Problem adding viewPager and inflating gridView in it

[Morteza-Rastgoo]

This is my fragment layout containing StickyScrolView:

<com.emilsjolander.components.StickyScrollViewItems.StickyScrollView
android:id="@+id/sticky_scroll"
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:custom="http://schemas.android.com/apk/res-auto"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="@color/layout_background"
android:orientation="vertical">

<RelativeLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <RelativeLayout
        android:id="@+id/slider_container"
        android:layout_width="fill_parent"
        android:layout_height="@dimen/browse_fragment_slideshow_height"
        android:layout_alignParentTop="true"
        android:gravity="center"
        android:orientation="vertical">

        <com.daimajia.slider.library.SliderLayout
            android:id="@+id/slider"
            android:layout_width="match_parent"
            android:layout_height="@dimen/browse_fragment_slideshow_height"
            android:layout_alignParentTop="true"
            custom:auto_cycle="true"/>

        <com.daimajia.slider.library.Indicators.PagerIndicator
            android:id="@+id/custom_indicator"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignBottom="@+id/slider"
            android:layout_centerHorizontal="true"
            android:layout_marginBottom="10dp"
            custom:selected_color="@color/ahangStyle_color"
            custom:unselected_color="@color/layout_background"/>
    </RelativeLayout>

    <com.astuetz.PagerSlidingTabStrip
        android:id="@+id/tabs"
        style="@style/AhangStyle.Widget.TextView.Bold"
        android:layout_width="match_parent"
        android:layout_height="40dip"
        android:layout_below="@id/slider_container"
        android:background="@color/gray_dark"
        android:tag="sticky-nonconstant"
        custom:pstsIndicatorHeight="5dp"
        custom:pstsShouldExpand="true"/>

    <android.support.v4.view.ViewPager
        android:id="@+id/pager"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_above= "@id/imageView"
        android:layout_below="@id/tabs"/>
</RelativeLayout>
</com.emilsjolander.components.StickyScrollViewItems.StickyScrollView>

and on runtime fill the view pager with fragments containing this layout:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:background="@color/red">

<GridView
    android:id="@+id/gridView"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@color/layout_background"
    android:gravity="center"
    android:horizontalSpacing="0dp"
    android:numColumns="auto_fit"
    android:stretchMode="columnWidth"
    android:verticalSpacing="0dp">
</GridView>
</RelativeLayout>

but viewpager is not shown in runtime and it seems to have height of 0.
I tried setting android:layout_height="wrap_content" for GridView and it's parent but it has the same result.

When i set the viewPager's height to android:layout_height="700dp" or something, it works but the problem is that the height of grid view depends on nomber of items retrieved from server and it is not fixed.

how can i solve this?
