acivity_countdown.xml

<?xml version="1.0" encoding="utf-8"?> <linearlayout xmlns:android="http://schemas.android.com/apk/res/android"     android:layout_height="fill_parent"     android:layout_width="fill_parent"     android:orientation="vertical"     android:background="#fd4c0d"     >     <framelayout         android:id="@+id/countdownproress"     android:layout_width="fill_parent"     android:layout_height="wrap_content"     android:layout_weight="1"     android:background="#fd4c0d"     >         <progressbar         android:id="@+id/progressbar"         style="?android:attr/progressbarstylehorizontal"         android:layout_width="match_parent"         android:layout_height="match_parent"         android:indeterminate="false"         android:progressdrawable="@drawable/circular_progress_bar"         android:layout_alignparentbottom="true"         android:background="@drawable/circular_shape"         android:layout_centerhorizontal="true"         android:max="500"         android:progress="0"         ></progressbar>         <linearlayout.../><!--this layout contains text inside circular progress -->     </framelayout>     <framelayout.../><!--this layout contains button under circular progress --> </linearlayout> 

circular_progress_bar.xml

<?xml version="1.0" encoding="utf-8"?> <rotate xmlns:android="http://schemas.android.com/apk/res/android"     android:fromdegrees="0"     android:todegrees="0">     <shape         android:innerradiusratio="2.5"         android:shape="ring"         android:thickness="3dp"         android:uselevel="true">         <gradient             android:angle="0"             android:endcolor="#005b7f"             android:startcolor="#005b7f"             android:type="sweep"             android:uselevel="false">         </gradient>     </shape> </rotate> 

circular_shape.xml(the background drawable)

<?xml version="1.0" encoding="utf-8"?> <shape     xmlns:android="http://schemas.android.com/apk/res/android"     android:uselevel="false"     android:innerradius="145dp"     android:shape="ring"     android:thickness="0.8dp"     >     <solid android:color = "#ffffff"/> </shape> 

i have tried make circular_shape.xml (background of progress bar) scale according screen size according https://stackoverflow.com/a/9362168/3929188. creating bitmap xml drawable challenging me couldn't (noobie developer).

i have tried put background circular_progress_bar.xml blue circle animation goes on top of white circle, failed.

any ideas welcomed!

solved finally. put background drawable of circular progress separate view in framelayout.

acivity_countdown.xml

<?xml version="1.0" encoding="utf-8"?> <linearlayout xmlns:android="http://schemas.android.com/apk/res/android"     android:layout_height="fill_parent"     android:layout_width="fill_parent"     android:orientation="vertical"     android:background="#fd4c0d"     >     <framelayout         android:id="@+id/countdownproress"     android:layout_width="fill_parent"     android:layout_height="wrap_content"     android:layout_weight="1"     android:background="#fd4c0d"     >         <imageview             android:id="@+id/progressbackground"             android:src="@drawable/circular_shape"             android:layout_width="fill_parent"             android:layout_height="fill_parent"             ></imageview>         <progressbar         android:id="@+id/progressbar"         style="?android:attr/progressbarstylehorizontal"         android:layout_width="fill_parent"         android:layout_height="fill_parent"             android:layout_gravity="center"         android:indeterminate="false"         android:progressdrawable="@drawable/circular_progress_bar"         android:layout_alignparentbottom="true"          android:layout_centerhorizontal="true"         android:max="500"         android:progress="0"         ></progressbar>         <linearlayout.../><!--this layout contains text inside circular progress -->     </framelayout>     <framelayout.../><!--this layout contains button under circular progress --> </linearlayout> 

circular_progress_bar.xml (drawable)

<?xml version="1.0" encoding="utf-8"?> <rotate xmlns:android="http://schemas.android.com/apk/res/android"     android:fromdegrees="0"     android:todegrees="0">     <shape         android:shape="ring"         android:thickness="3dp"         android:uselevel="true">         <gradient             android:angle="0"             android:endcolor="#005b7f"             android:startcolor="#005b7f"             android:type="sweep"             android:uselevel="false">         </gradient>     </shape> </rotate> 

circular_shape.xml(the background drawable)

<?xml version="1.0" encoding="utf-8"?>  <shape xmlns:android="http://schemas.android.com/apk/res/android"     android:uselevel="false"     android:shape="ring"     android:thickness="0.8dp" >     <solid android:color="#ffffff"/> </shape> 

this made scale according mobile screen size. size small. had little more big. added code in oncreate()

        framelayout frame=(framelayout) findviewbyid(r.id.countdownproressframe);         linearlayout.layoutparams lp = new linearlayout.layoutparams(displaymetrics.widthpixels +150 , displaymetrics.heightpixels-300);         lp.weight = 1;         lp.gravity = gravity.center;         frame.setlayoutparams(lp);         imageview img=(imageview) findviewbyid(r.id.progressbackground);         framelayout.layoutparams framelp = new framelayout.layoutparams(displaymetrics.widthpixels +155 , displaymetrics.heightpixels-280);         framelp.gravity = gravity.center;         img.setlayoutparams(framelp); 

hope helps someone. :)
