LinearLayout with two children of equal width

Question

I'm having some issues getting two children of a LinearLayout to have the same width. This is what I am getting:

And here is my layout xml for the grey box:

<LinearLayout 
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:orientation="horizontal"
    android:weightSum="2"
    android:background="@color/medium_grey"
    >

    <ImageView 
        android:id="@+id/profile_photo"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:src="@drawable/placeholder_profile_photo"
        android:scaleType="fitCenter"
        android:contentDescription="@string/blank"
        android:layout_weight="1"
        />

    <LinearLayout 
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:orientation="vertical"
        android:gravity="center"
        android:layout_weight="1"
        android:layout_gravity="center_vertical"
        android:background="@color/alert"
        >

        <TextView
            android:id="@+id/profile_rate_header"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:text="Rate User"
            />

        <LinearLayout 
            android:id="@+id/profile_action_rate_user"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:orientation="horizontal"
            android:layout_weight="1"
            android:gravity="center"
            >

            <ImageView 
                android:id="@+id/profile_action_rate_up"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:src="@drawable/user_rate_up"
                />

            <ImageView 
                android:id="@+id/profile_action_rate_down"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:src="@drawable/user_rate_down"
                />

        </LinearLayout>
    </LinearLayout>
</LinearLayout>

I was assuming that setting the layout_weight of the children of the root LinearLayout along with a weightSum and width of 0dp would produce the desired effect (image being the same size as the pink 'rate user' section) however this isn't the case.

What am I missing?

Edit:

This is what I want it to look like

The photo and the pink linear layout should be equal widths.

Answer 1

android:weightSum="2" should be on the parent of the two children ImageViews, not on the upper parent. Or else try to set weightsas 0.5 and see if it works.

Also, the widths of the two image views should be android:layout_width="0dp" when using weights like this.

Next, scale up your images to fill space. Details here.

Answer 2

Equally weighted children

To create a linear layout in which each child uses the same amount of space on the screen, set the android:layout_height of each view to "0dp" (for a vertical layout) or the android:layout_width of each view to "0dp" (for a horizontal layout). Then set the android:layout_weight of each view to "1". Refer : http://developer.android.com/guide/topics/ui/layout/linear.html
