android -- hide part of linear layout off-screen to the right

I have two linear layouts inside a parent linear layout. all horizontal. I want all of l_child to show and part of r_child to show; while the rest of r_child will be off-screen to the right. How do I accomplish that? 

<LinearLayout

    android:orientation="horizontal" >

    <LinearLayout
        android:id="@+id/l_child"
        android:orientation="horizontal" >
    </LinearLayout>

    <LinearLayout
        android:id="@+id/r_child"
        android:orientation="horizontal" >
    </LinearLayout>

</LinearLayout>

Layout weights are only for distributing layouts to fill a view, so no overflowing can be done this way.

Assigning layout_width with density independent pixels will result in varied success for different size devices.

So I believe you would have more success adding your layouts programmatically based on the screen size.

See this post for getting the screen width: Get screen dimensions in pixels

Once you have the screen width, you can assign the inner-layout dimensions by pixels (with LinearLayout.LayoutParams), calculated as percentages of the screen width.

If you want the left layout to take up 80% of the screen, use .8*screen_width for the size, and if you want the right layout to then overflow by 20% of the screen, use .4*screen_width for that size.

Try giving the parent LinearLayout a negative right margin. 

android:layout_marginRight="-50dp"

Other solution might be to put the parent LinearLayout inside a ScrollView, and set the widths of children layouts to the desired width. In this case, you'll be able to scroll the right layout back to the screen.

You can try using ViewPager, but I don't know if you can get the "bleeding canvas" effect that you're describing using that UI component.

EDIT: Maybe you can try using Gallery widget.

Is this what you're describing?

Do you mean something like this 

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_weight="1"
android:orientation="horizontal"
>

<LinearLayout
    android:layout_width="0dp"
    android:layout_weight="1"
    android:layout_height="70dp"
    android:layout_gravity="center_horizontal|top">

    <ImageView
        android:layout_width="48dp"
        android:layout_height="48dp"
        android:id="@+id/imageView1"
        android:src="@drawable/ic_launcher"
        />
    <ImageView
        android:layout_width="48dp"
        android:layout_height="48dp"
        android:id="@+id/imageView2"
        android:src="@drawable/ic_launcher"/>
    <ImageView
        android:layout_width="48dp"
        android:layout_height="48dp"
        android:id="@+id/imageView3"
        android:src="@drawable/ic_launcher"/>
</LinearLayout>

<LinearLayout
    android:layout_width="0dp"
    android:layout_weight="1"
    android:layout_height="70dp"
    android:layout_gravity="center_horizontal|top">

        android:layout_marginRight="200dp"
        android:src="@drawable/ic_launcher"/>
    <ImageView
