<imageview     android:layout_width="fill_parent"     android:layout_height="match_parent"     android:id="@+id/iv_background"     android:layout_centervertical="true"     android:layout_centerhorizontal="true"     android:focusableintouchmode="true" /> 

how set gradient background color in updateappwidget method? planned way, did not work.

imageview iv_skycolor = (imageview)findviewbyid(r.id.iv_background);     iv_skycolor.setbackground(@drawable/skycolor); 

findviewbyid not work inside updateappwidget method,

updateappwidget(context context, appwidgetmanager appwidgetmanager,                                 int appwidgetid) 

also code can not resolve @drawable/skycolor. how can resolve this?

nevermind, managed make work using,

views.setimageviewresource(r.id.iv_background, r.drawable.skycolor);
