Toolbar background drawable dynamic height

I add drawable as background in my toolbar, but the image stretched it to its own height.
Possible solution is restrict toolbar to 56dp or something, but I don't want this, as it also will be used for extended toolbar with tabs.
I want gradient similar behaviour for it, "dynamic height"
<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="#drawable/background_gradient"
android:contentInsetLeft="0dp"
android:contentInsetStart="0dp"
android:minHeight="56dp"
app:contentInsetLeft="0dp"
app:contentInsetStart="0dp"
app:popupTheme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"
app:theme="#style/ToolbarTheme" />

You can set your image as textview background. Use android:background="#drawable/toolbartitle". and setTitle("") in your code.
your final toolbar will look like this:
<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:local="http://schemas.android.com/apk/res-auto"
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:minHeight="?attr/actionBarSize"
android:background="#drawable/toolbartitle"
local:theme="#style/MyMaterialTheme.Base"
local:popupTheme="#style/ThemeOverlay.AppCompat.Light" >
</android.support.v7.widget.Toolbar>

Android AppBarLayout collapse toolbar and show scrim colors without delay

I have a CollapsingToolbarLayout with a parallax image in background, i have set scrim colors programmatically, i want to collapse the toolbar when i start the activity if there's no image to show on background, so on activity start i check if there's no image then i call setExpanded(false, false) on AppBarLayout, but it takes around 2 seconds to show the scrim colors, i need to call any method to force it show the scrim colors right on activity create? Or is there any other workaround to force this scrim colors to show on create?
This is my layout res:
<?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"
xmlns:tools="http://schemas.android.com/tools"
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="270dp">
<android.support.design.widget.CollapsingToolbarLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_scrollFlags="scroll|exitUntilCollapsed">
<ImageView
android:id="#+id/image"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_collapseMode="parallax" />
<include layout="#layout/toolbar"/>
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
<include layout="#layout/content" />
</android.support.design.widget.CoordinatorLayout>

I solved this by calling setScrimsShown(true, false) in CollapsingToolbarLayout right after collapse method

I need to make the above ToolBar transparent. so that we can see the background Image.I have tried different methods. but couldn't find correct solution.
please help.thanks

Most of the times we want the toolbar to be translucent because we want to show content behind it. The problem is that the colors of the content behind the toolbar can collide with the color of the toolbar elements/text (up/back arrow for example).
For that reason you'll see in a lot of implementations that the toolbar is actually not transparent but translucent with a gradient.
You can obtain this with the next code:
<?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"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="#drawable/background_toolbar_translucent" />
background_toolbar_translucent.xml
<?xml version="1.0" encoding="utf-8"?>
<shape
xmlns:android="http://schemas.android.com/apk/res/android">
<gradient
android:angle="270"
android:endColor="#android:color/transparent"
android:startColor="#color/black_alpha_40"/>
</shape>
colors.xml
<color name="black_alpha_40">#66000000</color>
You can play with different values on the gradient, what I've found is that for white elements, the black 40% works fine.
Another thing that you might want to do is to hide the title of the toolbar.
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
And show the up affordance...
getSupportActionBar().setDisplayShowTitleEnabled(false);
Don't worry if you see something like this in the layout preview panel...
It looks very different when is actually overlapping the content:

Here is my solution.
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/AppTheme.AppBarOverlay"
android:background="#00000000">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:popupTheme="#style/AppTheme.PopupOverlay" />

That is my version of how to get the transparent Toolbar without shadow in AppBarLayout. The major problem with the above solutions was when I made the toolbar transparent, the shadow was still cast under it. To make the transparent toolbar with the back navigationIcon in Fragment:
layout_transparent_toolbar_fragment.xml:
<android.support.design.widget.AppBarLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/general_appbar"
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"
android:navigationIcon="#drawable/ic_arrow_back_black_24dp"></android.support.v7.widget.Toolbar>
and in TransparentToolbarFragment:
override fun onCreateView(inflater: LayoutInflater, vg: ViewGroup?, savedInstanceState: Bundle?): View? {
val layout = inflater.inflate(R.layout.layout_transparent_toolbar_fragment, vg, false)
val toolbar = layout.findViewById<View>(R.id.toolbar) as Toolbar
val appBar = layout.findViewById<View>(R.id.general_appbar) as AppBarLayout
appBar.outlineProvider = null
val appCompatActivity = (activity as AppCompatActivity)
appCompatActivity.setSupportActionBar(toolbar)
val actionBar = appCompatActivity.getSupportActionBar()
if (actionBar != null) actionBar!!.setDisplayHomeAsUpEnabled(true)
toolbar.setNavigationOnClickListener { appCompatActivity.finish() }
return layout
}
Actually, the line
appBar.outlineProvider = null
does the job of hiding the toolbar shadow.

Try that:
<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:theme="#style/ThemeOverlay.AppCompat.ActionBar" />
and remove that with end tag:
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/AppTheme.AppBarOverlay">
But don't make it full transparent, you can use color have transparency like #93000000 so it will be like this:
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="#93000000"
app:theme="#style/ThemeOverlay.AppCompat.ActionBar" />

Android CollapsingToolbarLayout Title background

I'm working with the CollapsingToolbarLayout from the new Android Design Support Library.
I have set its title and it is working fine, the only problem I still have is that when you scroll, the text is lost, depending on the image in the background.
What I'd like to do, is set a background to the CollapsingToolbarLayout title, but I haven't find a way to do it.
Is there anyway to achieve this?

Setting up the CollapsingToolbarLayout title in the activity:
CollapsingToolbarLayout collapsingToolbar =
(CollapsingToolbarLayout) findViewById(R.id.collapsing_toolbar);
collapsingToolbar.setTitle("Some title here");
Edit:
Here you can see a sequence of images when I collapse the toolbar. You can see how the title text is not readable. The problem is that I don't have control of the images that I show, so for some images it looks ok, but for others, like this example, it doesn't look good at all and it is not readable. What I had in mind was maybe add some kind of background to the text, so there is always the same color at the back of the text and it is always readable.

Use a text protection scrim(scroll down a bit). My example assumes the title text is white, so some tweaks may be necessary to optimize for your case.
Inside your CollapsingToolbarLayout, add the following after ivBigImage:
<View
android:layout_width="match_parent"
android:layout_height="#dimen/sheet_text_scrim_height_top"
android:background="#drawable/scrim_top"
app:layout_collapseMode="pin"/>
<View
android:layout_width="match_parent"
android:layout_height="#dimen/sheet_text_scrim_height_bottom"
android:layout_gravity="bottom"
android:layout_alignBottom="#+id/image"
android:background="#drawable/scrim_bottom"/>
In your Drawable folder, add:
scrim_top.xml
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<gradient
android:angle="270"
android:startColor="#color/translucent_scrim_top"
android:centerColor="#color/translucent_scrim_top_center"
android:endColor="#android:color/transparent"/>
</shape>
and scrim_bottom.xml
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<gradient
android:angle="90"
android:startColor="#color/translucent_scrim_bottom"
android:centerColor="#color/translucent_scrim_bottom_center"
android:endColor="#android:color/transparent"/>
</shape>
For colors, you should make these darker in initial testing so it's more obvious you have it working, but for production I used:
<color name="translucent_scrim_top">#26000000</color>
<color name="translucent_scrim_top_center">#0C000000</color>
<color name="translucent_scrim_bottom">#2A000000</color>
<color name="translucent_scrim_bottom_center">#0D000000</color>
And for dimensions, I used a height of 88dp.

Use a text protection scrim from the example of Amagi82 and add on the CollapsingToolbarLayout the app:expandedTitleTextAppearance parameter.
<android.support.design.widget.CollapsingToolbarLayout
android:id="#+id/collapsing_toolbar"
android:layout_width="match_parent"
android:layout_height="match_parent"
.
app:expandedTitleTextAppearance="#style/TextAppearance.Design.CollapsingToolbar.Expanded.Shadow"
.
.
app:layout_scrollFlags="scroll|exitUntilCollapsed">
For example add this on you style xml:
<style name="TextAppearance.Design.CollapsingToolbar.Expanded.Shadow">
<item name="android:shadowDy">0</item>
<item name="android:shadowDx">0</item>
<item name="android:shadowRadius">8</item>
<item name="android:shadowColor">#android:color/black</item>
</style>

Edit:
If you want to change the color of the toolbar once it has "shrunk", you need to set the contentScrim attribute of the collapsing toolbar layout to that color:
<android.support.design.widget.CollapsingToolbarLayout
app:contentScrim="#color/[color you want]"
...>
Pointing the value of this attribute to the color you want the toolbar to turn into will solve your issue, as I understand it.
Hope that answers your question!

That's a lot of work do achieve here by writing that much of code.
I achieved that by 2 ways.
1 A simple workaround by using a View with TransparentBlack color
CODE>>
Code explaination:1 The CollapsingToolbarLayout has a style with only a text size.2 Default CollapsingToolbarLayout margin bottom is overridden to 16dp.3. Our header with parallax collapseMode is a RelativeLayout with an ImaveView and a View.4. This simple View with a BG at the bottom of the top header Relative layout with colour of contrast (here #77000000), acts as the BG for CollapsingToolbarLayout's collapsed Title in white color.
<android.support.design.widget.CollapsingToolbarLayout
android:id="#+id/redeem_detail_collapsing_toolbar"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#color/color_window_background"
android:fitsSystemWindows="true"
app:expandedTitleMarginBottom="16dp"
app:expandedTitleTextAppearance="#style/CollapsingTitleStyle"
app:layout_scrollFlags="scroll|exitUntilCollapsed">
<!--header view-->
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_collapseMode="parallax">
<ImageView
android:id="#+id/redeem_detail_top_bg"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
android:scaleType="centerCrop"
android:src="#drawable/splash" />
<!--A view that draws a semi tranparent black overlay so that title is visible once expanded -->
<View
android:layout_width="match_parent"
android:layout_height="48dp"
android:layout_alignParentBottom="true"
android:background="#color/black_transparent" />
</RelativeLayout>
<android.support.v7.widget.Toolbar
android:id="#+id/redeem_detail_toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:layout_collapseMode="pin"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light"
app:title="Redeem" />

Android support Toolbar not displaying custom drawable properly

I'm trying to update my apps ActionBar into toolbar but I encountered some problem on customizing my Toolbar to display a custom drawable.
What I tried so far is to set my xml drawable into the Toolbar but it destroys the whole toolbar and moved the menu button down where I cannot properly see it:
Here's the drawable first:
bg_actionbar.xml
<?xml version="1.0" encoding="utf-8"?>
<layer-list
xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:drawable="#drawable/bg_gradient" />
<item android:drawable="#drawable/icon_logo" />
</layer-list>
bg_gradient is just a 9patch image gradient and same with the icon_logo.
And for my 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/actionBar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="#drawable/bg_actionbar"
app:contentInsetEnd="0dp"
app:contentInsetStart="0dp">
</android.support.v7.widget.Toolbar>
this one pushes my menu button below and has a spacing of about 300dp on left with the icon shrinked in height.
Now I just tried to directly changed the background straight into just the png image (bg_gradient) and same thing happens. I've also tried adding an ImageView inside the Toolbar but same thing it just destroys the whole ToolBar and once again I'm lost on how I can customize this Toolbar further. Anyone has the idea? TIA.
UPDATE:
I tried adding a linear layout on the toolbar to contain the background but still it doesn't display properly on my end:
<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="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="#color/cherry_red"
app:contentInsetEnd="0dp"
app:contentInsetStart="0dp">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#drawable/bg_actionbar"/>
</android.support.v7.widget.Toolbar>
Here's what happened:
Additionally here's what I expected it to be:
Icon should be on center, and 9patch image as gradient since I'm having trouble on XML to have a percentage on the start mid and end colors and the navigationIcon should be on top of the gradient.

Hey i think this will helps because i have an app with something similar
My xml is so:
<android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/custom_toolbar" android:layout_width="match_parent" android:layout_height="56dp"
android:background="#drawable/actionbar_bg" >
<RelativeLayout android:id="#+id/toolbar_logo"
android:layout_width="140dp" android:layout_height="40dp"
android:background="#drawable/ic_logo"
android:layout_gravity="left|center_vertical"
android:clickable="true">
</RelativeLayout>
</android.support.v7.widget.Toolbar>
While the drawable/actionbar_bg is so:
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape android:shape="rectangle">
<gradient android:startColor="#FFFFFF"
android:endColor="#4093A3"
android:angle="90" />
</shape>
</item>
</layer-list>
Hope this helps you.

Use the below sample xml for your layout
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<include layout="#layout/toolbar_home"
android:id="#+id/tool_bar" />
</LinearLayout>
toolbar_home.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout android:layout_width="match_parent"
android:layout_height="wrap_content"
xmlns:android="http://schemas.android.com/apk/res/android">
<android.support.v7.widget.Toolbar
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#drawable/actionbar_icon_bg"/>
<ImageView android:layout_width="40dp"
android:layout_height="40dp"
android:src="#drawable/ic_launcher"
android:layout_centerInParent="true"/>
</RelativeLayout>
In your Activity,
toolbar = (Toolbar) findViewById(R.id.tool_bar);
setSupportActionBar(toolbar); //or setActionBar(toolbar)
To get navigation icon and stuff
toolbar.setNavigationIcon(R.drawable.btn_main_nav_selector);
getSupportActionBar().setDisplayHomeAsUpEnabled(true); // or getActionBar().setDisplayHomeAsUpEnabled(true);

.Use
Gravity on your inner View
hope it helps
