How to set background on toolbar in Android
I want to set the background of a transparent toolbar.
<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="@android:color/transparent"
android:theme="@style/ThemeOverlay.AppCompat.Dark"
android:elevation="4dp"
android:id="@+id/tool_bar_org"
android:paddingTop="0dp">
</android.support.v7.widget.Toolbar>
Here is my toolbar layout is not transparent
show only white
toolbar = (Toolbar) findViewById(R.id.tool_bar_org);
toolbar.getbackgroud().setAlpha(0);
setSupportActionBar(toolbar);
Does not work. Could you please tell me how to make it transparent.

This is the theme I used in my project to make the appCompact ActionBar transparent, change it to suit your needs:
<style name="adhoctheme" parent="Theme.AppCompat.Light.DarkActionBar">
<item name="android:actionBarStyle">@style/adhocblack</item>
<item name="actionBarStyle">@style/adhocblack</item>
<item name="android:windowActionBarOverlay">true</item>
<item name="windowActionBarOverlay">true</item>
</style>
<style name="adhocblack" parent="@style/Widget.AppCompat.Light.ActionBar.Solid.Inverse">
<item name="android:background">#0D000000</item>
<item name="background">@color/appcompact_transparent_actionbar_bg</item>
<item name="android:icon">@drawable/logo_header_2</item>
</style>
Where appcompact_transparent_actionbar_bg = #0D000000
Important:
Take a look here to check how folders with different values contain specific style files for rendering in different APIs
