Your idéa is similar to my application in Android Market called Learn Math, looking like this: .

I use a TableLayout with individual TableRows for the images, like this:

<TableRow android:layout_marginTop="5dp">
    <ImageView android:id="@+id/img1" />
    <ImageView android:id="@+id/img2" />
    <ImageView android:id="@+id/img3" />
    <ImageView android:id="@+id/img4" />
</TableRow>

The program itself has private variables for the images, which I change on user selections. Initially it might look like this (following the image above):

public class LearnMath extends Activity {
    private ImageView img1, img2, img3, img4;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        img1 = (ImageView)findViewById(R.id.img1);
        img2 = (ImageView)findViewById(R.id.img2);
        img3 = (ImageView)findViewById(R.id.img3);
        img4 = (ImageView)findViewById(R.id.img4);

        // .png images located in res/drawable folder with lower case names
        img1.setImageResource(R.drawable.six);
        img2.setImageResource(R.drawable.plus);
        img3.setImageResource(R.drawable.zero);
        img4.setImageResource(R.drawable.equals);
    }

I hope this gives you a starting point of your application!
