create android battery widget animated when charging -

i want create battery animated widget when battery charging.i want show images continuously. use imageview below:

 <imageview              android:id="@+id/batterycharging_anim"             android:layout_width="wrap_content"             android:layout_height="wrap_content"             android:gravity="center"             android:layout_centerhorizontal="true"             android:src="@anim/batterycharging" /> 

and batterycharging anim file below:

<?xml version="1.0" encoding="utf-8"?> <animation-list     android:oneshot="false"     xmlns:android="http://schemas.android.com/apk/res/android">     <item android:drawable="@drawable/battery_c_10" android:duration="25" />     <item android:drawable="@drawable/battery_c_20" android:duration="25" />     <item android:drawable="@drawable/battery_c_30" android:duration="25" />     <item android:drawable="@drawable/battery_c_40" android:duration="25" />     <item android:drawable="@drawable/battery_c_50" android:duration="25" />     <item android:drawable="@drawable/battery_c_60" android:duration="25" />     <item android:drawable="@drawable/battery_c_70" android:duration="25" />     <item android:drawable="@drawable/battery_c_80" android:duration="25" />     <item android:drawable="@drawable/battery_c_90" android:duration="25" />     <item android:drawable="@drawable/battery_c_100" android:duration="25" /> </animation-list> 

and here method updating widget:

private remoteviews buildupdate(context context)     {         remoteviews widgetview  = new remoteviews(this.getpackagename(), r.layout.batterywidget_layout);          if(status== batterymanager.battery_status_charging)         {           }     } 

what should next? should put in if block??

i think basic implementation this

updated:

found out can't use animation in remoteviews. can use progressbar in layout , set android:indeterminatedrawable animation , make visible , invisible according battery status
