passing layout_weight reference from dimensions (dimens)

Question

I need to set different layout weights for different screen size devices and I want to pass the values from the dimens file, the problem is that the reference from the dimens file keeps throwing errors

error: Error: Integer types not allowed (at 'progress_widget_item3_weight' with value '9').

or

error: Error: Float types not allowed (at 'progress_widget_item3_weight' with value '9.1').

---

<dimen name="progress_widget_item3_weight">9</dimen>

How do I pass the value from the dimens file for the layout_weight ? Thank you

Instead of dimensions you can use integer to declare and reference integers.

Example declaration in integers.xml:

<resources>
    <integer name="left">1</integer>
    <integer name="right">2</integer>
</resources>

Example reference in layout:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

    <FrameLayout
        android:layout_width="0dp"
        android:layout_height="fill_parent"
        android:layout_weight="@integer/left" />

    <FrameLayout
        android:layout_width="0dp"
        android:layout_height="fill_parent"
        android:layout_weight="@integer/right" />

</LinearLayout>
