml file
<style name="LayoutPageTheme" parent="#style/Theme.AppCompat.Light.NoActionBar">
<item name="android:windowActionBarOverlay">true</item>
<!-- Support library compatibility -->
<item name="windowActionBarOverlay">true</item>

Don't forget to write: android:background="#android:color/transparent"
Go to res package and open color.xml.
Set color primary to #00000000.
