I'm using the AppCompat v21 library to create a Lollipop-like interface in my android app. So far it's working great.
Now I want to have to toolbar appear on top of my content in one of my activities.
However, I cannot get it to work. This is what I have so far:
Layout of activity:
<LinearLayout
android:id="#+id/main_parent_view"
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:theme="#style/myAppTheme">
<include layout="#layout/toolbar_setlist_top"/>
<ImageView
android:id="#+id/image"
android:layout_height="match_parent"
android:layout_width="match_parent"/>
</LinearLayout>
Layout of toolbar:
<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"
app:theme="#style/MyActionBar"
app:popupTheme="#style/MyActionBar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:minHeight="?attr/actionBarSize"
android:layout_marginTop="0dp" />
Theme:
<resources>
<style name="myAppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<item name="colorPrimary">#color/primaryColor</item>
<item name="colorPrimaryDark">#color/primaryColorDark</item>
<item name="android:windowNoTitle">true</item>
<item name="windowActionBar">false</item>
<item name="drawerArrowStyle">#style/DrawerArrowStyle</item>
<item name="android:activatedBackgroundIndicator">#drawable/list_selector</item>
<item name="actionBarStyle">#style/MyActionBar</item>
</style>
<style name="DrawerArrowStyle" parent="Widget.AppCompat.DrawerArrowToggle">
<item name="spinBars">true</item>
<item name="color">#android:color/white</item>
</style>
<style name="MyActionBar" parent="#style/Widget.AppCompat.ActionBar">
<item name="android:background">#color/primaryColor2</item>
<item name="android:windowActionBarOverlay">true</item>
<!-- Support library compatibility -->
<item name="background">#color/primaryColor2</item>
<item name="windowActionBarOverlay">true</item>
</style>
</resources>
Code:
#Override
protected void onCreate(Bundle savedInstanceState) {
requestWindowFeature(Window.FEATURE_ACTION_BAR_OVERLAY);
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_setlist);
toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
}
If you want to place the toolbar on top of your content you can use a FrameLayout like this:
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:id="#+id/main_parent_view"
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<ImageView
android:id="#+id/image"
android:layout_height="100dp"
android:layout_width="40dp"
android:background="#000"/>
</LinearLayout>
<include layout="#layout/toolbar_setlist_top"/>
</FrameLayout>
It doesn't appear that you're acquiring a reference to the toolbar view in your layout anywhere. You need to find the view first, then pass that reference to the setSupportActionBar method:
setContentView(R.layout.activity_setlist);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
Assuming that when you say "Now I want to have to toolbar appear on top of my content in one of my activities" you are trying to use the Toolbar as your activity's ActionBar (instead of the old/original ActionBar) you must make your theme's parent theme "Theme.AppCompat.NoActionBar" instead of your current setting *.Light.DarkActionBar. 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_width="match_parent"
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>
<item name="android:actionBarStyle">#style/TransparentActionBar</item>
</style>
<!-- ActionBar styles -->
<style name="TransparentActionBar"
parent="#android:style/Widget.Holo.Light.ActionBar">
<item name="android:background">#android:color/transparent</item>
</style>
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="#android:color/transparent"
app:popupTheme="#style/AppTheme.PopupOverlay" />
Don't forget to write: android:background="#android:color/transparent"
Go to res package and open color.xml.
Set color primary to #00000000.
I am just starting to learn android, I am learning to add AppBar. But if I use Relative Layout as the root then Status Bar don't use the color "colorPrimaryDark" defined in the theme. But changing the layout to CoordinatorLayout make it works.
Can someone explain the difference? is it a requirement to use the CoordinatorLayout Layout?
Activity Extends AppCompatActivity.

In v21/styles.xml you probably have this line of code:
<item name="android:statusBarColor">#android:color/transparent</item>
And as you are running on API 23, the declared styles are overrided from the ones in v21/styles.xml.
As a solution:
Just remove that line and it will work fine
The styling of the statusbar is done by the
android:fitsSystemWindows
tag. This is currently not supported for RelativeLayout. Either you try another layout like FrameLayout which could work but for know i would suggest to stick to the CoordinatorLayout.
Maybe you get some more details here:
https://medium.com/google-developers/why-would-i-want-to-fitssystemwindows-4e26d9ce1eec
just add this
getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LIGHT_STATUS_BAR);
In the images below,I am trying to bring the ImageView under the StatusBar. But its not happening.
Image Screenshot on Android API 19
Image Screenshot on Android API 22
I went on Android transparent status bar and actionbar (this question) and tried to implement the same but its not working.
The xml layout of the activity is
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout
android:layout_height="match_parent"
android:layout_width="match_parent"
android:fitsSystemWindows="true"
xmlns:android="http://schemas.android.com/apk/res/android">
<LinearLayout
android:id="#+id/category_layout_top"
android:fitsSystemWindows="true"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<ImageView
android:fitsSystemWindows="true"
android:layout_width="390dp"
android:layout_height="390dp"
android:id="#+id/category_Image_View"/>
<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="#00FFFFFF"
android:layout_alignParentTop="true" />
</FrameLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="50dp"
android:id="#+id/category_linearlayout">
<TextView android:layout_width="match_parent"
android:layout_height="match_parent"
android:singleLine="true"
android:id="#+id/category_textView"
/>
</LinearLayout>
</LinearLayout>
</FrameLayout>
I tried the below code in the onCreate() method also
setStatusBarTranslucent(true);
protected void setStatusBarTranslucent(boolean makeTranslucent) {
if (makeTranslucent) {
getWindow().addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
} else {
getWindow().clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
}
}
style.xml
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimary">#color/colorPrimary</item>
<item name="colorPrimaryDark">#color/colorPrimaryDark</item>
<item name="colorAccent">#color/colorAccent</item>
</style>
style-v21.xml
<style name="AppTheme.NoActionBar">
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
<item name="android:windowDrawsSystemBarBackgrounds">true</item>
<item name="android:statusBarColor">#android:color/transparent</item>
</style>
AppTheme is the style used in the activity.
EDIT 1
I used a color in the background of FrameLayout to check whether it was under the status bar or not. And it is not.
So the problem is not with Layout, I guess.
EDIT 2
this is the desired result
In style-v21 you are overriding the style AppTheme.NoActionBar, but you said the style you use in your activity is the AppTheme style.
You need to override the AppTheme layout in style-v21 or define AppTheme.NoActionBar in you activity.
How can I remove this extra space between the icon in action bar?
See the picture please.
Tried everything, nothing seems to work:
<style name="Widget.Toolbar" parent="#style/Widget.AppCompat.Toolbar">
<item name="android:paddingRight">0dip</item>
<item name="android:paddingLeft">0dip</item>
<item name="android:background">#color/actionBarBackgroundColor</item> <!-- v11 -->
<item name="background">#color/actionBarBackgroundColor</item>
<item name="android:width">48dip</item>
</style>
You can achieve this through style , Try this
<style name="AppTheme" parent="android:Theme.Light">
<item name="android:actionButtonStyle">#style/ActionButtonStyle</item>
</style>
<style name="ActionButtonStyle" parent="#android:style/Widget.Holo.ActionButton">
<item name="android:minWidth">0dip</item>
<item name="android:paddingLeft">0dip</item>
<item name="android:paddingRight">0dip</item>
</style>
Update your manifest as
android:theme="#style/AppTheme" >
You can do this my updating actionbar theme like I did, i was using appcomp theme. You need to play with Widget.Toolbar style, like I added padding on both side of actionbar.
<style name="AppTheme" parent="AppTheme.Base">
<item name="toolbarStyle">#style/Widget.Toolbar</item>
</style>
<style name="Widget.Toolbar" parent="#style/Widget.AppCompat.Toolbar">
<!-- 16dp padding on both sides of actionbar -->
<item name="android:paddingRight">16dp</item>
<item name="android:paddingLeft">16dp</item>
</style>
Update:
The padding on left will not work because Android set size for icon (if i am not wrong) to ~56dp, and actual image is scaled to fit centerInside, which leaves padding within image. So try reducing icon size (width) in style
This is how I solved using Toolbar from appcompat:
Style:
<style name="Theme.ProTaxi.Passageiro" parent="Theme.AppCompat.Light.NoActionBar"></style>
On the activity:
Toolbar actionBar = (Toolbar) findViewById(R.id.actionBar);
actionBar.setTitle("Title");
actionBar.setSubtitle("Subtitle");
actionBar.setTitleTextColor(Color.parseColor("#846A1A"));
Create a xml file in /layout folder with toolbar and included in each of activity xml:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:id="#+id/toolbarLayout"
android:layout_height="wrap_content"
android:orientation="vertical" >
<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/actionBar"
android:layout_width="fill_parent"
android:background="#color/actionBarBackgroundColor"
android:layout_height="?attr/actionBarSize"
app:contentInsetEnd="0dp"
app:contentInsetStart="0dp" >
</android.support.v7.widget.Toolbar>
<View
android:layout_width="match_parent"
android:layout_height="1dp"
android:background="#A0A09F" />
</LinearLayout>
Including toolbar.xml in activity layout xml:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/RelativeLayout01"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#drawable/background_telas" >
<LinearLayout
android:id="#+id/layoutTopToolbar"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical" >
<include layout="#layout/toolbar" />
</LinearLayout>
<ListView
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/listaTaxisLivres"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_below="#+id/layoutTopToolbar"
android:fastScrollEnabled="true" >
</ListView>
</RelativeLayout>
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_width="match_parent"
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>
<item name="android:actionBarStyle">#style/TransparentActionBar</item>
</style>
<!-- ActionBar styles -->
<style name="TransparentActionBar"
parent="#android:style/Widget.Holo.Light.ActionBar">
<item name="android:background">#android:color/transparent</item>
</style>
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="#android:color/transparent"
app:popupTheme="#style/AppTheme.PopupOverlay" />
Don't forget to write: android:background="#android:color/transparent"
Go to res package and open color.xml.
Set color primary to #00000000.
