<?xml version="1.0" encoding="UTF-8"?>
    <FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:orientation="vertical"
             android:layout_width="fill_parent"
             android:layout_height="fill_parent"
             android:background="@drawable/inscreen">
        <ImageView android:id="@+id/clip"

                   android:layout_width="wrap_content"
                   android:layout_alignParentBottom="true"
                   android:layout_marginBottom="95dip"
                   android:layout_gravity="bottom|center"
                   android:src="@drawable/selector"/>
        <ImageView android:id="@+id/catagoryvid"
                   android:layout_height="wrap_content"
                   android:layout_width="wrap_content"
                   android:layout_alignParentBottom="true"
                   android:layout_marginBottom="55dip"
                   android:layout_gravity="bottom|center"
                   android:src="@drawable/selector1"/>
        <ImageView android:id="@+id/search"
                   android:layout_height="wrap_content"
                   android:layout_width="wrap_content"
                   android:layout_alignParentBottom="true"
                   android:layout_marginBottom="15dip"
                   android:layout_gravity="bottom|center"
                   android:src="@drawable/selector2"/>
    </FrameLayout>

Any help?

Thanks.

You should use relative layout for handling such type of problem, In which you can put the controls relatively regardless of screen size.
