I have to develop one android application.

Here i have to develop grid view layout like:

<?xml version="1.0" encoding="utf-8"?>
  <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:id="@+id/Layout1"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
    <TextView
    android:id="@+id/status"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"

    android:text="Mercuryminds Shoppingcart Application"

    android:textAppearance="?android:attr/textAppearanceMedium"
    android:textColor="#040404"
    android:gravity="center" />

<GridView
    android:layout_height="wrap_content"
    android:id="@+id/gridView1"
    android:layout_width="match_parent"
    android:numColumns="auto_fit"

    android:horizontalSpacing="10dp"
    android:verticalSpacing="10dp">
</GridView>

 <include        
 android:id="@+id/footer"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    layout="@layout/footer" />


   </LinearLayout>

   <?xml version="1.0" encoding="utf-8"?>
   <TabHost
android:id="@android:id/tabhost"

<LinearLayout
    android:layout_width="match_parent"
    android:id="@+id/linearLayout1"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <TabWidget
        android:layout_width="match_parent"
        android:layout_height="wrap_content"

Answer 1

add layout_weight="1" to your gridView and layout_height="0dp"

like this

  <GridView
        android:id="@+id/gridView1"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1"
        android:horizontalSpacing="10dp"
        android:numColumns="auto_fit"
        android:verticalSpacing="10dp" >
    </GridView>
