How to stretch three images across the screen preserving aspect ratio?

I need to display three same size images (200 X 100) side by side (no gaps) on top of the screen. They should occupy entire width of the screen and preserve aspect ratio. Is it possible to accomplish that using only layout xml file, or I need to use java code?
Solution shoud be resolution independant... Can anybody post a solution or link for this (or similar) problem? Thanks!

Got it working! But as I said above, you need to create your own class. But it is pretty small. I created it with the help of this Bob Lee's answer in this post: https://stackoverflow.com/questions/2991110/android-how-to-stretch-an-image-to-the-screen-width-while-maintaining-aspect-rat/2999707#2999707

package com.yourpackage.widgets;

import android.content.Context;
import android.util.AttributeSet;
import android.widget.ImageView;

public class AspectRatioImageView extends ImageView {

	public AspectRatioImageView(Context context) {
		super(context);
	}

	public AspectRatioImageView(Context context, AttributeSet attrs) {
		super(context, attrs);
	}

	public AspectRatioImageView(Context context, AttributeSet attrs, int defStyle) {
		super(context, attrs, defStyle);
	}

	@Override
	protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
		int width = MeasureSpec.getSize(widthMeasureSpec);
		int height = width * getDrawable().getIntrinsicHeight() / getDrawable().getIntrinsicWidth();
		setMeasuredDimension(width, height);
	}
}

Now to use it in the XML:

<com.yourpackage.widgets.AspectRatioImageView 
	android:id="@+id/image"
	android:src="@drawable/yourdrawable" 
	android:layout_width="match_parent" 
	android:layout_height="wrap_content"
	android:layout_alignParentTop="true" 
	android:layout_centerHorizontal="true" 
	android:adjustViewBounds="true" />

Have fun!

=====================================

Found another way to do the same only in XML by using android:adjustViewBounds="true". Here an example:

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content" >

    <ImageView
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:adjustViewBounds="true"
        android:src="@drawable/image1" />

    <ImageView
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:adjustViewBounds="true"
        android:src="@drawable/image2" />


    <ImageView
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:adjustViewBounds="true"
        android:src="@drawable/image2" />

</LinearLayout>

Only a minor upgrade to take into account what could possible go wrong: null Drawable or 0 width.

package com.yourpackage.yourapp;

import android.content.Context;
import android.graphics.drawable.Drawable;
import android.util.AttributeSet;
import android.widget.ImageView;

public class AspectRatioImageView extends ImageView {

public AspectRatioImageView(Context context)
{
	super(context);
}

public AspectRatioImageView(Context context, AttributeSet attrs)
{
	super(context, attrs);
}

public AspectRatioImageView(Context context, AttributeSet attrs,
		int defStyle)
{
	super(context, attrs, defStyle);
}

@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec)
{
	Drawable drawable = getDrawable();
	if (drawable != null)
	{
		int width =  MeasureSpec.getSize(widthMeasureSpec);
		int diw = drawable.getIntrinsicWidth();
		if (diw > 0)
		{
			int height = width * drawable.getIntrinsicHeight() / diw;
			setMeasuredDimension(width, height);
		}
		else
			super.onMeasure(widthMeasureSpec, heightMeasureSpec);
	}
	else
		super.onMeasure(widthMeasureSpec, heightMeasureSpec);
}
}

Jake Wharton improves AspectRatioImageView class, you can set dominantMeasurement and aspectRatio via xml. You can find it in the link below.

I don't know about XML layouts and the android API, but the math is simple; find the width of the screen and divide by three. That's the width of each image. Now multiply the width by the original image's ratio of Height to Width. That's the height of each image.

int imageWidth = screenWidth / 3;
float ratio = originalImage.Height / (float)originalImage.Width;
int imageHeight = (int)(imageWidth * ratio);
