Align ImageView to top right corner

Question

I have a RelativeLayout with images next to each other. The number of images will be variable.

    <RelativeLayout
        android:id="@id/multipleImages"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:orientation="vertical"
        android:background="@drawable/border">

        <ImageView
            android:id="@+id/multi_image1"
            android:layout_width="20dp"
            android:layout_height="20dp"
            android:scaleType="fitXY"
            app:srcCompat="@drawable/imag1"/>
        <ImageView
            android:id="@+id/multi_image2"
            android:layout_toRightOf="@+id/imag1"
            android:layout_width="20dp"
            android:layout_height="20dp"
            android:scaleType="fitXY"
            app:srcCompat="@drawable/imag2"/>
        <ImageView
            android:id="@+id/multi_image3"
            android:layout_toRightOf="@+id/multi_image2"
            android:layout_width="20dp"
            android:layout_height="20dp"
            android:scaleType="fitXY"
            app:srcCompat="@drawable/imag3"/>

        <ImageView
            android:id="@+id/multi_image4"
            android:layout_toRightOf="@+id/multi_image3"
            android:layout_marginTop="2dp"
            android:layout_width="20dp"
            android:layout_height="20dp"
            android:scaleType="fitXY"
            app:srcCompat="@drawable/imag4"/>

    </RelativeLayout>

I want to add another image (the red rectangle) to the top-right corner slightly above the last image . I tried layout_alignParentEnd but the layout goes full width. Setting negative layout_marginTop the image goes up but is disappears outside the RelativeLayout.

Try this :

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <ImageView
        android:layout_width="50dp"
        android:layout_height="50dp"
        android:layout_alignParentTop="true"
        android:layout_alignParentRight="true"
        android:background="#ff0000" />

    <LinearLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentRight="true"
        android:layout_marginTop="25dp"
        android:layout_marginRight="25dp">

        <ImageView
            android:layout_width="50dp"
            android:layout_height="50dp"
            android:layout_marginRight="10dp"
            android:background="#000000" />

        <ImageView
            android:layout_width="50dp"
            android:layout_height="50dp"
            android:layout_marginRight="10dp"
            android:background="#000000" />

        <ImageView
            android:layout_width="50dp"
            android:layout_height="50dp"
            android:layout_marginRight="10dp"
            android:background="#000000" />

        <ImageView
            android:layout_width="50dp"
            android:layout_height="50dp"
            android:layout_marginRight="10dp"
            android:background="#000000" />

    </LinearLayout>

</RelativeLayout>

You can change margin as per your requirement and have desired result
