try using this as your layout i have checked its working properly.
and make it this file as your app widget provider keep it in res/xml/ directrory
<?xml version="1.0" encoding="utf-8"?>
<appwidget-provider xmlns:android="http://schemas.android.com/apk/res/android"
android:initialLayout="@layout/widget_layout"
android:minHeight="72dp"
android:minWidth="300dp"
android:updatePeriodMillis="300"
android:widgetCategory="keyguard|home_screen" >
</appwidget-provider>
