Android View same Width and Height
<p>Following is my xml code. In my <code>LinearLayout</code>. I have two child views , which are aligned using <code>weightSum</code>. I have an <code>ImageView</code> whose Width is aligned properly due to <code>weightSum</code>, but the problem is with its height. I want it's Height to be same dimensions as of its width.
Is there any solution without using static <code>dp</code> values. </p>

<pre><code>&lt;RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:gravity="center"
    android:paddingBottom="5dp"
    android:paddingLeft="5dp"
    android:paddingRight="5dp"&gt;

    &lt;LinearLayout
        android:background="@drawable/background_gradien_yellow"
        android:weightSum="10"
        android:orientation="horizontal"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"&gt;

            &lt;ImageView
                android:layout_weight="6"
                android:id="@+id/startbtn"
                android:textStyle="bold"
                android:alpha="0.8"
                android:textColor="#fff"
                android:text="@string/start"
                android:layout_centerInParent="true"
               android:background="@drawable/background_gradient_circular"
                android:layout_width="match_parent"
                android:layout_height="150dp"/&gt;


        &lt;LinearLayout
            android:layout_marginTop="20dp"
            android:layout_marginBottom="20dp"
            android:orientation="vertical"
            android:layout_weight="3"
            android:layout_width="match_parent"
            android:layout_height="match_parent"&gt;


            &lt;TextView
                android:textColor="@color/White"
                android:id="@+id/tv_challange_title"
                android:textSize="20sp"
                android:text="Early-Bird Challange"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"/&gt;

            &lt;TextView
                android:id="@+id/tv_challange_desc"
                android:alpha="0.5"
                android:textColor="@color/White"
                android:textSize="15sp"
                android:layout_marginTop="5dp"
                android:text="Take 100 steps five times within.. "
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"/&gt;


        &lt;/LinearLayout&gt;

    &lt;/LinearLayout&gt;

&lt;/RelativeLayout&gt;
