Android Material Design rounded progress_bar -

i´m working on app wich uses different progress bars, , want them ones in google fit, rounded cornes. have custom drawable each bar different colors, , rounds outside corners not inside corners, can see here: custom drawable is:

<?xml version="1.0" encoding="utf-8"?> <layer-list xmlns:android="http://schemas.android.com/apk/res/android">      <item android:id="@android:id/background">         <shape>             <corners android:radius="@dimen/progress_bar_rounded" />             <solid android:color="@color/progressbarbackground" />         </shape>     </item>      <item android:id="@android:id/progress">         <clip>             <shape>                 <corners android:radius="@dimen/progress_bar_rounded" />                 <solid android:color="@color/progressbargreen" />             </shape>         </clip>     </item> </layer-list> 

an progress bars code is:

<progressbar     style="?android:attr/progressbarstylehorizontal"     android:layout_width="fill_parent"     android:layout_height="@dimen/progress_bar_high"     android:id="@+id/greenprogressbar"     android:indeterminate="false"     android:layout_marginleft="15dp"     android:layout_gravity="center_vertical"     android:progressdrawable="@drawable/custom_green_progressbar" /> 

i use libraries https://github.com/akexorcist/android-roundcornerprogressbar , such simple thing think it´s not worth it. have been looking on different threads, nothing has worked me. idea, without having work .9.png images, if possible?

thanks lot!

use scale tag rather clip:

<?xml version="1.0" encoding="utf-8"?> <layer-list xmlns:android="http://schemas.android.com/apk/res/android">      <item android:id="@android:id/background">         <shape>             <corners android:radius="@dimen/progress_bar_rounded" />             <solid android:color="@color/progressbarbackground" />         </shape>     </item>      <item android:id="@android:id/progress">         <scale android:scalewidth="100%" android:useintrinsicsizeasminimum="true">             <shape>                 <corners android:radius="@dimen/progress_bar_rounded" />                 <solid android:color="@color/progressbargreen" />                 <size android:width="@dimen/progress_bar_rounded"/>             </shape>         </scale>     </item> </layer-list>
