here styles.v21 (i dont have have in regular styles.xml file)

<style name="frontiertheme" parent="theme.appcompat.light.noactionbar">         <item name="android:colorprimary">#5f021f</item>         <item name="android:colorprimarydark">#5e152c</item>         <item name="android:coloraccent">#bcbcbc</item>         <item name="android:textcolor">#ffffff</item>     </style> 

and here android manifest.

<manifest xmlns:android="http://schemas.android.com/apk/res/android"     xmlns:tools="http://schemas.android.com/tools"     package="com.daprlabs.swipedeck" >  <uses-sdk         android:minsdkversion="7"         android:targetsdkversion="23" />   <application         android:allowbackup="true"         android:icon="@mipmap/ic_launcher"         android:label="@string/app_name"         android:largeheap="true"         android:supportsrtl="true"         android:theme="@style/frontiertheme"         android:name=".applicationenvironment">         <activity             android:name=".activitycenter"> <!--android:theme="@style/testtheme" -->             <intent-filter>                 <action android:name="android.intent.action.main" />                  <category android:name="android.intent.category.launcher" />             </intent-filter>         </activity>  <activity android:name=".profileview.profileview"             android:label="frontier" />    </application>  </manifest> 

currently, when collapses, color white...but want hexidecimal: #5f021f

add addonoffsetchangedlistener listener in appbarlayout know if it's collapse or not, , change color using setbackgroundcolor. this:

//set listener know current visible state of collapselayout appbarlayout.addonoffsetchangedlistener(new appbarlayout.onoffsetchangedlistener() {     int scrollrange = -1;      @override     public void onoffsetchanged(final appbarlayout appbarlayout, int verticaloffset) {         //initialize size of scroll         if (scrollrange == -1) {             scrollrange = appbarlayout.gettotalscrollrange();         }         //check if view collapsed         if (scrollrange + verticaloffset == 0) {             toolbar.setbackgroundcolor(contextcompat.getcolor(mcontext, r.color.your_collapsed_color));         }else{             toolbar.setbackgroundcolor(contextcompat.getcolor(mcontext, r.color.other_color));         }     } });
